BALINIT PERTURA
The one solution for all
drilling applications
®
BALINIT® PERTURA
The reliable coating even for difficult applications
Effective immediately, the question
as to the right tool coating is irrelevant. Because now, you can opt for
BALINIT® PERTURA – the coating
for all high-performance carbide
drills. Whether steel or cast iron,
whether for first-time or recoating:
With its unique nanostructure,
BALINIT® PERTURA boosts productivity in cutting various challenging materials and simultaneously
increases process reliability under
difficult application conditions.
Every deployment pays off
BALINIT® PERTURA is the ideal coating solution for different drill geometries such as deep-hole, micro, or step
drills. Superb results are achieved even
in tough conditions, for instance with
materials like C70, GGG60 or GJV,
when drilling through holes, for non90° attack angles, or when working
with high-tensile-strength materials.
But BALINIT® PERTURA also gives you
that extra twist under minimum quantity lubrication conditions. Cooling can
be internal or external – all options are
possible.
For the utmost in performance
and flexibility
BALINIT® PERTURA is the impressive
outcome of the refined design, composition, and surface properties of our
BALINIT® FUTURA and BALINIT®
HELICA coatings.
- The specific coating composition
delivers extremely long service lives
even in deep-hole and dry drilling
applications.
- The nanolayer structure assures an
optimised balance between residual
stress and hardness.
- Optimized for both moderate and
high cutting speeds.
Our nanolayer concept – your
success recipe
BALINIT® PERTURA features an optimised layer configuration that gives
you numerous advantages:
- Prevention of crack propagation.
- Effective protection against wear due
to enormous abrasion resistance and
high hot hardness.
- Very smooth surface, ideal for deephole drilling and machining of demanding cast iron applications.
Chip evacuation is smooth
Drills coated with BALINIT® PERTURA
assure friction-free chip removal. This
is due to the extremely smooth surface
of BALINIT® PERTURA. Moreover,
it noticeably reduces cutting forces,
easing the stresses imposed on tools
and machines. The result: very high
machine availability and process reliability.
Benefit from the highest degree
of productivity
The excellent oxidation resistance and
hot hardness of BALINIT® PERTURA
are responsible for superb tool stability, especially at the cutting edges.
This prolongs tool-change intervals
and increases the service life of your
machine. Furthermore, shorter machining times maximise your capacity utilisation, which in turn reduces manufacturing costs.
Our nanolayer concept is exceptionally hard to beat
Now, BALINIT® PERTURA prevents crack propagation into the substrate even more systematically.

Reconditioning saves money –
again and again
BALINIT® PERTURA also means: Equal
to new – even after reconditioning.
When you use BALINIT® PERTURA
for consecutive recoating cycles, you
benefit from the same high level of performance and flexibility of a newly coated drill – with considerable savings up
to 50% after 3 reconditioning cycles.

Thanks to BALINIT® PERTURA, you
have two recoating options:
1. In decoating – the perfect solution
for precision tools – the worn coating
is gently removed from the substrate,
after which the new coating is applied.
2. Overcoating – the less expensive
alternative – consists in regrinding
the worn tool only at the functional
surfaces, after which the entire drill is
coated again.
