Dewalt DW2539 Countersink Replacement Drill Bit No 10

Product Description

The DEWALT DW2539 is a No. 10 countersink replacement drill bit designed for screw driving applications. Measuring 3/16 inches in diameter, this replacement bit integrates into a countersink system to create flush or recessed pilot holes for No. 10 screws. It is used by carpenters, finish tradespeople, and general contractors who require clean, consistent countersink results in wood and wood-composite materials. The bit is sold individually as a direct replacement component within compatible DEWALT countersink sets.

This replacement drill bit is suited for residential and light commercial finish carpentry, cabinetry, decking, and trim work where countersunk fasteners are standard practice. It allows the drill bit portion of a countersink assembly to be replaced independently, extending the life of the full countersink unit without requiring full-set replacement. Typical use involves wood substrates where screw heads must sit flush or below the surface.

• No. 10 sizing for use with No. 10 wood screws
