This is a nice, clean heavy duty 10" long x 1.25" diameter brace auger bit. This is a double cutting edge, single spur auger bit for heavy duty work. It marked "CAR-VAN" on the shank and 20 on the square tapered end shaft (20/16) is the size. We note that the tapered end, the cutting edge and the threaded screw end are all in very good working order. We also note no rust, clean, and ready to use. Drills/cuts just fine.
