Step 2 – Sharpen centre point. One edge on each side of the triangular centre point of your spade bit must have a bevelled edge. Match the angle of your file to the angle of the bevel, and then sharpen the cutting edge of the centre point, after that repeat this procedure for the matching edge on the other side of the bit.

11. How to sharpen Auger Bits

auger bit file

First you sharpen the primary cutter. Hold the bit tip with a strong grip using a piece of softwood, and make a number of passes with the file over the cutting edge. Please be cautious at all times not to modify the angle of the bevel as initially sharpened right into the bit. A 2nd bevel, for example on plane irons can be extremely useful.

However do not use it with auger bits. Just file the face of the bevel and not the back side. Generally, the much less material you get rid of, the much better.

auger bit file

Ensure both bit sides are flat on the stone during execution. If the brace end is raised, a small bevel can be cut outside of the edge, making the bit be completely spoiled.

So be very cautious when handling the bits shapes to make sure the side could not be held securely and also accurately flat against the stone.

A sharp auger bit is a pleasure to use and cuts very quickly. For all but the smallest auger bits, the best tool for the job is an Auger file. An Auger file is double ended and both ends are tapered. One end has teeth on the flats and none on the edges and the other end has teeth on the edges and not on the flats.

A sharp auger bit is an enjoyment to use as it cuts really fast. For almost all the auger bits (except for very small auger bits), the very best tool for the work is an Auger file. An Auger file is double ended while the both ends are tapered. One end has teeth on the flats and none on the edges and the other end has the opposite.

auger bit file

When sharpening the cutting blade for drill, it is incredibly essential to file only the top side of the lips. When somebody asks me why their auger bit doesn’t work, this is the reason why. So if you are having issues with bits that will not cut, inspect the bottom part of the cutting lip thoroughly for an additional bevel.
