Easy Cutting Lens Glass Circle Cutter Tool Stained Glass & Regular Glass

Pleasantly surprised at how easy it is to cut all sizes of circles. I used it on cathedral stained glass and got perfect results every time. Make sure to use oil with each cut! The measurement gauge on the platform is good. I ended up printing out my own exact circle sizes and taping it to the platform, which worked great.

Thankfully, one or two reviewers mentioned using tool-drawer, anti-skid material on the surface where you set the glass to be cut. This works beautifully, allowing my cut lines to start and finish in line with each other, perfectly. For the size-scale markings on the cutting bar, I recommend the purchasers insert this bar "backwards." This way, the setscrew doesn't dig into the circle-size markings, and they will remain visible indefinitely. Using your palm on the cutting knob was another great recommendation made by others, and used by me. This method keeps the cutter moving smoothly, with even pressure, resulting in a very clean cut. I even managed to cut one of my circles from within the square of glass, leaving a clean hole in the blank, and a perfectly formed circle for my medallion. (No break-out lines needed!)

I just love this thing and am glad I didn't pay the extra money for the expensive one. It was a little rough at first but did cut very nice circles. Then I shot a little WD40 silicone lubricant down the crankshaft and WOW it's amazing now! So easy to cut with! And perfect circles every time. And I did as so many other users did and bought some liner (I used the mesh kitchen drawer liner from the dollar store) to keep the glass from sliding around. Excellent purchase.

We used this to cut very thin (less than 1 mm thick) glass. It takes practice to figure out how much pressure to apply as well as how many times to go around to get the cut to work without cracking the glass on the inside of the cut circle. We used a small amount of silicon grease on the area where the cutting wheel touched the glass which reduced the cracking. We also used lab tape, or poster putty, to secure the glass to the blue base. We couldn't use the spongy cabinet liner others recommended because our glass is so thin that any uneven pressure could crack the glass. We first practiced on a package of inexpensive 40 mm coverslips. After practicing on ~100 coverslips, we were ready to cut our precious project. Voile! It worked. The only note is that the blue base is not perfectly flat as it has embossed numbers on one side (to help one judge diameter). This wouldn't have been noticeable if our glass wasn't so thin. Very thankful to manufacturer, supplier, and Amazon for providing this piece of equipment at a reasonable cost.

Works as advertised. I don’t understand the complaint for a purchaser that it did not work; he must not have read the enclosed instructions. Perfect circle, perfectly sized to complete my piece on my first attempt, without a practice piece first. I would recommend, as I would recommend also reading directions.

i practiced cutting circles with this device no suction ... I taped to glass to hold device steady requires coordinating pressure on center plus turning 360 degrees ... finally I got good circles instructions are missing information about making sure that cutting edge (1 of 3) is positioned on glass and does require lots of radiating cuts to release scored circle bottom line - works - but requires mastering the tool first - not particularly easy

I read all the reviews on this circle cutter before ordering it. I took the advise of several reviewers and used a piece of no-slip silicone under the pieces of glass that I was cutting. (this case it was a silicone hot pad that I use for hot plates and pans when cooking). The glass never slipped. In addition, I also used my full palm to turn the handle. The glass broke even each time. There are NO Instructions for using this cutter included so reading the reviews really made all the difference.

The video shows it cutting but they don’t actually take it out to show the circles. Such a rip off! This thing wouldn’t cut melted butter and I followed the directions. All it did was damage my product.
