3M 361F Quick Change Disc

The 3M 361F Quick Change Disc is a coated abrasive disc designed for use with sanders. It features an aluminum oxide abrasive on a polyester backing with a closed coating. The TR quick-change system allows fast disc swaps during sanding tasks.

Suited for medium-grade surface preparation

These discs suit operators who need a medium-grade abrasive for general surface preparation on metal or wood. The 3-inch diameter fits compatible quick-change holders. Buyers needing a finer or coarser grit, or a different attachment style, should look at other options.

Pack of fifty discs for extended use

A package quantity of fifty discs reduces the frequency of reordering for high-volume workshops. The heat-resistant properties help maintain performance during sustained operation. The white colour coding aids quick visual identification among other abrasive grades.

Questions about this item

What backing-pad thread type does the 3M 22406 361F disc require to mount on my sander?

The disc uses a TR quick-change system, so it locks onto any TR-compatible backing pad without tools.

Will these P120 discs load up quickly when I run them at 20,000 RPM on a rotary polisher?

The closed-coat aluminum-oxide surface on XF-weight polyester resists heat buildup, reducing loading at the rated 20,000 RPM maximum speed.

How can I confirm the 50-disc pack is cutting consistently after I start the job?

A uniform white scratch pattern across the workpiece and steady material removal without glazing show the 361F series is performing as designed.
