Abstract

A hand tool apparatus uses a cutting tool with a first width and a tool axis to machine a hole in an object. The hole has a second width at least as large as the first width of the cutting tool. The tool axis passes through a predetermined point on a surface of the object. The apparatus includes an actuating assembly including a housing. The housing contains an axial feed mechanism configured for moving the cutting tool in an axial direction, a spindle motor configured for rotating the cutting tool about the tool axis, and a radial offset mechanism. The radial offset mechanism is configured for moving the axial feed mechanism in a radial direction such that the tool axis is offset from a principal axis. A motor is configured for rotating said axial feed mechanism and the cutting tool about the principal axis.
