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. These are true saw tooth bits, not forstner bits with rim notches. The teeth have a skewed shear-cut design to prevent fiber pull and to give clean holes.
They have slightly sloped chipping bevels so that bits 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, the bits have been finished with extra-fine grinding wheels to reduce friction.
Shank diameter is 1/2".
