Use the Milwaukee 3-1/2 in. Bi-Metal Hole Saw to cut holes in a variety of materials. The steel hole saw can drill almost 2 in. deep. 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.

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

Rated 5.0 out of 5.0 by Works Like A Champ Need to cut a perfect circle? Nab one of these. I used it to cut a hole in our front siding for an exterior light. Made the job easy. Home Improvement 101- get one of these. You may not need them on a daily basis but when you do, can't beat it. March 18, 2014
Rated 3.0 out of 5.0 by Works great on everything but Stainless Steel We tried these not stainless steel and they did not last at all, on the other materials that we have here they worked well. September 2, 2014
Rated 4.0 out of 5.0 by very happy to have i really liked how easy it was to put it together and i was able to drill thur the roof in just a few minutes. i was also able to drill a few more holes that i didnt think was going to be able. August 6, 2014
Rated 1.0 out of 5.0 by No way! This was terrible would barely saw through 1/2 inch ply. I was using this as a replacement to a previous brand that I had, which was great! I got it from a different store though. Very unsatisfied as I thought Milwaukee was a great brand. The hole saw is already worn down after only barely cutting one hole! Pathetic please go with another brand I am sure any other brand is better than this! Waste of like $18 with tax ugh! Before anyone chides me on not using it properly I have cut about a dozen holes with a different brand with no issue prior to this. June 2, 2014
Rated 2.0 out of 5.0 by Not as good as lenox Lenox hole saws last longer and stay sharper longer, only purchased because Lowe's was not close. I buy most things at Home depot, except hole saws. June 3, 2014
