How to sharpen a circular saw blade correctly and at what angle
It tells about sharpening a circular saw blade. How to determine the degree of wear on a circular wheel? Types of teeth. Tools to sharpen the circle correctly, sharpening principles and angles. How to sharpen with a grinder with your own hands at home and using a machine.
Instruments
Sharpening the saw with your own hands is allowed only with the use of special devices. For this, there is a grinding machine that helps to carry out the process on an automatic machine, and not manually. Then the result becomes more accurate.
In addition, other improvised devices are used for sharpening:
- Mounting vise;
- File;
- A piece of wood.
It will not work to replace the listed devices. If at least one of them is not available, then sharpening will not work.
How to determine wear and tear?
Checking the saw blade for wear is an important issue that should be given special attention. Deep damage leads to the inability to sharpen the circle. There are three main signs by which you can understand that the saw needs to be sharpened or replaced:
- Excessive heating of the protective cover and the formation of smoke. The circular saw has a special cover that signals when the saw is blunt by heating. In especially difficult situations, smoke may appear from it.
- Sometimes the saw device involves a mechanical feed (if you need to adjust the pressure with your own hands). In such a situation, wear can be noticed if the pressure has to be increased.
- If carbon deposits and a strong unpleasant odor are formed on the workpiece when sawing wood.
All the situations described above tell the user to sharpen the device.
How to sharpen a circular saw blade correctly and at what angle
The use of circular saws is especially common in construction. Most of the work requires making cuts and changing the shapes and sizes of finished materials. The circular saw helps you tackle these tasks quickly and get quality results. But the instrument is not capable of serving forever, sooner or later it may become dull. It is for this that you need to know exactly how you can sharpen saw teeth in a domestic environment.

Sharpening principles and angles
There are four main sharpening corners on the saw edges. Together with the shape of the tooth, they can be the main performance characteristics of the tool. The following are used to describe each tooth:
- Front and back angle.
- Cut angles of the front and back surfaces.
These characteristics may depend on the type and weight of the circular saw, its purpose, as well as the density of the particular surface.
Sharpening angles in the diagram
Based on the parameters indicated above, all circulars can be divided into several types:
- For slotting longitudinal holes. When performing this task, a rake angle of 15 to 25 degrees should be used.
- For cross-cutting. In this situation, the rake angle can vary from 5 to 10 degrees.
- Universal sharpening. For any operation, the saws are sharpened at an angle of 15 degrees.
The size of the sharpened angle is not only determined by the direction of movement of the saw, it is also related to the material of the workpiece. When cutting through very hard materials, the smallest angle should be chosen. For softer products, the angle increases.
How to sharpen: basic methods
There are two methods available for sharpening circular saws. Manual and machine. In order to sharpen the disc correctly at home, some nuances must be taken into account.
Manual way
Special saw blade sharpening machines are rarely used in a domestic environment because their cost is high. Therefore, in the absence of such a device, you can cope with sharpening with improvised devices, for example, a grinder. In this case, it is forbidden to hold the circle in your hands without fixing it with anything. Otherwise, it will not be possible to achieve a sufficient cutting angle for further work with the material.
To securely fix the circle in the correct position, use a flat stand.
- The surface of the stand coincides with the level of the axis of the grinding wheel;
- On it, the gear wheel is placed in such a way that the sharpening plane becomes perpendicular to the saw blade;
- The design of the device is complemented by a swivel joint.
The stand will help you to comfortably position the saw blade for cutting in relation to the abrasive material. Before starting work, clear markings are carried out. A colored marker is used for this. They draw a mowing line, which will allow the element to be sharpened at the desired angle. The vise will help secure the disc to the surface.

Types of cutting teeth
There are four planes on the surface of the teeth. Front, back and two lateral.
At the moment of intersection with each other, they create a single cutting edge, due to which the sawing of surfaces occurs.
There are several forms of teeth:
- Straight tooth. Most often it is used only for a quick longitudinal cut. During such work, quality and accuracy are practically irrelevant.
