摘要:
An auger bit includes an elongated shaft, a cutting bit, a feed screw, and a locking fastener. The shaft includes a flute extending in a helical manner with respect to a longitudinal axis along at least a portion of the shaft. The shaft further includes a first slot and a second slot. The first slot extends parallel to the longitudinal axis proximate the first end and is aligned with the axis. The cutting bit is removably received in the second slot and includes a first edge. The feed screw includes a shank and a threaded portion. The shank is removably received in the first slot. The feed screw engages the cutting bit to secure the cutting bit relative to the shaft. The locking fastener is coupled to the shaft and engages the shank of the feed screw to secure the feed screw relative to the shaft.
