14 Pack 4 Inch Diamond Polishing Pads Kit with 2PCS 5/8’’-11 Backer Pad 12PCS Wet/Dry Polish Pad Set for Drill Grinder Polisher 50-8000 Grit Pads for Granite Marble Stone Concrete Countertop Quartz

I used with my cordless drill and charged lots of batteries.After cutting a 16 sided "circle" with a diamond blade on my angle grinder, I put the 50&100 to work rounding the top edge, cleaning up the cuts and rounding the points. I used the pads in succession up to 300 dry. I gave my drill a break for a couple days (wife still suspect how it will turn out).Starting with the 500, I used a spray bottle to wet few sides, sanded, sprayed, sanded, sprayed, sanded and when all sides were done I wiped the edges before swapping to the next pad and starting the spray & sand x3 process over again. I got up to the 2000 and was tired of walking in circles, so I quit for the day.The next day I found a couple small spots that weren't as polished as the rest, but the wife said it looked good enough. She already suggested cutting and polishing another piece from what's left.Are the cut edges smooth and have a shine like the top does? Yes. Now I have to attach it to the lazy susan ring. Maybe some day I'll fix the small imperfections and work up to the 8000 pad.The 50&100 got the most wear (2 of each would make the kit better).

Did exactly what I needed them to do which was make a concrete countertop slick

I’ve been using for lapidary. Polishing obsidian and thunder eggs.Works well.

Was expecting to be disappointed, but this polishing kit worked as it was advertised to. You could really tell the difference of the different grit levels. Polished the marble tile edges as I wanted.

I am in the process of making concrete Terrazzo pieces and these discs make the job so much easier. Also, the price is great. They are easy to change, but the Velcro sticks super good and doesn’t come off in the process of grinding. The amount of different grits helps you go from a very rough to a shiny Surface

Easy to use. Gave a nice finish to edge.

Not as good as I thought but never used them before. Seem to work okay. Will use it awhile to see if it works. If used in a drill ensure your drill is turned to unscrew or the pad will unscrew and come off.

I was a bit hesitant and a first timer stripping stains and there were some chip/nicks in one of the tops. This was the second one order due to the fact the first one was an odd size (not the standard USA 5/8"-11) and would not attach to the polisher. After a week delay, these polishing pads did the job for two marble table tops. I have a third not to bad of shape and I know these pads would of handled the job on that one too.
