Review: Awesome for polishing rocks - Awesome product the only issue i had was that the bore hole in the middle was slightly smaller then my grinder and i had to drill it out to make it fit but i really enjoy how well the grit has stayed on this disc for as much as i have used it. Def worth it
Review: awesome quality works great - Im a lapidary artist so I use these to go from preform to cab shape then go through the rest of the grits.. this is just after shaping on the 60 ....then I go to 180, 320,600,1200,3000 ,14000 and 50,000 ...this is awesome ...does the work in no time. I highly recommend this disc.
