Abstract
A chisel gage insert is disclosed having a larger nose radius at the outer end of the insert crest than at the inner end thereby providing more mass on the portion of the insert that contacts the borehole sidewall. The rounded crest also blends with the convex surfaces of the insert extension so as not to have any non-tangential intersections.
