circular saw blades
For transverse and longitudinal sawing of wood units of various designs are used (stationary circular saws, end saws angle grinder, etc.). With their help you can get high quality and accurate cutting not only of lumber, but also soft compounds (laminate, aluminum, plastic, polymer, etc.).). The cutting tool for such equipment is a wood saw blade. They differ in many parameters. The quality of the resulting parts, productivity, and durability of the tool depend on the right choice.
Features of the equipment
Obtaining an efficient drive is not enough for productive and precise processing of different materials, because each model performs its own functions. For domestic use, when the work is done occasionally, and its volume is small, you can buy a universal wood disc for angle grinder. But professional work requires specialized tools.
The tool differs in geometric dimensions, material and tooth shape, possible number of resharpening, performance and durability. These are the factors you need to consider before buying one or more wheels.
This blade has replaced a hacksaw, circular saw, etc. Pros and cons.
Good time. It’s been a year since I bought this blade (wood saw blade) called GRAFF Speedcutter and I still can not get excited about it. So I decided to share with you my experiences with it.
Higher demands on safety when working. Failure to provide a clean cut and high accuracy.
It would seem that, come to think of it, another disk for the grinder. What’s there to write about it?? The grinder, aka angle grinder, has long ago turned into a universal tool available to everyone and capable of performing a huge number of tasks. But.
For your information!
To keep your cutting attachments in good condition, they need to be monitored for wear during work. It is important to check the rounding radius of the cutting edge. it must not exceed 0,1. 0,2 mm. Another indication of blunt teeth is the shape of the kerf. the cut is not smooth, and it looks like the teeth are tearing through the wood.
Important to remember! Manual sharpening is not applicable to carbide-tipped discs. these must be sharpened on special machines. Ten times longer tool life than all-metal circular saw blades.
Grinding circular saw blades correctly and in time guarantees good cutting performance, a smooth cut, and compliance with the permissible engine load. It also prevents the teeth of the jig from jamming in the material and kicking back. It’s easy to get the cutting tool back on track if you follow the simple tips outlined in this article. You do not need to pay for sharpening at a sharpening shop or buy a new blade, which saves you money. And necessary for self-sharpening tools can be found in the arsenal of every master. You can buy them in our online store.

Wood circular saw sharpening with your own hands: geometry of angles, machines
How to determine the sharpening angle of a circular saw
The optimum is to have an initial template, according to which the geometry of the cutting edge can be corrected. It is often made of thin-walled stainless steel, less often of thick cardboard.
Carbide tines are made according to GOST 9769-79. But their geometry and geometric dimensions are determined by the manufacturer based on the purpose of the saw. If there is no template, it is necessary to determine the required sharpening angles by yourself. It is advisable to use a pendulum-type angle gauge.
The technology for making the template with your own hands.
- Get a new blade with tips which is completely identical to the blunt one.
- On a hard sheet of cardboard draw precise contours.
- With the help of a pendulum angle gauge determine the initial geometry of the carbide tips.
- Write the data on the template.
How to sharpen a carbide blade with an angle grinder
Sharpening of carbide discs is very easy with a simple device, and such discs serve for many years.

Circular saw sharpener.
It can then be used for self-sharpening with a sharpening machine or provided as a template for companies providing similar services.
Additionally, it is advisable to compare the data with a reference. For saws that are used for longitudinal shaping, the rake angle is normally 15° to 25°. For cross-cutting models it varies from 5° to 10°. On universal models, the rake angle is 15°.
It is important to remember that the rake angle can be negative. Similar models are used for cutting plastic sheets and non-ferrous metals.
How to sharpen circular saws
Any kind of sharpening machine can be used to form a new cutting edge. The important thing is to choose the right emery wheel and use it to get the edge sharpened. For this you need to use corundum or diamond models.
The best option is to use special equipment, designed for the job. But because of its high cost in many cases, its purchase is impractical. An alternative way is to use a sharpening machine with the possibility of changing the angle of the corundum disc.
Never do the sharpening by hand by yourself. Firstly. it takes a very long time. Second. the result will not meet the standards. If there is no possibility to perform the sharpening of the saw blade on wood independently, it is recommended to use the services of specialized companies.
Sharpening with a file
Only after the completion of preparatory work, during which the alignment of the teeth and their height was carried out, the master begins to perform the main operations. Before you sharpen a wood saw, it is fixed. A vice is also used for this.
Next, take a small triangular file with a fine notch or a file. This tool must enter between the teeth along their entire depth.
Every craftsman who works with wood knows how to properly sharpen a hacksaw. After all, he has performed this operation many times. During its implementation, the master performs the following actions:
- Check that the hacksaw is securely clamped in a vise. Tool must not vibrate. To do this, it is clamped as close to the teeth as possible. But they must be easily accessible.
- Hold the file with both hands.
- Determine the sharpening angle by eye. Usually between 15° and 30°. Easier to determine when teeth are not too worn.
- Adopts a comfortable posture so that the work can be carried out as comfortably as possible.
- Places the file so that the angle between him and the hacksaw is from 30° to 45°.
- Start sharpening the tines with even, rapid and precise movements. They are always carried out in one direction only. Usually move from bottom to top. At first they are performed exclusively on one side of the hacksaw.
Important! On each side of the tooth is filed 3 to 5 times. The number of passes are determined individually for each case. Their number depends on the initial sharpness of the file.
In order to sharpen a wood saw to a good quality, always take into account the pressure with which the process is carried out. Usually it is not too hard, but with each stroke the file must remove the metal. It is not allowed to simply wiggle on the teeth.
Now everyone understands how to sharpen a wood hacksaw with a file. For a high-quality performance of the work it is necessary to allocate enough time and patience. But the process itself is uncomplicated.
After the file has gone over all teeth on each side of the saw, check their sharpness. To do this, the cutting edge of the tool is viewed through the sun’s rays. If a shiny appearance appears between the teeth, then the process is well executed. This is usually checked by sawing some wooden workpiece.
Principles and angles of sharpening
There are four main angles of sharpening on the edges of the saw. These, along with the shape of the tooth, can be the major performance characteristics of the tool. To describe each tooth is used:
These specifications may depend on the type and weight of the circular saw, its intended use, and the density of the particular surface.
Based on the parameters mentioned above, it is possible to divide all circular saws into several types:
- For cutting longitudinal holes. When performing this task, a front sharpening angle of 15 to 25 degrees should be used.
- For making cross-cutting cuts. In this situation, the front angle can vary from 5 to 10 degrees.
- Universal sharpening. The saw blade is sharpened at an angle of 15 degrees for all operations.
The size of the angle to be sharpened is not only determined by the saw’s direction of motion, it is also related to the material of the workpiece. If very hard materials have to be cut, the smallest possible angle must be selected. For softer materials, the angle is increased.

Important! If the carbide saw has been in use long enough, the maximum wear can be seen on the top cutting edge. When examining the tooth plane in detail, it can be seen that the front surface of the material suffers the most.
