SHDIATOOL Dry Diamond Polishing Pads 4 Inch Set of 7 Pieces Plus Alu Backer for Granite, Marble, Stone Sanding and Grinding

I used them for the first time this afternoon and they work great I recommend them to anyone

Good product

These pads seem to work better than most others I have purchased. They don't seem to leave as much residue. Speed of use is the key. Not too fast and not too slow. Mid-range around 2000 RPM works best.

Used this set along with a $40 variable speed polisher from Harbor Freight to ease the edges on some granite shower shelves I cut. Went patiently through the disc progression, misting the granite with a spray bottle as well as rinsing the discs to remove accumulated grit along the way. Wet process also cut down on the dust, but I still used PPE. End result was as you’d expect from a professional countertop fabricator. Very pleased!

When you polish any type of engineered or natural stone, the lowest grit, is one of the most important, if scratches aren’t removed , they will remain until the end. Due to scratch locations, or if you are dressing a seam up, or cleaning up after an edge profile has been sculpted, deeper scratched are going to be there. You will have to shift your pad to work them out. Think of what the imprint would look like if a man m stuck his chest to a window, now do the same for the ladies. The imprint left behind by the woman, would have areas made contact much sooner in some of the areas, causing the areas that aren’t rounded, to wear out quicker. If you have a flat surface, chances are a pad able to make constant contact, would be better. Take that with a grain of salt, this is coming from someone who polished every day. Factors to consider: The type of project (Touch up, new countertops, polish an existing counter or floor), the size of the area, what type of material are you polishing, and water run off. * Wet/Dry- Water helps the pad plow over the surface easier, it cleans the surface area, controls harmful dust, and I will add longevity to this item. ** Aluminum backing pad great for concrete, and terrazzo floors, areas that are not subject to breaking.

I would not recommend this to anyone. The sanding pads them selves are good and were doing the job, but after 5 min of on and off use the backer pad broke apart and and the Velcro came unglued from the pad and rubber pieces went flying. The actual sanding pad still attached to the Velcro also went flying into the side of my house which damaged my siding. Fortunately I had on eye protection and the plastic pieces that flew toward my face bounced off my goggles and the disk missed my head. Very scary.

The product is not able to perform basic functionality . Discs leave stains on white marble by shedding brown supporting layer of diamond abrasive . Requiring manual polishing on grit sizes above 800. Also at suggested speed 2500 rpm creates surface burns with no applied pressure

Probably ok for light use on home repairs, but for a professional stone worker, they wore out and started coming apart a little quicker than I hoped. Backer pad was ok but like other reviews glue does come apart on velcro. If you notice it and are gentle it lasts longer than the pads tho.

Fits perfectly on my angle grinder and pads have been working great on the concrete. They also sticking well to the wheel assuming you're not running grinder at 12000 rpm. Around 3000 rpm works great

Good pads, used them to wet polish an edge of a quartz countertop. Worked as expected

Polished a lot of granite tile edges and the finish quality was really good

The lower grits, worked great but after limited use the 1500 and 3000 started to come apart, otherwise it would be 4 stars

Top quality product, great selection of grits, and 1/3 the price available locally.
