3M 7010328488 Roloc 361F Disc 3 Inch P320 Grit Ao

Product Description

The 3M 7010328488 is a Roloc quick-change abrasive disc in the 361F series, designed for grinding, blending, deburring, and finishing on all metals. The disc uses fast-cutting aluminum oxide abrasive grains bonded to a YF-weight polyester cloth backing with heat-resistant resin. At 3 inches in diameter and P320 grit, it delivers fine finishing performance in both wet and dry applications. The quick-change Roloc attachment system allows for rapid disc swaps without tools, reducing downtime on the floor. Licensed tradespeople and fabricators working on metal surfaces install this disc using a compatible Roloc mandrel on die grinders and similar rotary tools.

This disc is suited for medium-pressure finishing and blending tasks on ferrous and non-ferrous metals in light fabrication, automotive body work, weld seam cleanup, and general metalworking environments. The P320 grit rating targets fine surface prep and finishing passes rather than aggressive stock removal. It performs consistently in both wet and dry conditions, making it adaptable to shop environments where coolant or water is used during metalworking operations.

Key Features

• Roloc quick-change attachment for fast, secure disc installation and removal without tools
• Aluminum oxide abrasive grains provide fast cutting on a wide range of metal surfaces
• YF-weight polyester cloth backing supports medium-pressure wet and dry applications
• Heat-resistant resin bond maintains abrasive adhesion under pressure, heat, and moisture
• P320 fine grit for blending, deburring, and finishing passes on metal
• Rated to 20000 RPM for compatibility with standard die grinder speeds

Compatibility

Designed for use with compatible Roloc mandrels and die grinders that accept 3-inch quick-change abrasive discs. Suitable for use on all metals in wet or dry grinding and finishing applications.

Installation Notes

Installation is performed by metalworking and fabrication professionals using a Roloc-compatible mandrel mounted in a die grinder or right-angle grinder. Confirm the tool RPM rating meets or exceeds the disc maximum of 20000 RPM before mounting. Power down and disconnect the tool from the air supply or electrical source before changing discs. Do not exceed the rated maximum RPM and inspect the disc for damage before each use.
