With these extremely stable inserts the highest cutting data is possible, very smooth running even with less powerful machines and thin walled components.

Dragonskin technology with 8 cutting edges for maximum economy

Exact 90° – no programming adjustment necessary

Precision ground insert for perfect axial and radial run-out accuracy

Maximum process reliability due to the extremely stable insert Maximum tool life due to the stable insert location positioning and Dragonskin coating

New Dragonskin Coating

Very high efficiency with 8 usable cutting edges

the first choice for machining non, low and high alloyed steels

The first choice for machining austenitic, ferritic and martensitic stainless steels

The first choice for the machining of ductile and malleable irons and sintered steels

Dragonskin – the correct Dragon for every material typeIn combination with the Dragonskin coating system 4910 is not only extremely hard-wearing, but also provides a maximum performance and process reliability.
