The ULTIMATECUT© Countersink. Technically perfect.
More powerful and Faster
- Up to 30 % time saving
- Up to 2 times more countersinks
- Optimal, smooth lowering result
The completely new cutting edge geometry and the RUnaTEC coating make the ULTIMATECUT countersink an all-rounder that achieves the best performance in almost all materials and applications.
Revolutionary chip space geometry and optimised variable relief grinding
Specially developed chip space parameters, such as the rake angle, transition radius and the extra wide flute, ensure optimum chip and heat removal and therefore enable very high wear resistance. The new geometry also counteracts material welding and greatly reduces countersinking forces. The specially developed, variable undercut ensures a very smooth countersinking process. This produces an optimum surface quality and therefore guarantees the best countersinking results. (With the new RUnaTEC coating, the quality of the surface can be improved even further).
The difference you can feel: refinement at the highest level
Our ULTIMATECUT premium line guarantees a doubling of tool life and even simpler and more effortless cutting of even the most demanding materials thanks to RUKO's own RUnaTEC coating, which is actually noticeable.
The RUnaTEC coating has extremely high wear resistance and nano-hardness, increased hot hardness, does not cause material welding and achieves optimum, smooth surfaces.

"The ULTIMATECUT© countersink achieves the best performance in almost all materials and applications. When developing the countersink, we specifically focussed on an equal pitch of the cutting edges. This advantage has also been confirmed by an independent test on the ULTIMATECUT© countersink and countersinks from competitors with unevenly spaced cutting edges, carried out by the Technical University of Darmstadt. The result is less wear and very smooth running, which in turn results in an optimised countersink surface."
