Milwaukee 49-56-0082 Ice Hardened Hole Saw

Milwaukee ice hardened products utilize a proprietarycryogenic hardening process that improves upon traditional heat treatprocesses. Unlike surface coatings that wear away cryogenics Harden to thecore by minimizing soft metal (austenite) and creating more hard metal(martensite). the result is a product that is more consistently hardthroughout resulting in life up to 50% longer than the competition.
