3M 7010309372 Surface Conditioning Disc 3 Inch Coarse

Product Description

The 3M 7010309372 is a coarse-grade, non-woven surface conditioning disc designed for heavy-duty deburring, blending, and finishing on metal and fabricated surfaces. At 3 inches in diameter, the disc uses an aluminum oxide abrasive mineral bonded into an open-web non-woven fiber construction. The Roloc quick-change backing system allows fast, tool-free disc swaps during multi-step finishing operations. Licensed trades and fabrication professionals working with ferrous and non-ferrous metals will find this disc suited for aggressive material removal without gouging the base substrate.

This disc is used in industrial maintenance, metal fabrication, and surface prep applications where controlled deburring and finishing are required. The conformable non-woven construction follows irregular contours and curved surfaces, making it practical for weld cleanup, edge blending, and surface conditioning on components with complex geometry. It is a single-piece disc sized for use with Roloc-compatible right-angle tools and die grinders.

Key Features

• Coarse aluminum oxide abrasive for aggressive deburring and heavy surface conditioning
• Open-web non-woven construction resists loading and dissipates heat to maintain consistent cutting action
• Conformable fiber body follows contoured and irregular surfaces without undercutting or gouging the base material
• Roloc quick-change attachment enables fast disc removal and replacement during multi-step finishing sequences
• 3 inch diameter fits standard Roloc-compatible right-angle grinders and die grinders

Compatibility

Designed for use with Roloc-compatible quick-change right-angle grinders and die grinders that accept 3 inch snap-on disc attachments.

Installation Notes

Installation and disc changes should be performed with the tool powered down and disconnected from the air or electrical supply. Ensure the Roloc mandrel is clean and undamaged before attaching the disc. Eye protection and appropriate PPE are required when operating abrasive discs. Follow the tool manufacturer's maximum RPM rating and verify it meets or exceeds the disc's rated speed before use.
