DNGA150608TM-2 WBH20C — indexable turning insert for hard machining (Walter Tools)

The DNGA150608TM-2 WBH20C is an indexable turning insert engineered for hard turning of hardened steels and similar high‑wear materials, offering stable cutting performance in demanding production environments.

• CBN grade WBH20C for extreme wear resistance
• Rhombic 55° geometry with 0.8 mm corner radius
• Negative 0° rake for stable hard turning

Extend machining intervals with CBN wear resistance

The coated CBN grade WBH20C delivers pronounced abrasion resistance and micro‑edge stability when machining hardened steels, which reduces the frequency of insert changes and unplanned downtime. Because cubic boron nitride retains cutting edge hardness at elevated temperatures, the result is a longer effective tool life and more consistent component tolerances. This makes the insert well suited for series production where process repeatability and low tool consumption are priorities.

Improve process security through stable cutting geometry

The negative 0° rake and the rhombic seating impart high cutting edge robustness and damp vibration during interrupted cuts. The combination of a rhombic 55° shape and a 0.8 mm corner radius creates a favourable balance between edge strength and surface finish, allowing secure feeds and depths of cut in hard turning operations. Tolerance class G supports repeatable seating and accurate indexation, which contributes to predictable cycle times and lower scrap rates.

Achieve reliable surface quality with an optimised edge design

The geometry and edge preparation of this insert are tuned for finishing and semi‑finishing passes on hard materials, producing consistent surface integrity with fewer rework steps. The presence of CBN as the cutting material favours thermal stability at the cutting zone, so workpieces are less prone to hardening‑related distortions. As a result, dimensional stability and surface quality are improved in series components where tight specifications are required.

Application suitability and production benefits

Designed for hard machining tasks, the insert is part of the Walter CBN / Hartstoff series and targets hardened steels and comparable challenging alloys. The robust design and wear‑resistant grade support higher productivity through longer tool life and better edge retention, yielding lower overall machining costs. Coupled with stable clamping and correct toolholder selection, the insert contributes to consistent batch quality and efficient tool management in the production workflow.
