4 Inch Diamond Polishing Pads with 5/8’’-11 Backer Pad, 12PCS Wet/Dry Granite Stone Polish Pad Kit for Drill, Grinder, Polisher, 50-6000 Grit Polishing Pad for Concrete Marble Rock Countertop Quartz

These pads are awesome. I used them to sand and polish an engineered quartz countertop and they worked great!

They are easy to use and did the job for a small area of stain in the marble.

PROS: These pads polished my granite countertop nicely where I needed it. The pads stick to the mount well.CONS: The wheel that mounts to the pads to the power drill falls off pretty easily, so expect to have to screw it back on or be very cognizant of the amount of pressure you use. I thought it was the direction I was running my drill but it wasn't.

Great product and quality for the price

Good enough to polish concrete countertops

Used this to sand and polish the stone tiles of the shower walls, and they did the trick, although I still need to add wax to make them look shinier.

Started with 50 and went all the way up to buffing pad and left my countertop dull (used water). Repeated the steps 3 times with same results. Now I have to pay someone to fix the dullness.***Update*** seller sent me some new pads to try out, will update results later.

Where do I start! Package came quickly, arrived in great condition. I did struggle a bit with figuring out the sanding bit, but this is on me not really knowing much about it. I used an orbital sander (Hercules brand from Harbor Freight). For a concrete patch I would initially sand with 50 and then move to 400 as this is what got me good results. Very smooth. I have yet to paint, but this is a good alternative to renting a floor grinder.
