3M 7010328308 Quick-change Disc 200 Grit Diamond 2in Roloc Tr

Product Description

The 3M 7010328308 is a coated abrasive quick-change disc designed for use with Roloc TR (Type III) attaching systems. At 2 inches in diameter, it features a diamond abrasive material with a 200 grit rating and a flexible polyester (J-weight) backing. This disc is engineered for grinding, blending, and finishing applications where a consistent cut rate and surface finish are required. It is rated to a maximum of 25,000 RPM and fits the Series 6234J product line. Licensed trades and production technicians who work with hard or abrasive-resistant materials will find this disc suited to precision surface work.

This disc is intended for use on hard substrates where diamond abrasive provides a performance advantage over conventional aluminum oxide or ceramic grains. Typical applications include deburring, surface preparation, and finish blending on materials such as glass, ceramics, carbide, or hardened metals. The flexible polyester backing allows the disc to conform slightly to irregular surfaces, making it appropriate for contoured workpiece geometry as well as flat stock. It is used in maintenance, repair, and production environments.

Key Features

• Diamond abrasive material for use on hard, abrasive-resistant substrates

Compatibility

Designed for use with Roloc TR (Type III) quick-change disc holders and backup pads. The TR attaching system is not cross-compatible with standard Roloc (Type I) holders; confirm your backup pad is rated for the TR system before use.

Installation Notes

Installation requires a compatible Roloc TR backup pad mounted in a pneumatic or electric right-angle grinder. Ensure the tool is powered off and air supply is disconnected before changing discs. Verify that the tool RPM rating meets or exceeds 25,000 RPM and that the disc is fully seated and locked onto the backup pad before operating. Inspect the disc for damage before each use and do not exceed the rated maximum speed.
