Circular Saw Blades with Many Teeth
Circular saw blades with many teeth mean there are more teeth per inch. This type of saw blade is typically used for fine cutting applications. They can cut wood more precisely, and because the cuts are very fine, less friction and heat are generated, thus reducing dust and the roughness of the cut surface. Saw blades with many teeth are suitable for various types of wood (hardwood, softwood, engineered wood) and other materials (plastics, aluminum alloys, copper, etc.).
Circular Saw Blades with Few Teeth
Circular saw blades with few teeth have only a few teeth per inch. They are generally used for applications requiring fast cutting or large-area cutting. Due to the fewer teeth, the cutting speed is faster, but the cut surface may be rougher. Because there are fewer teeth, the pressure on each tooth is greater, which causes the cutting surface to heat up faster. Therefore, saw blades with few teeth are more suitable for cutting thin sheets, plywood, or rough materials.
