3M 7100359481 Scotch-brite Roloc Hd-dr Disc 3 Inch

Product Description

The 3M 7100359481 is a Scotch-Brite Roloc HD-DR Precision Heavy Duty surface conditioning disc designed for demanding metalworking applications. Built on an open, three-dimensional nonwoven fiber structure, the disc continuously exposes fresh abrasive as it wears, delivering consistent cut and longer service life compared to conventional surface conditioning discs. The 3-inch diameter disc uses 3M Precision-Shaped Grain bonded with resin into Scotch-Brite nonwoven fibers, combining abrasive aggressiveness with the controlled surface finish that heavy-duty refinishing and blending tasks require. It is suited for grinding, deburring, edge breaking, blending, and surface refining operations across a range of metal substrates.

This disc is intended for high-pressure metalworking operations in fabrication shops, aerospace maintenance, HVAC fabrication, and general industrial production environments. It performs on aluminum, mild steel, nickel alloy, stainless steel, and copper. The Roloc attachment system makes it compatible with standard right-angle die grinders and inline grinders equipped with a Roloc-style mandrel, allowing fast disc changes without tools in production or field service settings.

Key Features

• Open three-dimensional nonwoven fiber structure continuously exposes fresh abrasive grain as the disc wears for consistent performance and extended life
• 3M Precision-Shaped Grain improves cut rate and surface finish over traditional surface conditioning abrasives
• Suited for grinding, deburring, edge breaking, blending, and refining on multiple metal types
• Compatible with aluminum, mild steel, nickel alloy, stainless steel, and copper
• Roloc attachment system enables fast, tool-free disc changes on compatible right-angle and inline grinders
• 3-inch diameter for use with standard Roloc mandrel tooling

Compatibility

Designed for use with Roloc-style mandrel grinders and die grinders that accept 3-inch Roloc discs. Compatible with aluminum, mild steel, nickel alloy, stainless steel, and copper workpieces.

Installation Notes

Installation and disc changes should be performed by a qualified operator with the grinder fully powered off and disconnected from its air or electrical supply. Thread the disc onto a compatible Roloc mandrel until it seats firmly before resuming operation. Always verify the grinder speed rating does not exceed the disc speed rating before use, and wear appropriate eye and face protection during operation.
