Abstract

See full text

An auger includes a body having a first end, a second end, a stem that defines an axis of rotation, and a flute helically wrapped around the stem. The auger also includes a shank at the first end of the body and a cutting head at the second end of the body. The cutting head includes a cutting edge, a cutting face adjacent the cutting edge, and a back taper surface extending from the cutting edge in a direction opposite the cutting face. The back taper surface defines a back taper angle between an axis perpendicular to the axis of rotation and the back taper surface. The back taper angle is a non-zero angle. The cutting head further includes a feed screw extending from the stem along. The feed screw includes a thread having a pitch and a depth. The pitch is larger than the depth of the thread.
