6 inch/152mm Hole Saw Heavy Duty Bi-Metal HSS Hole Saw for Cornhole Boards, Plywood, Iron Board, Acrylic, Ducts, Ceiling Lights, Cinder Wall

This is a decent but not great hole saw. What it really comes down to is how much and how often youre going to need to cut one of these large holes, because this one will work great for a while, but wears out relatively quickly (how quickly will depend, of course, on what youre cutting). If you have a specific project in mind or only need it for occasional use in a hobbyist workshop, its great. If youre going to need to cut these holes all the time, youd be better off investing in a saw with greater longevity.

Needed holes in car hood and it did the job a couple things to be aware of Didnt realize I needed a half inch chuck for this...probably in the description if so I didnt notice. Thankfully I had another smaller hole saw and used that smaller shaft set-up. I bought the 4.25 size and a cordless drill is not gonna have the power needed once you get into the metal... at least not a 12V. My old corded drill had no power issues and it worked great. If cutting steel, go slow and be careful, because when it goes through and catches and edge youll know it.

Built corn hole boards out of plexiglass, taped up area to drill . Went through with no problem

I have an entertainment console with a huge flat screen TV, and its full of audio and video components. The problem is that all of my network ethernet connections are behind it, and I needed to swap out an ethernet cable from the wall port to the router in the console. The console is too much to move, so I used this to cut a hole in the back, just near the ethernet ports behind it in the wall. Now I can reach through, disconnect the cable and plug in a new one without having to literally disassemble the entire console and its components. Great size for my needs (and the console already has holes in the back for cables and cooling anyway, so no biggie.)

Good

This hole saw really impressed me. I needed to cut a bathroom vent hole through aluminum siding and thick sheeting/wood. This saw did the job with no hesitation. The teeth still look very sharp and I would imagine I could cut many more holes as needed for other jobs. The arbor on this hole saw is thick, durable, and worth spending the few extra dollars on vs the others that only thread into the saw hole. This arbor has thick metal pins that hold the bit in place properly. I have a very nice Milwaukee assorted hole saw set but it didn’t have a size this big. The Milwaukee bit alone was 3X-4X the price of this setup which also included the arbor and 3 bits. I took a chance on this and I am glad I did, I highly recommend this.

Worked great for the what I needed it to drill a hole large enough to put 4 in PVC through plywood wall. Looks like it would be good for 10 to 15 penetrations which in my cut case is a lifetime. Came with extra centering drills and Allen keys. Cant be beat for the money you dont need $100 hole saw when youre only going to drill a few holes.

I used this hole saw for 120 mm case fans. It worked great

Arbor broke after one use

Sharp, well constructed and arrived quickly. Cant comment on how long it will remain sharp but feels well built and worked perfectly on arrival!
