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

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.

This is one of the best tools I’ve purchased It does exactly what it’s made for Cuts perfect holes and you have no dust flying around It’s easy to clean up and the carrying case is very nice and sturdy

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

This is a well-made accessory. Yes, you’ll need a drill with adequate torque, but what handyperson or tradie who’d spend $80+ on this hole saw doesn’t own a modern cordless drill with gobs of torque? My non-Fuel 18V Milwaukee had zero trouble with it. A side handle would definitely help stabilizing it, but I still had no issues. My only beef is that what seemed like the logical way to set the size — on the flat (outside) of the blade — is in fact wrong; you have to slide the blade holder *past* the measurement and line up the curve of the holder with the marking on the beam. Easy enough to see the wrong size on a smaller hole, but setting for an 8¼” diameter for my first try it wasn’t noticeable until I finished the cut. Now waiting for the mud to dry after putting the plug back in the wall (because it’s the only way I’ll be able to re-cut it)! I saw the error and adjusted the tool and cut three other holes in around five minutes. I have another couple of dozen holes to cut here and at another property. Oh. And really pay attention to the location of studs, blocks or furring strips/joists in the cavities you’re trying to hole. The blade will bind and the drill will buck in the blink of an eye! That first hole taught me *two* lessons, there was a block where none were expected. Overall an incredibly useful addition to my tool box.

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.
