3M 7010309516 27 Inch Surface Conditioning Disc Coarse

Product Description

The 3M 7010309516 is a non-woven surface conditioning disc engineered for right angle grinder applications. Built from durable open-web fiber construction bonded with aluminum oxide abrasive, this disc is designed for cleaning, blending, deburring, and surface finishing across a range of materials. At 27 inches in diameter, it suits large-surface work where coverage and conformability matter. The coarse grade provides aggressive material removal while the non-woven structure runs cooler than coated abrasives and resists loading during extended operation. Fabricators, metalworkers, and finishing technicians rely on this disc for efficient multi-step surface prep workflows.

This disc is suited for industrial and commercial fabrication environments where surfaces require conditioning prior to coating, welding, or inspection. The conformable construction follows irregular contours and curved profiles without undercutting or damaging the base substrate. Compatible materials include metal, composite, plastics, and other hard surfaces. The hook and loop attachment system allows fast disc changes, making it practical for multi-step finishing sequences where grade changes are frequent.

Key Features

• Non-woven open-web fiber construction conforms to irregular and contoured surfaces
• Aluminum oxide abrasive in a coarse grade for aggressive cleaning and blending
• Runs cooler than coated abrasives and resists loading for prolonged use
• Hook and loop attachment system enables fast disc changes during multi-step finishing
• Suitable for metal, composite, plastics, and other materials without gouging base substrate
• 27 inch diameter provides broad surface coverage for large workpieces

Compatibility

Designed for use with right angle grinders that accept 27 inch hook and loop surface conditioning discs.

Installation Notes

This disc is installed and serviced by fabricators, metalworkers, or industrial finishing technicians. Before mounting, ensure the grinder is fully powered down and disconnected from its power source. Verify the grinder's rated speed meets or exceeds the disc's maximum operating RPM before use. Inspect the hook and loop backing plate for wear before attaching the disc, as a worn interface can cause disc slippage during operation.
