3M 361F Quick-Change Disc P100 1in

These 3M 361F quick-change sanding discs use aluminum oxide abrasive on a polyester backing with closed coating. The TR attachment system fits compatible rotary tools for fast disc swaps. Each pack contains fifty 1-inch discs graded P100 for medium material removal.

Capacity and headroom for P100 grit

The P100 grade handles general-purpose sanding, blending and surface preparation on metal, wood and composites. Aluminum oxide cuts consistently at speeds up to 30000 RPM. The closed coating loads faster on soft or resinous materials, so very aggressive stock removal or non-ferrous work may require a coarser grit or open-coat alternative.

Upgrade path from hand sanding or slower discs

Switching from manual sanding blocks or screw-on discs reduces changeover time and improves finish consistency on contoured parts. The quick-change TR system is worth it when workflow demands frequent grit changes or access to tight radii. Buyers who need larger diameters, different attachment types or higher heat resistance for extended heavy grinding should verify compatibility before purchasing.

Questions about this item

Will the 1 in TR quick-change disc fit the older 1 in TR holder I already own?

Yes, the disc uses the TR quick-change system so it locks onto any compatible 1 in TR holder you are already using.

How can I confirm the disc is running correctly after I mount it?

Spin the tool up to the rated 30, 000 RPM maximum; the disc should run true with no wobble and cut smoothly at P100 grit.

Does the PK50 pack contain only the 50 brown aluminum-oxide discs or are backup pads included?

The box holds 50 coated abrasive discs; backing pads or holders are not included and must be purchased separately.
