Red Devil 102370 Professional Glass Cutter

Cuts glass. Made of pretty heavy duty metal.

Worked great to cut glass for frame once I practiced on a piece of broken glass. I watched a video on exactly how to do it and it worked! Hold the tool like a pencil...press into glass with firm pressure so you hear the scratching noise...don't keep going over the glass, just once is all you need.

Broke after 3 uses. This worked great for the first 2 pieces I cut for some small picture frames, but on the third use I couldn’t figure out why I wasn’t able to get a good score anymore. It appears the pin that holds the wheel in place worked its way loose and fell out. It is impossibly small and I never found it, probably not repairable even if I did. Useless tool now.

Seems to be a quality tool gave it a four-star rating only because I haven't used it yet

Love this cutter.

I bought this to scratch in front of a split on my vehicle windshield to stop progress; didn't work for me, but did cut the glass some.

I bought a glass aquarium lid online and was sure I knew the dimensions I needed. I was off ¼"(insert face palm here). Since returning it wasn't an option, I knew I needed a glass cutter. This was the same brand that I remembered using decades ago on a construction project I worked on so I ordered it. I received it very quickly.I knew that taking just a ¼" off the edge of the two piece lid would be tricky, especially with the hinge not allowing me to lay the glass flat on the work table. I watched a few YouTube vids on the subject and found two that addressed the subject of trimming a small piece off the glass with out it running into the big piece. It's not just a simple score and snap like on bigger pieces.With the instructions from YouTube I learned to make the score and then use the little ball on the end to tap the bottom of the score line, while giving gentle pressure to the top side and carefully turn the score line into a running crack that can be snapped off with some pliers. It was a fairly clean edge but did need some smoothing with a piece of coarse emery cloth and a little help with the Dremel sanding drum.

It cut the glass well however the handle broke in half with just the pressure of my hand. Not very strong.
