Several tools with various uses are equipped with circular or radial blades. These include table saws, circular saws, miter saws, and brush cutters, among others.
These blades usually have between 24 and 80 teeth, which need to be sharpened individually. Each tooth must have exactly the same sharpening to maintain consistent depth. The angle of the tooth surface is also crucial as it prevents the blade from vibrating and oscillating from side to side.
They are made of tungsten carbide, molybdenum carbide, or high-speed steel alloys, which are very hard and require specific machinery and precise calibration.
It is possible to sharpen blades that are not made of carbide but softer steel. They require the same process but with different tools.
