Cutting device tooth mounting arrangement

Abstract:

A saw disc assembly includes a circular plate having a mounting lug defining a V-shaped lug mounting profile extending between first and second sides of a tooth mount. A cutting tooth includes a shank-less body defining a cutting profile at a cutting face of the body and a mounting profile at a mounting face of the body having a configuration for complementary engagement with the lug mounting profile. The tooth mounting profile has first and second flat surfaces engageable with the lug mounting profile so that when the tooth is mounted to the lug, the flat surfaces positively resist rotation of the tooth with respect to the lug about the fastener, while a radially inner side of the tooth extending between the cutting and mounting faces is spaced from the lug and the cutting device.
