DNGA150608TS-2 WBK20 — CBN turning insert, Rhombus 55°, 0° negative (Walter Tools)

The DNGA150608TS-2 WBK20 is an indexable turning insert engineered for demanding hard-turning tasks and for applications on highly abrasive or hardened materials.

CBN grade for hard materials Rhombus 55° geometry for versatility 0° negative for robust cutting stability

Consistent wear resistance for hard turning and abrasive alloys

The combination of CBN cutting material and the WBK20 grade provides a reliable solution for operations where tool life and reproducibility matter. CBN is specifically designed for highly abrasive and hardened workpieces, which translates into reduced tool change frequency and more predictable cycle times on series parts. This stability supports a leaner process flow and can lower overall machining costs when compared with conventional grades, because fewer interruptions and consistent surface quality reduce rework and inspection time.

Geometry engineered to improve process stability and chip control

The Rhombus 55° shape together with a 0° negative rake and a 0.8 mm corner radius create a geometry that promotes secure clamping and stable cutting forces. The defined chipbreaker 2 encourages predictable chip formation, which is particularly beneficial in automated or lights-out turning where reliable evacuation is essential. These geometric features help maintain cutting edge integrity under higher contact stresses, giving more reproducible part tolerances and better control over surface finish in tough machining scenarios.

Practical application guidance and integration into the production line

Selection of the correct grade and cutting data should be matched to the workpiece material matrix; the WBK20 grade is intended primarily for hardened steels and may also be applicable to certain cast irons or superalloys depending on the specific product matrix. The insert designation and series details facilitate straightforward toolholder matching and inventory management, while the defined tolerance class G aids in predictable clamping. For shops seeking to standardise inserts across multiple operations, this indexable option balances long tool life with integration ease, supporting efficient shop-floor routines and reliable part quality.

FAQ

What materials is this insert intended for? The DNGA150608TS-2 WBK20 is designed primarily for hardened steels and other highly abrasive materials; suitability for cast iron or superalloys depends on the specific application matrix and should be verified before use.

How does the Rhombus 55° geometry affect cutting performance? The Rhombus 55° geometry offers versatile approach angles, improved clearance in turning profiles and stable engagement, which helps the insert maintain consistent contact conditions and repeatable results on serial parts.

What advantages does CBN WBK20 provide over conventional grades? CBN in the WBK20 grade delivers superior wear resistance and edge stability during hard turning, reducing tool changes and contributing to steadier cycle times and surface finishes over long runs.

Is the 0° negative rake suitable for heavy interrupted cuts? Yes, the 0° negative rake contributes to robust edge strength and secure clamping, making the insert well suited to operations where cutting forces are high or interruptions occur.

How should chip control be handled with this insert? The chipbreaker 2 geometry supports controlled chip formation; pairing the insert with appropriate cutting data and coolant strategy will enhance evacuation and reduce the risk of chip entanglement.
