Coarse Ceramic Flap Disc for Aggressive Grinding

The United Abrasives-Sait 77760 flap disc uses a coarse 40 grit ceramic abrasive for fast stock removal on metal surfaces. It is built for weld grinding, edge bevelling and heavy deburring tasks in fabrication shops. The GF series construction resists loading and maintains a consistent cut rate throughout the disc life. This disc fits standard angle grinders used in professional metalworking environments.

High-Speed Operation at 13,300 RPM

Rated for a maximum speed of 13,300 RPM, the disc delivers high material removal rates under normal grinding pressure. The ceramic grain structure runs cooler than conventional abrasives, reducing heat discolouration on the workpiece. Vibration is minimised by the balanced flap design, lowering operator fatigue during extended use. Always match the tool speed to the disc rating for safe operation.

Questions about this item

How do I mount the 77760 flap disc on my angle grinder without the arbor hole binding?

Match the disc bore to the grinder spindle, snug the flange nut by hand, then tighten with the supplied wrench while holding the spindle lock — overtightening distorts the backing plate and causes vibration at 13300 RPM

When should I replace the 40 grit ceramic flaps instead of continuing to grind?

Replace the disc once the flaps wear down to the backing plate or the ceramic grain stops cutting cleanly — a glazed surface generates heat and reduces material removal on steel or welds
