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

Drilling a hope in dry wall. Did the job very effectively. Only used it one so cannot comment on its durability

Edit: I was contacted by the seller after posting my original product review offering a refund if I “change my shopping experience”. Even with the offered refund I can only adjust this from one star to three stars due to thh HR e hassle and delay of having to acquire a replacement to finish my job. Original review follows: Bought this to drill holes in ceiling Sheetrock for led lights. First one went well, second one did good, third one got through with extra effort. Fourth one mostly got through but not quite. Tried it on the fifth one and it would barely scratch the surface. It’s done for, but I have ten more to drill! Don’t do it Ethyl! It’s just not worth it!

I had to cut a bunch of 6.1 inch holes into drop ceiling panels for canless LED lights. I tried to use a utility knife first... That was awful! This blade cut it nice and smooth. You need a bigger drill... It is large and you need to get the speed up before you dig in. Saved me a ton of time and frustration! Worth much more than the cost.

Bought this hole saw because I thought it would be the better option. Came with 3 bits. One bit was broken in the box upon receiving it. Not a big deal, there was 2 more. Attempted to use it on some sheet metal, wouldnt cut through it. The Allen screw to secure the drill but doesnt stay tight, just vibrates loose and falls out no matter how tight you make it. Also the locking mechanism fell apart so its no longer usable. I ended up getting done what I needed, it at least made a nice template in the sheet metal and I cut the rest out with a dremel.

Doesn’t work well on sheet metal, but did not get dull.

Parts missing, only got hole saw no center parts. No way to use it.

Used this for one project. Held up fine. Cant beat it for the price.

Just what I needed

I bought this to cut holes for recessed lights in my back porch ceiling that is 29 ga metal sheets. It makes and awful noise and wouldn’t even cut through the sheet metal. I ended up using tin snips by following the ring the saw made into the metal. Metal just gets hot from friction after you try cutting through it for a long period of time. it worked well with sheetrock ceiling though, but not really why I bought it.

Hole saw chucked and worked flawlessly. I don’t know how it will be long term but I made 4 sets of cornhole boards with 3/4 inch birch plywood and it cut through the last as clean as it cut through the first. Still very sharp and such in my opinion.
