3M 777F Quick-Change Disc, 2 in, 36 Grit

This 3M 777F quick-change sanding disc measures 2 inches in diameter and uses a ceramic abrasive on a YF-weight polyester backing. The TR attachment system locks the disc onto a compatible holder for fast swaps. Rated for up to 25,000 RPM, the extra-coarse 36-grit surface removes material aggressively. Heat-resistant properties help maintain cutting performance during extended use.

Metal-fabrication shops and heavy stock removal

The extra-coarse grit and ceramic grain suit weld grinding, scale removal and rapid shaping on steel or stainless. Closed-coat coverage keeps the surface loading resistant under high pressure. Buyers who need fine finishing, wood sanding or a flexible backing for contours should look at something else. The TR quick-change hub will not fit hook-and-loop or threaded spindle tools.

Fits TR quick-change holders on right-angle die

The disc mounts directly to a TR-style holder, so the operator needs a matching quick-change backup pad and a pneumatic or electric die grinder rated for at least 25,000 RPM. No adhesives or additional hardware are required. The 2-inch diameter reaches tight corners and small welds that larger discs cannot access. Heat resistance reduces glazing during continuous high-speed operation.

Questions about this item

What type of backup pad and holder are required for the TR quick-change system?

A compatible TR-style backup pad with a 2-inch diameter and a maximum speed rating of at least 25,000 RPM is required to mount this disc securely.

Can this 36-grit ceramic disc be used on the same backup pad as finer-grit 777F discs?

Yes, any 2-inch 777F disc using the TR quick-change system fits the same backup pad, allowing quick grit changes without removing the pad.

How can I confirm the disc is seated correctly before running the tool at 25,000 RPM?

The TR fastener should snap firmly into the backup pad with a distinct click; the orange ceramic face must sit flat and centred with no visible wobble when spun by hand.
