Product Overview

  • Rip Guard, the strongest tooth form in the industry
  • 8% cobalt construction for increased wear resistance
  • Plug Jack, an all access slot design for fast plug removal
Use the Milwaukee 4 in. Bi-Metal Hole Saw to cut holes in a variety of materials. The steel hole saw can drill almost 2 in. D. 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 (Marten site). 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
  • 4 in. Dia
  • 1-51/64 in. drilling depth

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

4 in. Bi-Metal Hole Saw is rated 4.2 out of 5 by 655.

But if you don't have a drill press or a very heavy duty hand drill and the ability to put your piece of work in a vice, be prepared to take a small beating. This hole saw will "catch" and want to twist your arm off. A small drill will simply not take the punishment if you have multiple holes to drill (I was making a wine rake in red oak and had 15 holes to drill). Worked great in my drill press or when I used my heavy duty hammer drill and vice in non-hammer mode. When I tried to use my regular DeWalt electric (corded) drill, it liked to beat me to death. And I was only drill partial holes.

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

Rated 5 out of 5 by from Simply put, this is one tough, well made hole saw.... Simply put, this is one tough, well made hole saw. 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!

Bought this to run wires in our new built-in cabinets. This hole saw worked great with my cordless drill to allow me to route the various power and signal wires to the shelves / cabinets below where all the different components sit. The 2" cable sleeves (also bought at HD) fit right in and give a clean appearance on top where the TV sits.

Worth every penny of the painstaking process of trying to use a keyhole saw for installing recessed lighting and other tasks. Just be careful when using it. That's because it covers quite a bit of surface area, the torque kick back from the drill can surprise you. Just keep a stiff firm grip and arm at all time while using it to prevent injuries.

Bought this to cut through 1/2" OSB and 1/4" Hardiboard siding for a portable AC hoses. It did not cut well at all and took forever at varying speeds to even score the material enough to get a handsaw into to finish the work. This saw may work well in drywall, but it did not cut though the materials I had to get through & I will be returning it today.

Rated 2 out of 5 by from Purchased this hole saw to install a bathroom fan duct.... Purchased this hole saw to install a bathroom fan duct. I hit a couple of nails while drilling the hole, and the blades dulled quickly. Had to struggle to complete the hole, and was only drilling through two 3/4" layers of pine. Additionally, the HD price is quite high......can be found online much cheaper. I paid the price because I needed it.
