Mirka Surface Prep Disc 3in 100–120P AO Maroon - 25/Box

Mirka Surface Prep Discs are durable non-woven abrasives designed for controlled cleaning, blending, and finishing on metal surfaces. Ideal for automotive, fabrication, and industrial applications, they provide effective surface conditioning with a finer cut for smoother results.

Made from tough synthetic fibers impregnated with aluminum oxide (AO) abrasive, these discs are optimized for deburring, weld seam refinement, and removal of light paint, rust, and scale. The open structure helps reduce heat buildup while maintaining consistent performance and minimizing surface damage.
