## Questions & Answers

**Q: What is the max rpm on this? can i use it on my 4 1/2" angle grinder?**
A: The maximum RPM is 4000 for this bit, you will need to use a variable speed angle grinder for it.

Thank you!

**Q: Will this work on porcelain tile?**
A: Yes, this will work on porcelain tile.

Thank you!

**Q: Will this work on Flagstone?**
A: It will work but flagstone is soft, sandy, and brittle for shaping tools. I'd go slow to keep stresses low on the stone. 

I'd probably saw bevels and sand/grind round with a mason blade and a light touch on medium to fine grit grindind. Either method still runs risk of chipping the layered flagstone though.
