ABSTRACT:
Disclosed is a bit which can be cut both axially and laterally, and which is especially useful to cut an access opening in a sheetrock panel covering an electrical outlet box. The bit self-guides itself laterally around the periphery of the outlet box so that the opening will correspond to the shape of the box. The configuration of the bit permits it to be made in an unusually small diameter so as to minimize the width of the slot it cuts.
