Cutting Tools
Tetrabond™
DLC coating for complex tool geometries and a broad range of carbides
Non-hydrogenated Tetrabond™ DLC Coating. Tetrabond™ DLC is highly suited for machining abrasive materials such as graphite and high silicon content (>12%) aluminium alloys, composite materials and PEEK. The thin, extremely hard coating is designed to maintain maximum cutting edge sharpness. Tetrabond™ can be applied to complex tool geometries, brazed tooling and can be deposited on carbides and HSS materials. Its very low coefficient of friction exhibits excellent performance in machining a wide range of sticky materials.
