These Scotch (no spurs- two cutters) augers have the Jennings pattern double twist for hand operation.
An auger handle is placed through the eye of the auger and turned by hand to bore into the wood. The handle is not supplied. This is an effective means of boring a wide range of holes in hardwoods in a variety of locations, expecially where electric power is not available.
