Flap discs in industrial quality

First-class stock removal. Excellent tool life. Comfortable and safe working.

Our flap discs are optimised for surface and weld seam processing and enable:

  • High cutting performance ensures fast working progress without heat discolouration
  • Comfortable working with low vibration
  • Long tool life, for example through self-sharpening ceramic grain
  • Optimum grinding results on freely shaped parts such as pipes, housings and attachments – even if materials are difficult to machine
  • Numerous grain sizes and diameters offer you the suitable tool at all times – for every use

Possible processing tasks for flap discs:

  • Surface grinding
  • Chamfering
  • Deburring
  • Weld seam processing

Materials that can be processed:

  • Steel
  • Stainless steel (INOX)
  • Titanium
  • Nickel and alloys such as aluminium

Our flap discs are suitable for use on all angle grinders and cordless angle grinders.

KÖLN HITEC – zirconia

This flap disc is characterised by a particularly high flap density and conveys a cushioning feeling, especially suited for finishing. A high material ratio ensures extremely long tool life.

  • Up to 60% more material than our tried-and-trusted zircon flap discs

Details:

Suitable for: Angle Grinder

For especially aggressive material removal we recommend regular zircon or ceramic flap discs.

KÖLN MINI-POWERFLEX – ceramic and zirconia

Mini flap discs are perfect for grinding small surfaces or hard-to-reach areas – even with changing contours.

Compared to conventional grinding discs, these tools feature more flexible grinding behaviour, a more uniform grinding pattern and a longer tool life. The tool life advantage is even more significant compared to single layer discs.
Ideal for weld seam or precision processing, for the removal of excess cast in the cleaning room, as well as chamfering and deburring.

  • Universal application options
  • Uniformly high stock removal and excellent service life
  • Cost reduction thanks to reduced changing times
  • Tool-free and quick mounting on the corresponding backing pad or shank adapter

KÖLN MINI-POWERFLEX – ceramic

Self-sharpening ceramic grain ensures consistently high stock removal and excellent service life. In particular on hard and tough materials, such as super alloys or stainless steel (INOX).

The quick change system with plastic outer thread (R-type) makes straightforward and safe tool change possible in no time.

Details:

Suitable for: Straight Grinder
Suitable for: Mini Angle Grinder

Aluminium backing: Enables high contact pressure.
