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.

  • Bits mount to chucks with a minimum size of 3/8 in.
  • Bi-metal construction with 8% cobalt composition for increased wear resistance
  • Cryogenically treated for up to 50% longer life
  • Optimized tooth form for fast cutting
  • Wide, angled- and offset slots for easy plug access
  • Includes 3/4 in.-, 7/8 in.-, 1 in.-, 1-1/8 in.- and 1-1/2 in. hole-saw bits
  • Case included

Rated 3.1 out of 5 by 9 reviewers.
Rated 2 out of 5 For wood these are great, but for metal, you'll be frustrated and disappointed. I bought these bits to punch through a 16 gauge electrical panel. These things eventually ground their way through via friction. Took a Red Lithium Ion battery per hole, so 10-15 minutes worth of drilling and lots of cutting oil to keep it from over heating. So I was not very impressed with this at all for metal working. I'm going to buy the Greenlee set. The Lenox bits might be better too as I saw a demostration with a drill press that outlasted everything in it's class. I will have to give them a try. For wood these things are great, but not for metal. I might even buy a hydraulic knockout punch set. I really needed the ability to drill because I had to drill holes into 2 adjacent mounted electrical panels and run a nib through both of them. March 11, 2014
Rated 5 out of 5 by Filled a need for several projects This tool will enable me to complete several of the projects I have on my whiteboard. July 9, 2014
Rated 1 out of 5 by Quick release is a joke Bought this set because of the quick release feature. Quick release doesn't release saw from mandrel, in fact, saw is currently so stuck after one use I will be returning the kit. I'm not even sure what the release feature does it doesn't release the pilot bit either. January 14, 2014
Rated 2 out of 5 by Wobbles The arbor is not straight and wobbles terribly. It's a wild ride during use, and leaves you with a bigger hole than you wanted. The case is nice. The quick release mechanism is intuitive and works well. November 28, 2013
Rated 3 out of 5 by So-called quik-release cam mechanism poor Instructions non-existent. Attaching holes to cam was trial-and error. Finally attached 1.5-inch hole blade but quik release never worked. Forget the "quick". Otherwise, you can cut holes if you have a good drill. October 11, 2012
