3M 7000000390 Roloc 361F 2 Inch P180 Abrasive Disc

Product Description

The 3M 7000000390 is a 2-inch Roloc quick-change abrasive disc in the 361F series, designed for grinding, blending, deburring, and finishing on metal surfaces. It features aluminum oxide abrasive grains bonded to a YF-weight polyester cloth backing using a heat-resistant resin system. The quick-change Roloc attachment allows fast, secure disc swaps without tools, reducing downtime during metal fabrication work. Rated to 25,000 RPM, this disc handles medium-pressure applications in both wet and dry conditions. It is suited for use by metal fabricators, welders, pipefitters, and maintenance technicians working on ferrous and non-ferrous metals.

The 361F disc is built for production and maintenance environments where consistent stock removal and finishing quality are required. The aluminum oxide grain cuts fast across a wide range of metals including steel, stainless, and aluminum. The YF-weight polyester backing resists tearing and flex fatigue under medium pressure, making it practical for contoured surfaces, weld seam blending, and edge deburring. Wet or dry compatibility adds versatility when coolant or water is used in the work area.

Key Features

• Roloc quick-change attachment for tool-free disc installation and removal
• Aluminum oxide abrasive grain delivers fast cutting on most metal surfaces
• YF-weight polyester cloth backing supports medium-pressure grinding and finishing

Compatibility

Designed for use with Roloc-compatible disc holders and angle grinders or die grinders that accept 2-inch quick-change abrasive discs.

Installation Notes

Installation and disc changes should be performed by the operator with the grinder powered off and disconnected from the power source. Ensure the Roloc holder is rated for the disc diameter and RPM before mounting. Operators should wear appropriate PPE including face shields and gloves when performing grinding or deburring tasks. Follow applicable ANSI B7.1 and OSHA standards for abrasive wheel use and maximum operating speed compliance.
