3M™ 769F Flap Disc 10 Pack – T27 | 4-½″ × 7/8″ | 40+ Grit | Precision-Shaped Ceramic Grain

Cut faster, finish smoother—spend less

3M™ 769F brings the power of PSG to an everyday-priced flap disc. The triangular ceramic grains continually fracture into sharp points, slicing through carbon or stainless steel instead of ploughing—so you remove metal quicker while running cooler and with less operator pressure.

• One-step grind & blend – often eliminates the need to switch to a fibre disc or flap wheel.

• 40+ grit, coarse stock removal – bevels welds, cleans scale and heavy rust.

• Type 27 (flat-face) – ideal on flat surfaces; minimizes gouging on edges.

• Polyester flaps on a fiberglass backing plate withstand high pressure without glazing.

• Rated 13 300 RPM (4-½″ grinders) for safe, chatter-free grinding.

Typical applications

• Beveling and weld grinding on mild or stainless steel

• Edge deburring and chamfering

• Surface prep before painting or coating

• Rust and mill-scale removal
