The Milwaukee 4-1/2 in. Hole Dozer Hole Saw features Rip Guard teeth that were built with more steel behind the cutting edge for added strength.

Answer: 
Yes, the Hole Dozer can cut through thick steel, even I-beams. For thick steel low RPM with generous cutting fluid/wax is recommended.

I have a Makita hole saw set, and actually used the adapter from that set, so it worked out perfectly.

Hi Geo, here is a list of the Milwaukee quick arbors that work with this hole saw.
Just make sure you match up the arbor that works with your drill chuck size.
For fast, tool-free change-outs, use Milwaukee's universal Quick-Change Arbors. 49-56-7210, 49-56-7240, 49-56-7250 and 49-56-9100.

4-1/2 in. Hole Dozer Hole Saw is rated 4.2 out of 5 by 294.
Rated 5 out of 5 by from Awsome tool I needed to cut a hole in a steel "I" beam. Amazingly, it cut through it with no trouble.

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 1 out of 5 by from Product Description Inaccurate The product description for this hole saw indicates that the Milwaukee arbor item number 49-56-7250 will fit this hole saw, which I made sure of before I bought because that is the arbor I have. However, it does not fit. If you look at the product description for the arbor, it indicates it is only for 1 1/4" and larger hole saws. Milwaukee and/or Home Depot need to get it together and make sure all products that are indicated to be compatible do in fact work together.

Rated 3 out of 5 by from Doesn't cut through metal I bought this to cut through a 20ga steel sheet for an enclosure, but it didn't work at all. Had to buy a step drill to get the job done. Also tried this on thin stucco. It got through, but the bit was completely burnt out doing so. The packaging didn't say you could use for stucco, but I thought I would mention it in case anyone was wondering how it would perform. Don't recommend this product for metal or stucco use. This did work great with wood.

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 .

I have only used this hole saw to drill through maybe 5 2x4 plates and it seems to be doing ok. Not so for the 4" size I bought a several months ago; it was dull after cutting through a single pine rim joist. Not what I would expect from Milwaukee! I'm not a fan of yellow tools, but the dewalt hole saw I replaced it with was deeper and is holding up well.

Rated 1 out of 5 by from Lasted less than a week Bought to cut holes in thin metal this tool only made 6 holes before being completely rounded out and unusable. The only thing worse than this product was the terrible customer service. Do yourself a favor a buy a nicer tool. I will not be buying another Milwaukee tool because of the poor quality and horrendous customer service.

Rated 1 out of 5 by from poor performance, drilled one hole in sheet metal and blade is dull when drilling the sheet metal which was only .032" thick the center bit wobbled and the hole drill started to orbit, had to exert a lot of pressure to cut. When the hole was finished the hole drill was completely dull and the drilled hole was undersized. Had to use half round files to finish hole.
