Milwaukee® Ice Hardened products utilize a proprietary crygenic hardening process that improves upon traditional heat treated processes. Unlike surfacecoatings that wear away, crogenics harden to the core by minimizing soft metal (austinite) and creating more hard metal (martensite). The result is a product that is more consistantly hard throughout, resulting in life up to 50% longer than the competition. Kit includes: six  (6) hole saws: 7/8", 1-1/8", 1-3/8", 1-3/4", 2", 2-1/2"; two arbors: 49-56-7010, 49-56-9100; 2 drill bits: 49-56-8010; one adapter: 49-56-6560; one spacer: 49-67-0120 and space for additional hole saws.
