Plunge saw for what you need

What is a circular saw for?

When you need to quickly and efficiently cut the workpiece, while obtaining a cleaner cut than a chain saw, it is recommended to use a circular saw. It is designed for cutting boards, wooden boards, slabs, making seams, grooves, etc. In addition to wood, the tool can handle sheet metal and plastic.


Triple a circular saw is not very difficult, which makes it inexpensive and reliable. The shaft of the high-speed electric motor is equipped with a saw blade: there is a stationary cover on top of it, and a sliding cover at the bottom. Special springs press the lower casing to the surface of the workpiece, returning at the end of the work to its previous position. The motor has a handle and a retaining shroud. At the bottom of the tool, a support bed is fixed with a hinge, which rests on the part during cutting. Due to the hinge, it becomes possible to position the saw at different angles to obtain bevel cuts. Most of the models are also equipped with a riving knife installed under the cover behind the disc.What discs are used

The functional variety of the tool is achieved by using a series of discs, each of which has its own purpose. It is most convenient to have several removable saw blades in a set at once, as needs may vary. The most used tool is considered to be a tool for transverse cutting of wooden blanks: it is equipped with many small teeth. For ripping, you need a blade that has wide teeth and deep slots between them: this allows you to better remove sawdust. Fine sawing and sawing wood with a mustache is carried out with a device with a large number of teeth, where the cutting edge has a reverse slope. To cut sheet steel up to 3 mm, a multi-tooth disc is used.Techniques for working with the instrument The circular saw can work in two main modes. cut and cut. In the first case, the cutting of the disk occurs from the side of the edge of the workpiece. In this case, there is a deviation of the protective casing back: at the end of the operation, it returns to its previous position. When plunge sawing, the disc is inserted into the workpiece from above, which leads to the deflection of the movable casing back. The front of the bed rests the tool against the surface of the part. As for the cleanliness of the cut, it depends entirely on the correct selection of the blade.

It is also influenced by its rotation speed and feed force. It is important to choose the most optimal cutting angle. To achieve the maximum cleanliness of the cut, it is important to achieve a more directional movement of the teeth along the surface of the workpiece. In this case, the disk should protrude from the part by no more than 3-5 mm. To make the cutting line as straight as possible, the saw is equipped with a guide rail in the form of a metal plate. It is attached over the surface to be cut.

Advantages and disadvantages

  • The ability to perform longitudinal and transverse cuts significantly expands the scope of use of such models and allows you to perform complex curved cuts. The only limitation when cutting non-standard shapes is the rounding radius. For plunge-cut saws, it should not be too small.
  • Due to the most accurate positioning of the cutting blade relative to the working surface, the material is cut with pinpoint accuracy, which no other type of saw can do.
  • Due to the peculiarities of the location of the working disc, the plunge saw can work directly near the wall, which simple circulars cannot boast of.
  • By equipping all plunge-cut models with a finishing disc, the cuts are completely smooth and neat. Burrs, roughness and small cracks are excluded.
  • Thanks to the equipment of many models with a guide rail, the geometry of the formed cut is not disturbed and the wood is cut as accurately as possible. In addition, to prevent lateral play of the saw blade, the tool design provides for the presence of special eccentrics.
  • The cleanliness of the workplace when working with a plunge saw is due to the presence of a chip sucker, which instantly draws in the formed sawdust and fine wood dust.
  • The high power of 1000 W and more allows cutting wood pieces with a thickness of 6 centimeters or more. In addition, using a plunge model, it is possible to saw plastic and plexiglass, although the main specialization of the tool is woodwork.
  • Many models are equipped with a stepless adjustment of the cutting angle, which is carried out using a screw mechanism. This allows you to quickly and accurately measure the desired angle and no less accurately cut it.
  • The high safety of using the devices is due to the fact that most models are equipped with double protective insulation, electronic motor overload protection and the function of stabilizing the number of revolutions at high loads.

However, like any other electric tool, submersible models also have drawbacks. The disadvantages include too high, in comparison with conventional circular saws, the cost and complexity when cross-cutting too narrow workpieces, if their width does not exceed the support of the saw.

What it is?

