Great product
Does exactly what it says on the tin...Grinds concrete! and fast.. you need to keep it moving all the time on concrete or it will dig a hole pretty quick...
i am on my second one after 8 months so they are great value.

NOTE: these guys kick up a lot of dust, i would recommend using the dust shroud and vaccuum

Polishing wheel not grinding wheel
Dewalt wheel did a fine job polishing concrete. Did not remove concrete nearly as fast as Rigid Double Row Diamond wheel.

Poorly designed
Once the wheel is on the grinder you need a special thin wrench to remove it as the nut is on the inside and should be on the other side. Works OK but not as good as expected

?Will this work with Factory Reconditioned Dewalt DWE4011R 4-1/2 in. 12,000 RPM 7.0 Amp Angle Grinder with One-Touch Guard?
A shopper on Apr 12, 2017
BEST ANSWER: Yes, these two Dewalt items are compatible with each other
Do you have the thin spanner wrench necessary to remove the DeWalt DW4774 4 1/2" diamond cup wheel from the grinder spindle? So far, this has been a critical design flaw, and a huge time wasting and costly anoyance. Hope you can help!
