Set of 14 Red Devil spur auger bits, coarse lead screws

Description

These spur auger bits are in well-above-average condition.  The largest — which I suspect was not part of the original set — has a layer of storage rust.  The spurs are quite sharp and there’s a lot of them left.   Will make great workers.

I suspect that these were actually made by Irwin, but there’s no way to be sure.
