rubber and thermoplastics. Thanks to the high
robots with high feed rates, as its smooth mill-

applications. The end cut allows both drilling

Cut FVK
Cut FVKS
Tungsten carbide burrs with both FVK and
FVKS cuts are suitable for trimming and
contour milling of a wide range of glass and
carbon-fibre reinforced plastics (GRP/CRP).
