3M 8 Inch 120 Grit Electrostatic Diamond Disk

3M's 675L Electrostatic Diamond Disks are a paper backed disk with diamonds adhered to the surface and electrostatically charged during the curing period. This enables the diamonds to "stand up" on the surface of the pad and flow under the glass as you grind giving you a fantastic surface appearance and a controlled grinding experience. Perfect for small surface areas where control is more important than stock removal. These disks will not perform as well on larger surface areas.
