Abstract
An auger bit includes a shaft having a central axis, a cutting insert mounted to said shaft, and a feed screw that is separate from the cutting insert and which is mounted to the shaft. The cutting insert and the feed screw are engaged with each other. A single locking member, such as a set screw, secures the feed screw member to the shaft, and thereby secures the cutting insert to the shaft. If the feed screw or the cutting insert become worn, feed screw or the cutting insert can be replaced.
