Quick Change Disc 2 in 36 Grit

The 3M 361F series disc uses an aluminum oxide coating on a YF-weight polyester backing for aggressive stock removal. A TR quick-change hub locks the 2-inch pad onto compatible holders in seconds. Pack of fifty keeps high-volume sanding stations supplied. Brown colour coding identifies the extra-coarse grade at a glance.

Sustained Load Behaviour

Closed-coat coverage resists loading when material builds up during long passes on metal or wood. Heat-resistant bond holds grain at the rated 25,000 RPM without premature breakdown. Polyester backing resists stretching so the disc stays flat under continuous pressure. Consistent cut rate is maintained across the full pack.

Upgrade Context

Replaces conventional hook-and-loop discs where frequent grit changes slow workflow. The TR system cuts changeover time for operators running multiple grades in sequence. Not suited for finish sanding or fine surface preparation where a finer grit is required. Buyers needing larger diameters or different quick-change interfaces should verify holder compatibility.

Questions about this item

Will the 36-grit disc overheat when run at 25 000 RPM all day?

The disc is rated for heat resistance and a maximum speed of 25 000 RPM, so it is built to handle continuous high-speed sanding.

Does the TR quick-change system need a specific holder I might not have?

The disc uses a TR (Type R) quick-change attachment, so it requires a compatible TR backing pad or holder to mount on your sander.

Can I use these 2-inch discs on my older die grinder with a different arbor?

No, the TR quick-change interface only fits TR-compatible backing pads; it will not mount directly on a threaded arbor or other quick-change systems.
