Milwaukee 4-1/4-Inch Ice Hardened Hole Saw - Hole Dozer with Rip Guard

Premium performance for metal and wood cuts

Meet Milwaukee's 4-1/4-Inch Ice Hardened Hole Saw, a rugged choice designed for HVAC, electrical, plumbing, and maintenance tasks. Made in the USA, it uses a cryogenic hardening process that hardens the core, delivering up to 50% longer life than many competitors. The Matrix II bi-metal construction, reinforced with 8% cobalt, and a positive rake angle work together for fast, durable cutting with steady edge life. The tool’s deeper gullets quickly evacuate chips, while a radiused back reduces stress on the teeth to help maintain cutting performance through long jobs.

The Hole Dozer line includes thoughtful features such as functional slot geometry for easy plug removal and Plug Jack access that lets you reach deeper into cups or closer to the teeth, depending on material thickness. For quick, tool-free changes, Milwaukee offers universal arbors that pair with a range of compatible arbors to fit your setup. This combo is well suited for metal and wood work across a variety of trades, from on-site installations to shop projects.
