3M™ 769F Flap Disc – T27 | 4-½″ × 7/8″ | 60+ Grit | Precision-Shaped Ceramic Grain

Maximum cut without the premium price

Powered by 3M’s PSG triangles, 769F slices rather than ploughs, staying sharp, running cooler, and removing more metal per disc than conventional AO or zirconia alternatives. The result: faster beveling, smoother blends, and fewer disc changes—all while keeping abrasive spend in check.

• 60+ grit for rapid stock removal on carbon or stainless steel.

• Type 27 (flat-face) minimizes gouging on flat work pieces.

• Fiberglass backing + polyester flaps withstand high pressure without glazing.

• Rated 13 300 RPM—ideal for any 4-½″ right-angle grinder.

• Cuts, grinds, and blends in one step; often eliminates the need to switch discs.

Typical applications

• Heavy weld grinding and bevel prep

• Rust & mill-scale removal

• Edge deburring / chamfering

• Surface prep before coating or painting
