3M 7000047075 Surface Conditioning Disc 4.5 in Coarse

Product Description

The 3M 7000047075 is a Surface Conditioning RC Disc designed for deburring, blending, cleaning, and finishing operations on composites and soft metals. It uses an Aluminum Oxide abrasive on a reinforced composite (RC) backing that balances edge durability with enough flexibility to conform to workpiece surfaces. At a rated speed of 8000 RPM and a 4.5-inch diameter, this disc delivers consistent initial cut and maintains that cut rate across extended use cycles. It attaches via a Hook and Loop system, making pad changes fast during production or service work.

This disc is suited for general-purpose surface conditioning tasks in fabrication, maintenance, and finishing environments. It performs best on flat surfaces of composites or soft metals where light deburring, blending, and coating removal are required. The coarse grade makes it effective for aggressive cleaning and surface prep before coating or bonding. It is sold individually and is appropriate for both shop and field use wherever a right-angle grinder or disc pad holder is part of the workflow.

Key Features

• Aluminum Oxide abrasive on RC backing provides good initial and extended cut rate
• High edge durability with flexible construction for flat and near-flat surfaces
• Rated to 8000 RPM for use with standard right-angle grinders and disc tools
• Hook and Loop attachment system for fast disc changes
• Coarse grade suited for blending, coating removal, cleaning, and light deburring
• Most efficient on composites and soft metals under average operating pressure

Compatibility

Designed for use with Hook and Loop disc pad holders compatible with 4.5-inch surface conditioning discs on right-angle grinders and similar rotary tools rated to handle 8000 RPM.

Installation Notes

This disc is installed by a technician or fabricator onto a compatible Hook and Loop backing pad mounted to a right-angle grinder. Verify that the grinder free-speed rating meets or exceeds 8000 RPM before mounting the disc. Inspect the disc for tears or damage before each use and do not exceed the rated RPM. Wear appropriate eye protection and follow applicable workplace safety standards when operating abrasive discs at speed.
