4 Inch 12PCS Diamond Polishing Pads

Hello, I never write reviews, but these pads worked well and I hope this helps someone. I bought a variable-speed polisher to refinish my yellow marble bathroom countertops. The lowest speed was 1000 RPM, and at first I thought everything turned out great because it looked perfect under the bathroom lights. Then the next morning, natural light exposed major swirl marks everywhere. I couldn’t figure out if it was the pads, my technique, or the machine itself. After a lot of research, I realized marble polishing is often much easier to control at lower speeds — around 400–500 RPM. I’m a small woman and honestly struggled controlling the heavier polisher and even level 1 felt too fast. It felt fast, bouncy, and hard to keep steady. I spent forever researching lower-RPM polishers and new pads, but most of the good ones were $400. Then it suddenly occurred to me to try my $25 cheap cordless electric spin scrubber from Amazon that had a 4-inch Velcro attachment head. Game changer!!! I attached the polishing pads to it and it worked like a dream. It was much easier to control, created less mess (water was shooting everywhere before), and because I could keep smooth, even pressure at a slower speed, it completely eliminated the swirl marks. I did have to go back down to 400 grit and work my way back up to 1500 for a honed marble look and then sealed it with 511 after. I’m so happy with how the countertops turned out that I’m about to do another bathroom next. Hope this helps someone else struggling with marble polishing!

Excellent product works great for polishing rocks and concrete

Polished outdoor concrete countertop - decided to make this purchase to test the difficulty of polishing colored concrete. Surprisingly everything worked quite well. Polished 2 square feet in 45 minutes and the result was great. This product is only going to work for small areas. Had to frequently reposition the abrasive pads on the backer pad - I think my grinder speed was too high.

As advertised

So i actually used these pads to refinish my terazzo floors. They are not directly intended for terazzo flooring but i must say im pretty impressed. Ive done about 600sqft of floors so far from 50-3000 grit with 7" pads. The 50 ate down my 1961 floors to a crisp white again, as i worked my way up it made my flooring pop. The portions ive done to 3k shine really really nice. For being designed to do countertop spots/repairs and not an entire house of floors, i have yet to have to buy new pads halfway in. For the money you cant beat it. Ive noticed the lower grits like slow speed, higher grits high speed play around with the pressure and do it wet or itll grab a little. But overall extremely pleased

Got this to use with some granite counter back splashes. These worked very well to get the unfinished edges smoothed out. It does take a bit of time, and doesn't get it all the way to a mirror finish, but gets it smooth with a decent shine.

Velcro isn't very good and disks tend to fly off at high speed. Can be very dangerous. Functionally they sand very well. I attached my pads to a drill first, used them for a minute to soften them, and then put them on the grinder and they stayed attached much better. Must be used at low speeds if on an angle grinder or they could seriously injure you

The diamond sanding pads are great, work perfectly. The backing pad unfortunately is not. The yellow foam ripped off the plastic in the middle of being used.

鏡をダイヤモンド入りの水垢落としを使ったら傷だらけになりました。まったく見えない・・・ その後セリウム粉末を買ったが薄い小傷しか落ちないのでこの商品を買いました。 指や爪でわかるガラス傷はこの商品買った方が一瞬でツルツルになります。 水平に当てるのがコツです。斜めに研磨すると深い傷が入ります。細かいので削れば消えます。 400番→いろいろ試し最後6000番だったかなで指で触っても段差を感じないまでの擦り傷になりました。 最後はセリウムで研磨しました。セリウムの代わりは重曹１水１で練重曹を作ればセリウムと同じぐらいの研磨が出来るとかできないとか？聞きました。セリウムは化学研磨なのできれいになります。 最後セリウムで磨き綺麗に鏡が復活しました。

Very good product

Excelente producto

Fast delivery and excellent product for polishing fog light glass that is fine pitted from road dust & dirt

Not working properly, and poor quality. All pads seem the same grit number.
