3M 361F Quick-Change Sanding Disc P100

The 3M 22408 disc uses aluminum oxide abrasive on a polyester YF backing with a closed coating. It measures 1 1/2 inches in diameter and attaches via a TR quick-change system. A pack contains 50 blue discs rated for up to 30 000 RPM. They suit metal finishing and surface preparation tasks.

Ideal for metalworkers needing fast grit changes

These discs work well for operators who need rapid disc swaps on right-angle die grinders. They are not suited for buyers who want larger diameters for wide-area sanding. They also do not suit users who require a hook-and-loop attachment instead of the TR system.

P100 grit with 30 000 RPM maximum speed

The P100 grade provides a medium cut for blending and finishing. The 30 000 RPM limit determines the fastest tool speed you can safely use. Exceeding this speed risks disc failure and injury. Always match the disc rating to your grinder's free speed.

Questions about this item

What diameter disc fits the 361F quick-change holder?

The 1-1/2 inch overall diameter matches the TR quick-change system on the 361F series.

How do you attach the TR quick-change disc without cross-threading?

Align the disc tabs with the holder slots, press straight in, then twist clockwise until it locks; forcing it at an angle strips the threads.

When should the P100 aluminum-oxide disc be replaced?

Replace when the blue coating wears through to the brown backing or when cutting speed drops noticeably at speeds up to 30,000 RPM.
