4 Inch 12PCS Diamond Polishing Pads

I poured some industrial looking concrete counter tops for an outdoor kitchen I built under a new covered patio. These actually did fine on a 5" DA sander. I started with 50 grit and went to 800 grit, all wet sanded. I stopped there because I wanted to leave the air bubble voids and the final finish was to be paint anyway. But there's little doubt they do the job - quickly cutting through and leveling the surface. I would suggest you take a photo or keep notes as to which color is which grit because the process of wet sanding washed away the grit size as printed on the under-side of the pads. Once the pads were dry I used as Sharpie to note the grit size for the next time I need to use them.

Works great for polishing/sanding porcelain tile after cutting. Gives a nice factory looking edge back to it.

High quality. Worked well to polish a granite cap for my new bathroom. Was able to step through the levels to easily polish granite slab to create a rounded edge.

Very good product

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!

Good quality product, fair pricing and very quick shipping. The Velcro is very strong in this product, which is great. It's easy enough to switch between grits and keep going. Did a great job polishing up my quartz.

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。

安いので精度は悪いです ドリルで面研できるので便利ですね 普通に使えますよ

Muy utiles para areas pequeñas.

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

Worked great to refurbish my marble countertop. I finished the process by using a marble polishing powder & after finishing, the surface was as nicely polished as when we first purchased the countertop.
