            Had to cut a stainless steel sink hole
            Well, I had to cut a hole and a stainless steel sink, it got the job done. Clean smooth hole, the teeth are gone off the bit. Only one use and it’s in the trash can..

              Doesn’t cut metal efficiently
              I needed to make a hole on the underside of a car to insert hardware to fasten a hitch attachment. This tool seemed like it could do the job going off the Milwaukee brand equity. It’s a crap product and wasn’t able to get through thin stew sheet metal. I ended up using small drill bits to perforate the metal along the grove this hole saw made before the teeth became totally flat. Don’t buy this to cut into thin sheet metal of a car because it won’t.

                Impact shank broke after 4 uses
                Electrical/HVAC contractor when seen this thought it’s was great idea for us in the field. Worked awesome first 3 jobs and on the 4 SNAP! Impact shank broke off 20 mines later fishing it out my impact stuck back and finished the job. Doesn’t lock anymore left right or up good. DOWN position forget. Awesome idea if it was better quality. Thanks

                  Most hole saws are acceptably sloppy things, given the nature of their job. But this saw's small kerf and teeth/inch left holes so smooth they look like they were cut by a forstner bit. Even in 5mm plywood, there wasn't any shredding or breaking of the top laminate. Wobbling was imperceptible. The shank is 1/4" but the pilot bit is not. Mine was 5/32" The ejection spring was helpful, but the plug still needs to be pried out. The disc it cuts out is 1.2" in diameter. Well-made, but on the expensive side for what it is.

                    Used on drill press on nema boxes. Made over 300 holes . Lasted longer than Klein 7/8 carbide tip and half the price .

                      Poor Quality
                      I attempted to use a right angle drill to cut through a metal stud. The stud is only about 1/16 or so thick. The pilot bit broke before I completed a single hole. It broke within 5 seconds of pulling it out of the package. Extremely disappointing!

                        wish it was a good tool
                        Pilot bit broke on first use. Easy enough to drill a hole with a regular bit and just shove the broken end through the hole. Saw portion works. I like the rim which keeps you from plunging your saw too deep in the new hole. I like the spring which ejects the freshly cut plug. Ill replace the pilot bit, but only once. If i break it again ill just buy something more reliable.

                          Poor Quality Control
                          These work great when they work but I have bought several that have had a variety of issues. Some come dull out of the box some have had the pilot bits fall apart. The one I am using now came brand new with a dull pilot bit. I spend a lot of tools in a year and have spent too much on shockwave hole saws that don't work. Luckily home depot has exchanged them for me several times.

                            I have my weber grilled hooked to a hose connected to my house propane. I decided to put the spare tank under the grill and away from the garage. But the tank hole was where my hose exited. I decided to drill a 1 inch hole in the side of the grill to run the hose and to not disrupt the tank placement. Wow. For such thin metal, it was next to impossible to get solid drill bits through the side. I started with small bits and increased. I went to HD to get a 1 inch solid bit but there were $30 ish. Then I found this and remembered how well they work on door handle holes. This bit is for metal. It drifted at first since I already had a 1/2 inch hole (my bad). But to drill through the grill took maybe 10 seconds. The blade is super sharp and well made. Great product. I touched up the side hole with two inch PVC to keep the edges of the metal away from the gas hose, then painted all with flat black paint. Works great.
