Made exactly to our specifications, these bits took over a year to develop and refine. The great advantage of high-speed steel (HSS) bits is that heat build-up will not soften them, as will happen with carbon steel. They are forstner pattern and have 3/8" round shanks.

The rim on the forstners is proud of the chippers by only 0.005" to 0.010", reducing rim heat. The bits have slightly sloped chipping bevels so that they ride a shallow cone of wood to keep them boring straight. Center brads can then be shorter, increasing bit versatility in thin material. As a last touch, bits have been finished with extra-fine grinding wheels to reduce friction.

The set of six includes bits from 5/16” to 15/16” in 1/8” increments. Overall length is 3 1/2".
