8″ Plain Back Silicon Carbide Grinding Paper | SiC Discs

8″ plain backing silicon carbide (SiC) grinding paper discs provide consistent material removal and reliable surface finish for metallographic sample preparation when adhesive backing is not required. With a durable plain paper backing, these discs are ideal for use in manual grinding setups, fixtures, or clamping systems where adhesive attachment is impractical or unnecessary.

This collection includes 8″ (200 mm) diameter SiC grinding paper in a complete grit range. Grits from 60/P60 through 600/P1200 are electrostatically coated to deliver aggressive cutting and uniform scratch patterns during coarse and intermediate grinding. Fine grits from 800/P2400 through 1200/P4000 are slurry coated, offering improved abrasive retention and enhanced control for precision grinding prior to polishing.

Plain backing SiC grinding papers are commonly used on laboratory platens with mechanical clamps or holders and are suitable for steels, aluminum alloys, copper alloys, and cast materials.
