12 in Plain Back Silicon Carbide (SiC) Grinding Paper

12 in plain back silicon carbide (SiC) grinding paper discs are intended for metallographic applications where adhesive backing is not required. The durable plain paper backing is well suited for use with mechanical clamping systems, magnetic fixtures, or manual setups where disc repositioning or reuse is preferred.

This collection includes 12 in (300 mm) diameter SiC grinding paper across a complete range of grit sizes. Grits from 60/P60 through 600/P1200 are electrostatically coated to deliver aggressive, uniform material removal during coarse and intermediate grinding. Fine grits from 800/P2400 through 1200/P4000 are slurry coated, providing improved abrasive retention and enhanced control for precision grinding prior to polishing.

Plain back 12 in SiC grinding paper is commonly used on floor-standing and automated grinding systems for the preparation of steels, aluminum alloys, copper alloys, and cast materials. These discs are compatible with most standard 12 in platens and integrate easily into controlled metallographic preparation workflows.
