(6) Tooth shape

Commonly used tooth shapes include left and right tooth (alternate tooth), flat teeth, flat-triple chip tooth (high and low tooth), conical tooth, Inverse dovetail tooth (hump tooth), and uncommoned industrial grade three Left-right, left-right left-right flat tooth, etc.

1. The left and right tooth are the most widely used, with fast cutting speed and simple grinding. It is suitable for cutting and cross-sawing various soft and hard solid wood profiles and density boards, plywood, chipboard, etc. The left and right tooth equipped with anti-rebound protection tooth are dovetail teeth, which are suitable for cross cutting of various boards with knots; left and right saw blades with negative rake angles are usually used for sawing laminates due to their sharp tooth 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 flat-triple chip tooth is a combination of triple tooth and flat tooth. It is more complicated to grinding. It can reduce the cracking of the laminates during sawing. It is suitable for sawing various laminates,bilaminates and fireproof panels. In order to prevent adhesion,saw blade for aluminum also use flat-triple chip tooth mostly.

4. Conical tooth are often used in the grooving saw blade. When sawing bilaminates, the grooving saw adjusts the thickness to groove processing on the bottom, and then the main saw completes the sawing process of the board, so as to prevent chipping of the cut edge.

In conclusion, the left and right teeth should be selected for sawing solid wood, chipboard and MDF, which can cut the wood fiber tissue sharply and make the surfacce smooth; in order to keep the bottom of the groove flat, use flat tooth or left -right flat tooth;flat-triple chip tooth are generally selected for sawing laminates and fireproof boards. Due to the high cutting rate of computer cutting saws, the diameter and thickness of alloy saw blades used are relatively large, with a diameter  about 350-450mm and a thickness of 4.0-4.8 mm, most of them use flat-triple chip tooth to reduce edge chipping and saw marks.
