Oerlikon Balzers’ BALINIT® PERTURA – and it keeps on drilling, just thrilling!

BALINIT® PERTURA is a coating developed by Oerlikon Balzers especially for high-performance carbide drills. Regardless of whether for machining operations in steel or cast iron, for new or recoating: With its unique nanolayer structure, BALINIT® PERTURA enhances the stability and process reliability of your tools even under difficult machining conditions. In the machining laboratory we tested three carbide drills of the same type in three different variants: - uncoated - Standard TiAlN coating - BALINIT PERTURA The machining parameters: - Carbide drill Ø 8.5mm - Cutting speed 80m/min - Drilling depth 15mm (blind hole) The workpiece: DIN 1.7225 (42CrMo4) 1000MPa Dry The results: - Uncoated 28 holes: end of tool life - Standard TiAlN 2208 holes: end of tool life - BALINIT® PERTURA 4540 holes: keeps on drilling It is just 3 µm, but they make the big difference: carbide drills coated with BALINIT® PERTURA drilled more than twice as many holes. This means reduced tool changing and increased machine service life. Moreover, machining times are shortened, which in turn allows for maximum machine capacity utilisation as well as savings in production costs. The features and advantages of BALINIT® PERTURA at a glance: Nanolayer structure and specific layer composition: Consistent prevention of crack growth and versatile application in high-end drilling Optimal balance between residual stress, hardness and fracture toughness: Applications at moderate and high cutting speeds possible Enormous abrasion-resistance and high hot hardness: Considerably extended tool lifetimes Extremely smooth coating surface: Trouble-free chip transport and reduction of cutting forces Outstanding oxidation resistance: Very high tool stability, especially of the cutting edges and extremely high service life, even with deephole and dry drilling More about BALINIT® PERTURA: https://www.oerlikon.com/balzers/com/en/portfolio/balzers-surface-solutions/pvd-and-pacvd-based-coatings/balinit/tialn-based/balinit-pertura/
