3M 7010308439 Roloc 361F Abrasive Disc P120 1.5 in

Product Description

The 3M 7010308439 is a Roloc quick-change abrasive disc in the 361F series, designed for grinding, blending, deburring, and finishing on ferrous and non-ferrous metals. The disc uses fast-cutting aluminum oxide abrasive grains bonded to a YF-weight polyester cloth backing with a heat-resistant resin. At 1.5 inches in diameter and P120 grit, it is sized for detail work and surface prep in tight areas. The quick-change Roloc attachment locks and releases without tools, reducing downtime during disc changes. Suitable for both wet and dry applications.

This disc is used in metal fabrication, weld blending, and finishing operations where consistent material removal at medium pressure is required. The YF-weight polyester backing resists tearing under sustained use and handles heat buildup common in grinding and deburring tasks. It is typically installed and operated by metalworkers, machinists, fabricators, and maintenance technicians working with angle grinders or die grinders fitted with a compatible Roloc mandrel.

Key Features

• Roloc quick-change attachment allows fast, secure disc installation and removal without tools
• Aluminum oxide abrasive grains provide fast cutting action on steel, stainless, and non-ferrous metals
• YF-weight polyester backing supports medium-pressure grinding and blending
• Heat-resistant resin bond maintains abrasive adhesion under pressure, heat, and water exposure
• Rated for both wet and dry use
• P120 grit suits blending, light deburring, and pre-finishing surface prep

Compatibility

Designed for use with Roloc-compatible mandrels and grinder attachments. Requires a matching quick-change mandrel; not compatible with standard threaded or pressure-sensitive adhesive backing systems.

Installation Notes

Installation is performed by threading the disc onto a Roloc-compatible mandrel attached to a pneumatic or electric die grinder or angle grinder. Power down and disconnect the tool from its air or electrical supply before mounting or removing the disc. Inspect the mandrel and disc for damage before each use. Follow applicable ANSI B11 or shop safety standards for abrasive wheel use, including appropriate RPM rating verification.
