Patent abstract
A rotatable tool has a tool body that is generally symmetrical about a longitudinal axis, an enlarged cutting head, and a rearwardly extending shank. The shank joins the enlarged cutting head at an annular flange having an annular inner portion contiguous with the forward end of the shank and an annular outer portion contiguous with the outer circumference of the enlarged cutting head. The annular flange is not planar. Instead, the annular inner portion of the flange is positioned axially forward of the annular outer portion.
