3M 7010308442 Roloc 361F 4 Inch 60 Grit Abrasive Disc

Product Description

The 3M 7010308442 is a Roloc quick-change coated abrasive disc designed for grinding, blending, deburring, and finishing on all metals. The disc uses aluminum oxide abrasive grains bonded to a YF-weight polyester cloth backing with a heat-resistant resin system, making it suitable for both wet and dry applications. At 4 inches in diameter and rated to 15,000 RPM, it is built for medium-pressure work where consistent material removal and durability are required. Metalworkers, fabricators, and maintenance technicians commonly use this disc with angle grinders and die grinders equipped with a Roloc-compatible mandrel.

This disc is suited for use on ferrous and non-ferrous metals in fabrication, maintenance, and production environments. The 60-grit aluminum oxide grain provides fast cutting action appropriate for stock removal, weld blending, and surface conditioning tasks. The YF-weight polyester backing resists tearing under the lateral loads typical in hand-held grinding operations. The heat-resistant resin bond maintains abrasive retention during extended use and in wet-process applications where coolant or water is present.

Key Features

• Roloc quick-change attachment system allows fast, secure disc installation and removal without tools
• Aluminum oxide abrasive grains deliver fast cutting action across a wide range of metals
• YF-weight polyester cloth backing supports medium-pressure grinding and resists tearing
• Heat-resistant resin bond maintains adhesion under pressure, elevated temperatures, and wet conditions
• Rated to 15,000 RPM for compatibility with standard angle and die grinders
• Suitable for wet or dry use, offering flexibility in various shop and field environments

Compatibility

Designed for use with Roloc-compatible mandrels and grinders accepting 4-inch quick-change abrasive discs. Confirm mandrel RPM rating meets or exceeds 15,000 RPM before use.

Installation Notes

Installation and removal require a Roloc mandrel attached to a grinder with an appropriate RPM rating. Verify the grinder is powered off and fully stopped before changing discs. Inspect the disc for damage before mounting and do not use discs that show cracks, tears, or delamination. Follow applicable ANSI B7 abrasive safety standards and wear appropriate PPE including eye and face protection.
