Milwaukee, 49-56-0122, 2-1/16 in. Ice Hardened™ Hole Saw

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 percent longer than the competition.

Features:

•Ice Hardened cryogenically treated for up to 50 percent longer life
•Optimized tooth form for up to 2 times faster cutting
•Wide, angled and offset slots for easy plug access
•Bi-metal construction with 8 percent cobalt for increased wear resistance
