REDUCED VOLUME CUTTING TIP AND CUTTER BIT ASSEMBLY INCORPORATING SAME

摘要

A cutting bit includes a body having a head and a shank, a cutting tip attached to a front surface of the head, the cutting tip including a base portion, an upper portion and a tip portion, and a cavity extending into an interior of the cutting tip a distance from a bottom surface of the base portion. The distance the cavity extends into the interior is such that a bottom of the cavity is axially closer to the tip portion than at least a portion of a skirt separating the base portion and the upper portion. The cutting tip is attached by both a mechanical connection and a joining process. An example of a mechanical connection is a post on the front surface of the head of the body inserted into the cavity of the cutting tip. A cutting tip per se, a cutting bit on a mining machine and a method of manufacturing of a cutting bit are also disclosed.
