Versatile, full strength, high performance drilling

Whether stainless steel or cast iron, whether first use or recoated: with its unique nanostructure, BALINIT® PERTURA boosts productivity when cutting a variety of challenging materials and increases process reliability under difficult application conditions.

Profit from PERTURA, the successor to the BALINIT® FUTURA and HELICA coatings. Its nano-layer structure assures optimal balancing of residual stress, hardness and fracture toughness and thus consistently prevents crack propagation. This enables higher cutting speeds than with other coatings as well as extended tool lifetime, even when deep-hole drilling or using minimum quantity lubrication.

  • Very high abrasion resistance
  • Very high tool stability
  • Extra smooth surface
  • Perfect for minimum quantity lubrication
  • Excellent oxidation resistance
BALINIT PERTURA

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.
