Yonico Forstner 20 mm Dia 10 mm Shank Solid Hardened Steel Forstner Bit

This carbide forstner bit has a 20 mm cutting diameter and a 10 mm shank compatible with all standard drill and drill press chucks. Forstner bits are a great choice for cutting clean and accurate flat bottom holes. Except for the slight notch created from the center spur, the resulting holes are clean and smooth. The middle spur helps center the bit, while the outer rim helps maintain the bits position when drilling angled or overlapping holes. Carbide blades add longevity to the bits life, making it a good choice for production shops.
