The diameter of auger bits for hand braces is commonly expressed by a single number, indicating the size in 16ths of an inch.

This is very important in chairmaking, due to the fact every one of the angles are usually eyeballed. A different benefit is they don't have a lead screw, so they can be drilled correctly in a very chair leg without having getting the direct screw peek out the opposite facet.
