Which Way To Turn The Circular Saw

The tool is powered from its own power source. a rechargeable battery. Dust is used to work in hard-to-reach places. Depending on the type of battery used and its charge capacity, the tool may be sufficient for a short working period of 15 to 50 minutes. After which the battery needs to be charged, which lasts about 4 hours.

Advantages:

  • Compactness, mobility;
  • Ability to work in the absence of an external power source.

Limitations:

  • Short working time;
  • High price for models that can work for about an hour.

Stationary circular saw on the bed

A tool of this type will be useful for those who have a small home workshop. The cutting depth, depending on the model, can be from 50 to 140 mm.

A feature of the tool is the presence of a bed, which can be of two types:

Cast. used in the construction of powerful dust, it is characterized by high weight and stability. Installation requires a solid base, preferably concrete.

Prefabricated (welded). used in small machines. Characterized by mobility.

The working table of the tool is made of metal sheet (aluminum, steel or cast iron). The table has a special slot for the working disk. The table surface is equipped with guide rulers for easy cutting of the material.

Advantages:

  • The use of the bed Reduces the vibration of the tool, which increases the quality and accuracy of material processing;
  • Reducing noise levels;
  • The ability to process wider workpieces;
  • Ability to set precise settings for processing workpieces;
  • Dust box (on most models).

Limitations:

  • Limiting the size of workpieces.

Hand circular saw

This type is in greatest demand among home craftsmen due to the combination of compactness and sufficient power, which, depending on the model, ranges from 1.2 to 2.2 kW. Professional models have a power of about 5 kW.

The cutting depth of the proposed tool is from 40 to 70 mm. Some models provide the ability to adjust the cutting angle.

Advantages:

  • Simplicity of design combined with efficiency and high performance;
  • Convenience in work due to light weight and compactness, ease of transportation;
  • Easy to clean.

Limitations:

  • High noise level;
  • Insignificant utilization factor of the disc diameter during operation;
  • Difficulty in controlling the placement of the cutting disc and the workpiece, which reduces the accuracy of the cut.

Additional functions

Most of the models have additional functions that make work easier and more comfortable:

Smooth start. when cutting the workpiece, sharp cuts into the material are minimized, the quality of the cut is increased. Engine service life increases.

Collecting sawdust. the presence in the structure of a branch pipe for connecting a vacuum cleaner.

Laser mark. the laser beam forms the trajectory along which the cut must be made. The beam allows NOT to use the guide bar when working with a circular saw. However, mastering the function requires a certain skill of owning the tool as a whole.

Stationary chip removal system. practical for small workloads where there is no need to connect a vacuum cleaner.

Start blocking. protects the master from accidental starting of the tool (to turn on the saw, press two buttons).

Circular saw selection parameters

Before purchasing a circular saw, you need to clearly determine what tasks will be performed with the tool. Depending on THESE tasks, the choice is made on the type of saw. The selection of the tool is carried out taking into account the most fundamental characteristics.

Cutting depth

This indicator depends to a large extent on the disc used, on the diameter of which the dimensions of the processed material depend. A tool designed for the use of small diameter discs, and will not allow you to accurately cut a large workpiece.

Saws with a cutting depth of 40-50 mm are most popular for performing one-time work. For professional work, where efficiency and quality are important, they purchase tools with a cutting depth of 60-70 mm and more.

Which circular saw to choose

Recommendations for choosing a circular saw for home and garden:

To perform a small amount of work from time to time, you can purchase a tool with a power of 1-1.2 kW.

For construction work at a summer cottage, where spraying of timber, boards, plywood and second lumber is required, you can purchase a circular saw with a power of more than 1.2 kW and a cutting depth of at least 60 mm.

For professional use, you can purchase models with a power of more than 1.2-1.5 kW, with a high speed (more than 5 thousand) and a maximum cutting depth at right angles (more than 60 mm).

If it is necessary to manufacture grooves in blanks, cutouts, you can purchase submerged dust.

When performing work related to the construction of metal structures, where metal cutting is required, you can consider using a circular saw for metal. The advantages of using it are described above.

Types of circular saws

Protection against accidental activation

Inadvertent turning on of the circular saw is so fraught with the creation of a traumatic situation that the designers tried to completely eliminate this possibility. To do this, the saw starts only after pressing two SEPARATE buttons, one of which is often recessed into the plastic of the body.

On many instruments, manufacturers install a separate button that allows you to fix the instrument when turned on. It is useless to look for such a lock on circular dust. safety is above all.

