发明名称 SAW TOOTH
摘要 A saw tooth intended primarily for sawing wood, particularly in one direction of movement, and having a tip which is given an increased thickness in relation to the remainder of the tooth by upsetting or some other method, and bevelled surfaces so arranged that they form one or more oblique cutting edges presenting a clearance angle. The cutting edge or each of the cutting edges is formed by the intersecting line between a bevelled surface on an upper surface on the tooth and an under surface on said tooth. The bevel angle is at least 27 DEG and at most 60 DEG .
