- The Milwaukee Shockwave Impact Hole Saws are designed with a robust, impact rated 1/4"-Hex quick-change shank and give professionals a hole making solution to use with impact drivers. Utilizing a thin wall, 8TPI design, Shockwave Impact Hole Saws deliver a burr-free cut up to 40% faster than standard bi-metal hole saws. The included ejection spring removes the frustration of manually removing slugs by automatically ejecting the material. A stop shoulder design prevents over-drilling into material and potentially damaging inner components of electrical and junction boxes. Choose Impact Hole Saws for use in plastics and thin gauge metals up to 1/8? thick.
