Forstner Bit

These forstner bits are made from a special grade of high carbon steel which is extremely hard wearing and retains its hardness over prolonged use, resulting in a bit that will not deform under heat and which will always keep the same cutting geometry, over its lifetime. The rim of the forstner bit is a fraction of a millimetre higher than the chippers which results in the bit entering the wood cleanly, prior to the chippers clearing the wood. The double-chip channels means swarf is quickly cleared, minimising rim heat, allowing for clean cut, flat bottom holes in hard, soft and exotic woods. The teeth have a skewed geometry to ensure minimal fibre pull and tearing of the wood.

The bits are back tapered from the cutting edge to reduce friction and prevent binding and have been fully ground to give precise concentricity to ensure a highly accurate hole. These bits are primarily used in a drill press or the tailstock of a lathe when boring end grain. The overall lengths of the bits are 90mm, with 10mm round shanks and available in 1mm increments from 8mm to 50mm. Our choice in forstner bits for the discerning woodworker and woodturner. ©
