3M 7010518344 Psa Abrasive Disc 15 in 50 Grit

Product Description

The 3M 7010518344 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on large-surface grinding and finishing applications. Built on an X-weight cloth backing, the disc delivers durability and flexibility under load. The abrasive mineral is aluminum oxide in a coarse 50-grit grade, making it well suited for stock removal, weld blending, and surface preparation on metal, wood, and composites. At 15 inches in diameter, this disc is sized for large-format random orbital sanders used in production and industrial environments. Licensed tradespeople and production floor operators in metalworking, fabrication, and woodworking shops are the primary installers and users of this disc.

The 3M 7010518344 fits into workflows that demand consistent cut rate across wide surface areas. Its PSA mount system allows quick disc changes on compatible 15-inch random orbital sanders without mechanical fasteners. The coarse 50-grit cut is appropriate for initial surface prep, paint and coating removal, and leveling uneven weld seams before progressing to finer finishing steps. No vacuum holes are included, which suits solid-platen backer configurations common in high-production settings.

Key Features

• 15-inch diameter suits large-format random orbital sanding machines
• 50-grit aluminum oxide provides aggressive coarse-grade stock removal
• X-weight cloth backing resists tearing and flexes to contoured surfaces
• PSA mount enables fast, tool-free disc changes on compatible machines
• No vacuum holes — compatible with solid-platen backer pad configurations
• Series 348D construction for consistent grit distribution and cut life

Compatibility

Designed for use with random orbital sanders that accept 15-inch PSA-mount abrasive discs. No vacuum hole pattern is present, so a solid backing pad is required.

Installation Notes

This disc is installed by production machine operators or trade professionals maintaining sanding equipment. Before mounting, ensure the sanding machine is powered off and the backing pad surface is clean and free of adhesive residue from the previous disc. Peel the release liner and align the disc carefully to the center of the backing pad before pressing firmly to seat the adhesive evenly. Do not exceed the maximum RPM rating of the machine for which the disc is intended.
