BALIQ ALCRONOS coated taps and reamers
Reamers are required to produce high quality products and high quality surfaces
Outstanding surface quality and precision for thread formers and taps
Outstanding surface quality and precision for thread formers and taps
Revolutionary thread forming and tapping mastery

Highly precise tools are required to produce components with high quality surfaces. The accuracy provided by new tools however declines with use. With the micron-precise BALIQ®ALCRONOS, precision tools such as thread formers, taps, reamers and stamping punches retain as-new precision, and process reliability is boosted.

Tool change frequency is noticeably reduced, even with hard-to-machine materials such as titanium and stainless steel, or when stamping challenging material such as Corson alloys. The revolutionary smooth coating ensures superb surfaces and, thus, top production quality. The AlCrN-based coating is, moreover, markedly less prone to built-up edge formation.

  • Reliable machining and forming
  • Reduced tool costs
  • Precision, high-performance coating
  • New manufacturing options
  • Superior manufacturing quality
  • Reliable mechanical finishing
  • High surface quality
BALIQ ALCRONOS
Coating material AlCrN-based
Coating technology S3p
Coating colour bright grey
Coating hardness HIT [GPa]* 37 +/-3
Intrinsic stress [GPa]*** -3.5 +/-1
Max. service temp. [°C]**** 1100
Process temperature [°C] < 500
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.
