Product Details - Drilling - Specialty Drilling Bits - Tapered Snug Plug Cutters

Unlike regular plug cutters, they also shave the plug sides as they cut, producing very smooth plugs. You just tap a plug into a hole until you meet resistance, then cut off the excess. You will then have a plug that fits perfectly, with a nearly invisible line between the plug and the workpiece.

These plug cutters are carefully reamed after hardening to ensure perfect concentricity. It is difficult to believe how nice a plugging job you can do until you actually use one. 3/8" shanks. Patented. Resharpening instructions included.
