1-inch Quick-Change Sanding Discs

The 3M 11411 361F discs are 1-inch coated abrasives designed for detail sanding on die grinders or rotary tools. They suit metalworkers and technicians who need fast disc changes on small surfaces. The TR quick-change system locks each disc securely for high-speed use. This pack contains fifty pieces for extended workshop supply.

Coarse 50-grit Aluminium Oxide on YF-Weight

Grade 50 aluminium oxide cuts aggressively on steel, welds and heavy coatings while the closed coating resists loading. The YF-weight polyester backing adds tear resistance for edge work and contoured parts. Heat-resistant properties help maintain cutting life during sustained contact. Maximum rated speed is 30,000 RPM for high-RPM tools.

Replaces Slower Sheet Cutting or Larger Discs

These 1-inch discs upgrade from hand-cut sheets or larger discs that cannot reach tight radii, corners or interior profiles. The quick-change mandrel cuts setup time when switching between multiple grits on a single job. The jump is worth it when access is restricted and frequent disc changes are required. Not suited for wide-area stock removal or fine finishing stages.

Will the 1 in 361F disc fit the TR quick-change holder on my existing sander?

The disc uses the TR quick-change system and has a 1 in diameter, matching standard TR holders of that size.

How can I confirm the 361F discs are running at the correct speed after mounting them?

Run the sander up to its rated speed; the discs are rated for a maximum operating speed of 30 000 RPM.

Does the PK50 pack include a backup pad or only the 50 coated discs?
