Godora Stained Glass Grinder, Mini Stained Glass Kit with 5/8" & 1" Grinder Bits, Widely Used for Glass Processing Arts and Decoration

We bought this because we are building partial walls out of cut bottles. And boy-oh-boy did we need to find an easier way! This little unit works exactly as advertised. Keep in mind that it WILL NOT cut the bottle all the way thru… it’s not supposed to and that expectation is totally unrealistic. It simply scores the glass. We have cut everything from wine bottles to beer bottles to Jarrito bottles and everything in between. If the glass is smooth and not ribbed, it’s going to work. While it’s easy to use… you have to follow the instructions and be patient with the process. Any failures is not the fault of the unit itself, it’s simply the luck of the draw. Not every bottle is going to cut perfectly. There are a lot of variables…. Including the thickness of the bottle. We had been cutting bottle after bottle all day with a lot of success and then tried a Bud Platinum bottle (for that beautiful blue glass) and it shattered almost immediately. It was MUCH thinner than the others and our usual amount of pressure was too much. So we adjusted our technique for different types and have now had great success with the Bud, as well. TECHNIQUE FOR SUCCESS: We found that getting the label and all of the adhesive off first is crucial. You don’t want to dull the blade or have the blade press the adhesive into the exact spot you expect to cut cleanly. Soak the bottles in soapy water, the labels will slide right off. Then we sprayed a Dawn/rubbing alcohol/water spray and used a wire brush or other scrubber, steel wool, etc to get that adhesive. SOAKING in soapy water was way more effective (and cheaper) than Goo-b-gone and all that other stuff. Now you’re ready to use the cutter. Be firm but not crazy. Don’t monkey the heck out of it. Pay attention to where you start the scoring line so you can join it perfectly. DO NOT go around and around… one time only. It won’t look like much but it is enough. Once scored, we would spin the bottle in a pot of VERY HOT BUT NOT BOILING water, heat it up, pull it out, set the bottle sideways in a frying pan with the neck raised on the edge of the pan and slowly spin it while holding an ice cube on the score mark. Repeat as needed: Heat, ice, heat, ice. Sometimes it releases immediately and sometimes it takes a few rotations. But it works. We have been able to cut over 100 bottles so far and have not even changed the blade yet. Well worth the money! The design is simple and effective. It’s tedious work but this unit helps SO MUCH! Thank you!

I bought this to cut wine bottles into drinking glasses. It scores bottles consistently and is easy to use, especially for standard wine bottles. That said, the cut edge is very sharp and still requires grinding and sanding if you want a drink-safe rim. This works well as a first step, but it’s not a complete solution by itself. If you’re planning to make usable glasses, pair this with a glass grinder and wet sanding.

Great for round bottles only. Works amazing on round bottles. This does not cut mason jar shape very well at all wish it stated that a little clearer. There’s some diamond drill tip in there but no idea how to use it. There’s no instructions on it.

Great product for my stained glass projects

Works great! I have been doing my cutting freehand for about a year, so I am reviewing from the lens of someone who couldn’t get a clean cut semi-consistently (I only successfully cut two bottles out of a dozen broken ones). The o-rings fit very well on standard bottles, and put enough pressure on the scoring area that I only need a single ring for cuts close to the neck. The gloves were tiny but I was still able to use them since I didn’t have any on hand. I haven’t tried it on smaller bottles but I assume I would need to use the hand tool still. I didn’t read the instructions as I have cut glass before, and I was able to get a clean cut within two tries! The included sandpaper was a little finer than I am used to, but I was already planning on using my own silicone sandpaper. Highly recommend!

Not at all what I was hoping for. It doesn’t stay level so no cuts are strait. I am a beginner but I had a glass cutter I got almost ten years ago and I was cutting bottles drunk as a skunk. Now I’m damn near 40 and California sober I can’t keep this bottle straight. Then you can’t cut small pieces. The most that you can take off is 4 and a half inches and you have one wheel to balance on. Not like two made any difference. I wanted this to work so bad and we are so close to a bad a product but we just missed the mark. And the initial cut line. We did get one decent split!

Works great! I use it regularly and I love it.

First time used, the whole thing broke! I even had the instructions out to make sure I was doing it right.

Passt super und man braucht nur einen Tropfen

Great product!

A good product to have with the glass cutter. Makes it easy to cut by having the oil.

It was what I needed to help with my leaded glass work

Ist gut, mit der Pipette die dabei ist, ist es leicht zu dosieren
