Milwaukee 4-1/4-Inch Ice Hardened Hole Saw (49-56-0223) – Hole Dozer

Overview

Discover the Milwaukee 4-1/4-Inch Ice Hardened Hole Saw, a rugged 49-56-0223 model built for metal and wood cutting on demanding job sites. Crafted with a proprietary cryogenic hardening process, the core and teeth are designed to stay harder longer, aiming for extended use under tough conditions. Combined with Matrix II bi-metal teeth and an 8% cobalt alloy, this hole saw strives to deliver durable performance while maintaining hole quality across diverse materials.

In addition to cutting strength, Milwaukee enhances usability with thoughtful design touches. The hole Dozer features a plug Jack, an all-access slot arrangement that enables easier plug removal at varying material thicknesses. The tool is compatible with Milwaukee arbors for quick, tool-free changes, and it’s designed with a radiused tooth back and deeper chip gullets to reduce stress and clear chips efficiently. Built in the USA, this piece emphasizes durability and consistency you can rely on when the job heats up.
