49-22-4175 Milwaukee ICE HARDENED Hole Saw Kits

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 percent longer than the competition.15 piece set includes: eleven hole saws 3/4", 7/8", 1", 1-1/8", 1-3/8", 1-1/2", 1-3/4", 2", 2-1/8", 2-1/4",2-1/2", two arbors, two drill bits, one adapter, one spacer, plus a sturdy case with space for additional hole saws
