Jonard Tools AHC-10, Professional Grade Round Hole Saw Cutter, Includes Dust Shield and Case, Cuts Plywood Plasterboard Sheetrock Acrylic Up to 1 1/16” Thick, Adjustable Hole Size 2.2” to 10”, Silver

At first, I was a little surprised by the price but when it arrived, I quickly discovered why. Very high quality product with a storage case and spare? teeth. I have a smaller adjustable hole saw with dust shield that I bought at one of the big hardware stores but it only goes up to six inches and is nowhere near the quality of this one. I think that one was $30. This one was $90. Not the greatest value but I dont mind paying for the quality.

I don’t understand all the “it doesn’t work with a cordless drill” comments. It works just fine! I cut four holes in my ceiling in about 5 minutes for surround speakers (I chose this model because the Sonos architectural speakers require an 8-1/4” cutout). And it worked perfectly with my dewalt 20v cordless drill. You need to spin it fast and cut slowly (maybe 10 seconds in drywall)...but there is no mess, and the hole is perfect! Highly recommend this tool!

For the price, the quality and machining should have been a little better. It got the job done, and really does keep the mess to a minimum. I do recommend a drill with a side handle. The larger your hole the more difficult to avoid tear out with a standard cordless drill.

There was no mess/dust after drilling a hole in the ceiling.

Worked great for cutting in supply diffusers on drywall. I decided on a new construction job to try its claimed ability to cut plywood/osb. The trick with drywall was to go slow with a fast drill speed to keep the teeth from jamming. I did the same thing on OSB, it tried to cut but ended up snagging and breaking the pilot bit before the drills anti-kickback could do its thing. The saw is also VERY particular about keeping COMPLETELY or else its try to skip.
