The Milwaukee® SHOCKWAVE™ Impact Duty™ Thin Wall Hole Saw Kit (49-22-4800) is engineered for professional electricians and contractors who need fast, clean holes in plastic enclosures, junction boxes, and thin-gauge metals on the job site. Featuring a ¼" quick-change hex shank, this 3-piece kit pairs directly with impact drivers — no arbour swapping, no downtime. The thin wall, 8 TPI design cuts up to 40% faster than standard bi-metal hole saws and delivers burr-free results, while the built-in ejection spring automatically clears slugs so you stay focused on the work. A stop shoulder prevents over-drilling, protecting the inner components of electrical and junction boxes. Whether you're roughing in conduit knockouts, pulling wire through panels, or fitting fixtures on a commercial build, this kit keeps pace with the demands of the trade.
