Here’s What Artists Are Saying…

I just LOVE THE GRINDER®! I have used many brands of grinders through a lot of years (I began working with art glass as a hobby in the 1970s). I used grinders in traditional ways for large and small stained glass cuts, but around 2008, I also started using them for “cold working” the edges of my thicker dammed fused artwork, prior to fire-polish them (I always referred to my grinders as the poor artist’s lap wheel). As such, grinders became a multi-faceted and important piece of studio equipment.

I have now been using THE GRINDER® in my studio. I am hooked, again! Just like the Quick-Fit Bit® transformed my grinder head replacement/swap experience, I am finding THE GRINDER® to be an incredible step up in my grinder user experience. It’s motor is a powerful and super quiet workhorse. The increased work surface is a major bonus for those of us that work with larger cuts of glass. One of the things I really appreciate is the built-in light that runs most of the length of the piece and then there’s the rubber splash guard and removable water tray. Wow do those make clean-up so much easier!

I have one of your “the Grinder” and it is just the best thing since sliced bread I use it with both the 1″ & 3/4″ quick fit bits

You are all amazing. I only wish I had room for another grinder in my studio.

Peggy P.

I am so impressed with this grinder. It was easy to put together, and easy to take apart for cleaning. The features are fantastic.

In the 39 years I’ve been working with glass, this is by far the best grinder I have ever used. Honestly! It’s a joy to use it.

Many thanks to the person or team that designed this grinder.

I received my Grinder last week and it is more than I expected !! Fabulous machine. I’m not surprised that the success of The Grinder has been overwhelming. It is a fabulous product, for me the top selling points are the strip of LEDs, genius, and the size of the worktop, perfect… The Grinder is the product that we have been waiting for unconsciously. Here’s to continued success !!!! Or as we say here in France, Bonne continuation !!

I am a custom stained glass artist and recently purchased The Grinder! Talk about loving it! I have several other grinders but this is by far my favorite, I guess the others will have to go to the closet… Cleanup is a breeze and so easy, using the led lights makes it easier to use rather than using a lamp to highlight the areas your grinding. I also appreciate the large surface area, and being able to view the water reservoir. I have not used the second level yet but I’m sure with all the designs I will. Great Technology! and worth the price!Delia R.

I am a fuser and use the grinder to smooth out flakes. Used it yesterday and worked perfectly.

Eliminate carrying a heavy awkward grinder to the sink or potentially spilling its contents on floors and work surfaces. Any accumulated glass grit can be cleaned out with the included scraper and disposed of or repurposed.

The uniquely designed main grid has incorporated supports and baffles on the underside to stabilize work surface and limit water movement during tray transport.
