The difference between the alternating and flat teeth of a woodworking saw
The whole tooth tooth alternately around the turn, is used in the wood. The ladder tooth, generally used for cutting aluminum. So choose what kind of tooth shape is based on what cutting material to choose, and not good or bad points
Sawing wood, particleboard, MDF or tooth, can be sharp wood fiber cut, cut smooth; in order to keep the grooving bottom flat, with flat tooth or flat composite tooth; sawing plywood, fireproof board generally choose ladder flat tooth saws because of computer sawing rate, diameter and thickness of the alloy blades are relatively large, about 350-450mm in diameter, 4.0-4.8mm in thickness, most of the ladder flat teeth, in order to reduce the edge collapse, saw.
The flat saw is more rough, and the cutting speed is slow, and the grinding is the most simple. Mainly used for sawing ordinary wood, the cost is lower, more used for smaller diameter aluminum saw blade, in order to maintain cutting to reduce adhesion, or used for grooving saw blade, to keep the groove bottom leveling.
The left and right teeth are widely used, cutting speed is fast, and grinding is relatively simple. Suitable for cutting and crosscut various soft and hard wood materials and MDF, plywood, particleboard etc.. Equipped with anti elastic protection around the tooth is tooth plate for dovetail, longitudinal cutting of various degree; with negative rake angle of tooth saw blade sharp, serrated cutting because of good quality, usually used for veneer cutting.
The tooth used a tooth (alternate teeth), flat teeth, ladder flat teeth (low gear), trapezoidal teeth (inverted conical teeth), dovetail teeth (Tuo Fengchi), and industrial grade does not see more of the three left and right, left and right flat teeth etc..
