For straight plugging operations, nothing works better in the 1/4" to 1/2" sizes than our carbon steel Snug Plug cutters (available separately), but for larger plugs or for cutting tenons, these are the best you can get. Not only are they made to very tight tolerances and will therefore cut accurate tenons and plugs, but we spent nearly two years in a design and test process to get the cleanest possible finish and the least heat build-up while cutting.
With carbide tips on the cutting spurs and rakers, they excel in hardwood or heavy use. The convenience of being able to cut tenons and plugs up to 3" in diameter makes these bits indispensable. Plugs 1" long or shorter automatically side eject. Total available depth of cut is 2". Cutters up to 1" in diameter have 1/2" round shanks, above 1", 1/2" hex.
For use only in a drill press.
Available individually and as a set of four (sizes 3/8", 1/2", 3/4", and 1") or as a boxed set of six (sizes 3/8", 1/2", 5/8", 3/4", 7/8" and 1").
