The body member includes an elongated leading surface, an elongated trailing surface and first and second side surfaces. The leading surface, trailing surface and first and second side surfaces terminate in a forward working face having a plurality of inserts. Each insert has a generally cylindrical portion integral a top portion which tapers to a point to form a conical tip. The tips of the inserts are aligned to define a linear cutting line which is inclined with respect to a reference plane perpendicular to the axis of the shank and the axes of the inserts are aligned parallel to form a cutting plane which is inclined with respect to the reference plane.
