Woodworker’s Supply offers CleanStop countersink bits

The CleanStop countersink bits, available from Woodworker's Supply, solve the problem of clogging and burning associated with traditional countersinks and stop collars, according to the distributor.

The bits, introduced in 2007, feature extended chip-ejecting flutes and SlipStop collars with "windows" that align with the countersink flutes for better chip ejection.

The bits are sold in a set of four sizes for No. 6, 8, 10 and 12 screws. Also included in the kit are one large and one small SlipStop collars, a hex wrench and a burl finished cased with a fitted interior.
