49618 Speedbor Brad Point Drill Bit, 1/2 In. Dia, 5-15/16 In. Oal

The Irwin 49618 Speedbor Brad Point Drill Bit is a precision wood drill bit designed for woodworking, furniture making, cabinetry, and doweling applications where exact hole sizing and clean results are essential. The brad point tip allows you to start each hole with confidence and accuracy, centering the bit precisely on your workpiece before the flutes engage.

This drill bit solves the common problems of splintering, rough hole edges, and imprecise sizing that occur with standard twist bits. The spur cutting edges and wide flute geometry work together to reduce splintering, ensure smooth and clean holes, and provide fast, continuous chip removal so the bit operates without clogging.
