 |
Auger bit files are saw files. They are unusual in that they have two heads with a handle in the middle. | |||
 |
Auger bit files are used to sharpen a specific type of drill bit used in woodworking called (you guessed it!) an auger bit. | |||
 |
These drill bits work in a similar way to a cork screw and have a sharp edge that starts from the bottom of the bit and twists upwards. | |||
 |
They also have a section with a much tighter thread, almost like a screw, which helps the drill bit to stay on course. | |||
What are the characteristics of an auger bit file? |
||||
 |
Cross section and profileThe cross section of an auger bit file is thin and rectangular. Both heads are spear shaped, tapering in width towards the point. |
|||
 |
CutOne one head, just one of the faces is single cut. On the other head, both edges are cut. The rest of the file is safe. |
|||
 |
Auger bit files have specific segments that must be kept sharp. These areas are at awkward angles, and it is important that no other parts of the bit are accidentally filed down. | |||
 |
The taper of an auger bit file, along with its safe edges, allow DIYers to sharpen the bits without the worry of accidentally damaging their tool.
