Having used ours for marking cloth, we cannot say with certainty, however it is quite strong and the supplied cutter seems sharp and capable of serous cutting.

Rated 4.2 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by Multipurpose circle scriber/cutter We were looking for a modest sewing tool that could be set to any diameter for marking or cutting cloth, and had about given up when looking at sewing stores. Then on a last minute thought, we looked at the tool section of HD. This unlikely looking tool was perfect. The sewing project of finished and we adapted the cutter head to hold a marking pen.

Rated 4.0 out of 5.0 by good product does a nice job for cutting holes for ceiling boxes. No big gaps around the box. March 29, 2016
Rated 4.0 out of 5.0 by Not bad for the price - well built For less then 10 dollars how could you not get something like this? I even use it for wood working when I need to draw an ark or circle November 20, 2015
Rated 4.0 out of 5.0 by Works if you know what it is for... The review from Pete saying it only cuts 1/8" deep is right, but that is what it is intended to do. With drywall you only cut through the paper, score the gypsum and break the rest. A reviewer down the list correctly states the best way to use this tool is to score both sides then pop it with a mallet or your hand and you'll have a perfect hole. If you have to cut from one side only, you should plan on using this tool to cut as deep as you can to get a nice trim cut on the face of the drywall and then finish the cut with your knife or drywall keyhole saw. If you want to cut all the way through from the face, invest in a rotozip and the circle cutter to go with it. September 27, 2013
Rated 5.0 out of 5.0 by Circle cutter Its a great tool I am a professional drywall installer I use it every day, does perfect circles no need for expensice drill pieces. February 25, 2015
Rated 4.0 out of 5.0 by worked well The items worked well for what I needed. The cutting wheel could be little larger for a faster cut time and overall better results, however, only cutting a few pieces its a great tool. February 17, 2015
Rated 5.0 out of 5.0 by Works Great for cutting in speakers and downlights Like some other reviewers indicated, this can either be used on both sides to finish the job or to score one side and finish cut with a drywall saw. I performed the latter. Worked great to confirm that I had a perfect circle for speakers and downlights. No issues, so I'm happy. December 23, 2014
Rated 4.0 out of 5.0 by Circle of Light If you want perfect circle cuts for pancake light boxes, this is the tool for you. Several things to note about the operation of it. The set screw that is used to hold the proper diameter for the cut needs to be very tight, which sounds easy enough, but comes lose quite often. If this occures while turning the cutting compass your circle won't be true and the cutting well isn't a large enough circumfrence to cut all the way through a piece of half inch thick sheetrock. You have to turn the board over to cut all the way through. February 25, 2014
