Highlights:

• Ice hardened hole saws are up to 50% more durable than heat-treated hole saws
• Great tooth geometry cuts twice as fast
• Wide, angled and offset slots make plugs easy to access
• Bi-metal construction (w/8% cobalt) for increased longevity

Leave it to Milwaukee to develop the next big thing in hole-cutting. The 49-22-4025 is a General Purpose Ice Hardened Hole Saw Kit which contains 9 great hole saws, 2 arbors, and 2 pilot bits. If you haven't heard of Ice Hardened technology, it utilizes a proprietary cryogenic hardening process that is up to 50% more effective than heat-treating. That's not the only improvement Milwaukee made, the optimized tooth form leads to 2x faster cutting speeds. Its bi-metal construction also features 8% cobalt to make each hole saw last longer. Plugs are much easier to access as well with the wide, angled, & offset slots. Be the envy of your co-workers with this stellar hole saw kit from Milwaukee.
