Designed with a robust ¼” quick change hex shank, Milwaukee® Shockwave Impact Duty™ Thin Wall Hole Saws give professionals a hole making solution to use with impact drivers. Utilizing a thin wall, 8 TPI design, Thin Wall 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 Thin Wall Hole Saws for use in plastics and thin gauge metals up to 1/8” thick.
