Surface conditioning disc, 3 in TR

This 3M 05530 disc is a non-woven surface-conditioning abrasive made with aluminum oxide. The very fine grade and open coating resist loading while delivering a consistent finish. A TR quick-change system allows fast swaps on compatible right-angle tools. Maximum operating speed is 18 000 RPM.

Finishing and prep work, not stock removal

Suited for metalworkers and automotive technicians who need light blending, cleaning or final surface preparation before coating. The very fine grade will not remove heavy material, sharp burrs or deep scratches. Buyers needing aggressive stock removal should select a coarse or medium grade disc instead.

18 000 RPM maximum operating speed

The disc is rated for 18 000 RPM; the tool spindle must not exceed this speed. Running the disc faster risks disintegration and injury. Always verify the tool's free speed before mounting and follow the manufacturer's safety guidelines.
