3M 7100086776 Scotch-brite Roloc Disc 4 Inch Medium Ao

Product Description

The 3M 7100086776 is a Scotch-Brite Roloc High Strength abrasive disc designed for deburring, surface cleaning, and satin finish work on metal and similar substrates. Built on an open-web nylon construction with aluminum oxide abrasive mineral, this 4-inch diameter disc runs at up to 9000 RPM and attaches via the Roloc twist-on backing system for fast changeover between finishing steps. The open-web structure resists loading and dissipates heat, helping maintain consistent cut and finish quality across multiple passes. Weighing approximately 0.05 pounds, the disc is lightweight and balanced for extended use with compatible right-angle grinders and disc tools.

This disc is suited for metalworking applications in fabrication shops, HVAC sheet metal work, plumbing rough-in, and general industrial maintenance. It performs well on flat surfaces as well as contoured or irregular geometry without gouging or altering base material dimensions. The medium grade makes it appropriate for moderate stock removal and transitional finishing steps where a finer surface profile is required before final finishing or coating. It is sold individually and intended for professional trade use.

Key Features

• Open-web aluminum oxide construction resists loading and runs cool for consistent finishes
• Conforms to flat and irregular surfaces without damaging base material dimensions
• Roloc twist-on attachment system allows quick disc changes during multi-step finishing processes
• Rated to 9000 RPM for use with standard right-angle disc grinders
• Suitable for deburring, cleaning, and satin finish applications on metal substrates

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc holders that accept 4-inch twist-on abrasive discs.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or air supply disconnected. Verify the tool spindle speed rating meets or exceeds the disc maximum of 9000 RPM before mounting. Inspect the disc for damage before each use and do not use damaged or delaminated discs. Always wear appropriate eye and face protection when operating abrasive disc tools.
