13pc ICE HOLE SAW KIT

The Milwaukee 49-22-4025 13-Piece General Purpose Ice Hardened Hole Saw Kit utilizes a proprietary cryogenic hardening process that improves upon traditional heat treat processes. The Milwaukee 49-22-4025 features surface coatings that will not wear away as the cryogenics harden to the core by minimizing soft metal (austenite) and creating more hard metal (martensite). The result is a hole saw that is more consistently hard throughout, resulting in a lifespan of up to 50 percent longer than the competition.
