Run straight onto a right angle grinder, are a one-step system for grinding and blending. The 339 is a wheel with abrasive being resin mounted onto the spindle.

Fast cutting aluminium oxide abrasive

Flexible X-weight backing

Spindle mounted

Excellent cut and polish capabilities

These flap wheel brushes are used with power tools. Suitable for light deburring, cleaning, polishing and finishing when preparing metals, woodworking, stone smoothing, and paint or rust removal.

While both discs can be used for wood and metal surfaces, flap discs are better suited for use with metal. Abrasive discs are better at removing material from a surface, but for grinding metal surfaces, flap disc presents a more durable and long-lasting solution. They even have some advantages over grinding wheels in that, while they may not remove metal as aggressively, they are slightly safer to use and produce less sparks.

Flap discs should be stored flat, avoiding damp and frost or wide temperature variations.

P40 Grit – Useful when you need to remove heavy stock from a surface.

P60 Grit – For when you need to remove stock from a surface, but will need to refine the finish.

P80 Grit – This is for light stock removal and sharping only.
