3M 7000047096 Quick Change Disc 3/4 Inch Ao Coarse

Product Description

The 3M 7000047096 is a Standard Abrasives Quick Change Surface Conditioning RC Disc designed for single-step cleaning and finishing on flat workpieces before final coatings or surface treatments are applied. Built on an open-web RC material with aluminum oxide abrasive, it delivers consistent cut rate from first contact through the life of the disc. The RC material breaks down under medium pressure to continuously expose fresh fibers and mineral, maintaining cutting efficiency throughout use. At 3/4 inch in diameter, the disc mounts quickly to compatible quick-change tool systems used in fabrication, light metalwork, and composite finishing applications.

This disc is suited for use on flat surfaces including composites and softer metals such as aluminum. Typical applications include blending, coating removal, light deburring, and surface prep for primers and finish coatings. The load-resistant construction resists clogging from paint residue and corrosion byproducts, making it effective for cleaning and prepping previously coated or corroded workpieces. Fabricators, metalworkers, and finishing technicians working in both shop and field environments will find this disc fits into standard quick-change arbor systems for efficient swapping between discs.

Key Features

• Aluminum oxide on RC open-web material provides good initial and extended cut rate
• RC material breaks down under medium pressure to expose new fibers and mineral for continuous cutting performance
• Load-resistant construction reduces clogging from paint and corrosion debris
• Open web conforms to surface irregularities and minimizes gouging on flat workpieces
• Coarse grade suitable for blending, coating removal, finishing, and light deburring
• Quick-change mounting design speeds disc swapping and improves tool efficiency

Compatibility

Designed for use with compatible quick-change rotary tool systems; intended for flat surface applications on composites and soft metals including aluminum.

Installation Notes

Mounting and disc changes should be performed with the tool powered off and disconnected from its power source. Verify the disc arbor and backing pad are compatible with this disc diameter before mounting. Use appropriate eye protection and respiratory protection when grinding or surface conditioning. Follow applicable workplace safety standards and tool manufacturer guidelines for maximum RPM ratings.
