Abstract

See full text

A rotary mining tool having a steel body adapted to be driven axially and turned in a rotational arc relative to its axis and being provided with a hardened wear surface with a cutting edge adapted for cutting engagement with a work area under the axial thrust of said tool body, the wear surface and cutting edge being constructed and arranged with a negative rake angle and a negative skew angle to position the wear surface for such cutting engagement under substantially total compression to thereby minimize tensile shear forces that would tend to break or crack the hardened wear surface.
