ASTP&FH 2-3/4 Hole Saw with Arbor Mandrel ,HSS Bi-Metal & Heavy Duty Steel Design, for Metal,Stainless Steel,Cornhole Boards,Drywall,Plastic,Brass,Aluminum,Iron and Wood（70 mm）

It was inexpensive and thought Id try it to cut some holes through my Husky tool box for some pc fans... and it worked! I was skeptical but it did work. 2 holes total and teeth still feel sharp, they may have dulled slightly but Im sure it could cut another.

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.

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.

I make many winter feral cat shelters. Making the door has always been a bit of a hassle. I’ve always used a small reciprocating saw. Now I’m using this 6-inch hole saw and it cuts through like butter! Just made my life a lot easier. Works great. I hope this was helpful.

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

It got the job done, but had to back off on my drill press several time because it would stop spinning. Had to go lightly and take it slow. Seemed dull.

I bought this specifically for one job...I need one clean hole in my flat sheetmetal dashboard for my new speedometer. Says right there that it is suited for sheetmetal. it is, it turned out, suitable to score the steel, and to heat it up, and to warp it and to turn it into trash. Oh, I was patient and I kept the surface oiled but...

Precision, durable, efficient. Great tool.

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 used this hole saw on some shelves that I need a hole in for power cords to run through. It worked great. Cut through the plywood with no issues and left a nice clean hole.
