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 Cuts perfect circles I needed to cut 6 holes for recessed lighting in my kitchen and decided to purchase this tool. It saved alot of time and makes perfect circles. Helpful hint: use a nail to punch your center hole completely through the drywall and scribe the cuts on both sides of the material, then gently knock out the cutout with a hammer. Pops out clean, did'nt even need a utility knife to clean up the cuts. Great timesaving tool! August 8, 2010
Rated 4.0 out of 5.0 by Needed to cut Several circles for Light Fixtures. I was looking to put Drywall on the ceiling of my workshop. I had approximately 10 circular light fixtures to cut out. I discovered this unique tool to help cutout drywall for the fixture. Wow!! what a savings of time. This tool, makes cutting circular holes, significantly easier. No more tracing the hole with a pencil, then using a knife to make the hole. Saved me a significant amount of time. The price was well worth the savings in time. November 27, 2006
Rated 4.0 out of 5.0 by Cut both sides of drywall Used to cut holes for recess lighting in 1/2" drywall. Cut both sides of drywall and pound out with a mallet or the palm of your hand. Cut 18 6" dia. holes without a problem using the method above. September 4, 2012
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
