2-1/2 inch Hole Saw for Wood, Metal, Plastic & Drywall, with Arbor

I'm currently planning to add a dual hose portable AC unit with inverter to my garage, problem is the home was built in the 19th century and the garage is not the "typical" build. It's block with a wood roof and wood faces on the front and rear - I was planning to go straight through the wood wall at the top for the hoses. That's how I landed on this saw, as expected packaging was plain, but it did include a spare bit. Last night I decided to install my first vent in preparation, so chucked this up in a Metabo 18v hammer drill/driver - as others mentioned make sure you throw on your handle before using. Not thinking I tapped the trigger after chucking it, and it set off the RFC (anti-kickback) because of the weight of this thing, I felt my wrist begin to twist then remembered to put on the handle. With the handle installed I had no problem controlling it, so I headed to the ladder to drill out the hole. It's nice and sharp, had no problem digging into the wood, making quick work of it and I had a 6" hole in the wood in a minute. It didn't struggle whatsoever, the wood was 3/4", though it did set off Metabo's RFC system multiple times even though the drill wasn't being twisted (seems to be from the weight and all that extra energy spinning) - going to test another brand drill on the second hole to see if their system is just too sensitive. Overall very happy with this saw, would definitely recommend it for others - it's great if you need something affordable, but doesn't compromise it's performance.

I changed out my old and cracked marine speakers. So I had to make a 5-1/2 inch hole over a 4-1/2 existing hole. Pain in the butt, however with a block of wood placed inside the existing hole it gave me a guide to expand the 4 holes to 5-1/2 inches. The only issues were the boat is on the water in Florida and it was 100 degrees hot. The hole saw worked perfectly. The price and quick delivery was excellent. It’s a great product, it also effortlessly cut through steel that was behind the fiberglass. Success!!! I’m glad that’s over with. The new speakers sound amazing!!!

For about a third of the price of a similar hole saw at Home Depot, this did the job just as well. It’s probably not professional grade, but for a homeowner doing an occasional project, it’s perfect. A very specialized tool that I’m glad I was able to find without spending a fortune.

Worked well. Misjudged the thickness of my desk surface. The desktop was a piece of 2" (1-3/4" real) butcher block thickness. Forgot to include the shank holding the drill bit, so it didn't go all the way through. Rotated to other side of the desktop and finished up the hold. It worked as advertised. Worked well and the actual drilling went smoothly. I would highly recommend.

I needed to cut a 6" hole in an outside wall for a new vent. It worked very well, heavy weight, sharp and went through with little effort. However, I found I couldn't get the mounting hardware to tighten down completely which made it feel loose. It didn't affect using it but I thought the arbor should have been a solid connection. I put it in my tool box, end of story. Thanks, ELM

I bought the 8” hole saw to cut holes in my roof for installing snowventco attic vents. It did the job reasonably well, but it certainly wouldn’t hold up to repeated use. I only needed it for 4 holes, and it was noticeably harder to cut on the last one. But it did what I needed, and I tossed it after. I had to stop half way through each hole to let it cool down. A skilled skilsaw operator could have cut quicker, but I was satisfied which this. So yeah, the quality is not amazing. But it’s cheap and if you consider it disposable and only need a few holes it’s not bad.

For an inexpensive hole saw, it works great! It easily cut through the 1/4" plexiglass without any issues. The drill bit is also very good and it clamped on well. Definitely worth it. I'm very glad I purchased it!!

I needed a single holesaw (3/4") to replace one from my set of holesaws that had gone missing. I was not expecting much from an Amazon purchase of a tool. I was pleasantly surprised. It came quickly, it came with a spare arbor, and it worked well for my small project. (I only had to drill 2 holes). While I have bought and owned better quality tools, for the orice...I was quite happy with the holes away.
