SHOCKWAVE™ Impact Duty 8-32 UNC Drill and Tap Bit

Speed up your metal fabrication and electrical installations with the Milwaukee® SHOCKWAVE™ 8-32 UNC Impact Drill Tap. Engineered for high productivity, this multi-purpose accessory drills, taps, and deburrs/countersinks in a single pass—eliminating the need to switch between drill bits and dedicated hand taps. Rated for use in metals up to 1/4" thick, it cleanly cuts standard 32 threads-per-inch threads into mild steel, sheet metal, and junction boxes. Built with a heavy-duty 1/4" quick-change hex shank, it is engineered to withstand the rigorous pulse torque of cordless impact drivers while maintaining compatibility with standard drill drivers. Finished with permanent laser-etched markings for instant size identification in crowded bit cases.

Key Features:

• Simultaneous Drill, Tap & Countersink: Completes pilot hole drilling, thread cutting, and edge chamfering in a single continuous step.

• Standard 8-32 UNC Threading: Cuts clean, precision-pitched 32 TPI threads ideal for electrical fixtures, conduit mounts, and mechanical assemblies.

• 1/4" Metal Capacity: Engineered to bore and thread reliably through steel plates and sheet metal up to 1/4" thick.

• 1/4" Quick-Change Hex Shank: Delivers maximum power transfer and rapid bit swaps in impact drivers and standard drill chucks.

• Built for Impact Duty: Optimized geometry and metallurgy withstand aggressive torque loads without binding or snapping.

• Integrated Countersink Shoulder: Chamfers the entry hole upon completion to deburr sharp edges and seat fasteners cleanly.

• High-Contrast Laser Etching: Size markings are laser-etched into the body for permanent, easy tool-pouch identification.