Circular saws by type of electricity supply

Here you need to very carefully evaluate the advantages and disadvantages of each type of instrument:

Network. The bulk of circular saws are powered by 220 volt (household hand-held) or 380 Volt (stationary professional). There are only two drawbacks in them: the need for an electrical network and the ability to get tangled in the wire.

Rechargeable. For such a saw, an outlet is also needed, but only in order to charge the battery. Then it works completely offline, though only for 30-50 minutes, depending on the battery capacity. The main disadvantage of such devices is the battery charging time, which is 5-8 times longer than the battery life.

As a result, taking a high cost, it makes sense to purchase cordless tools only for frequent short-term works in hard-to-reach places, it is much easier to take wireless dust than to lead a temporary power cable. For example, it can be roofing or similar work at high altitudes, where you have to constantly move with the tool.

Circular saws by type of work performed and used materials

Using a conventional circular saw, you can cut various pieces of wood into pieces. A conventional circular saw is able to cut various wood pieces at different angles into pieces. However, there are circular saws for special purposes. Some of them are capable of sinking into wood, others are adapted to work with metal.

Metal circular saw. A saw that is supposed to work with metals should be more powerful and adapted to work with different cutting blades. standard abrasive and high strength. In fact, it is the most versatile tool that allows you to cut any materials: sheets, pipes and profiles made of metal, wooden blanks, plywood, plastic and the like.

Plunge-cut circular saw. This class includes hand-held circular saws and stationary, with a movable saw blade. The cutting edge of such tools can go down to the center of the part and start sawing from this point, which allows you to cut through holes in the workpieces. Such devices are most often used for working with plywood, OSB and similar sheet materials.

A visually noticeable feature of submersible circulars is the absence of an automatic lower protective casing and a special design of the base plate, which allows you to adjust the cutting depth with millimeter accuracy. This allows you not only to make through cuts, but also to make straight and curly (if the saw design allows you to make cuts at an angle) grooves, grooves and slots.

Before choosing a circular saw for wood for your home, it is imperative to consider such devices, since they have maximum versatility.

Disk rotation speed

In most cases, the higher the rotational speed of the circular saw blade, the easier it is to work with. The higher the speed, the better the following characteristics:

  • Less chance of disc jamming in the workpiece.
  • Easier to process dense materials.
  • Less torque needed.
  • Cleaner cutting line.

There are enough of its own nuances. for example, the cleanliness of the cut also strongly depends on the shape and number of teeth on the disc, but basically this is the dependence. In addition, it must be borne in mind that a high rotation speed is an increased temperature at the cutting point, which means that materials like plastic or laminate may end up with melted edges after sawing. If you plan to work with such materials, then the best way out would be to find a circular saw with an adjustable number of revolutions of the disc rotation.

Varieties and selection of the required type of circular saw

To choose the type of circular saw that is suitable for the planned work, you need to introduce yourself to their existing varieties.

Overload protection system

Practice shows that most often overheating of the electric tool motor is not allowed by beginners, but by masters with extensive experience, Who, due to haste or for some other reason, stop “listening” to the state of the engine. In this case, the safety of the windings and their protection from overheating is taken over by the motor overload protection system, which monitors the level of energy consumption and turns off the power when there is a sharp jump in the load on the network.

Rip fence and guide rail

When deciding which hand-held circular saw to choose, and not the last question will be the accuracy of its operation, for which parallel stops and guide rails are used. The first of these is, in fact, an ordinary stand or ruler on which the saw sole rests when it is guided along the workpiece. In general, a good method, but it requires a certain skill in controlling the circular. you have to drive the dust and at the same time press it against the Parallel stop.

The guide rail is a great cutting accuracy, since the tool does not have the ability to “Vilno” to the side during work. To do this, a special groove is provided in the saw sole, with which it is “put on” on a previously exposed guide rail.

If it is necessary to maintain the direction of the cut manually, various sights are used. here is the slotted opening on the base plate to the laser mower line builder, which will show where the saw is “going”.

Slip clutch

When the saw blade stops abruptly, none of the existing braking systems is capable of instantly stopping the engine so that its inertia does NOT create a kickback that rips dust out of the operator’s hands. To protect against such accidents, a slip clutch is used, which, instead of trying to stop the engine, simply breaks the contact between it and the saw blade. The latter remains in the material, while the engine continues to rotate by itself. However, the operator will immediately turn it off, because when the slip clutch is triggered, a short-term “howling” of the motor will occur due to a sharp increase in revolutions from a decrease in load.

