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

  • 1-51/64 in. drilling depth

Trying to drill the exhaust hole for the dryer. Can I used this to drill through brick? its an old chicago building?

No. Use a masonry hole saw for something like this. Would probably be diamond-tipped.

2-1/8 in. Bi-Metal Hole Saw is rated 4.2 out of 5 by 504.

I bought the 4" hole saw in order to install nine, 4 inch round ceiling electrical boxes. The ceiling is 1/2" gypsum blue board with a veneer plaster sand swirl finish skim coat. The first three holes went fine, but I noticed the teeth were dulling at an alarming rate. By the time I got to the seventh hole, the teeth had completely worn away, and I had to "cut" new teeth into it using a Dremel tool and a an small stone. I realize that this hole saw is only meant for wood and steel, and I'm sure that the 1/8" veneer plaster is what dulled it, (once it got through the veneer plaster it cut like butter) but I was surprised at how quickly the teeth wore away considering that it was dulled by the fourth hole.

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.

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

Two things stand out: it is easier to get the cut material out of the inside of the saw after you finish the hole, and, it has double sets of mandrel centering holes, so any mandrel will sit as close as possible to the base of the saw. While this doesn't sound like a big deal, the less the saw vibrates, the better and truer the holes will turn out. Good, FAST removal of material, great choice for those that use cordless Drill motors. Well worth the price!

I bought this hole saw to make a neat hole in a plywood sheet that I was installing between tow plastic shelves that Home Depot sells. It's just the right diameter to let the plastic legs of the shelves fit thru. Used my cordless DeWalt drill and the hole saw did an excellent job of cutting thru the layers of the plywood. it has side holes so you can stick a screwdriver in to pry out the slug after you have made the cut.
