## 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.

### ⭐⭐⭐⭐⭐ Good
*by S***. on 12 June 2025*

Seems like it will last a good while before wearing.

### ⭐⭐⭐⭐⭐ Dewalt quality
*by G***Y on 26 September 2022*

Very effective for grinding down concrete. I used it to take layers of paint off outside wall. Used it for 5 days and still no wear. It needs practise to get it to work and leave a smooth finish. Its a workhorse but not a finishing tool

### ⭐⭐⭐⭐⭐ Does the job
*by R***G on 14 April 2026*

I got this to remove thin set in a small area where i was changing tile. It worked very well and got down to the concrete quickly. I would not recommend using it indoors without a dust shroud and vacuum attached, and if you are using it outdoors, you should wear a mask at the very least. I did manage to create a couple of crescent shaped gouges in my slab, but since I'll be tiling over them it doesn't matter.
