Set of 3 Solid Carbide Spiral - While specifically designed for the Leigh Isoloc templates, this 3 piece set up spiral upcut bits is an ideal set of straight cutters for any application. Spiral cutters cut cleaner than traditional straight cutters, with the upcut action designed to clear the waste out of a mortice or joint.
Includes 1/4" (6.35mm), 5/16"(7.9mm) and 3/8"(9.5mm) bits.
A reducer from 1/2" to 3/8" will be needed.
