There is no file more versatile than this one. With safe edges and a cut face on one end and the reverse on the other, it is useful for much more than auger bits. It is ideal for brad-point drills, multi-spurs, shell augers, and any fine work where you want controlled cutting of only one surface.
You can work in restricted openings without causing accidental damage (as you would with a file cut on all surfaces). If you could have only two files in the shop, this one and a good mill file would be your top choices. 7" long.
