15 Packs 4 inch Diamond Polishing Pads with 5/8’’-11 Backer Pad,11 Pcs Wet/Dry Diamond Sanding Pads 50-8000 Grit Pads for Drill Grinder Rock Polisher Granite Marble Stone Concrete Tile Tools (15)

The pads worked good to polish natural stone. The pads were easy to change with the velcro backing. Held up well. Would recommend.

Worked great but only got about 8' sanded on the coursest pads before they were worn flat.

The disks are a great value and are great for the projects im working on the sheer thickness of the pads. Ty

Backer pad is definitely not 5/8” 11 as advertised. I sent for my return and replacement but I was shipped the same wrong item. I did end up buying an adapter, after I got it attached to the grinder it did work well but just to be warned you will need to buy an adapter as expensive as the disks. Very disappointing.

Just what Inneeded to refinish my marble table top. Worked great and a very good price

Good price, worked as expected, with no surprises. Would buy again.

Broke first day, pads are ok they don’t Handel 2000rpm’s at all they began to melt. Fast delivery I just need something stronger.

Was not 5/8 -11 threads on backer, appears to maybe be 3/8