The plunge-cut saw is a type of electric circular saw and is designed to cut wood surfaces not only from the edge, but also from the middle of the workpiece. A feature of the device is the ability to adjust the depth of the cut, which is carried out by placing the disc in a predetermined position relative to the base plate.

Thanks to the adjustment mechanism, the depth of the cut can be adjusted down to a millimeter, which cannot be achieved with a conventional tool.

The principle of operation of the plunge-cut saw is quite simple and consists in the following: the operator sets the required depth and the desired inclination of the working disc. Then the tool is turned on, removed from the lock, inserted into the wood and carefully guided along the marked mowing line. When the motor is started, the working shaft begins to rotate together with the disk mounted on it and cuts the surface. Many modern models of plunge-cut saws are equipped with a speed control function, so that the number of revolutions can be changed depending on the type of material being cut.

At the end of the work, when the pressure on the disc weakens, the cutting unit is spring-loaded and hides behind the sole. The area of ​​application of plunge-cut saws is wide enough. The tool is used for making furniture, cutting grooves, cutting shaped openings and gutters in wooden products, as well as for repairing roofs and working with laminated materials.

What are?

Submersible models are classified according to several criteria, the main of which is the way the device is powered. According to this criterion, devices are divided into two types: network and battery. On-line models are powered by an electrical source and offer higher power and performance. The advantages of such models include the absence of the need for regular battery charging and low weight. The disadvantages include the inability to use the tool in the field, as well as in any other places where there is no electricity or access to the outlet is difficult. The rotational speed in network models varies between 4-5 thousand rpm, and the average power is about 2 kW.

Cordless models operate on battery power and are slightly inferior in power to networked models. One battery charge lasts about 50 minutes, which forces you to interrupt the process and waste time charging. A way out of the situation can be a replaceable battery, which allows you to continue working for a while. The battery voltage is typically 36 V and the engine speed ranges from 2500 to 6300 rpm depending on the model. The cutting depth for such devices varies from 38 to 60 mm.

Another criterion for differentiation is the size and weight of the models. On this basis, mini-saws, middle-class models and heavy units are distinguished. Weight indicators directly depend on the engine power and the type of power supply of the device. The more powerful the product, the more it weighs.


The plunge-cut circular saw is slightly different in structure from a conventional circular tool and is equipped with a specialized unit. Thus, the accuracy of cutting and the absence of backlash provides a complex precision mechanism, which significantly increases the cost of the tool. The rest of the saw design is similar to the basic models. The device consists of a sturdy case, where an electric motor is located, during the operation of which the torque is transmitted to a special shaft. A locking device is located on this shaft, which reliably holds the working disc and does not allow it to move relative to the axis of the shaft.

The saw blade, when in a non-working position, is under the protective cover and is located in the same plane with the mounting base. This design allows for more accurate positioning of the tool on the working surface compared to conventional circular models. All controls are located on one panel, which makes working with the device very convenient and understandable.

Some models of plunge-cut saws are equipped with two discs at once, which allows you to cut a board of any width, performing two cuts at once in one pass.

Without exception, all devices are equipped with a spring-loaded bottom base, due to which, if the cutting disc hits a nail or other third-party element, the device will be stopped in time. The features of the plunge-cut saws include the function of tilting the disc, which is especially convenient when it is necessary to manufacture products of complex configuration.

In addition to the standard design and traditional set of functions, many modern devices often have additional options. They do not fundamentally affect the operation of the saw, however, they make its use more convenient and safe. Among them are backlighting, a speed controller, rulers of different sizes and a chip sucker that forcibly removes sawn products.

How is it different from a circular?

The main difference between the plunge-cut saw and the traditional saw is the blade arrangement. It immediately catches the eye and does not allow the models to be confused. If in a conventional saw, although it is closed from above with a protective casing, it is still clearly visible from below, in submersible models it is located above the level of the sole and is completely covered with a casing. The horizontal position of the disc relative to the sole is also different: in plunge-cut saws it is maximally displaced to the edge, while in ordinary saws it is located almost in the middle.

