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. The Milwaukee 8-Piece Bi-Metal Hole Saw Kit features durable bits made with 8% cobalt and cryogenically treated for a long service life. A case is conveniently included for organization and transport.
