3M 7000000380 Roloc 361F Coated Disc 1 Inch 80 Grit

Product Description

The 3M 7000000380 is a Roloc quick-change coated abrasive disc in the 361F series, designed for grinding, blending, deburring, and finishing operations on metal surfaces. At 1 inch in diameter and 80 grit, it uses fast-cutting aluminum oxide abrasive grains bonded to a YF-weight polyester cloth backing with a heat-resistant resin system. The result is a disc that holds up under sustained pressure and elevated temperatures while remaining suitable for both wet and dry use. Fabricators, welders, and metal finishing technicians typically reach for this disc when they need consistent stock removal in tight or confined areas where larger discs cannot reach.

This disc is suited for use on a wide range of metals in both light industrial and production environments. The 1-inch format makes it effective for precision deburring, edge blending, and surface finishing in confined weld joints, tubing ends, and small-bore work. The Roloc quick-change system allows fast disc swaps without tools, reducing downtime during repetitive operations. Recommended operating speed is up to 30,000 rpm, making it compatible with standard die grinders and right-angle tools rated for that speed.

Key Features

• Roloc quick-change attachment for fast, tool-free disc installation and removal
• Aluminum oxide abrasive grains deliver fast cutting action on steel, stainless, and non-ferrous metals
• YF-weight polyester cloth backing supports medium-pressure applications with consistent performance
• Heat-resistant resin bond maintains abrasive adhesion under pressure, heat, and moisture
• Compatible with wet and dry operating conditions
• Maximum operating speed of 30,000 rpm suits standard high-speed die grinders

Compatibility

Designed for use with Roloc quick-change compatible die grinders and right-angle tools rated to a minimum of 30,000 rpm.

Installation Notes

Installation and removal require a Roloc-compatible mandrel or holder. Verify the tool spindle speed rating does not exceed the disc maximum of 30,000 rpm before mounting. Inspect the disc for damage before each use and do not use a disc that appears torn, cracked, or delaminated. Wear appropriate eye and face protection per applicable ANSI and OSHA standards when operating any abrasive disc.
