Abstract

An apparatus and method are provided for guiding the bit of a rotary hand tool along a corner of a work surface formed by two or more abutting surfaces, through use of a corner cutting apparatus which includes a corner cutting guide having a housing, defining an axis of the housing, and adapted for attachment of the rotary tool with the axis of the rotary tool extending through the housing along the axis of the housing. The housing also includes first and second guide walls, for engaging abutting walls at a corner of the work surface. The first and second guide walls are disposed substantially perpendicular to one another, and have respective outer surfaces which, if projected, would intersect to form a line lying in a common plane with the axis of the housing and oriented at an acute angle to the axis of the housing.
