3M 7100159115 Scotch-brite Roloc Disc 3 Inch Non-woven Ao

Product Description

The 3M 7100159115 is a Scotch-Brite Roloc surface conditioning disc designed for heavy-duty deburring and finishing on metal and fabricated components. Built with a coarse, non-woven abrasive construction, the disc conforms to irregular and contoured surfaces without gouging or undercutting the base material. The disc measures 3 inches in diameter and is rated for operation up to 18000 RPM. It uses the Roloc quick-change attachment system, allowing fast disc swaps during multi-step finishing operations. Licensed tradespeople in metal fabrication, automotive, and maintenance settings rely on this disc for consistent, repeatable surface prep results.

This disc is suited for surface conditioning tasks including deburring, blending, light material removal, and finishing on metal workpieces with flat or contoured profiles. The open-web, non-woven fiber construction resists loading and dissipates heat during use, making it effective for extended finishing runs. It is commonly used in fabrication shops, MRO environments, and production settings where quick disc changes and consistent finish quality are priorities. The aluminum oxide (AO) abrasive mineral provides aggressive cutting action appropriate for ferrous and non-ferrous metals.

Key Features

Compatibility

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

Installation Notes

Installation is performed by pressing the disc onto a Roloc-compatible mandrel and rotating to lock. Ensure the grinder or die grinder is powered off and disconnected from its air or electrical supply before mounting or removing the disc. Do not exceed the 18000 RPM maximum speed rating. Eye protection and appropriate PPE should be worn during operation per applicable workplace safety standards.
