## Questions & Answers

**Q: Will this be good for grinding down weld on steel?**
A: This will grind steel very well, but it's an expensive way to do it... A coarse grit wheel would work just as well, for less money.

**Q: Would this be an appropriate disc to use for stripping old paint off of concrete without heavy material removal to prep for installing stone tile?**
A: Dear,I'm sorry for that.This grinding cup can't be used in that.It's used in grinding marble ,granite.

**Q: will this effectively remove mill scale from steel?**
A: No

**Q: How good is this at removing concrete? I need to grind a shallow U shaped channel about 1" deep at center (about 5" wide) for redirecting rain water.**
A: I used this wheel to prepare a granite stone for a memorial plaque. It is a remarkable cutting wheel for that material. My job was not as big as the one you describe but it will definitely cut concrete.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Effective and long lasting
*by J***W on June 11, 2025*

This worked great to grind the finish off of my concrete slide. I was able to do the entire slide and it still has plenty of life left for other jobs.

### ⭐⭐⭐⭐⭐ Quick easy work on carbide teeth for forestry mulching head on excavator.
*by R***W on April 26, 2025*

Was hesitant for price but works great. Use this on carbide teeth for a forestry mulcher cutter head on my excavator. Regular grinding disc's wouldn't touch them. This takes mere seconds on each one. After a few uses its still holding up well. Highly recommended.

### ⭐⭐⭐⭐⭐ Grinding disk.
*by D***D on May 13, 2025*

Grinding desk, works really good. Wow, I definitely recommend it if you need to grind down some nasty welds etc. 👍🏻👍🏻👍🏻👍🏻👍🏻
