High-Performance Hard Turning: Indexable CBN-Insert DNGA 1506..-2N RTC20T

The indexable CBN-insert DNGA 1506..-2N RTC20T is a professional cutting tool specifically developed to meet the strict demands of hard turning operations. Combining cubic boron nitride (CBN) with a protective TiN coating, the RTC20T grade offers outstanding resistance when machining hardened steels. Designed with two cutting edges, it is ideally tailored for full to slightly interrupted cuts, making it a reliable addition to demanding industrial manufacturing processes.

Applications

Thanks to its specific composition, the RTC20T grade is an excellent choice for precise hard turning tasks in mechanical engineering, toolmaking, and the automotive industry. The insert reliably handles demanding tasks involving hardened steel materials. Because the cutting edges are engineered for full to slightly interrupted cuts, even workpieces with cross holes or shallow grooves can be machined with process reliability.

Special features

A key advantage of this insert is the TiN-coated CBN substrate, which easily absorbs the high temperatures and mechanical stresses typically encountered during hard turning. The two effectively usable cutting edges ensure cost-efficient tool life and minimize tool changes. Furthermore, the proven DNGA insert shape offers high stability, supporting a smooth machining process and contributing to excellent surface finishes.