The device, principle of operation and application of the circular saw

At first glance, the circular saw device is as simple as possible. a powerful engine, on the shaft of which a cutting metal disc is put on. In the case of stationary tools, the engine can be located separately and transmit force to the working shaft by a belt through a system of pulleys, but hand tools, which are the vast majority of household tools, are made in one housing.

The complexity of the device is added by the need to use high-quality materials, strict adherence to the centering of parts, plus maintaining serious safety measures. The saw blade rotates at high speeds, so neglecting any of the above points will at best lead to tool breakage.

As a result, an impressive number of mechanical-electronic protective and blocking devices are added to the engine and the cut-off wheel, the purpose of which is to instantly stop and de-energize the tool if something goes wrong.

The principle of operation of a circular saw is clear from its design. a rotating disc with teeth cuts the board along which the tool itself is pulled. In the case of a stationary saw, everything happens the other way around. the board is pulled through the circle fixed on the bed and divided into two parts.

There is one important note for the use of a circular saw. it is not suitable for curly cutting and is designed to cut boards and other materials only along a straight mowing line. There are models with an additional graduation of the leading sole, which allows you to set the disc not strictly perpendicular to the surface being cut, but at a certain angle, but the saw is also carried out strictly in a straight line.

According to users, this good hand-held circular saw is versatile, as it can be used to cut wood of different densities. Users especially like safety, which translates into reduced risk of injury. The operator can change the range during operation from 0 to 50 degrees. Users emphasize that when using the equipment, they get an excellent view of the mowing line of the cut, since the design is ergonomic.

An example of using household and professional tools

If you are looking for a handheld circular saw, which one to choose, you can decide by reviewing the recommendations below. If you use a professional model, then in 1.5 hours of continuous work you will be able to cut such a number of chipboard blanks, which will be enough to assemble 4 cabinets. If you use a regular household model, then the same work will take 2 times longer. The quality will remain at its best, but the cost of a professional tool will be 2 times higher.

The power button lock is used to prevent accidental starting. Increased stability is guaranteed by a large metal wide support. There is a special compartment for storing the key.

Battery Saw Performance Overview

If you prefer autonomy, then it is best to choose a battery model, however, you should be prepared for less performance. Among other things, the rotational speed will also be significantly lower than in electric circulars. Such models perfectly cope with wood of small thickness and low density. As practice shows, the battery charge may be enough for 30-50 minutes of operation, after which the battery will need to be charged. This can cause some inconvenience, since charging sometimes takes up to 4 hours.

Good hand-held circular saw. How to choose a circular saw: tips and tricks

Previously, only a circular saw was found at the sawmill. Many private craftsmen are already thinking about which model of such equipment to choose. If you also decide to acquire a similar device, then it is important to consider the main characteristics, among which, for example, a power supply.

Model Specifications

One of the most important parameters is the power, which in this case is 2100 W. The cutting depth is 100 millimeters, and the rotation speed is equivalent to 3800 rpm. The size of the circle used is 270×30 millimeters, the weight of the device is 9.4 kilograms. For more convenient work, there is a soft start function, which ensures accurate cutting. Safety is guaranteed by instant engine stop due to electronic brake.

The equipment is equipped with a sturdy and reliable die-cast aluminum support base. The operator will not be faced with the problem of a jammed disc, as there is a riving knife in the device. Safety in the operation of such tools is above all, in this case it is ensured by protection against accidental starting, which became possible thanks to a fuse switch.

Recommendations for choosing a model depending on engine power

Quite often, in the process of carrying out repairs or construction work, a hand circular saw is needed. After reading this article, you will decide which one to choose. The consumer should also take into account the fact that the tool can have a motor of different power. With higher parameters of the motor, the equipment will be able to cut material and high-density products in a short time. The operator will have no difficulty in cutting. The powerful engine is NOT afraid of even knots in the wood. But low-power circulars have a significant advantage, which is expressed in insignificant weight. Thanks to this, the tool can be carried from place to place. Thus, models with a capacity of 2000 watts or less will weigh about 7 kilograms. If the saw is characterized by a power of 1200 watts, then the weight will be reduced to 4 kilograms. Do you need a hand circular saw for household tasks? Which one to choose? Price. An important factor when buying. For private use, models with a power of 1000 to 1200 watts are excellent. If the tool is not used professionally, then the power reserve will remain unclaimed. The cost of the product will also depend on this parameter, the difference in price can reach 100 or more percent.
