Did not come with drill bit and spring assembly as advertised

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.

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.

This create a very precise hole for air ductwork. The metal is thick, preventing any warping of the shape. As usual with these painted hole saws, the blades are not very sharp. The emphasis is instead on keeping a uniform circle. I had another brand that looked identical and works the same way, but this is cheaper and includes the same features to avoid the chip getting stuck inside. I think it is a good value.

Awesome quality

drive bit broke on first use... event when using a replacement but the tiny screw that puts pressure to the drive but strips and continues to loosen...

I like to make (and would like to sell) wind chimes. The top piece is cut from cedar boards and this old boy has a hard time making perfect circles with a jig saw or a scroll saw. This is the perfect size and Ill be making perfect circles as soon as I get back from the lumber yard. Very heavy, thick steel. Should last a long time and make my fun a lot easier.

I loved the easy way the hole saw cut through my roof and ceiling. This was the exact size I needed to install my gas stove pipe through the roof. Fantastic price and worked great!

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

Just what I needed for my cup holders though I wish the well was a little deeper as I had to cut from both sides to get through a 2x4