The next difference is the principle of work execution. So, if when using traditional models, filing starts from the edge of the workpiece, then with submersible models it can be started from anywhere. To do this, you just need to set the required cutting depth parameters, unlock the “head” equipped with a spring mechanism, and place the device exactly in the place where you want to go deep into the wood. After the disc is immersed in the material, it is necessary to smoothly guide the device along the contoured mowing line.

Another distinguishing feature of plunge-cut saws is the bar. This allows for even trimming of long boards, which cannot be achieved with a conventional circular, despite its parallel stop.

It should also be noted that the plunge-cut saws have an anti-splinter liner and “clean cut” discs, thanks to which it is possible to form an absolutely smooth surface of the cut and completely eliminate the formation of chips.

Features and selection of plunge saws

  • Device
  • Advantages and disadvantages
  • What are?
  • How is it different from a circular?
  • How to choose?

When processing wood with a power tool, the problem of accurate cutting often arises. Unfortunately, even modern disc models cannot boast of a perfectly executed job. This is due to the impossibility of exercising proper control over the position of the cutting tool relative to the workpiece. To solve the problem of sawing accuracy, a submersible circular saw was invented and launched into production, which immediately gained popularity among woodworkers and became a sales leader.

How to choose?

If the decision to purchase a plunge saw has already been made, then when choosing it, it is recommended to take into account a number of important factors.

  • It is necessary to decide on the type of power supply of the model. So, if the device is bought for building a house, on the site of which there is no electricity, then the battery model should be chosen. Despite the lower, in comparison with network models, operational characteristics, the tool copes with its task quite well and cuts wood no worse than its electric counterpart.
  • The next selection criterion should be the power of the device. So, for home use, you can limit yourself to models with a capacity of up to one kilowatt, while for professional equipment it is better to choose an engine of 2.5 kilowatts. It is also necessary to pay attention to the presence of an emergency shutdown mechanism, which will prevent overheating of the engine due to a sharply increased load.

It will not be superfluous to check the convenience of the control and adjustment mechanisms, as well as to make sure that there are service centers and the availability of spare parts for a particular model.

Operating the TS 55 REBQ plunge-cut saw (TS 75 EBQ)

The name guide rail comes from the original translation of the German word Führungsschiene, which literally translates as guide rail.
plunge, need

First, let’s figure out what elements the guide rail has, and why they are needed.

    Features of the FS guide rail

Chip protection or anti-splinter tape. Protects the workpiece from the formation of chips, which are most often formed when sawing chipboard. This is the most wearing part of the guide rail and must be replaced regularly.

  • Sliding band (anti-friction) reduces friction between the plunge-cut saw and the guide rail, allowing the saw to slide easily on the guide rail.
  • The anti-skid tape is necessary to create increased friction between the guide rail and the workpiece, so that the guide rail is securely held on the workpiece during processing. For even more secure fixation of the guide rail on the workpiece. clamps are used.
  • Auxiliary grooves are used to attach additional equipment and to connect the guide rails to each other.
  • For comfortable work, the length of the guide rail should be at least 400 mm longer than the workpiece length (250 mm in front of the workpiece and 150 mm after the workpiece). In this case, it is possible, if necessary, to completely immerse the saw without sawing into the workpiece at the beginning and finish cutting the workpiece at the end, while the saw will be guaranteed to be on the guide rail with its entire support surface, and the workpiece will be cut.

    If the protection against chipping is worn out, but there is no new one at hand, then you can carefully peel it off the guide rail, because it has a self-adhesive surface, and glue back with an offset of 2-3 mm outward. Then re-file the chip protection. Woo-a-la.

    The standard lengths of the guide rail are 800 mm, 1080 mm, 1400 mm, 1900 mm, 2400 mm, 2700 mm, 3000 mm and 5000 mm. Custom lengths can be cut from a longer standard guide rail. For example, to work with sheet acrylic stone with a standard size of 3600×600 mm, it is recommended to cut a guide rail 5000 mm long into two parts 4000 mm and 1000 mm. In this case, the long part (4000 mm) is used to cut the sheet lengthwise, and the short part (1000 mm) is used to cut the sheet across.

