Indexable CBN-Insert DCGW ...-2N RTC20T
The indexable CBN-insert DCGW ...-2N RTC20T is a professional cutting tool tailored for hard turning operations on hardened steels. Combining the extreme hardness of Cubic Boron Nitride (CBN) with a wear-reducing TiN coating, this two-edged insert opens up high-performance possibilities. It supports stable processes where hard materials need to be machined reliably, whether in continuous turning or with slight interruptions.

Applications
The DCGW ...-2N RTC20T is focused on hard turning within mechanical engineering, as well as tool and mold making. It is particularly effective for machining hardened steel components where precise contours and excellent surface finishes are required. Its preferred application range covers smooth turning cuts up to operations involving slightly interrupted cuts.
Special features
The CBN cutting material, combined with the proven TiN coating, ensures high temperature resistance, allowing the insert to withstand the thermal and mechanical stresses of hard turning. The design featuring two cutting edges ensures economical tool utilization in professional workshop environments.
