3M 777F Quick Change Disc 2in P120G
The 3M 777F Quick Change Disc is a ceramic-coated abrasive designed for medium-grade sanding tasks. Its 2-inch diameter and TR quick-change system suit detail work on metal, composite and painted surfaces. The orange polyester backing resists heat during extended use. It fits right-angle die grinders and rotary tools that accept TR-style holders.
P120 Grit Determines Cut and Finish
The single specification that decides fit is the P120 grit grade, which sets the aggressiveness and surface profile. Medium grit removes material faster than fine grades but leaves a smoother finish than coarse ones. Verify the workpiece material and desired finish match this grit before purchasing.
TR Quick-Change Mount Installs in Seconds
The TR quick-change backing locks onto a compatible holder with a quarter-turn motion, requiring no tools. Ensure the tool spindle runs true and does not exceed the 25 000 RPM maximum operating speed. Common issues arise when the disc is seated off-centre or when the holder wears, causing vibration and premature edge wear.
