361F 2 in Quick-Change Sanding Discs

3M 361F aluminium-oxide discs use a TS quick-change system for fast swaps on right-angle die grinders. The 2 in diameter and closed-coat construction suit coarse stock removal on metal surfaces. Each pack supplies fifty discs for extended shop use.

TS Quick-Change Interface Limits

The TS quick-change button locks the disc to compatible backup pads rated for 25 000 RPM maximum operating speed. Exceeding that speed or using a non-TS pad risks disc separation. The polyester YF-weight backing resists heat but does not eliminate thermal limits during prolonged heavy grinding.

Upgrade From Slower-Cut or Non-Quick-Change Media

These coarse 80-grit discs replace slower-cutting finer grits or adhesive-backed discs that require tool downtime for changes. The jump is worth it when rapid material removal and minimal changeover time outweigh the need for a finer finish.

Questions about this item

Should I choose the 80 grit or a finer grade?

The 80 grit provides a coarse cut for rapid stock removal; select a higher grit number only when you need a smoother finish after the initial sanding stage.

How does the 25,000 RPM rating affect daily use?

It sets the maximum safe spindle speed; run your tool at or below this limit to avoid disc failure and maintain consistent cutting performance.

What does the TS quick-change system mean for disc swaps?

The TS (Type S) metal button locks into compatible back-up pads, letting you twist discs on and off in seconds without tools.
