DNGA150612TM-M2 WBH10 CBN indexable turning insert for hardened steel — Walter Tools

The DNGA150612TM-M2 WBH10 is an indexable CBN turning insert designed for hard machining of hardened steels and similar wear‑resistant materials, offering a combination of abrasion resistance and reliable performance in repetitive production.

• CBN grade WBH10 for hard machining
• Stable cut with 1.2 mm corner radius
• Rhombic 55° geometry for versatile turning
• Negative 0° rake for robust cutting action

Longer productivity through wear‑resistant cutting grade

The application of a CBN cutting material reduces flank wear and extends tool life when machining hardened steels, making it a cost‑effective choice for serial production of heat‑treated components. The WBH10 grade is engineered for high abrasive resistance and dimensional stability, which lowers the frequency of index changes and helps maintain consistent part quality. By choosing a dedicated CBN insert, process windows become more stable and workpiece tolerances are easier to hold during long runs.

Geometry and edge design for secure machining

A Rhombus 55° shape paired with a corner radius of 1.2 mm provides a compromise between strength at the cutting edge and the ability to achieve acceptable surface finish in finishing and semi‑finishing passes. The negative 0° rake contributes to a robust cutting edge that resists chipping under heavy interrupted cuts and high radial loads. The indexable insert format permits quick reorientation and replacement, reducing machine downtime and keeping cycle times low while preserving operator safety and process repeatability.

Practical suitability and machining focus

This insert is specified for machining hardened steels and is appropriate where high hardness and abrasive wear dictate use of CBN technology. The M2 chipbreaker supports controlled chip formation in hard turning operations, improving evacuation and reducing the risk of built‑up edge. Tolerance class G and the standard 15 mm size family allow straightforward integration into common toolholder systems that accept DNGA‑format inserts, enabling fast adoption within existing turning setups and reliable production performance.

FAQ

What materials is this insert suited to machine?
The insert is optimised for hardened steels; the WBH10 CBN grade is selected specifically to handle the abrasive conditions encountered when hard turning.

How does the negative 0° rake affect machining performance?
A 0° negative rake produces a sturdier cutting edge, improving resistance to edge breakouts and favouring stable performance under higher cutting forces in hard material removal.

What does the DNGA designation indicate?
DNGA denotes the insert shape and clamping orientation; this indexable insert format suits toolholders designed for DNGA geometry and supports rapid index changes.

Why choose a 1.2 mm corner radius for hard turning?
A 1.2 mm corner radius balances edge strength and surface finish, offering improved edge life while still enabling attainable surface quality in finishing operations.

Is the M2 chipbreaker appropriate for interrupted cuts?
The M2 chipbreaker provides controlled chip formation in hard turning and contributes to reliable evacuation, which can help in conditions with mild interruption; heavy interruptions should be evaluated case‑by‑case.
