3M 7000119540 Psa Abrasive Disc 500 Grit 5 in 100 Pack

Product Description

The 3M 7000119540 is a pressure-sensitive adhesive (PSA) abrasive disc designed for fine surface finishing and preparation work. Built on a flexible C-weight paper backing, this disc uses aluminum oxide abrasive grain at 500 grit, placing it in the super fine grade range. At 5 inches in diameter, it mounts directly to PSA-compatible backup pads without fasteners. The gold disc color helps operators track wear during use. Rated to 12,000 RPM, it is suitable for use on both orbital and rotary sanders in professional finishing environments. Each package contains 100 discs, and vacuum holes are not included in this configuration.

This disc is used in metal fabrication, woodworking, automotive body finishing, and general surface prep applications where a super fine scratch pattern is required before priming, coating, or polishing. The 500-grit aluminum oxide construction handles final stock removal and surface refinement on bare metal, wood, and composite substrates. The flexible paper backing conforms to slightly contoured surfaces, making it useful for technicians working on panels, cabinetry, and trim components. Professional finishing shops and trade contractors will find the 100-disc pack quantity practical for high-volume work.
