TC burrs - FVK/FVKS cut

Tungsten carbide burrs with the FVK and FVKS cuts are suitable for universal use on hard glass and carbon-fibre-reinforced duroplastics. Due to its high concentricity, the FVK cut is suitable for tool machines and manual applications. It is characterized by smooth milling and produces a smooth cut edge.
The FVKS cut is suitable for use on machines and robots with high feed rates.


  • Particularly suitable for GRP and CRP, also with > 40 % fibre content.
  • The FVKS cut produces smooth edges and is characterized by smooth milling.
  • Reduced wear on the tool drive due to impact-free work without chatter marks, thanks to the high concentricity.

Materials that can be worked:

  • Plastics
  • Fibre-reinforced plastics (GRP/CRP) with a fibre content > 40 %


  • Trimming
  • Contour milling
  • Deburring
  • Milling grooves and pockets (with FSTS)
  • Drilling blind holes (with FSTS)
  • Drilling with minimal burr formation (with STS)
  • Milling out
  • Cutting out holes

Matching tool drives:

  • Flexible shaft drive
  • Straight grinder
  • Robot
  • Machine tools

Recommendations for use:

  • The version with a drill cut (BS) is particularly suitable for machine and robot applications, while the version with a centre drill (ZBS) is used for manual applications. It allows secure drilling on almost all surface conditions.
  • Select a burr diameter greater than the thickness of the material to be machined, to avoid impacts and chattering with the risk of damaging or breaking the tool.
  • Increase the rotational speed if the tool tends to chatter.
  • If necessary, reduce the rotational speed and contact pressure if melting occurs.
  • If possible, use the tools on powerful drives with elastically mounted spindles to avoid vibration.
  • For the cost-effective use of burrs, work with higher rotational/cutting speeds.
  • Power recommendation for tool drives:
    • Shank diameter of 3 mm: 75 to 300 watts
    • Shank diameter of 6 mm: from 300 watts
  • Please observe the rotational speed recommendations.
