It is what it said it was.

I got the 6” version specifically for cutting holes on ceiling drywall for mounting LED downlights. It did the job, but I didn’t use the arbor that came with the saw. As far as I can tell visually, this hole saw is made by welding an 18-gauge steel saw blade onto a ¼”-thick circular back plate (see attached photo). A thick back plate provides needed rigidity, but ¼” steel is a bit too thick in my opinion; it makes the hole saw noticeably heavy. This hole saw includes an arbor that didn’t work very well. I have other hole saws made by Starrett and Milwaukee. Arbors made by those companies have a threaded center with two protruding tabs, one on each side of center. The tabs are what drive the hole saw. The arbor included with this hole saw doesn’t have tabs (see attached photo). To install, you simply screw the arbor into the saw. As the hole saw is being used, the arbor tightens against the saw continuously. This makes arbor removal extremely difficult when finished. The Starett and Milwaukee arbors don’t have this problem. For cutting drywall, I like to start the hole saw backwards to prevent drywall tearing. Running the saw backward is not possible using the included arbor because the arbor will just unscrew from the hole saw. Fortunately, both the Starrett and Milwaukee arbor can be mounted and used on this hole saw without problems. Although this hole saw doesn’t look like it’s made from the highest quality material or using the best workmanship, I think it’s more than adequate for occasional non-professional use. It certainly does what I got it for. I just don’t use the arbor included with the saw.

Checked set screw before using was very tight,backed out very easily the first minute going through a 2” x 10” ridge plate was a bit unhappy.Stayed relatively sharp.

I purchased this hole saw to install 4 pod lights in plywood sofit. It did a nice job and the cuts were clean. I would definitely purchase this again.

There is another review on here that provides a good evaluation on this hole saw. (Well done, pmoy!) So I am not going to go very deep on this one. I am just going to say that for DIY or non-professional use, this is a good cheaper option to go with. I used it on drywall and had no problems. Satisfied.

Good product for the money. Needs holes on the bottom to easily remove stuck wood

My wife decided she wanted recessed lighting in the kitchen at our cottage. That involved cutting out the ceiling. I decided to try and make the job easier by looking for a hole saw to cut the holes. After searching a bit, I found this one by ASTP & FH. This hole saw did a decent job cutting out the 4-1/2” holes in the ceiling I needed to install my LED lights. The edges were a lot cleaner than I could have possibly done with my coping saw. And cutting them was fast….I had a perfect hole in all of 30 seconds. My only complaint about this hole saw is the fact there is a lot of play in the saw when it’s seated on the bit. It wobbles noticeably if it’s not pressed down on a board or, in my case, the ceiling. When pressure is applied to it, it’s fine though. The quality of the steel used in this saw is fair at best. And the shank could use a better fastener. But all in all, it worked, and my lights are up. This hole saw is great for an occasional job, but I don’t think it would hold up for repeated use.

Did not come with drill bit and spring assembly as advertised

Did what I wanted but struggled to cut threw a relatively thin piece of metal.

Nothing really wrong but one note of interest. In my application I was cutting 3/4 T&G knotty pine ceiling. the planks were 5 1/4 wide, so this saw was always going to hit a seam. When these teeth hit the seam they would grab, unless you ran the drill at a high RPM. then at a high RPM you could not control the saw once it breaks through. It caused some scratching on the surface of the paneling. After 4 or 5 holes I found techniques as to how to do it best. This may have just been my application of the hole saw.