    There is a possibility of joining the guide rails using two connecting plates. An important difference between the FESTOOL guide rails from most competitors is the presence of two grooves for the simultaneous use of a pair of connectors. Splicing the guide rails with a pair of connectors gives a much more bending stability. This advantage is especially evident when milling with a router on the guide rail, when a force perpendicular to the guide rail appears, tending to move this rail and rotate (displace) the junction of the guide rail.

    Before starting to work correctly, the plunge saw must, as the Germans say, “marry” a guide rail, or, more simply, saw the anti-splinter tape. For this purpose, the saw is placed on the guide rail and positioned using two eccentric clamps. By rotating them clockwise and in the opposite direction, it is necessary to find a compromise between the absence of lateral play of the saw on the guide rail and the ease of longitudinal movement of the saw along the guide rail. After the backlash is selected and absent, and the saw slides along the guide rail without excessive force, it is necessary to saw off the splinter tape (protection against chips). The manufacturer recommends placing the guide rail on any suitable base and sawing off the anti-splinter tape (protection against chipping) with the maximum immersion of the saw. The bottom edge of the splinter guard is now always aligned with the cutting edge of the saw, not only with a perpendicular cut, but with all other angle settings.

    How a plunge-cut saw differs from a classic circular saw?

    The difference lies in the construction of the saw. The design of the classic circular saw has a permanently protruding saw blade, covered by a spring-loaded pendulum cover. In the plunge-cut saw design, the saw blade is housed in a cover. At the start of work, the saw blade spins up and the user plunges the saw directly into the workpiece or in front of the workpiece (possible only when using a guide rail) for further insertion onto the workpiece. The German company that came up with this saw design called it according to the principle of the action carried out. Tauchsäge. plunge saw.

    plunge, need

    The plunge-cut saw design is much more convenient than the design of a classic circular saw when cutting sheet materials, when using a saw on a guide rail on a workbench, for example MTF3.

    However, do not attempt to saw off anything weighed against the plunge saw, such as a block or board. It won’t work. This is the field for the classic circular saw. not quite the classic. HK 55.

    To identify which particular saw we are talking about, they have recently used a plunge-cut saw (rarely parquet) when it comes to plunge-cut saws and circular saws, circular saws, hand-held circular saws, saw with a pendulum cover when it comes to the classic hand-held circular saw.

    The main elements of the circular saw

    Hand-type circular saws have a number of irreplaceable parts. We have already said about the disc itself, now we will touch on other important elements. The circular saw runs on electricity, hence certain design features. The handle of the device is made durable; a switch can be located on it together with a lock button. A separate part on the saws is equipped with a special open compartment for ejection of sawdust in a given direction. To ensure safe working, there will always be a robust protective cover over the disc.

    Manufacturers (brands) of plunge-cut saws

    It is impossible to determine which saw is right for you based on the “dry” technical characteristics, because a more powerful saw can cost several times cheaper than a less powerful analogue. That’s because for plunge-cut saws, power doesn’t play a major role.

    Plunge saws from completely different price ranges

    Roughly they can be divided into two weight categories up to 250 Euro. DIY saws and more than 250 Euro saws for professional use. Often in reviews of plunge-cut saws, saws of different categories are compared. the main technical characteristics of all saws are close, which is not correct. An important difference is the reliability of the mechanisms and the availability of special functions. Some DIY saws are made by the same manufacturer under different brands.

    Sawing with a guide rail

    Now it is enough to make two marks on the workpiece through which the cutting line will pass, align the edge of the splinter-resistant tape along them, while the workpiece we need is under the guide rail (on the left), and the departure to the right of the rail is the guide. If necessary, we additionally fix the guide rail using one of the following options:

    • screw clamps,
    • quick-clamping clamps,
    • end clamps Rapid,
    • vacuum suction cups.

    We set the immersion depth of the saw blade in such a way as to cut 4-5 mm deeper than the workpiece. All is ready. Can be sawed.

    Purpose and application of circular saws

    A circular saw. the instrument is not new, it won the hearts of furniture and joinery craftsmen long ago. Outdated name. circular. It comes from the Latin word “cirkule”, meaning “circle”, “circle”, since the saw blade has a perfectly round shape. Often the circular is also called “parquet”, meaning that it is the best at cutting parquet blanks. So, newcomers to the carpentry business, defining for themselves what parquet is, should understand that this is a circular circular saw capable of sawing not only parquet board, but also other sheet materials.

