3M 7100142217 Quick Change Disc 3 Inch Ao 18000 Rpm

Product Description

The 3M 7100142217 is a quick change surface conditioning disc designed for single-step cleaning and finishing of workpieces prior to final coatings or finishes. Built on an open RC (resin-bonded conditioning) web with aluminum oxide abrasive, it breaks down under medium pressure to continuously expose fresh fibers and mineral, maintaining cut rate throughout the disc's life. The 3-inch diameter disc mounts at up to 18000 RPM and is load-resistant to minimize clogging from paint, corrosion, and soft metal debris. It is sold individually and intended for use by metalworkers, fabricators, and finishing technicians.

This disc suits flatwork, composite surfaces, and softer metals such as aluminum. Typical applications include blending, coating removal, surface finishing, and light deburring on flat or low-contour parts. The open web construction allows the disc to conform to minor surface irregularities, reducing the risk of gouging. It is available in multiple grades: dark brown for extra coarse, brown for coarse, maroon for medium, and blue for very fine, allowing selection based on surface condition and finish requirement.

Key Features

• Aluminum oxide on RC web material provides consistent initial and extended cut rate
• Load-resistant construction resists clogging from paint, corrosion, and soft metal debris
• Open web conforms to surface irregularities and minimizes gouging
• Suited for blending, coating removal, finishing, and light deburring on flat surfaces
• Quick change mount design allows fast disc swaps without additional fasteners
• Available in extra coarse, coarse, medium, and very fine grades

Compatibility

Designed for use with standard quick change disc tools and mandrels accepting 3-inch surface conditioning discs. Best suited for use on composites and soft metals such as aluminum, as well as general flatwork applications.

Installation Notes

Mounting and removal should be performed with the tool unpowered and disconnected from its air or power source. Verify the tool's rated RPM meets or exceeds 18000 RPM before use, and confirm the mandrel is rated for the disc diameter. Inspect the disc for damage before each use and do not exceed the maximum operating speed marked on the disc or packaging.
