3M 7000120803 Surface Conditioning Disc 7 Inch 6000 Rpm

Product Description

The 3M 7000120803 is a heavy-duty, non-woven surface conditioning disc engineered for aggressive deburring and finishing on metal and contoured surfaces. Measuring 7 inches in diameter and rated to 6000 RPM, this disc uses an aluminum oxide abrasive mineral bonded into an open-web, non-woven fiber construction. The open-web design resists loading and dissipates heat, allowing the disc to run cool and deliver consistent finishes across extended use. A hook and loop attachment system locks the disc securely to compatible backup pads, enabling fast changeovers in multi-step finishing operations. Licensed HVAC techs, fabricators, and metal finishing professionals rely on this disc for edge deburring and surface prep work where conformability to irregular geometry matters.

The 7000120803 is suited for residential and industrial metal fabrication, weld cleanup, and edge deburring on ferrous and non-ferrous metals. Its non-woven fiber construction conforms to curved, contoured, and irregular surfaces without removing base material aggressively or distorting workpiece edges. The hook and loop system makes it a practical choice for multi-step surface conditioning workflows where discs are swapped frequently between grits or abrasive types.

Key Features

• 7 inch diameter non-woven disc rated to 6000 RPM for heavy-duty deburring and finishing
• Aluminum oxide abrasive mineral delivers extra cut and longer service life compared to standard SC and PD surface conditioning discs
• Open-web construction resists loading and runs cool for consistent, repeatable surface finishes
• Conforms to irregular, contoured, and edge geometry without damaging base material
• Hook and loop attachment system enables quick disc changeover in multi-step finishing operations

Compatibility

Designed for use with hook and loop backup pads that accept 7 inch non-woven surface conditioning discs. No specific tool or pad model numbers were stated in the product data.

Installation Notes

Mount only on a backup pad rated for the disc diameter and at or above the 6000 RPM maximum speed rating. Inspect the disc and pad for wear or debris before each use and ensure the hook and loop surfaces seat fully before operating. Always wear appropriate eye and respiratory protection when grinding or finishing metal surfaces. Disconnect or power down the tool before changing discs.
