About This Product

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.

          Junk!
          Bought this to cut holes for recessed lights on a plaster with wood strip ceiling without wire mesh. After 2 holes, the blade was already dull!

            Very durable, long lasting hole saw. I have owned many sizes of this brand over the years. No need to look any further. The price is great for the excellent quality.

            one hole is all you get.
            I bought this hole saw to cut a hole in a piece of 1/4" mild steel. Milwaukee says it works on "thin/think metals" and the packaging showed a hole in an ibeam so i figured it would handle the task. i was able to (barely) get one hole done and it barely removed the paint on the second piece.

              6” hole saw junk!
              Cut 1 hole in drywall and the teeth have already rounded off. Wouldn’t even start the second hole. This bit is junk.

                    Works great easy clean out and I use daily I like the Dozer better than my other go to because they hold up longer. Next up will be the pa kout set with the case I like easy.

                      Heavy Duty and cuts smoothly
                      I use the hole saw to cut holes into the firewall on custom cars and trucks. Works great! And they last allot longer.

                        I would recommend this product
                        I am a plumber who needs holes fast, time is money. Product came fast, Looked great, and preformed even better. I put the dozer to work right away on some 10 gauge sheet metal and it made quick work of it. Love them!!

                          These are great. Of course Milwaukee products always are. They cut through fast and clean.
