Roughing grinding discs with cloth flaps coating with Zirconium Aluminium Oxide (ZA) or ceramic grit on backing pads of steel, plastic or glass fibre. Circumferential speed ideally 50-60 m/s, max. 80 m/s. Gentle, cool grinding with high self-sharpening effect (no clogging); low vibration and low force working, low noise level.

• Flat shape − for surface grinding − and weld dressing with approach angles 0 -15°.

Flap disc with glass fibre pad and mixed fabric with high metal removal rate and long service life.

Universal for all steels, preferably for use on flat surfaces.
