Abstract:

A cutter apparatus is configured for cutting into an edge of a metal sheet and for adjusting a precise depth of cut. A motor drives a cutting tool, preferably a rotary file, in axial rotation. A guide plate supports the motor with the cutting tool extending through a hole in the guide plate. A guide bar is fixed to the guide plate and the guide bar presents a guide bar surface which is orthogonal to a guide plate surface so that when the edge of the metal sheet is pressed against the guide bar surface with the metal sheet abutting the guide plate surface, the cutting tool is positioned for cutting into the edge of the metal sheet. The cutting tool is able to be moved relative to the guide bar surface to determine a depth of cut.
