Milwaukee Ice-Hardened products utilize a proprietary cryogenic hardening process that improves upon traditional heat treat processes. Unlike surface coatings that wear away, cryogenics harden to the core by minimizing soft metal (austenite) and creating more hard metal (martensite). The result is a product like the 49-22-4145 10-Piece Plumber's Hole Saw Kit that is more consistently hard throughout, resulting in life up to 50% longer than the competition.
