Accessibility Statement


A 1/2" or 8mm shank bit with four sizes of slotting cutters for grooving, dadoing, and tongue and groove joinery. Individual double-tipped cutters will produce 1/8", 5/32", 3/16" and 1/4" grooves and, when combined, will cut grooves from 1/4" to 23/32" wide.

In the tongue and groove configuration, the bit is suitable for wood between 9/16" and 7/8" thick. When used with the ball-bearing guide, the depth of cut is 1/2"; otherwise, when used with a fence, the bit will cut up to 5/8" deep. 1 7/8” in diameter.

Complete with spacers, shims, instructions and an advanced polymer friction-fit holder that can be mounted horizontally or upright.

This bit uses a 22mm × 8mm replacement bearing (available separately).
