The present invention is a rotary tool cutter tooth having a readily replaceable cutting portion and a tool employing the tooth. The tooth consists of an elongated shank for mounting the tooth on the tool body with a cutter element being bolted to the forward end of the shank. Preferably the back face of the cutter element is vertically grooved to receive the forward end of the shank so that the two are precisely aligned and any forces which tend to rotate the cutter element during use are resisted. The face of the shank that adjoins the cutter element may further be provided with a negative or inverted step which engages a corresponding step across the groove of the cutter element. These steps interlock to resist forces which would tend to translate the cutter element radially outward when in use. The cutter element may be made of a tool steel or other hard alloy, whereas the shank is typically formed from a mild steel.
A circular saw is provided with a disc and tooth holders mounted on the periphery of the disc, with each tooth holder having a pair of legs straddling the disc and fasteners such as bolts and nuts extending through the legs and discs for fastening the holder to the disc. A tooth head is provided with a shank in the form of a bolt which extends through the bore in the holder engaging the tooth head, and the shank and tooth head extend in a tangential axis with the periphery of the disc. Shoulders and platforms are provided on the body of the holder for abutting the tooth head.

A saw tooth of the type having a plurality of cutting edges at one end, the saw tooth rotatable in its mounting on a saw disk to present a fresh cutting edge when needed. Each cutting edge is angled rather than curved. The tooth can have hardened inserts to provide the angled cutting edges.
A milling tooth body for a comminution machine has a working side, oriented in a working direction; a flange side detachably connected to a milling tooth holder of the comminution machine; a tooth tip on the side of a recess; and a base at an end of the tooth body facing away from the tooth tip. A cutter device is in the recess. The flange side on the tooth body is opposite the working side. An entire side of the tooth body, which is oriented in the working direction, is the working side. The tooth tip projects away from the flange side in the direction of a longitudinal axis of the tooth body, perpendicular to the working direction. A first section of the tooth body projects away from the flange side in a direction parallel to and opposite the working direction.
A replaceable cutting tooth for a slashing saw, wherein the tooth includes a pair of upper cutting tips with rearwardly divergent adjacent cutting edges and a pair of lower cutting tips also with rearwardly divergent adjacent pairs of cutting edges, such that each side surface and top surface are provided with shallow V-shaped cutting edges whereby the cutting tips protrude laterally and outwardly from the tooth. As the upper cutting tips wear, the lower cutting teeth will continue to maintain a satisfactory width of the kerf.
