Quick-Change Sanding Discs

These 3-inch coated abrasive discs use a TR quick-change system for fast swaps on compatible sanders. The pack contains fifty P100-grit discs built with aluminum-oxide grain on a heat-resistant polyester backing. They are rated for a maximum operating speed of 20,000 RPM.

Medium stock removal and surface prep

Suited for metalworkers and technicians who need consistent medium-grade finishing on contours or flat areas. Not intended for heavy grinding, aggressive material removal, or applications that demand finer finishing grits.

TR quick-change attachment

The TR fastening system locks each disc securely to the backing pad and releases it with a quarter turn. Compatibility depends on the sander accepting TR-type quick-change discs.

Questions about this item

What quick-change system does the 3M 22405 disc use, and what maximum operating speed does that interface support?

The disc uses a TR quick-change system and is rated for a maximum operating speed of 20,000 RPM.

What backing diameter and weight must the backup pad match for the 3M 22405 disc to mount securely?

The disc has a 3 in overall diameter and a YF-weight polyester backing, so the backup pad must match that size and weight rating.

How do you install the 3M 22405 disc on a TR holder, and what step is often missed?

Align the disc with the holder, press firmly, then twist to lock; the step often missed is fully seating the disc before twisting so the TR lugs engage completely.
