The woodworking saw blade, which looks like a fire wheel, is an indispensable cutting tool in the process of wood product processing. It is composed of a body and a hard alloy blade head. A woodworking saw blade includes multiple parameters such as the type of blade head, the diameter of the body, the number of teeth, thickness, and hole diameter.

The body of a woodworking saw blade is commonly made of carbon tool steel (T9,T10) and high-speed steel, while the hard alloy blade head is commonly made of tungsten-cobalt (GY) and tungsten-titanium (YT). Tungsten cobalt type hard alloys have high hardness and strong impact resistance, and are widely used in woodworking saw blades.

Saw blades of the same size all have different numbers of teeth. The more teeth a saw blade has, the smoother the cutting surface will be, but the friction is greater, it is more laborious, and the processing noise is louder. There are many openings and round holes on the saw blade. When the saw blade cuts materials at high speed, it generates a large amount of heat. Metals expand and contract due to heat and cold. Increasing the openings allows the saw blade to freely expand and contract at high temperatures, which can prevent the saw blade from deforming.

The commonly used tooth profiles include flat teeth, step-flat teeth, dovetail teeth, left and right teeth, and inverted step-shaped teeth

The left and right teeth are the most widely used, featuring fast cutting speed, sharp sawteeth and good cutting quality. It is suitable for cutting wood, hard solid wood, density board and multi-layer board.

Trapezoidal flat teeth are a combination of trapezoidal teeth and flat teeth. During cutting, they can reduce the phenomenon of chipping teeth and are suitable for cutting artificial boards and fireproof boards.

The inverted ladder teeth are suitable for slotting thick wood boards, and then the main saw completes the cutting process. To prevent the saw blade from cutting too thickly and chipping the edge.
