Abstract
A wood boring drill bit assembly includes a cast cutting head body having a front cutting portion, a rear connecting portion and a central longitudinal axis extending from the front portion to the rear portion. A stem extends axially rearward from the rear connecting portion. A pair of helically-shaped wings extend from the front cutting portion in opposed radial directions along the longitudinal axis. Each wing has an axially forward surface, a side surface, a trailing surface, and a machined cutting edge. The cutting head body has a tapered surface extending from the side surface of each wing to the rear connecting portion near the stem to allow for smooth retraction of the cutting head body from a drilled hole.
