The commonly used tooth shapes of alloy saw blades are left and right teeth (alternate teeth), flat teeth, ladder flat teeth (high and low teeth), inverted trapezoidal teeth (inverted tapered teeth), dovetail teeth (hump teeth), and the rare industrial Level three left and one right, left-right left-right flat teeth and so on.                  

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

2. The flat tooth saw edge is rough, the cutting speed is slow, and the grinding is the easiest. It is mainly used for sawing ordinary wood, and the cost is low. It is mostly used for aluminum saw blades with smaller diameters to reduce adhesion during cutting, or used for grooving saw blades to keep the bottom of the groove flat.

3. The ladder flat tooth is a combination of trapezoidal tooth and flat tooth. It is more complicated to repair and grind. It can reduce the cracking of the veneer during sawing. It is suitable for sawing various single and double veneer wood-based panels and fire-resistant panels. In order to prevent adhesion, saw blades for aluminum also use saw blades with more teeth with stepped flat teeth.

4. Inverted ladder teeth are often used in the bottom groove saw blade of the panel saw. When sawing double veneer wood-based panels, the groove saw adjusts the thickness to complete the groove processing on the bottom surface, and then the main saw completes the sawing process of the board, so as to Prevent chipping of the saw edge.

To sum up, the left and right teeth should be selected for sawing solid wood, particle board, and medium-density board, which can cut the wood fiber tissue sharply and make the incision smooth; In order to keep the groove bottom smooth grooving,with flat tooth shape or with left and right flat combination teeth ;Sawing veneers and fireproof boards generally choose ladder flat teeth. Due to the high cutting rate of electronic  cutting saws, the diameter and thickness of alloy saw blades used are relatively large, with a diameter of about 350-450mm and a thickness of 4.0-4.8 Between mm, most of them use stepped flat teeth to reduce edge chipping and saw marks.
