3M 361F Quick-Change Sanding Discs

These 3M 361F discs use aluminum-oxide grain on a polyester YF-weight backing for coarse material removal. The TR quick-change system locks each 2-inch disc onto a compatible backup pad in seconds. Supplied in a pack of 50, they suit metal-fabrication shops and automotive refinishing tasks that demand consistent cut rate.

Check backup pad and tool speed

Verify that your right-angle or die grinder accepts TR-style 2-inch holders and is rated for at least 25,000 RPM maximum operating speed. The closed-coat construction loads less on soft metals, but the coarse 80 grit will leave visible scratch patterns on fine-finish workpieces.

Heat-resistant bond sustains cut rate

The heat-resistant resin bond reduces grain breakdown during extended grinding passes on steel or aluminium. Closed coating keeps swarf from clogging the surface, so the disc maintains aggressive stock removal longer than open-coat alternatives under continuous pressure.

Questions about this item

What discs are included and does the pack contain a holder?

The box contains fifty 2-inch quick-change sanding discs, grade 80 grit, aluminum oxide on polyester backing. A TR holder is not included and must be purchased separately.

When should I choose the 80 grit 361F over other grades?

Choose the 80 grit 361F for coarse material removal and heavy stock removal on metal; finer grades are for finishing, coarser grades for faster cutting.

What does the 25,000 RPM rating mean on my tool?

The 25,000 RPM figure is the maximum safe speed for the disc; your sander or die grinder must not exceed this speed when the disc is mounted.
