### ⭐⭐⭐⭐⭐ 







  
  
    Worked well on thermal bluestone
  

*by J***Z on Reviewed in the United States 🇺🇸 on August 27, 2022*

I used this to round over the edge of thermal bluestone that is sitting a little proud (as intended) of an adjacent catwalk. I attached the bit to my single-speed (i.e. high RPM) grinder and used a garden hose to keep the bit cool. The bit worked perfectly, and has tons of life left after using it on 10 linear feet of bluestone. I bought the “medium” grit bit which left the edge smoother than the face of the bluestone. If I were doing it again, I’d order the “coarse” grit bit which might be a little better for this application.

### ⭐⭐⭐⭐⭐ 







  
  
    Worked great
  

*by M***K on Reviewed in the United States 🇺🇸 on April 27, 2022*

Only did 3 counter tops and a mantel, but it worked as intended.  Not sure how it would do on more than that but it looks like it is still in good shape so I would not hesitate to continue using it and/or buy it again.

### ⭐⭐⭐⭐⭐ 







  
  
    Works very well, but the bearings don't last forever
  

*by P***E on Reviewed in the United States 🇺🇸 on August 29, 2020*

I'm giving this tool 5 stars because it has worked well for me. But after a few projects (many hours of use) it started wobbling due to a bad bearing. Not surprising when you think about how this tool is used, pressed up against the material at a 90 degree angle to the axis of rotation, with considerable pressure as you run it across the material you're shaping.Since the diamond cutter part is still good, I took it apart and replaced its 2 bearings, and it's back to work. FYI,the bearings are standard 6004-2RS and 6203-2RS bearings (top and bottom).  Inexpensive and easy to replace.Seems to work well around 2000 rpm. Run plenty of water over the surface you're shaping, either with a standalone hose or use this bit in a specialty stone polishing tool that has built-in water feed.
