Milwaukee 49-22-4185 Ice Hardened Hole Saw Kit – 28-Piece, All Purpose

All-Purpose Milwaukee Ice Hardened Hole Saw Kit

Meet the Milwaukee 49-22-4185, a 28-piece hole saw kit designed for versatile cutting across metal and wood. This set blends durable Matrix II bi-metal teeth with a cryogenic hardening process, delivering steady performance in HVAC, electrical, plumbing, and maintenance tasks without missing a beat.

Why ice hardened gives you an edge

The ice hardened core is engineered through a proprietary cryogenic process that hardens deeper than surface coatings, reducing soft metal and increasing wear resistance. The result is more consistent edge performance and longer life when cutting through tougher materials.

• Up to 50% longer life than the competition
• Matrix II Bi-Metal Teeth for enhanced durability
• Positive rake angle for fast, aggressive cutting
• Radiused back face lowers tooth stress during heavy cuts
• Deeper gullets for rapid chip removal
• Functional slot geometry enables easy plug removal

These design features work together to help you complete precise holes with fewer passes, cleaner edges, and less tool wear over time. The kit is structured to support both professional workloads and workshop projects where dependable performance matters.
