ABSTRACT:
An insert, especially a hard wear resistant insert, such as an insert of cemented hard metal carbide, for use in a mining tool or the like. The insert is especially adapted for being press fitted into the body of a mining tool or the like but may also be brazed or cemented therein. The insert has a rounded outer end and a flat inner end and tapers inwardly immediately adjacent the flat inner end and is rounded at the periphery of the flat inner end thereby eliminating stress risers in the insert and providing for easier insertion thereof into a bore in a tool body into which the insert is seated.
