DNGA150604TM-2 WBH20C – indexable turning insert, CBN grade for hard machining (Walter Tools)

A DNGA150604TM-2 WBH20C indexable turning insert designed for demanding hard-turning applications, featuring a CBN cutting grade suited to hardened steels and a rhombic 55° geometry for versatile tool engagement

*CBN cutting grade for hardened steels
*Rhombic 55° insert geometry
*0.4 mm corner radius for robust edge
*0° negative rake for stable cutting

Exceptional wear resistance for hard turning performance

The combination of a CBN cutting material and the WBH20C grade delivers outstanding wear resistance when machining hardened steels. The use of cubic boron nitride as the primary cutting phase is specifically intended for conditions with high tool loads and abrasive contact; this results in prolonged tool life and predictable wear behaviour. For process planners, the result is improved uptime and fewer index changes, which supports leaner production cycles and consistent component tolerances.

Geometry and edge design that stabilise the cutting process

A rhombic 55° insert form together with a 0° negative rake creates a geometry that favours stable machining under heavy cut conditions. The relatively small 0.4 mm corner radius balances edge strength with achievable surface finish, while the chipbreaker 2 assists in controlled chip formation during interrupted or continuous cuts. These features translate into reduced vibration, more reliable chip control and a lower risk of edge chipping in hard turning operations.

Application benefits: predictable results and easier process specification

Designed for hard materials, this insert is suitable for applications involving pre-hardened and hardened steels, ensuring a consistent approach across a range of components. The tolerance class G and series designation reflect manufacturing precision that supports repeatable positioning and clamping strategies. For production engineers, specifying a CBN insert of this class reduces the need for excessive machining allowances and contributes to achieving target surface integrity without extensive trial cuts.

Procurement and integration into tooling systems

The insert is offered in the familiar indexable format of the DNGA family and can be integrated into existing toolholders that accept this ISO designation. The robust nature of the WBH20C grade and the clear material grouping for hardened steels simplify grade selection in machining documentation. For clients seeking optimised process windows, the combination of grade, geometry and chipbreaker allows straightforward parameter derivation based on cutting speed, feed and depth of cut typical for CBN machining.
