Fire Coating

This Titanium Aluminum Nitride (TiN-TiAlN) multilayer coating is applied to HSS and carbide drills. It offers outstanding wear resistance in drilling operations and high heat resistance. Besides conventional wet applications this coating is suitable for minimum lubrication and dry machining.

All-round coating achieving at least twice the performnace of TiN. Combines the advantages of TiN, TiAlN and TiCN. Excellent, near "fire resistant" heat resistance. High toughness. FIRE plus MolyGlide - the ideal combition for dry and HSC machinig.
