Abstract
A self-feed bit system includes a shank extending along an axis and configured to be coupled to a tool holder of a power tool and a cutting head couplable to the shank and including a sector shaped base. A radially extending lip is at a leading edge of the sector shape facing in a cutting direction and includes a rake face facing the cutting direction at a rake angle relative to the axis. A radially extending cutting blade is coupled to the radially extending lip and extends axially forward from the base at a first height. An at least partially threaded tip is coupled to the shank and extends axially forward of the cutting blade. Two or more teeth are positioned on a perimeter of the base trailing the cutting blade. Each tooth extends axially forward from the base at a second height that is less than the first height.
