Milwaukee 3 Piece Shockwave Impact Duty Holesaw Set

The Milwaukee 3 Piece Shockwave Impact Duty Holesaw Set is a professional-grade cutting solution designed for clean, accurate holes in thin metal using an impact driver.

Built from 8% cobalt bi-metal construction, these holesaws are engineered to deliver exceptional durability and extended cutting life on demanding job sites. The 0.6mm thin wall design reduces resistance through the material, making them well suited for electricians, plumbers, and contractors working in sheet metal, electrical back boxes, and light fabrication applications.

The 1/4" hex shank provides direct compatibility with impact drivers, removing the need for an additional arbor and speeding up workflow on site. An 8 TPI tooth configuration produces smooth, burr-free holes, while the shallow cup geometry is specifically optimised for drilling thin metal. A built-in stop shoulder prevents over-drilling, and the integrated ejection spring automatically clears slugs from the cup — reducing interruptions and keeping the job moving.