- Oblique tooth. The back plane of such a part is inclined to the right or left. On saws, these teeth often alternate, which is why they are called “alternately cut”. These teeth are most commonly used in tools. The size of the corners can be different, this is due to the coating of the treated surface. Wood, chipboard, plastic. They are used for longitudinal and transverse movements. The large angle of inclination on the tools is used when cutting boards with double-sided lamination. This helps to avoid chipping of the material. The larger the chamfered corner, the easier the saw will cut through the surface. But this greatly increases the likelihood of tooth breakage. On some products, the teeth are inclined not only at the back, but also at the front.
- Trapezoidal tooth. The main advantage of this type is that the edge blunts slowly. But they are rarely used separately, usually alternated with straight teeth. During the operation of the device, the trapezoidal teeth are located above the straight ones, therefore, they take on the main (rough) sawing work. Straight teeth for finishing. This saw design is used for sawing plastic, chipboard and MDF.
- Conical tooth. This type of tooth is considered optional because it only helps to cut the lower part of the material (most often laminate). This design allows you to protect the surface from chips and cracks. Bevel teeth usually have a straight front edge, but it can also be concave. This type is used for finishing the saw cut.
How to make a stationary or manual circular with your own hands
A hand-made circular saw is an excellent tool that allows you to solve a large number of household and other tasks. In fact, it is not difficult to make this device on your own, even in that situation, if you do not have any special skills, the most important thing is to understand at least a little the principle of processing metal alloys.
The materials needed for the job can be found in the home workshop or in the garage. So, circular from a circular saw do it yourself is made of the following elements:
- Corner of strong steel;
- Rectangular shaped tube;
- Engine.
The finished circular saw can be positioned on a workbench. If you don’t have one, you will have to make the table yourself. The engine can be taken from an old walk-behind tractor or washing machine.
Compact benchtop machine
Above we talked about how to assemble a hand circular. Now we will tell you how to turn this device into a stationary one. This process involves the manufacture of a U-shaped bed from a pipe, as well as the installation of a transverse arm. The lower ends of the structure should bend horizontally in the direction of the cut. They are bolted to the table. Stability is provided by additional supports.
Lever mobility provided by cutting a horizontal segment into two identical parts, which are fixed to each other with clamps. The saw blade is attached to the vertical element of the bed with clamps.
Circular from an angle grinder
If you have your own “grinder”, it is very good. To create a “circular”, you need to make an axial handle and a sliding stop to the unit. The design of the sliding stop includes a pair of steel angle pieces located on the sides of the saw blade. With the help of nuts and bolts, they are connected by a transverse bundle, and the gap between the working part and the sidewalls of the structure will be provided with washers.
On the “grinder”, you need to pre-tighten the metal band clamp with a screw tie down. Then you need to attach the double-folded metal strip to the holes for the sliding stop. The stand and clamp can be combined, but in this situation the metal strip will be too thick.
Then, in the gearbox of the future tool, you will need to make several holes for the bolts. For this purpose, the body is disassembled, and the points where drilling will take place are indicated. With the help of the holes made, the axial handle is fixed, because the “standard” handle will not allow making a good cut, even if the master has very strong hands.
The handle is created from a metal tube or rod. The designs can be shaped like horns or braces. The ends of the element with which it will be attached to the gearbox must be provided with holes for the installation of fasteners.
You also need to make a barbell that will regulate the process. For this purpose, you need to take a piece of a metal rod, make a loop from one end of it, rivet it slightly and make a hole for the front stop bolt.
From the other end of the rod, you need to make a thread, which will allow you to connect it to the handle. In advance, one strong nut should be screwed onto this thread, and after the structure is assembled, the second. By lowering and pulling them, you can adjust the cutting depth. By the way, if you use a drill instead of a grinder, you can make a similar tool.
Thus, you can independently make a good circular saw out of an ordinary grinder, with which you can cut various materials.
Stationary installation
A machine similar to factory models needs a competent attitude during the assembly process, so you need to take care of all the little things in advance. The desktop version of the “circular” differs from the stationary only in the height of the bed, which is determined by the peculiarities of work and the size of future workpieces. One-time processing can be done using an ordinary table saw, which after work can be easily removed to the pantry or shed. But the master who constantly deals with wood will need a stationary installation. Therefore, he needs to make a table for a circular saw with his own hands.
