Title: Method of forming a wood boring tool

Abstract: A boring tool for woodworking, and more particularly, a method of manufacturing the cutter head from a blank of cylindrical tool steel bar stock. The opposite ends of the cylindrical blank are turned to the desired radius for the cutter head, a transverse internally threaded recess is provided along a diameter of the blank at its mid-length, and the blank is machined to provide a central hub surrounding the recess with oppositely directed radial arms extending therefrom. The surface of the blank opposite the recess is faced to provide cutting edges, and a shank and lead screw are fixed in the recess.
