DNGA150612TM-2 WBH10C turning indexable insert — Walter Tools, CBN grade for hard turning

The DNGA150612TM-2 WBH10C is a rhombic 55° CBN-coated turning insert engineered for hard and pre-hardened steels, offering high wear resistance and stable cutting performance in demanding hard‑turning applications.

• CBN grade WBH10C for hard materials
• Rhombic 55° geometry for stable cutting
• Negative 0° rake for robust chip control
• 1.2 mm corner radius for high edge strength

Improved wear resistance for hard‑turning processes

The combination of the WBH10C CBN grade and the Walter CBN series delivers notably higher wear resistance when machining hardened steels. CBN is specifically designed for high‑hardness applications, which means the insert maintains cutting edge integrity under elevated contact stresses. This results in longer intervals between index changes and more predictable production cycles, supporting tighter tolerances and consistent surface quality. The result is an economically efficient choice for shops facing frequent hard‑turning tasks.

Geometry engineered for stability and chip control

The rhombic 55° shape and the negative 0° relief provide a robust cutting geometry that minimises vibration and supports steady cutting forces. The integrated chipbreaker 2 promotes controlled chip formation in hard materials, reducing the risk of built-up edge and improving process stability. Together with the 1.2 mm corner radius, the insert offers a balance of strength and form retention that benefits interrupted cuts and medium‑to‑heavy cutting conditions, ensuring reliable component finish and dimensional repeatability.

Process benefits and application scope

Designed for the Walter CBN / Hartstoff series, this insert is optimised for hardened and pre‑hardened steels (material group H). The stable edge behaviour and coated CBN compound translate into higher process security and consistent results on serial production runs. For manufacturers requiring secure hard machining of shafts, rings or hardened housings, the insert reduces downtime related to tool wear and rework, improving throughput without compromising surface integrity.

Integration, specification and shopfloor guidance

The insert’s designation and core dimensions align with standard clamping systems for DNGA‑style inserts, simplifying retrofit into existing toolholders. Key measurable features include the 15 mm size and a thickness code 06, supporting compatibility checks during tool selection. The tolerance class G and the Walter series designation signal a production‑grade component suitable for industrial turning cells where repeatability and predictable performance are priorities.

FAQ

Is this insert suitable for interrupted hard turning?
The DNGA150612TM-2 WBH10C from Walter Tools is designed for hard turning and, thanks to the robust CBN grade and 1.2 mm corner radius, is well suited to many interrupted cutting scenarios.

Which materials can be machined with this grade?
The WBH10C grade is targeted at hardened steels and pre‑hardened components; the insert’s properties prioritise wear resistance and stable edge life for high‑hardness groups.

How does the negative 0° rake affect cutting performance?
A 0° (negative) relief increases edge strength and resistance to chipping, improving process security during heavy or unstable cuts while maintaining consistent chip formation with the integrated chipbreaker.

Can this insert be used in standard DNGA toolholders?
The designation DNGA150612TM‑2 indicates compatibility with DNGA‑style toolholders; matching the insert geometry to the clamping system ensures correct seating and repeatable performance.
