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 comes with everything you need right in the box. Sometimes you have to spend more money on an arbor or center mount. This has all of that so you can just open, assemble, and get to work in a few minutes. It is a beast on the cut teeth. I purchased to use to install a 6 inch ducting system for a laser cutter exhaust. It cuts 152 mil which is 2 mil larger than the ducting I am using. Duct hose and fittings all fit perfectly with this size. You will get years of service from this.

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.

Make a clean hole.

Seems well built. Biggest issue is I did not receive the allen screw that is clearly shown in the pictures. Not a huge deal I can just go out and buy one - buts its annoying that I have to. Review Update. First time using it (in drywall - nothing tough) the drill bit snapped on the 5th hole. My opinion now is its garbage

I purchase this to make two cornhole boards. It did not make it through one hole. Dowel pins snapped off the top then had to welded it together. Then top hex bolt Snapp next

This 6-inch hole saw came with two extra drill bits. The hole saw is thick steel at the base and is machined well. The hole saw arbor(shaft) is stout, the arbor shaft is a big 1/2 inch (the normal ones are 1/4 inch shaft) so make sure you have a drill that will fit it. The abor fit well on to the saw and drive pins lined up easily. The saw cut a pretty clean hole with not a lot of splintering. (The pictures are no clean-up or finishing) It made a pretty exact 6 inch hole (that is the size hole for corn hole boards) The only issue is that the saw teeth dont seem very sharp. (It went through the wood without an issue)

Arbor broke after one use

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.

Used this to cut holes in our mini golf course. It worked well once we figured out the assembly - not as straight forward as other hole saws / bits. Take it slow and let the blade do its job otherwise it may fight back. Went through plywood boards and supporting 2x4s. Not sure on longevity, but it did the intended task quite well.
