## 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.
