High-performance indexable CBN insert VBGW 1604..-2N RTC20T

The VBGW 1604..-2N RTC20T CBN insert is a well-conceived solution for demanding hard turning tasks. This particular model features two highly hard CBN cutting edges coated with a protective layer of titanium nitride (TiN). This effective combination promotes high wear resistance and convincing thermal stability when turning hardened steels. The insert truly shows its strengths in applications that require continuous to slightly interrupted cuts. This allows tight tolerances and excellent surface finishes to be achieved reliably, even when working on complex workpiece contours.

Applications

This CBN indexable insert is firmly geared towards professional use in hard machining operations. Typical fields of application include tool and mold making, general mechanical engineering, and the automotive industry, where hardened steel components require precise turning. The VBGW geometry is exceptionally well-suited for versatile longitudinal and contouring tasks. Whether performing continuous cuts or dealing with slight interruptions, the tool creates highly favorable conditions for consistently superior component quality.

Special features

A key feature of the RTC20T grade is the TiN coating specially tailored to the CBN cutting material, which significantly increases wear protection and promotes thermal endurance during hard turning. The provision of two precisely crafted cutting edges offers economic benefits and supports efficient machining workflows in daily operations. Furthermore, the precise shaping of the insert contributes to reduced vibrations and facilitates smooth cutting conditions on the workpiece.
