Types of tooth shapes for alloy saw blades 514

The commonly used tooth shapes for alloy saw blades include left and right teeth (alternating teeth), flat teeth, ladder flat teeth (high and low teeth), inverted trapezoidal teeth (inverted conical teeth), dovetail teeth (hump teeth), as well as industrial grade three left and one right, left and right flat teeth, etc.

1. The left and right teeth are most widely used, with fast cutting speed and relatively simple grinding. Suitable for cutting and sawing various soft and hard solid wood profiles, density boards, multi-layer boards, particle boards, etc. The left and right teeth equipped with anti rebound protection teeth are dovetail teeth, suitable for longitudinal cutting of various boards with knots; Left and right toothed saw blades with negative rake angles are usually used for panel cutting due to their sharp teeth and good cutting quality.

2. The flat tooth saw has a rough cutting edge, a slower cutting speed, and the simplest grinding process. Mainly used for sawing ordinary wood at a lower cost, it is mostly used for aluminum saw blades with smaller diameters to reduce adhesion during cutting, or for slotting saw blades to keep the groove bottom flat. 

3. Ladder flat teeth are a combination of trapezoidal teeth and flat teeth, which are complex to grind and can reduce the phenomenon of veneer cracking during sawing. They are suitable for sawing various single and double veneer artificial boards and fireproof boards. To prevent adhesion, aluminum saw blades often use saw blades with a larger number of flat teeth.
