Set of 13 Imperial HSS Forstner Bits with Wooden Box

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. Bits larger than 1" in diameter have 1/2" hex shanks. Bits up to 1" in diameter are forstner pattern and have 3/8" round shanks.
