Stained Glass Grinder Kit with Cutting Oil, 5/8" & 1" Grinder Bits

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 received this as a gift with other stained glass supplies. I have used it a lot and it has done a good job. I’ve not had any problems with it and it grinds glass pieces quickly and easily. Cleaning it is very simple as well. I hope to get years of use out of it. The size is great for my small work area. It seems to be a reasonable cost and has held up well so far.

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.

I was unsure of success as I have cut sheet glass a million times in a rig, but it’s entirely different by hand with a glass cutter and a straight edge. This was really doable! The first go I didn’t have enough pressure for the first 1/4” and then knew better than to go back over it, so there was a little bump when it separated. Easy enough after the trial run, and it’s really interesting to see the score line get more and more through the bottle as I did the ice water/ hot water process. It took a little bit longer than instant lol. It’s some back and forth between temperatures, but after the first go it’s easy to see the process happening and what it needs. It’s maybe two minutes of the temperature changes and then it gently just separates. Really interesting to see! Just take your time and pay attention and do some practice, and then this works like a charm!

Love this small grinder for traveling in the winter in the Rv. Great for the beginner that doesn’t want to spend a lot of money upfront. I buy these for my classes when I teach and recommend them to new students just starting out. Quality & sturdiness is top notch. Easy to use & clean.

Nice glass cutter included with extra blades. As for the "contraption"... meh. Didn't work for me. I scored and scored, then did the hot/cold/hot/cold thing.. no luck. I can't seem to get ANY bottle cut using this thing. And it's clunky, inelegant, unstable, and inaccurate. In addition to a back side brace, it needs a top brace to keep any bottle solid and in place. The wheels are non-adjustable so the size is really only geared to very specific larger bottles (like wine bottles). Not at all easy to use. I would not purchase this again. The value for money was not great. It'll end up in a box in the garage, probably pretty soon. But I will use the glass oil and hand cutter that came with the contraption.

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!

I never like to leave negative reviews, but I decided to write this because Xmas is coming soon and I would hate for someone to buy this as a gift only to have the recipient be disappointed. I am an avid crafter and I was really excited to try out this bottle cutter! When I received the product and opened the box it comes in, however, I immediately noticed that it was poorly made and that some key parts were crooked. Cutting glass cleanly requires accuracy, especially when cutting round glass bottles. The rollers on the product I received are crooked, and more importantly the cutter head itself is not mounted squarely. I decided to try it out just to be sure my eyes weren’t playing tricks on me. I followed the instructions and ended up with a crazy, jagged score line that wasn’t even close to straight. Total bummer! Maybe if the pieces I mentioned could be adjusted/calibrated by the user then I could have adjusted it myself? Unfortunately they are firmly attached so I’m basically stuck with a useless product. I didn’t bother to return it because I do like the gloves and the handheld cutter it comes with, and I didn’t want to wait only to get another wonky, defective item.

Great product!

Wie beschrieben so weit gut

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
