3M 7000046112 Scotch-brite Roloc Se-dr Disc 3 Inch Medium

Product Description

The 3M 7000046112 is a Scotch-Brite Roloc SE-DR Surface Conditioning Disc designed for heavy-duty deburring and surface finishing on metal workpieces. Built from a coarse, non-woven aluminum oxide fiber construction, the disc conforms to irregular and contoured surfaces without gouging the base material. The Roloc quick-change attachment system locks onto compatible right-angle grinders and die grinders, allowing fast disc swaps during multi-step finishing operations. At 3 inches in diameter with a medium grade, this disc suits production-level metalworking environments where consistent surface finish and controlled material removal are both required.

This disc is used in fabrication shops, maintenance facilities, and light manufacturing environments for deburring, blending, and surface conditioning on ferrous and non-ferrous metals. The open-web non-woven construction resists loading and runs cooler than coated abrasives, which helps maintain finish consistency across longer work cycles. It is typically installed and operated by machinists, fabricators, pipefitters, and maintenance technicians working with angle grinders or die grinders equipped with Roloc-compatible mandrels.

Key Features

• Coarse non-woven aluminum oxide construction aggressively deburrs and blends surfaces
• Open-web fiber design resists loading and dissipates heat for longer disc life and consistent results
• Conformable disc contours to irregular and curved workpiece geometries without undercutting or gouging
• Roloc quick-change backing allows rapid disc changes during multi-step finishing processes
• Medium grade balances aggressive cutting with controlled surface conditioning

Compatibility

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

Installation Notes

Installation and operation should be performed by trained personnel familiar with abrasive power tool safety. Ensure the grinder or die grinder is powered off and unplugged before mounting or removing the disc. Thread the disc onto a compatible Roloc mandrel until it seats securely before starting the tool. Follow all applicable ANSI B7 abrasive safety standards and the tool manufacturer guidelines for maximum RPM ratings.
