he Diablo Forstner Drill Bit with a 1-1/4" 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 bit features a double-ground serrated edge for less splintering and chipping. The ultra-sharp spur ensures accurate hole placement and prevents the bit from walking on the material.
