## Questions & Answers

**Q: Does anyone have a problem with the finer grits delaminating as with the Uxcell brands?**
A: I have not had any problems yet.

**Q: do you make one that is coated on both sides?**
A: Hello, only one side is coated diamond particles.
The back of diamond grinding disk is a smooth and flat steel plate, and there are no diamond particles.

**Q: Can this be used for diamond? SiC? What is the roughness of the lap?**
A: The roughness is 3000 grit... and it is diamond

**Q: Where is it made?**
A: I assume that they are made in China. I have 5 different grits that I use to smooth the edges of glass wine bottles that I cut.  I put them on a wooden backer, mount them on my wood lathe,  and use a spray bottle of water to keep them wet while I grind glass.  This prevents over heating and having ground glass floating around my shop.  A bucket catches the drips.  They have worked very well and have lasted well.
