Circular saws device
The saw blade design is relatively simple.
In addition to the body, which unites all the parts of the tool into a single whole, it includes:
- Electric motor with mechanical gearbox. required for generating and converting torque.
- Saw blade. fixed on the gearbox spindle with a fixing nut, is a consumable that serves directly for making cuts.
- Riving knife platform. provides a secure stop and a consistent angle to the seating surface, and prevents the cutting disc from getting caught in the lumber.
- Protective covers. parts that redirect sawdust ejected when cutting wood downward.
In some models, additional units and mechanisms are installed. So, recently, laser trajectory indicators, sawdust suction systems have gained popularity, and in powerful industrial “circulars”. additional safety covers that exclude accidental injury to workers.
Classification of “circulars” and criteria for their selection
The most obvious criterion for classifying a power tool is power
It is important to take into account that with an increase in the power of a circular saw, its weight and cost inevitably increase, so think three times before overpaying for a top-class tool if you plan to saw it, for example, plywood.
So, according to the power of the “circular” is divided into:
- Low-power (up to 800 W)
- Middle class (800-1500 W)
- High class (more than 1500W)
Finally, the third criterion for classification is the type of power supply of the instrument. Depending on it, circular saws are divided into network saws (connected to a regular household outlet with a voltage of 220 V) and rechargeable ones (they have a power source built into the body). The latter are preferable in the case when there is no centralized power supply near the future place of the main work. But you can not count on long autonomous work. with such engine power for most “circulars” it is limited to 1-2 hours.
Choosing a hand-held circular saw for wood
Working with lumber in small volumes is a task that hand-held hacksaws and jigsaws can quite cope with. But what if you want to get maximum performance in minimum time? An obvious solution is the use of hand-held circular saws, which, firstly, have sufficient power, and secondly, they are distinguished by convenience and mobility, which are not characteristic of stationary sawmills.
We offer you to get acquainted with the classification and design features of circular saws for wood, as well as take a look at the rating of the most popular models of this year.
How to choose a circular saw and discs for it?
Purpose of the tool
In a private house, a circular saw is indispensable, especially when high performance is required from the tool.
Circular saws are used for:
- Pruning large branches and felling trees
- Longitudinal or transverse cutting of boards, beams and battens
- Cutting plastics and soft non-ferrous metals
- Dissolution of sheet materials
Types and features of saw blades
Saw blades differ, first of all, in diameter. the larger it is, the greater the cutting depth the tool can provide
Since the disc can only penetrate into the material up to the level of the support platform, it is usually about 40% of the diameter.
In addition, discs are classified by purpose, for example:
- For soft woods
- For medium and hard rocks
- For sheet lumber
- For aluminum profile
- For plastics, etc.
Selection by purpose
As already found out, there is a wide variety of saws, but the choice of a hacksaw should also be carried out in accordance with certain types of work:
- For rip sawing, a jigsaw must be used.
- The transverse will cope well with wood where there is a transverse arrangement of fibers.
- With a tenon, you can cut various grooves and tenons, as well as technological recesses in the tree.
- Circular cuts holes of various shapes.
- Folding hacksaw is used on trees.
The choice must always be made according to the main purpose for which a certain instrument is purchased. A saw with interchangeable blades is suitable for a household, and it is also desirable to have several types of cutting tools at home.
Hand saw for wood: varieties, which one is better to choose
It is very difficult to do on a private plot or cottage without a hand saw for wood. This tool is also called “hacksaw”. With such a simple device, you can cut trees or branches in the garden, shorten fences and perform many more types of work where you need to change the length of some wooden product: boards, laminate flooring, and so on.
- Choosing a saw
- Tooth size
- Steel
- Blade length
- Lever
It is unlikely that someone seriously thought about this, but if you make the right choice of a saw, then its service life, as well as the convenience of work and the quality of the cut, will depend on it. That is why it is necessary to know all the basic parameters for the correct choice of such a carpentry tool.
Varieties
- Classic. This is the main type of hacksaw that almost every man has in the garage. Even those who have the most distant relation to construction still acquire such a device. This type of saw can be of any length, as well as a different number of teeth. The tool is very often equipped with a replaceable blade that comes with the kit.
- Narrow. Such a hacksaw is also called a circular saw. The name appeared due to its use. with a saw, you can create lines of various shapes, and everything is done very clearly and accurately. Another such device can be used to cut various holes. The blade is very narrow, and the teeth are frequent, they are located both on one working plane and on both. It must be remembered that when working, you need to act very carefully, because if hesitant movements are made, then the blade can easily turn in the other direction. That is why it is advisable to buy a canvas made of high-quality and good steel, which will not bend during operation.
- With a backing. This type of hacksaw for wood is equipped with a stiffening rib, which will not allow the blade to bend while cutting the material. That is why the tool cannot make a low cut, since the backing will interfere with this process. It is worth noting that this type of saw has a very comfortable handle at an angle of 45 degrees. That is why it is very easy to work with the canvas.
