Dewalt DW2538 Countersink Replacement Drill Bit

Product Description

The DEWALT DW2538 is a Number 8 countersink replacement drill bit sized at 11/64 inches, designed for screw driving applications in wood and composite materials. This bit is a direct replacement component for compatible DEWALT countersink sets, restoring the cutting function of a worn or damaged pilot bit without replacing the full assembly. It is used by carpenters, finish trim crews, cabinet installers, and general contractors who rely on countersink sets for flush or recessed fastener installation. The 11/64-inch diameter is sized to pair with Number 8 fasteners, the most common size in cabinetry and trim work.

This replacement drill bit fits into countersink bit assemblies used in residential and light commercial carpentry. Typical applications include cabinet installation, deck construction, shelving assembly, and finish trim work where Number 8 screws are the standard fastener. Having a dedicated replacement bit on hand reduces downtime when a pilot bit dulls mid-job, allowing the countersink body to remain in service. It is sold individually, making it a practical stock item for crews that run high fastener volume.

Key Features

• Sized for Number 8 screws at 11/64 inches diameter
• Direct replacement for the pilot drill bit in compatible DEWALT countersink assemblies
• Sold individually for cost-effective restocking
• Compatible with standard countersink bit set bodies used in wood and composite materials

Compatibility

Designed as an OEM-style replacement drill bit for DEWALT Number 8 countersink bit assemblies. Consult your countersink set documentation to confirm pilot bit sizing before ordering.

Installation Notes

Installation of this replacement bit is typically performed by carpenters or woodworking tradespeople. Ensure the countersink body is removed from the drill and secured before swapping the pilot bit. Use the appropriate hex key or set screw tool specified for your countersink assembly to release and seat the bit. Do not overtighten the retention screw, as this can damage the shank or set screw threads.
