Quick-Change Disc for Sanding Applications

The 3M 11412 361F disc uses aluminum oxide abrasive on a polyester backing rated YF weight. It is designed for extra-coarse material removal with a grit 36 surface and closed coating coverage. The brown discs measure one inch in diameter and attach via a TR quick-change system. Each pack contains fifty discs for high-volume sanding tasks.

Compatibility Check Before Ordering

Verify that your sander or rotary tool accepts TR quick-change attachments and can run safely at or below 25, 000 RPM. Confirm the tool’s spindle or mandrel matches the one-inch disc size and that the machine is rated for coated abrasive discs. Ensure your workpiece and application suit an extra-coarse grit 36 abrasive before purchasing.

Durability and Daily Use Implications

The polyester backing with YF weight resists heat buildup during aggressive sanding, while the closed coating reduces loading on soft materials. TR quick-change mounting lets operators swap discs in seconds without tools, minimising downtime on repetitive jobs. The one-inch diameter targets tight areas, and the fifty-disc pack supports extended production runs without frequent reordering.

Questions about this item

What comes in the box and do I need to buy a holder or mandrel separately?

The package contains 50 brown 361F quick-change discs, 1 inch diameter, 36 grit aluminium-oxide on YF-weight polyester backing; a compatible TR quick-change holder or mandrel is not included and must be purchased separately.

Which grit grade should I choose for heavy stock removal versus finishing?

These discs are 36 grit, extra-coarse, designed for aggressive material removal; select a higher grit number from the 361F range for finer finishing steps.

What does the 25,000 RPM rating mean when the disc is mounted on my tool?

25,000 RPM is the maximum safe operating speed; run the disc at or below this speed on a TR quick-change holder to avoid overheating and premature wear.
