Milwaukee 49-56-0043 1 in. Ice Hardened Bi-Metal Hole Saw
The Milwaukee 49-56-0043 1 in. Ice Hardened Bi-Metal Hole Saw utilizes 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.
Features
- Ice Hardened: cryogenically treated for up to 50% longer life
- Optimized tooth form for up to 2X faster cutting
- Wide, angled & offset slots for easy plug access
- Bi-metal construction with 8% cobalt for increased wear resistance
- Works with the following arbors: 49-56-7240, 49-56-7250, 49-56-9100, 49-56-7055, 49-56-7040, 49-56-7140 & 49-56-7150
