in. Ice Hardened Hole Saw 49-56-0213
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 that is more consistently hard
throughout, resulting in life up to 50% longer than the competition.
