Quantity:
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, bits have been finished with extra-fine grinding wheels to reduce friction.
Overall length is 5" for bits from 1 1/16" to 2", and 6 1/2" for bits over 2". All have 1/2" hex shanks.
