3M 7000119539 Abrasive Disc 5 Inch 220 Grit 100 Pack

Product Description

The 3M 7000119539 is a 5-inch aluminum oxide abrasive disc designed for surface preparation, finishing, and material removal on wood, metal, and composite surfaces. Part of the 236U series, these discs feature a C-weight paper backing that balances flexibility with durability, making them well suited for contour sanding and finish work. At 220 grit, they fall in the very fine grade range, ideal for final sanding passes, scuff sanding, and prep before coating or finishing. The flexible backing conforms to irregular surfaces, reducing the risk of gouging on softer substrates. Each package contains 100 discs.

These discs are used across a wide range of trade and industrial applications, including millwork, cabinetry, drywall feathering, metal prep, and automotive bodywork finishing. The gold disc color aids in visual wear monitoring so operators can gauge disc life at a glance. With a maximum rated speed of 12,000 RPM, these discs are compatible with standard 5-inch random orbital and DA sanders used in shop and field environments. They are sold in a 100-disc pack, making them practical for high-volume production use or shop stock.