    The saw effectively produces a neat and accurate cut in wood, wood materials, soft metals, plastic varieties, foam concrete blocks.

    The convenience of a circular saw is that it is able to cut not only along a straight mowing line, lengthwise and across, but also at the desired angle with the greatest accuracy. For this, the tool is equipped with a degree and metric scale, tires, rulers, guides.

    One of the types of circular. submersible circular saw, in general, can start cutting not only from the edge of the workpiece, but in any desired place. over, in the submersible circular, not only the depth of cut is regulated, but also its length, and there is also a unique opportunity to cut right next to a vertical obstacle (for example, a wall) with a minimum gap.

    Based on the listed capabilities and functions, the scope of application of circular saws is determined:

    • Woodworking enterprises;
    • Furniture and carpentry shops;
    • Home workshops where furniture, windows, doors, parquet boards are made;
    • Garages and workshops where various household items are repaired and refurbished;
    • Home repair work and even professional repairs;
    • Construction objects of various types.

    What is a circular (circular) saw: types and scope

    Among the cutting power tools there are a couple of such that will never be superfluous in the household. Such lucky ones include a circular saw, or, as it is abbreviated as the master. circular. Circular. this is an electric circular saw, it cuts with a disc with teeth. Initially, this type of circular saw was conceived only for sawing wooden sheet materials. These include plywood, chipboard, laminate. But, if you replace the blade with a corresponding saw blade, then the saw will easily cope with cutting other materials, such as non-ferrous metals, plexiglass, plastic, stone, concrete, tiles.

    You will learn about what a circular saw is for, what types of circulars exist, and where they are used, from this article. I will tell you about the features of the structure and operation of a circular saw, about the various options for its execution, as well as what parameters you need to pay attention to when choosing it for home or for professional tasks.

    How the circular saw works and how it works

    In the most typical design, a circular saw is a hand-operated device. For holding and various manipulations during work, the tool is equipped with handles. But also circular is also called a circular machine, which is installed on the machine or on the floor. We will also talk about them in this article. The main components of a conventional circular saw. this is:

    • A sole that fits snugly against the sheet being cut, without backlash and gaps, and slides over it during cutting.
    • Electric motor. From it, the torque is transmitted through the gearbox to the spindle.
    • Cutting unit. It is represented by a spindle that develops a huge rotational speed and a saw blade with teeth. The cutting blade is half-covered with a protective cover for safe work. For plunge-cut saws, the blade is completely hidden in the casing, which makes it possible to accurately position the saw anywhere in the sheet material for cutting.
    • Two handles (rarely one). With their help, the saw is held, guided, moved along the surface of the sheet to be cut.
    • Chill suction. for removing chips and dust from the working area.
    • Guide rail or fitted guide rail and ruler system.
    • Hinges for turning the disc at the required cutting angle.
    • Work table, expanders, rip fence (in the case of a stationary saw).

    Track Saw VS Circular Saw. How to. DIY

    The spindle speed for a standard circular is 5000-5300 per minute. The diameter of the saw blade ranges from 115 to 250 mm, and for the most powerful stationary saws it reaches 600 mm. The power supply of the electric drive can be network (basically, it is a single-phase 220V network, only for powerful production models. 380V) or rechargeable (from a battery). The power of the electric motor ranges from 600-800 W (household tools) to 1.8 kW (professional saws) and above (industrial circular saws). The maximum cutting depth depends on the power of the motor and can reach 7-8 cm.

    As you can see, the design of the circular saw has no special problems, it is simple to perform and to repair, understandable in operation.

