    2020-12-21 · Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded.

    2020-11-17 · The teeth on a mill tooth bit are sometimes “hard-faced” using tungsten carbide. This hard-facing can be on the gauge teeth (for hard formations), the inner teeth (for soft formations), or on both rows. Hard-facing is applied in such a way so that, as the teeth dull, the hard-facing causes a self-sharpening of the tooth. Insert Bits
