## Questions & Answers

**Q: Can this be attached to a standard drill?**
A: This has a threaded 5/8" arbor for a hand grinder.  You will need a large 3/4" drill and an 5/8 arbor.  I wouldn't recommend it.

**Q: do they make these to fit the 7 inch dewalt angle grinder?**
A: Yes.  When the 4 inch was too small for my project I purchased a 7 inch grinder, grinding wheel, and shroud through amazon.  The 7 equipment is a  significantly larger investment than the 4 1/2.  7 inch equipment: Grinder - DWE4557, floor grinding wheel - DW4775, and shroud DWE46170.

**Q: Has anyone used this with the herzo dust shroud? I had issues with another disc being too shallow for the dust shroud so im looking for a different di**
A: I had no problem

**Q: Will this grinding wheel grind down a high spot pushed up by roots on my driveway?  I have a raised section about 3/4” high causing a tripping hazard.**
A: We recommend our 4-1/2" double row diamond cup grinding wheel for dry grinding of concrete and other masonry materials.
