3M 7100070473 Roloc 361F Disc 3 Inch P100 Grit Ao

Product Description

The 3M 7100070473 is a 3-inch Roloc quick-change abrasive disc designed for grinding, blending, deburring, and finishing operations on all metal surfaces. Built on a YF-weight polyester cloth backing, the disc uses fast-cutting aluminum oxide abrasive grains bonded with a heat-resistant resin system that holds up under pressure, elevated temperatures, and wet conditions. Rated to 20000 RPM, the disc handles medium-pressure applications without glazing or breakdown. It is suited for use with compatible Roloc-style quick-change disc holders and right-angle grinders used by fabricators, pipefitters, and metal finishing technicians.

This disc is intended for metal surface preparation and finishing in fabrication shops, maintenance facilities, and light industrial environments. At P100 grit, it sits in the medium-fine range, making it appropriate for blending weld seams, removing light burrs, and preparing surfaces for coating. The aluminum oxide grain is durable enough for ferrous and non-ferrous metals. The disc supports both wet and dry grinding, giving technicians flexibility in controlled shop environments or in-field service situations.

Key Features

• Roloc quick-change attachment allows fast, secure disc installation and removal without tools

• Suitable for wet or dry applications

Compatibility

Designed for use with Roloc-style quick-change disc holders and compatible right-angle grinders or die grinders that accept 3-inch quick-change abrasive discs.

Installation Notes

Installation requires a compatible Roloc-style disc holder or mandrel mounted to a right-angle grinder or die grinder. Verify the tool RPM rating meets or exceeds the disc rating before use, and do not exceed 20000 RPM. Ensure the disc is fully seated and locked onto the holder before powering the tool. Wear appropriate PPE including eye and face protection whenever operating abrasive discs.
