Auger Drill Bit

The absolute best source for sharpening this tool is Leonard Lee's book, The Complete Guide to Sharpening, Chapter 15. (This is a must-have for any sharpener's library.)

Other notes :

  • Lead screw must extend beyond any spurs or shoulders on the perimeter of the bit..

  • DO NOT change
    1. the center point of the drill bit, or
    2. the diameter of the drill bit (only file the inside of the spurs / shoulders).

  • Grind the minimum off the bit.

I should make something with the fancy new tools I just bought.

Probably best to stay with the drill bit's geometry as supplied by the manufacturer.

If you have a Fine Wood Working membership, the are good instructions from Vic Tesolin.
