16PCS Wet Dry Diamond Polishing Pad Kit, 4 Inch Diamond Sanding Pad 30-6000 Grit with 5/8''-11 Thread Backer Plate for Concrete Marble Quartz Granite Countertop Stone & Tile Polishing

Resurfaced a marble sideboard. Worked very well. Make sure you use a tool with a slow enough speed, too fast and you will have problems

I bought them for my husband, he says they are great wheels

To be honest, I didn't expect much out of these at all. They got the job I needed done (sanding a concrete countertop). The only complaints are the wear rate, they clog easily when wet sanding and the grit numbers on them are hard to see (on a few of them) and some disappeared after mild use.

Good products,good value

Works great

I resized a granite counter slab, and these were awesome for polishing the cut edge. I've never used a similar product, so nothing to compare to. I only used them on one edge, but they did the trick. I was very happy for the price.

no reason that hesitate here go ahead and get these they are awesome I wish they made actually 7 in ones I don't see that anywhere

Worked very well on granite

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

凸凹した石には違う方法が良いと思われます。 他の方法は、どんなものがありますかね？
