3M 7100066673 Roloc 361F Disc 1.5 Inch P240 Aluminum Oxide

Product Description

The 3M 7100066673 is a Roloc quick-change abrasive disc in the 361F series, designed for grinding, blending, deburring, and finishing on metal surfaces. The disc measures 1.5 inches in diameter and carries a P240 grit rating, placing it in the fine finishing range. Fast-cutting aluminum oxide grains are bonded to a YF-weight polyester cloth backing using a heat-resistant resin system. This construction supports both wet and dry use and holds up under medium-pressure applications. Metalworkers, fabricators, and finishing technicians working on steel, aluminum, and non-ferrous metals are the primary users of this disc.

The 361F disc is suited for light metal finishing operations where a consistent scratch pattern and reliable grain adhesion are required. Its 1.5-inch diameter fits compact Roloc-compatible right-angle grinders and die grinders used in tight workspaces or on contoured surfaces. Applications include weld blending, edge deburring, and surface prep before coating or inspection. The quick-change Roloc attachment system allows fast disc swaps without tools, reducing downtime during production or repair operations.
