BALINIT HELICA BALINIT HELICA, an AlCrN-based coating, has made it possible to systematically optimise and decisively improve the key coating properties for drilling applications.

BALINIT HELICA Greater abrasion resistance, extra shear strength, lower adhesion tendency, maximum toughness and a very smooth surface achieve a quantum leap in drilling performance.
