BALIQ ANTOS Running smoothly into stainless steels for longer tool life

Tapping is often the final manufacturing step, and ensuring a high-quality product in this critical final phase requires taps to work efficiently and reliably. Therefore, a high-performance coating plays an important role in the production process: it significantly improves wear resistance, enables a favourable torque curve and enhances chip formation and removal.

We have used all our experience and expertise to develop BALIQ® ANTOS which is based on the pioneering S3p technology enabling extremely hard coatings with very smooth surfaces and outstanding adhesion.

BALIQ® ANTOS consists of an AlCrN base coating with excellent wear resistance that offers high performance, especially when tapping stainless steel. The WC/C top coating provides exceptional friction and lubrication properties with high temperature resistance. This produces a smooth running-in effect, with optimized chip formation and removal as a result. The low torque with fewer peak loads helps ensure stable performance and longer tool service life.

General remark All given data are approximate values, they depend on application, environment and test condition.
*Coating hardness HIT [GPa] Measured by nano indentation according to ISO 14577. For multilayers the hardness of the different layers varies. Hardness can be adapted to the application.
***Intrinsic stress [GPa] Measured by XRD and/or bending method (Stoney equation). The calculated thermal stress has been substracted.
****Max. service temp. [°C] These are approximate values out of the field. Due to thermodynamic laws there is a dependency of pressure in application.
