STADEADiamond Polishing Pads for Angle Grinder, 4 inch Wet/Dry 8 Piece Set Granite Stone Concrete Marble

I was surprised at the quality of the disks for the cost. I bought the assortment. I was a bit leary of the disks rubber structure, as it looked a bit to aggressive and might burn the granite or leave swirl marks, Not so if used with patience and LOTS OF WATER. Combined with a light pressure !You can save yourself a considerable amount of money with this assortment in repairing minor scratches and such. Just take it easy, Check your work area often to see how things are doing, and how the light is being reflected. Messy it is, no getting around that. Keep in mind that the moment of the grinding wheel should NEVER stop being moved about, or you'll have a donut hole. You have diamonds at work here !I think the adapter plate is a must also. Though it is a bit of a problem getting the grinding pads centered right to minimize vibration. Otherwise, a thumbs up to the company.

I purchased these to polish some small stones that I had cut using my drill press. I was surprised at how quickly I could move through the different grits to achieve the desired results. Was much more economical for the small project I had than purchasing an expensive flat lap machine and discs.

This was my first time cutting, buffing and polishing a ceramic countertop. We remodeled our kitchen and our daughter wanted to old countertop for her kitchen. Of course the dimensions were not right so I was asked to cut and cleanup the edges. The polishing pads worked well. I will mention that the pads attach with Velcro. There were several times upon initial startup of the tool that the pad "took flight", hitting various objects like the garage door and my truck...with power. Be sure you understand this and keep others clear should you every try these pads. Bottom line...I would buy again and recommend to family and friends.

I used these on granite with a speed reducing controller, such as can be purchased for a router. My angle grinder is 14,000 rpm and the disks would not stay in balance.I personally would not expect a Velcro attached disc to do so at such speeds .They performed excellently and I expect will do so for many more cut edges and re-polishing's

I watched a bunch of videos on how to polish granite, then chose the techniques that were common among all the successful ones. Use water to keep the material/pads lubricated and cool. Don't exceed the speed recommended on the pads. Use a variable speed grinder - the mounting pad will fit right on it. Keep moving! If you have a scrap piece, practice first, you'll get better as you 'feel' how the surface is responding to the polishing process. Don't skip any pads... the sequence is very important since each pad has the right grit to remove the scratches created from the previous pad. If you skip or don't polish a pad long enough the finish will be a bit dull and you get to go back and do it over again. This is the way!

These pads did a good job of smoothing up a quarts countertop that I had to cut to size. The only problem I had was with the final (smoothest) disk because it literally blew apart as soon as I turned on my polishing tool. So, I never did get the final polish, but what I ended up with was pretty darn smoothe, although it could be better had I been able to use the smoothest pad.

Winner!! These along with a bullnose saw blade saved me some serious cash! I used the polishing pads after cutting my travertine bullnose. Travertine bullnose is ridiculously expensive if you can find it.As mentioned in other reviews you MUST use the pads in order, there is no shortcut. I was able to stop at the 800 grit pad, this matched the factory surface of the tile saving me some time.With some creativity, I mounted my pad to a 20V DeWalt drill, set it on the third speed and it worked flawlessly. A typical grinder will spin WAY TO FAST for these pads, look at your grinder for the rpm first, the max rpm is listed on Amazon. This listing on Amazon is different than what is listed on the backing pad, that is the RPM for the backing pad not the actual pads. Amazon list the speed for the pads themselves.Would I buy them again, absolutely!!!

I put a sink in my garage and got some granite remnants. I tried using sandpaper to do the bullnose and edges, but the process was very slow and consumed sandpaper like crazy. I ordered these diamond polishing pads, and it was a whole different experience. Each pad was good for the whole job (bullnose, and three backsplash pieces) and showed no signs of wear or reduced capability. My pads will be good for another job. The end result was shiny and pretty - I'm very happy with these pads.
