ABSTRACT:
A cutting tool assembly which is adapted for use in combination with a drill for cutting a hole in a work piece. The assembly includes a u-shaped blade and a mandrel assembly for fixing the blade to the drill, a dust shield which surrounds the blade and a stabilizer which can be fixed adjacent the blade. In one construction, the blade includes tips which are removably connectable to a wing portion. Also, a coating of wear-resistant material may be applied to the tips so that the blade is self-sharpening during cutting operations.
