Q 1. What is the trim material in a Grittyflex cup brush?

A. Abrasive nylon filament impregnated with abrasive grit — Osborn calls this material Grittyflex.

Q 2. What grit and colour is this variant?

A. Grit 80, colour code red. According to Osborn, grit 80 (red) produces a coarser, more aggressive material removal.

Q 3. What shank does this brush have?

A. A 6mm shank for direct fitting into standard power drill chucks.

Q 4. What is the brush diameter and max RPM?

A. Diameter 75mm, maximum operating speed 4,500 RPM.

Q 5. Why choose an abrasive filament brush over a wire brush?

A. Osborn describes abrasive nylon trim as gentle on material compared to wire, and notes that it adapts to workpiece contours — making it suitable for curved and irregular surfaces where wire brushes might cause damage.

Q 6. Does the abrasive performance reduce as the brush wears?

A. No. Osborn states that as the filament wears, new abrasive grit is continuously released, maintaining a uniform removal rate throughout the tool life.

Q 7. What materials is this brush suitable for?

A. Osborn states it is suitable for all materials.

Q 8. Is this brush TÜV-Süd certified?

A. Yes — TÜV-Süd certified (safety tested, production monitored).

Q 9. Is a blue Grittyflex the same as a red Grittyflex?

A. No. Blue is grit 180 (finer), red is grit 80 (coarser). The colour coding makes them easy to distinguish.
