HOLE DOZER™ Bi-Metal Hole Saw Kit - 20PC

Product Overview

The Milwaukee 49‑22‑4170 HOLE DOZER™ Hole Saw Kit is a professional‑grade 70‑piece bi‑metal hole saw set engineered for a broad spectrum of drilling and hole‑cutting applications in construction, electrical, plumbing, and HVAC work. This comprehensive kit includes a wide range of hole saw sizes, arbors, and pilot bits to handle materials like metal, wood, plastic, drywall, and non‑ferrous metals.

Milwaukee’s RIP GUARD™ reinforced tooth technology places additional steel behind each cutting edge, increasing bit strength and reducing breakage when cutting metal or other tough materials. ALL‑ACCESS SLOTS in the hole saw bodies enable easier removal of plugs and better pilot bit visibility, improving workflow and cutting speed. A low‑friction Thermoset coating reduces drag, enhancing cutting performance — especially when using cordless drills.
