Milwaukee 49-22-4185 Ice Hardened Hole Saw Kit 28-Piece

Durable performance for metal and wood cuts

Meet the Milwaukee Ice Hardened Hole Saw Kit, a 28-piece collection designed to tackle HVAC, electrical, plumbing, and maintenance tasks with steadier performance. Built to handle harsh worksite conditions, this kit blends everyday reliability with long-lasting cutting power that can help you move through jobs without frequent tool changes.

The core advantage comes from a cryogenic hardening process that strengthens the teeth all the way through the bit. Unlike coatings that wear away, this cryogenic treatment hardens the cutting edge at the core, helping the kit resist wear during repeated cuts. Combined with Matrix II bi-metal teeth, the saws deliver robust durability and steady cutting action across a variety of materials.

Key design advantages that support faster, cleaner holes

• Cryogenic hardening strengthens the core for extended life and consistent performance
• Matrix II bi-metal teeth for increased durability under tough cutting conditions
• Positive rake angle for faster, more aggressive cutting
• Radiused back face reduces tooth stress to help maintain cutting speed
• Deeper gullets promote quick chip removal, minimizing clogging
• Functional slot geometry allows easy plug removal with a standard screwdriver