    Varieties of circular saws and their differences

    To choose the circular saw that is most suitable for the task at hand, you need to know that there are different types of circulars. Some of them are ideal for a large woodworking enterprise, others are best suited for simple cuts, and others are relevant for complex cuts of different materials. Among modern circular saws, the following types are distinguished:

      Stationary (desktop) circular. Such a saw is not mobile, it is stationary (stationary), in fact, it is a circular machine. She is very productive in cutting plywood and wooden beams, sawing boards, sheet material and wood-based panels, making transverse and longitudinal cuts. The base is a massive cast iron (sometimes steel) bed and rack. A working table is fixed on the drain, it has a slot in which a large saw blade is located. Above the sharp teeth are covered with a protective cover. The essence of the work is that the saw itself stands motionless, and the material being cut moves towards it, thanks to the movable part of the working table. The stationary saw is very firmly fixed. In addition, the frame gives it a solid weight and structural rigidity. Therefore, the vibration level of stationary circulars is reduced to a minimum. There are no backlashes and fluctuations, so the cut is highly accurate, clean and accurate. By cons we count the same solid weight. they are difficult to transport.

    After familiarizing yourself with the different types of circular saws, you can determine which tool is most suitable for your planned work. Whether you need a powerful professional device, or a simple and cheap household grade, or an expensive cordless file that allows you not to get tied to the network, or a functional plunge saw.

    What to look for when choosing a good circular

    Finally, I will give some tips on how to choose a circular saw, what technical characteristics are important when choosing, what performance indicators you need to pay attention to first of all.

    • The first indicator when choosing a circular saw, like any other saw. this is the power of the installed engine. This parameter affects all other characteristics. It determines both the maximum size of the saw blade, and the depth of cut, and the maximum possible thickness of the sheet material, and its allowable hardness. The dependence is directly proportional. the higher the power, the larger the blade, the deeper the device cuts, the harder the wood can be cut. But there is also an inverse relationship. the more powerful the motor, the heavier it is in weight. Therefore, we are guided approximately like this:
    • For household household work, we take a light file with a power of up to 800 W.
    • For furniture workshops. medium-weight saw, motor from 800 W and above. up to 1.2 kW.
    • Anything that has an electric drive with a power higher than 1.2 kW. these are already heavy professional saws. They are taken for large sawing jobs, for stationary installation.
    • The second important indicator. cutting depth. As I said, it is determined by the engine power. the more powerful it is, the deeper you can cut. You cannot put a large circle on a low-power device. the motor will burn out. And with a small disc, only thin sheets can be cut. Basically, the most popular circular saw models cut 5-6 cm deep. This is with a straight cut, when the blade is at an angle of 90 degrees to the surface. When the blade is tilted at an angle, the cutting depth decreases. Shallowest depth at 45 degrees. It is 3-4 cm. In the most powerful professional circular saws, the depth of the material cut is higher. reaches 7.5 cm.
    • Speed. A good saw has a rotational speed in the range of 5-5.3 thousand revolutions per minute. High rotation speed makes it possible to cut very dense materials, prevents jamming of the cutting nozzle in the workpiece, guarantees a clean and high-quality cut.
    • Sawing at a given angle. handheld portable circulars have this function. It is mandatory for professional saws as well. The angle is generally between 0 and 45 degrees. But there are also more advanced models in which the disc rotation reaches 60 degrees.
    • The ability to cut metals. The function is not available for all saws, only for those for which it is indicated in the passport. The fact is that cutting metal requires good power and the ability to install a different cutting attachment. It is good to saw metal parts and a well-known angle grinder. However, the circular saw cuts straight and at an angle, and is much quieter and safer.
    • What the body is made of. The plastic case made of modern plastic is very sturdy and durable. However, the metal body is of course stronger. It happens in expensive professional-grade models.
    • Allowable disc diameter. The protective cover will prevent the installation of a disc larger than the motor can handle, and this is very good. Smallest nozzle size. 115 mm. Most popular size. 180 mm, professional saws have a 250 mm disc. There are circles with a diameter of 500-600 mm in production.
    • The presence of tires, rulers, guides. Circular saw with guide rail. this is a high cutting accuracy. Often the tire is not included in the kit, but there are slots on the sole of the file for its installation.
    • Availability of additional options. This also includes safety enhancement functions (all kinds of locks, disc brakes, emergency stops). And systems that increase the comfort and quality of cutting. The latter include a smooth start, constant electronics (speed stabilizer under load), a branch pipe for connecting a chip suction, shaving discharge into a bag, laser marking of a mowing line cut.

    With these performance and characteristics in mind, you can easily select a circular model for your home or business. Before choosing, also decide which type of circular saw according to its structure and method of feeding is best for you.
