2 in 80 Grit Ceramic Quick-Change Disc
This 3M 60650017233 disc is a coated abrasive made for aggressive stock removal on metal surfaces. The ceramic grain and 80 grit coarse grade suit fabrication shops and maintenance crews who need fast cutting action on a compact tool. The TR quick-change system locks the disc in seconds for minimal downtime. The orange 777F series backing resists heat buildup during extended grinding sessions.
TR Quick-Change Mounting and 25,000 RPM Rating
The TR attachment fits directly onto compatible right-angle die grinders and rotary sanders with a matching quick-change holder. A 2 in diameter disc reaches tight corners, weld seams and contoured panels that larger pads cannot access. The 25,000 RPM maximum operating speed matches high-speed pneumatic tools without requiring adapter bushings. The polyester YF weight backing provides a stable platform that resists tearing under lateral pressure.
Sustained Cutting With Heat-Resistant Ceramic Grain
Ceramic abrasive fractures continuously to expose fresh cutting edges, maintaining a consistent cut rate throughout the disc life. The closed-coat coverage distributes load evenly across the surface to reduce glazing when pressure is held constant. Heat resistance in the grain and bonding system prevents premature dulling during long passes on hard alloys. The disc is not designed for fine finishing or polishing tasks that demand a finer grit or softer backing.

Questions about this item
What maximum RPM should I observe so the 2 in ceramic disc does not over-speed under sustained use?
The disc is rated for a maximum operating speed of 25,000 RPM; running the tool above that limit risks disc failure and excess heat.
How much heat builds up when the 777F series disc runs all day on a right-angle sander?
The ceramic grain and polyester YF backing are designed with heat resistance, so extended sanding sessions stay cooler than conventional aluminium-oxide discs.
Which quick-change backup pad do I already need for the TR attachment system to work?
A 2 in TR-type quick-change backup pad is required; the disc’s plastic button locks directly onto that pad without tools.
