The Diablo Forstner Drill Bit with a 5/8" diameter and round shank is designed for precision drilling in wood. This high-speed steel bit is ideal for creating clean, flat-bottom holes, pocket holes, and overlapping holes without splintering. The sharp center spur ensures accurate hole placement and prevents the bit from walking on the material. The bit also features a double-ground, serrated edge for less splintering and chipping.
