SAW TOOTH MOUNTING SYSTEM AND SAW TOOTH

摘要

A saw blade has a rotatable body with a plurality of cutting elements mounted around its periphery. The cutting elements have self holding tapered shanks which are received in sockets in holders on the saw blade. The sockets have corresponding tapers. The holders are U-shaped members which straddle the peripheral edge of the body. The shanks are dimensioned so that the holders are slightly deformed when the cutting elements are fully inserted into the holders. This helps to grip the cutting elements tightly in the holders. The holders have bearing surfaces adjacent the sockets . The bearing surfaces bear against faces on the cutting elements when the cutting elements are fully engaged in the holders so that impact forces are primarily borne by the bearing surfaces and not by the sockets.
