Quick-Change Sanding Discs

3M 51033 361F Quick Change Discs use a TS quick-change system for fast disc swaps on compatible sanders. The 3-inch aluminum oxide discs come in a pack of 50 for high-volume material removal.

Sustained Load Behaviour

Rated for 20,000 RPM maximum operating speed, the polyester YF-weight backing resists heat buildup during continuous grinding. Closed-coat coverage maintains consistent cutting action across the full disc surface.

Upgrade Context

These extra-coarse 36-grit discs replace worn or finer-grit abrasives when aggressive stock removal is required on metal or wood. The jump is worth it for heavy deburring, weld blending or rapid shaping tasks where finer grits would load or cut too slowly.

Questions about this item

How much heat does the 361F disc generate when running continuously at 20,000 RPM?

The disc is rated for heat resistance and its polyester backing helps dissipate heat during extended high-speed sanding.

What backing pad or holder is required to use the TS quick-change system?

A TS-type quick-change holder or backing pad that accepts the turn-on/turn-off mechanism is needed to mount these 3-inch discs.

Will the 36-grit aluminum oxide discs load quickly on older paint or body filler?

The closed-coat 36-grit aluminum oxide provides aggressive stock removal and resists loading on paint and filler surfaces.
