Abstract
A non-rotating mining cutter pick has a shank portion with a non-circular cross-section, a head portion including a tip region distal from the shank portion, a shoulder portion separating the shank portion from the head portion, and a cutting insert mounted at a front end of the tip region. The cutting insert includes a body formed of tungsten carbide and an element formed of a superhard material, such as PCD or other material having a prescribed knoop hardness. At least a portion of a first surface of the element is exposed on a cutting surface of the cutting insert, which improves wear properties of the mining cutter pick. The element is fused to the body of the cutting insert, preferably in a high pressure-high temperature (HPHT) process. A method of manufacture and a cutting machine incorporating the non-rotating mining cutter pick on the rotatable element are also disclosed.
