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.

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

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.

I think I know why some of you had a miserable time using this tool. Mine came with one of the cutters facing the wrong way! The instructions dont make this clear, but as an experienced machinist I understand carbide cutting tools. The flat carbide surface must face the direction of the cut. If you lay the cutter arbor assembly in front of you on a surface, with the the drill tip pointing away from you, one of the carbide tools will be on the left, the other on the right. For clockwise drill rotation, the cutter on the left should have the flat carbide surface facing up. The left one should be facing down. That way as the assembly rotates, both cutters are engaging the material in face-first orientation. (See my first photo and visualize it rotating clockwise with the drill.) Mine came with both cutters facing up. One cutter would have just dragged through. I guess the Chinese assemblers werent trained. Also, for optimal cutting, the sharp corner of the cutting tool should be outermost, as in my second photo. But two of mine came with the opposite orientation, as shown in my third photo. Perhaps their intent was to use one of each. That way you would be cutting the inside and outside kerf in unison. Worth a try. The most important thing is to point them in the correct direction, as in my first photo. Otherwise this is an elegant solution to minimizing dusty hole cutting in sheet rock. Nice case. Fits my shop vacuum perfectly. CHECK YOUR DIAMETER SETTING AND TIGHTEN EVERYTHING WELL. Practice on some scrap material if you can, and check the screw tightness every hole.

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!
