3M 7100042003 Abrasive Refining Disc 3 Inch Silicon Carbide

Product Description

The 3M 7100042003 is a silicon carbide abrasive refining disc engineered for paint finishing and surface preparation work. Measuring 3 inches in diameter and rated to 12000 RPM, this disc cuts fast through sand scratches left behind by 1200 and 1500 grade paint leveling steps. The nonwoven web construction resists loading, extending usable disc life. It is a common tool for auto body technicians and surface finishing professionals handling medium to large area refining and repair tasks.

This disc is suited for refining and repair work on painted panels, clear coat, primer, gel coat, and bare metal surfaces. Its flat abrasive face removes scratches uniformly across larger surface areas. The disc can be run wet or dry, making it adaptable to a pre-buff dry pass or a standard wet refining step. It fits residential and commercial auto body shop applications where consistent scratch removal before buffing is required.
