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).
The end cut (BS) or the center drill (ZBS) allow
both drilling and milling work to be carried
out.
Recommended rotational speed range
To determine the recommended cutting speed
[m/min], please proceed as follows:
� Select the material group
that is to be machined.
� Determine the type of application.
FVK
New in the PFERD Product Line 202
Suitable for trimming and contour milling of
fibre-reinforced plastics GRP and CRP, hard
rubber and thermoplastics. Thanks to the high
level of concentric accuracy it is suitable for
use on stationary machines and hand-held
applications.
Advantages
� The special cutting geometry allows high
feed rates due to the low resistance.
� These special tungsten carbide burrs can be
plunged into solid material, allowing drilling
and milling work to be carried out in one
working cycle.
� The version with the end cut (BS) is particularly
suitable for use on machines and
robots.
� The version with the center drill (ZBS) is
particularly suitable for use with hand-held
tools.

TC Burrs for GRP/CRP
Similar to the FVK cut. Due to its special tooth
design it is suitable for use on machines and
robots with high feed rates, as its smooth milling
behaviour creates a burr free edge.
Application examples
� Trimming.
� Contour milling.
� Production of cut-outs.
� Deburring.
Recommendations for use
When processing thermoplastics, the speed
should be set to avoid the material melting
and clogging the burr.
� Select the required burr diameter.
� The cutting speed range and the burr
diameter determine the recommended
rotational speed range [RPM].
