Milwaukee 48-13-5003 3 Piece Countersink Drill Bit Set

Product Description

The Milwaukee Electric Tool Corp 48-13-5003 is a 3-piece countersink drill bit set designed for pre-drilling and countersinking in a single pass. The set includes number 6, number 8, and number 10 countersink sizes, covering the most common fastener sizes used in woodworking and light fabrication. Each bit features a 1/4-inch quick-change hex shank for fast swaps between sizes without additional tooling. The drill bit depth is adjustable on each piece, giving installers precise control over countersink depth to match fastener head profiles. This set suits carpenters, millworkers, finish contractors, and trade professionals who regularly drive wood screws into trim, cabinetry, or structural framing.

This countersink set is suited for residential and light commercial applications where clean, flush fastener seating is required. Typical use cases include installing door hinges, cabinet hardware, trim work, decking, and subfloor fastening. The quick-change hex shank is compatible with standard 1/4-inch hex chuck drivers and impact-ready bit holders, making it practical for cordless drill and driver setups already in use on the job site.

Installation Notes

Installation is performed by carpenters, finish contractors, and general tradespeople using cordless drills or drivers with a 1/4-inch hex chuck or quick-change adapter.
