3M 7000045103 Quick-change Disc 120 Grit 1.5in Aluminum Oxide

Product Description

The 3M 7000045103 is a quick-change coated abrasive disc designed for use with Roloc TR (Type R) attachment systems. It features a 1.5-inch diameter, 120-grit aluminum oxide abrasive on a polyester cloth backing rated YF weight. The Series 361F disc is engineered for fine finishing and surface conditioning tasks at speeds up to 30,000 RPM. The brown disc with white button mounts and releases quickly without tools, making it a practical choice for technicians who change discs frequently during metalworking, deburring, or surface prep operations.

This disc is suited for metal fabrication, maintenance and repair, and light material removal on ferrous and non-ferrous surfaces. The 1.5-inch format fits compact angle grinders and die grinders commonly used in confined areas or tight geometries. The aluminum oxide grain is appropriate for general-purpose grinding and finishing where a consistent fine scratch pattern is required. It is commonly used by fabricators, maintenance mechanics, and production technicians working on steel, aluminum, and similar materials.

Inspect the disc for damage before each use and replace immediately if cuts, tears, or delamination are present.
