In the second step, sharpen the guide screw of an auger bit. In the third final step, check the sharpening quality of the bit, by drilling a hole with the auger bit.
What is an Auger Bit File?
Auger bit file is the tool used for sharpening auger bits. This metal file has teeth on one side for better sharpening and metal finishing.. An auger bit sharpening file is primarily used to remove unwanted sharp edges and debris through the debugging process.

How to Sharpen an Auger Drill Bit with Auger Bit File
The Auger drill bit sharpening method is mainly divided into two simple processes, the first process involves sharpening auger bit tips/spurs, while the second process involves sharpening guide screws.
Process 1- Sharpening Auger bit tips and spurs
In this step, we will sharpen the tips of your auger bit. The tips are present at the bottom of each spiral round, close to the guiding screw. Start by stroking them with an auger bit sharpening file. Repeat the process several times until the tips are sharp. Be sure to cut the tips at the proper angle.
Process 2 - Sharpening the Guide Screw
After sharpening the auger bit tips and spurs, it's time to sharpen the guide screws. Follow three simple steps to properly sharpen an auger bit screw:
How many scoring spurs does a spiral auger bit have?
Compared to center bits, which have only a single scoring spur and a single cutting lip, spiral auger bits typically have two scoring spurs and two cutting lips that have to be dealt with. The added complexity of the spiral auger bit is that its center point is a threaded lead screw compared to the smooth pyramidal point of the center bit.
Why doesn't my auger bit cut?
On antique auger bits, improper filing of the cutting lips is probably the #1 reason that a bit doesn’t cut well. As mentioned above, when sharpening the cutting lips of an auger bit, it is extremely important to file ONLY their top edges.
What size are Auger bits?
Auger bits were capable of being made in fairly small sizes (down to about 3/16″) without becoming thin and fragile like shell bits. Like center bits, they scored the perimeter of the hole cleanly, preventing chipping around the perimeter of the hole on entrance of the cutting lip.
When were spiral augers invented?
Spiral auger bits for use in a hand brace were developed in the mid-19th century (large T-handle spiral augers for timber framing and ship building were an earlier invention). The Cook’s pattern auger was patented in 1851, followed shortly thereafter by the patent for the Jennings pattern auger, in 1855. Interestingly, while Cook patented his design several years earlier, it was the Jennings pattern that dominated the market in the following years.
Why do you need to fill the top of the cutting lip?
Filing the top of the cutting lip will make the bit cut chips away better and make it easier to turn (especially larger diameter bits).
What is the thin shiny line at the front of the bottom edge of this cutting lip?
The thin shiny line at the front of the bottom edge of this cutting lip is a secondary bevel. This will have to be filed away before the bit will cut well.
Do spurs need to be sharpened?
The spurs need to be very sharp in order to bore a clean hole, but more importantly, they need to be sharpened correctly. Using a small saw sharpening file, or an auger bit file designed specifically for the task, the spurs should only be sharpened on their inside edges.
What is an auger bit file?
This special type of file , helpfully called an auger bit file, has single-cut teeth at either end. At one end, the wide flat faces have teeth, while the edges are smooth without teeth. At the other end, the edges have teeth and the faces are flat without teeth.
What happens if you lift a brace end?
If the brace end is lifted, a slight bevel will be cut on the outside of the edge, and the bit will be permanently ruined! Be especially careful when working with bits whose shape prevents the side from being held firmly and reliably flat against the stone.
Why use a brace and auger bit?

How to remove burr from a bit?
But sometimes a slight burr forms in the process of filing the cutting edges. This burr can normally be removed by simply starting to bore a hole with the bit. But this method sometimes fails. In this case place the bit flat on a fine (at least 3000) grit sharpening stone, and grind it with a circular motion. In the photo a 3000 grit Naniwa Sharpening Stone can be seen in action.
What is the difference between a wide and narrow edge of a file?
Here you see the teeth on the wide face of the file, while the narrow edge is smooth. At the other end of the file, the narrow edge has teeth , while the wide faces have none. Normally you’d use the wide toothed faces, but for very small bits, or for bits with an unusual shape, you’d use the narrow edges to do the sharpening.
Can you bevel a back bit?
Important: be careful not to alter the angle of the bevel of the original bit. A back bevel can be very useful, for instance, on plane blades. But on auger bits a back bevel is out of place. Only file the face of the bevel, never the back! In general, the less material you remove, the better.
Can you remove burrs from augur bits?
The main cutter can also develop a burr during sharpening. Again, this can normally be got rid of by simply using the bit. But if not, it can be removed using a very fine stone. You must also be very careful not to cut a second bevel on the reverse side of the edge. Be absolutely confident about following these steps, before you tackle an augur bit.

Jennings and Irwin are different twist patterns. jennings was considered the better of the two.

Can you use a flat file for a hollow grind?
You can still use a flat or triangular file for this. The hollow grind is just a method used by Stanley, but by the very cutting edge there must be a flat anyway as all hollow grinds must be refined with a flat to form the angle.
