3M 7010330621 Quick Change Disc 1.5 in Ao 20000 Rpm

Product Description

The 3M 7010330621 is a quick change surface conditioning disc designed for one-step workpiece preparation ahead of final finishes and coatings. Built on a non-woven, resin-reinforced open web construction, it delivers consistent cut rates on ferrous and non-ferrous metals as well as composites. The disc is load-resistant, making it well suited for aluminum and other soft metals where clogging is a common problem. At 1.5 inches in diameter and rated to 20000 RPM, it fits standard quick change mandrels used across grinding and finishing operations in fabrication, maintenance, and light industrial settings. Licensed metalworkers and fabricators are the primary installers and users of this product.

This disc is used for moderate industrial surface conditioning tasks including cleaning, deburring, and prep work on flat surfaces and some edge work. Its flexible, pliable web removes burrs and surface contaminants without gouging the base material. The open web structure resists loading, making it a reliable choice when working on aluminum, soft alloys, and composites where conventional abrasive discs tend to fill and glaze. It performs consistently across ferrous metals as well.

• Suitable for flat surface prep and moderate edgework ahead of coatings and final finishes

Compatibility

Designed for use with standard quick change disc mandrels compatible with 1.5-inch diameter surface conditioning discs in grinding and finishing tool applications.

Installation Notes

Mounting and changing of quick change discs should be performed with the tool powered off and disconnected from its power source. Verify the mandrel and tool RPM rating meets or exceeds 20000 RPM before mounting this disc. Inspect the disc for damage before each use and do not use a disc that is torn or shows signs of delamination. Follow applicable workplace safety standards and tool manufacturer guidelines when operating grinding and finishing equipment.
