Product Overview

Use the Milwaukee 2-1/8 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.

  • 1/2 in. chuck size
  • High-speed steel construction
  • 2-1/8 in. Dia
  • 1-51/64 in. drilling depth

Arbor Included?

The details don't say one way or another so one would assume its just the hole saw and not the arbor to attach it to a drill, so does it come with the arbor at this price?
Asked by: Jumborabbit
No.

The hole saw did what it was designed for I bored 10 holes in 3\4 thick cast iron plates with only one hole saw I completed the job under the estimated time which equals profit They are good for those who know feeds and speed run them a slow rpm and they will last many jobs down the road

I purchased this exact size from Harbor freight in a 3 pack with variable sizes which is $10 less than this bit by itself. The generic bit made 5 recessed lighting holes with ease through lathe and plaster. I assumed if I spent a little more money it would get one that lasted longer and cut faster. I was completely wrong! This bit went dull after cutting two holes and I even pre-drilled the holes with the dull cheap bit to avoid the lathe from eating the teeth. I am sure this is good for cutting balsa wood at best.

I used this with a quick change center drill bit arbor from Milwaukee and this was an excellent hole saw through my roof for a new attic fan vent. Makita 18V LXT 1/2 drill in higher torque mode was sufficient to cut through without flaw or trouble, maintaining light pressure and letting the saw do the work. A heavier duty drill would have provided even more torque, and with a handle mounted I think this saw would have drilled through quite rapidly. Excellent quality, excellent performance.

Rated 5 out of 5 by from Does the job if you keep it cool I see a number of reviews criticize this saw because it dulled on them in both wood or metal. I too have ruined some of these hole saws in the past by not keeping them cool while sawing the hole. Use lots of oil or soapy water in a spray bottle to cool the teeth as you are drilling and the saw teeth will retain their temper and saw efficiently. This one worked great to cut a taillight hole in jeep CJ body armor .

Rated 2 out of 5 by from Not good for metal! I recently got this hole saw to cut two holes through some stainless steel sheet metal. And I must say that I am VERY disappointed in its performance. These bimetal hole saws are sold as being capable of cutting through metal (including stainless steel), but it looks like they are fundamentally a woodworking tool that just cuts metal as an afterthought. I specifically tried cutting the steel at as close to the recommended 80RPM as my drill would allow and used plenty of cutting fluid. But it was slow going all the way. And the tool ended up becoming uselessly dull in the end. And at $13 a pop, that's pretty expensive for a tool that is not going to last. Granted, if you are into woodworking rather than metalworking, this hole saw will probably serve you well. It might even be OKAY if you use it to cut aluminum. But it is clearly not meant for cutting steel (and should not be sold as such).