The circular machine has the following advantages:
- Such equipment allows you to make better and deeper cuts.
- The machine is much more convenient than manual equipment.
From the foregoing, we can conclude that circular saws, made independently, have a completely understandable and simple design, and drawings that can be found on the World Wide Web will greatly simplify the equipment assembly process. Before making a “circular” on your own, you should separately consider all the necessary elements in order to understand the nuances of the functioning and installation of homemade equipment.

Preparation of tools and materials
Having decided to make a table for a hand-held circular saw yourself, you need to take care of the availability of all the materials necessary for work:
- Film faced plywood (9 or 11 mm), size 800 mm by 800 mm;
- Chipboard 16 mm or other sheet material suitable for the manufacture of the case, sheet size 400 by 784 mm. 4 pieces;
- Bars 40 x 40 mm (length depends on the installation method);
- Self-tapping screws;
- Bolts.
Any hand-held circular saw is suitable for such a table. It should be remembered that when attached to the table, the cutting depth decreases by 10–20 mm. So saws with small discs are not suitable for such a table.
Diy circular saw table
A circular saw is used for cutting wood, plastic. Its cutting base is a flat metal disc with a serrated outer edge. Choosing such a tool, everyone decides for himself what kind he needs: desktop, manual, stationary. Many people prefer the manual option. However, in some situations it is necessary to secure the saw. In this case, you can make a table for a circular saw with your own hands, having the opportunity to fix the tool if necessary.
Step-by-step instructions for assembling a circular saw table
1. Manufacturing of the case. The sheet material for the body is cut to size: 400 mm by 800 mm. Parts are fastened using self-tapping screws and bars. It is better to carry out the assembly by pre-drilling the outer parts of the box. The result is a rectangular box without a bottom and a lid. The top of the blocks is then used to secure the plywood sheet.
2. Prepare and fix the plywood top. Slot holes. First, a piece of 800 mm by 80 mm is cut from a sheet of plywood. Next, measurements are taken of the support shoe of the saw that will be mounted on the tabletop. On the back of the plywood, markings are made. You will need 2 center axes. Without them, you cannot perform accurate markup. Then marks are applied to the plywood, corresponding to the dimensions of the support shoe. Then they make such measurements that the circular has: the diameter of the lower protective casing, its thickness, the maximum distance from the edges of the support shoe. In accordance with the obtained dimensions, they put marks and cut out a rectangular hole with a jigsaw.
3. Fixing the saw to the plywood table top. First, 4 holes are made in the shoe. Diameter. 10 mm. Then the tool is installed so that the working part goes into the cut hole. When the saw is aligned, mark the location of the holes. Marks are made in the central part. In order for the tool to stand securely, plow bolts with a countersunk conical head (M8) will be needed for fastening. To install them, you will have to take care of a high-quality deepening of the cap, it can protrude a maximum of 1 mm in an untightened state.
Plywood is drilled from the outside, the diameter of the holes obtained should be 8 mm, and then a countersink should be made under the head. When the holes are ready, the saw itself is installed on the sawing table for the circular saw, the bolts are tightened from the inside using nuts with plastic grovers or spring washers.
4. Fastening the table top to the body. Start button. First, at a distance of 30 mm, holes are made in the corners of the plywood tabletop. Then a hole is drilled in the central part of the bars. The parts are connected using a steel foot M8 by 18 mm. On the side part, the usual “Start. Start” button is installed. An electrical network is laid inside the case, and the button on the instrument itself is clamped.
5. Manufacturing of a thrust beam. A simple circular saw table will become much more convenient if you equip it with a persistent bar. The drawings contain all the dimensions you need. The beam can be made of plywood and secured with full extension furniture rails. The resulting beam should slide over the surface at a 90 ° angle to the cut plane with little clearance.
6. Stop for rip cuts. It is made from an aluminum curtain rod. At 150 mm from the edges, holes are first drilled for the bolts, and then 2 lines are drawn from the bolt attachment point to the axial mowing line. At the intersection and further towards the bolts, 12 mm holes are made at a distance of 30 mm. Tighten the bolts from below with nuts. And according to the drawn lines, they make cuts for the tonic, their width can be seen at.
