Quick-Change Fiber Discs

The 3M 27404 Cubitron II 982C discs are 5-inch ceramic-coated fiber abrasives designed for aggressive material removal on metal surfaces. Each disc carries a 36 grit rating and uses a TN quick-change connector for fast tool swaps. The package contains 25 discs rated for a maximum operating speed of 12,000 RPM.

Extra-Coarse Metal Grinding

These maroon discs suit weld grinding, heavy deburring and scale removal where an extra-coarse cut is required. The closed-coat ceramic grain resists loading and tearing during high-pressure work. They are not intended for fine finishing, wood sanding or applications needing a finer grit or different backing material.

Compatible Tool Setup

The 5/8 in.-11 TN hub fits angle grinders and right-angle sanders that accept quick-change fiber discs at 12,000 RPM or higher. The YY-weight fiber backing provides stiffness for flat grinding while the 25-disc pack reduces change-over frequency during extended jobs.

Questions about this item

What backing pad or sander is needed to run a 5 inch 36 grit disc with a 5/8-11 TN connector?

A sander or backing pad that accepts a 5/8 In. -11 thread and is rated for at least 12,000 RPM will hold the disc securely.

Will these 36 grit ceramic fiber discs load quickly on a variable-speed grinder that I already own?

The closed-coat ceramic grain resists loading, and the 12,000 RPM maximum speed matches common 5 inch grinders when run at full throttle.

How can I confirm the 3M 27404 discs are cutting at the rated 12,000 RPM once installed?

The maroon 982C marking on each disc identifies the grade; steady, vibration-free cutting at full tool speed shows the disc is operating within its 12,000 RPM limit.
