Mirka MIR-17-101-320 Silicon Carbide 320-Grit 9x11 Finishing Sheet

The Mirka MIR-17-101-320 is a 320-grit silicon carbide finishing sheet measuring 9 inches x 11 inches, designed for fine stock removal, surface preparation, and precision finishing work. Part of Mirka's trusted line of coated abrasives, this sheet is engineered for dry sanding applications where a consistent, uniform scratch pattern and smooth final finish are essential.

Silicon carbide grain provides sharp, fast-cutting action ideal for finishing harder surfaces, while the stearate coating helps resist loading and clogging during use — extending sheet life and maintaining cutting efficiency. The flexible paper backing conforms to contours and flat surfaces alike, making it suitable for both hand sanding and use with orbital or finishing sanders.
