Performance Coatings
Performance Coatings
The right coating can make the difference between simply cutting a material and machining it efficiently. NEXGEN PROMAX coatings are matched to the material, temperature and wear conditions your cutting tools face.
Which Coating Should I Choose?
Material is the starting point. The operation, hardness, tool geometry, heat and cutting strategy can further influence the final choice.
Steels & General Machining
A tough, wear-resistant coating for a broad range of ferrous applications and difficult-to-machine materials.
Hardened Steels & High-Temp Alloys
Extremely hard and wear resistant for hard machining, demanding alloys and high-temperature cutting environments.
Aluminum & Non-Ferrous
Advanced carbon-based coating technology for ultra-sharp cutting edges, low material adhesion and high-precision machining.
Three Coatings. Different Strengths.
A-PROMAX
Our versatile coating option. Designed to combine toughness, heat resistance and strong wear performance across a broad range of machining applications.
T-PROMAX
Our hardest PROMAX option for demanding applications. Built around high hardness, wear resistance, surface quality and hard-machining performance.
X-PROMAX
Our premium non-ferrous solution uses advanced carbon-based DLC technology to maintain sharp cutting edges, minimize sticking and support high-precision machining.
Advanced DLC Performance
X-PROMAX uses an advanced ta-C carbon coating technology developed for demanding non-ferrous applications where cutting-edge sharpness, smoothness, wear resistance and precision matter.
