FOR USE IN A DRILL PRESS ONLY!
The countersink bits are used in conjunction with the 60 degree Industrial & Commercial Series Tenon cutters, NOT with the radius shoulder Home & Pro Series. They flare out the mortise hole to match the 60 degree taper to create a stronger joint and a refined look.
This multi-functional bit allows for interchangeable bushings to be attached, accommodating different size cutters. With this standardized design, without any bushings, fits a 1" tenon. Simply adding the appropriate size bushing will match the tenon size.
The CSK1000 kit works with the 1", 1 1/2" and 2" tenon cutters
