13 Packs 4 Inch Diamond Polishing Pads with 5/8’’-11 Backer Pad 12PCS Wet/Dry Polish Pad Kit for Drill Grinder Polisher 50-8000 Grit Pads for Granite Marble Concrete Stone Countertop Quartz Polishing

Work great! Great selection of sizes and you can’t beat the price. Will order again when needed.

Absolutely love it, First things first is to properly chose a speed and pressure. Do not connect to typical grinder, typical grinder usually is 13,000rpm. This buffing pads rates up to 3,500rpm. So when people posting how they come apart is due to wrong way to use it. I had to polish edge of a counter which was cut by grinder and diamond bit, so obviously it won’t be perfect and will need to be polished. I started with 50,100,150 dry and from there to 3000 wet. Used my Dewalt XR drill and it worked out perfect. Took me about 40min to do it, challenge was to polish with one hand and with second spray water on pad. Much easier if proper tool is used or with someone’s help. I used pencil and sharpie to make sure I didn’t miss a spot. Take your time and result will surprise you.

This is very fine sanding, be aware..

I polished some marble with this for my kitchen island and they worked great in a drill. Haven’t used the finest grits yet so not sure how much of a polish they achieve

worked as described. I polished about 8 linear feet of granite and edges. results were great. only one pad had started to deteriorate. make sure you're wearing safety glasses as part of the pad did hit me in the face... but that only happened with one pad. use the middle of the pad as much as possible and not the edge of the pads. hope this helps.

I purchased these pads to remove some fine scratches from an aquarium. 20 frustrating hours later I threw the aquarium away. I started out with one of the fine pads, 3000 I think and it left circular scratches in the glass deeper than the scratches I was trying to remove so I went a little coarser to try to remove the circular scratches........ eventually I had to go all the way down to 300 and then stepped up grit by grit until I got to 1500 which grabbed and caught the edge of the pad which left deep arc shaped gouges in the glass so I had to start over again and after going back through the steps it was looking good when another of the fine pads left circular scratches again. I tested the 8000 grit (finest grit pad) on some some clean pristine glass and it left clear circular scratches.

Had to modify my existing Quartz counter. These pads allowed me to polish the edge I cut right back to the smooth, shiny appearance it had before the modifications

Works as described. Be aware that the course grit pads don't last very long. I had a 33"x 84" concrete counter, and I was barely able to get through initial cuts with the 3 course grits. Once I moved past those, I had no problems and everything worked great. Plan accordingly if you have a large project, and do not count on multiple projects
