Fig 44a Filing The Lip To A Cutting Edge

Third, file the top or front of the cutting lip flat. (Fig. 44.) The auger bit is then held as shown in Figure 44A and the bevel filed until the lip is brought to a cutting edge. To get the proper angle at which to file the cutting lip, compare it with the angle on the lips of a new bit. If the screw point of an auger bit becomes marred, it may be improved by running the edge of a triangular file around the thread of the screw.
