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

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

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!

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.

drilling works great, but the bowl cannot collect the dusts well when I drilling ceiling holes. for wall drilling, it simply fine

Got it for Christmas Gift last year and my brother still uses it.

Another reviewer said this would not work with an electric drill, I had no problem using this on 5/8 drywall with a Makita 18v drill (though I did have trouble getting regular drill to hold on the shank, I had to use a 90 degree drill with a manual chuck, that worked fine. Also I used two left cutting bits so they would be symmetrical and run in the same groove.

While running wires in a previously finished basement, I wanted to avoid have to cut large amounts of drywall out. This tool makes it easy to pull out enough drywall and easily replace it with a few pieces of wood backing. Don’t hesitate to buy this.

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.

I purchased this to cut various sized holes in my ceilings for recessed lights and whole-house audio speakers; 50+ holes of various sizes. This is a substantial, heavy duty, super sturdy/rugged tool…. It is not flimsy or “cheap” in construction. Works like a champ and the dust shield really helps contain the drywall dust. The only recommendation I would make for anybody considering this tool is to buy the version with the vacuum port to further mitigate the dust by eliminating the need of dumping it. I did not know a version with a dust port was available when I purchased this.

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.
