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.
