Flap discs - from the manufacturer NovoAbrasive

What is a flap disc?

A flap disc (also known as a flap disc or flap disc) is an abrasive tool for grinding and polishing, consisting of overlapping flaps of abrasive paper secured to a plastic or fibre backing. Unlike Grinding discs, flap discs provide a softer and more controlled finish with better surface quality.

NovoAbrasive produces flap discs in three series — Standard (corundum), Profi (zirconium) and Extreme (ceramic grain). Each series is designed for a specific load level and budget.

How to choose grit size

Tip: Start with a coarser grit and gradually move to a finer one. For example: weld seam - P40, then P60, then P80 to prepare for painting.

Types of abrasive grain

Ceramic grain (EXTREME series)

The most productive type. The microstructure of the ceramic ensures continuous self-sharpening under load. The resource is 2–3 times greater than zircon. Ideal for industrial volumes and hard alloys.

Zircon (PROFI series)

Optimal price/life ratio. Self-sharpening under load, works without clogging. Recommended for daily professional work, stainless steel and hard metals.

Corundum (STANDARD series)

Aluminum oxide is a classic abrasive. Affordable price, sufficient resource for household and infrequent work. Well suited for carbon steel and general grinding.

T27 vs T29 — which shape to choose

Rule: If you work mainly at an angle (welds, corners) - T29. If you grind surfaces - T27.

Product series