- Luchkovaya. This type of saw is very often used in plumbing work. With the help of a hacksaw, you can cut rough parts of the trunk, saw out various figures from plywood, and also remove knots on a tree. Sawing of wood can be performed both transversely and along. The use of a bow saw is very wide, and therefore it can often replace a small woodworking machine. But such a tool has its drawbacks. The saw is rather bulky. It has a complex design, and all bearing parts are made in the form of a curved arc, to which a very narrow canvas will be attached. And also you need to work with the tool very carefully, since the blade is fragile and can very easily break during operation.
- Reward. It takes a lot of effort to get comfortable with this kind of device. This tool resembles a plane. There are several handles. With the help of such a saw, you can cut grooves and spikes, make a depression of different sizes, and on any type of wood.
- Folding saw. This type of instrument is very convenient because you can take it with you on vacation or on a hike. It is very lightweight, compact and folded will not hurt a person. It is worth noting the very small teeth, which are well sharpened.
Lever
Thanks to the handle, the convenience of carrying out any work is carried out. The tool should fit perfectly in the hand and also be very comfortable. To make a handle, different plastics are used, which will be pleasant to the touch. When choosing, you must make sure that the material will not slip if the hand sweats during work. It is for this purpose that special grooves and recesses are made in the handle, as well as rubberized pads. It is these parameters that all manufacturers take into account, and therefore they produce products that differ in a wide variety of handles.
Choosing a saw
- the shape and size of the teeth;
- the size of the canvas;
- the brand of steel from which the canvas is made;
- handle shape.
If one of the specified parameters changes, then the hacksaw saw will radically change its initial characteristics. All these factors must be taken into account when buying a tool for different cases. And also you should always make sure that the saw fits very well in the master’s hand, because this will greatly facilitate the work. It is not worth purchasing a tool with a small handle for a person who has large hands. Such a hacksaw will be very inconvenient to use, and therefore the quality of the cut will suffer.
Steel
No one wants the saw to fail after a few uses, and therefore it is advisable to choose the highest grade of steel. Teeth can be regular or hardened. Ordinary ones are sharpened at home.
Saws with hardened teeth are disposable, because when they wear out, nothing can be done with them on their own. This type is very easy to spot by its dark color. It is advisable to choose a saw that is made of stainless steel, since it can often be very damp in garages, and therefore the saw will be covered with unnecessary corrosion. And there are often situations when work is carried out on the street, but after use the saw is forgotten on the site, then it rains, after which the tool is also covered with rust.
Blade length
This parameter will be determined by the pitch of the teeth and the size of the saw.
- Small hacksaws are equipped with small and frequent teeth, the length of the blade will not exceed 350 mm.
- Universal hacksaws are available with an average tooth size, and the length of the entire tool is no more than 550 mm.
- A wide hacksaw has large teeth and an increased pitch, the blade length is usually no more than 600 mm.
The canvas can differ not only in length, but also in shape. A traditional saw is usually tapered on one side of the rectangle. This suggests that you have purchased a versatile tool that can be used to saw various objects. A rounded blade is usually used to cut branches or other objects from a distance. Such a hacksaw is very light and glides on the wood with high quality, without causing any special trouble to the owner.
Tooth size
This parameter will greatly affect the speed of work as well as quality. To make it convenient to determine the size and number of teeth, the designation TPI was specially introduced, which should indicate the number of teeth in one inch. Such a parameter can always be found in the description of the tool, and also this value is very often drawn directly on the canvas.
- A hacksaw for wood with a large tooth will provide a rough cut, as well as a high speed of work. This parameter will be needed for sawing large boards, firewood and branches. TPI of such a tool is 3. 6.
- If there is a need to make a neat and even cut, then you need to buy a saw with fine teeth. T PI 7. 9. Such a hacksaw is ideal for sawing chipboard, fiberboard, laminate. But it is worth noting that the productivity will be much less than that of a coarse-toothed hacksaw.
The teeth can also differ in their shape, and this will affect the purpose of the tool:
- For rip sawing, the teeth are made in a triangular shape with oblique corners. Their appearance will resemble hooks that are sharpened from 2 sides. Such a saw will slide along the grain of the wood and make the cut very evenly, without leaving any chipping.
- For cross cutting, teeth are made in the shape of an isosceles triangle. This type of hacksaw cuts when going back and forth, but it is advisable to use it only on dry wood.
- Sometimes it is necessary to use a mixed type of sawing, and for this option, two types of teeth are ideal, which are alternately located one after the other. Long curved ones will cut materials in the forward direction, and the triangles, when moving backward, will expand the channel and cling to sawdust and shavings.
Type of food
Circular saws of the manual category can be operated both from the mains and from the battery. As a rule, models with a built-in battery are less powerful and require regular recharging, but they can be used anywhere in the garden. Chain saws are always limited by the length of the cord, they must be turned on near the outlet or pulled to the desired location with extension cords.
Smooth start
If the circular saw is started immediately at full throttle, it will lead to an unpleasant jerk of the device in the hands. In addition, the engine is then subject to wear more quickly. Soft start is responsible for ensuring that the tool starts up and accelerates gradually. The function increases the convenience of use and prolongs the life of the saw.
