COUNTERSINKS

WORLDS FIRST

Revolution in countersinking
Finally smooth, fast and precise
Every machining process has latent potentials
for boosting productivity. Signicant potentials for improvement can be found even in
seemingly secondary machining operations –
as illustrated by the new generation of countersinks.
The newly developed countersink operates
with signicantly reduced axial forces. The
cutting edges of the new countersinks have
an uneven pitch. With this spacing, the axial
forces are reduced by more than 50% and the
radial forces by 25% compared with conventional countersinks. Such optimised operating
conditions create far less vibrations within the

tool, allowing higher accuracies and better
surface nishes to be achieved. The precision
of the countersink leads to an immediately
improved contact of bolted and riveted joints,
eliminating settling of the joint under load
after assembly. The reduced load on the machine also increases the tool life of the tools.
Thanks to the smooth and stable running, the
tools can also be operated with higher cutting
data, resulting in considerable savings in time.
The new countersinks (patent pending) raise
countersinking operations to a new technological level.
