Milwaukee 49-22-4800 Hole Saw Kit, Steel Cutting Edge

Designed with a robust 1/4 in 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 in thick.
