Tetrabond™ DLC

Non-hydrogenated 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.

For complex tool geometries and a broad range of carbides

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.
