DNGA150608TM-2 WBH30 – indexable turning insert with CBN grade for hardened steels | Walter Tools

The DNGA150608TM-2 WBH30 is an indexable turning insert engineered for hard turning and finishing of hardened steels and similar high-hardness alloys.

• CBN grade WBH30 for hard turning
• Rhombic 55° geometry for stable cuts
• 0° negative rake for robust edge strength
• Corner radius 0.8 mm for consistent finishes
• Size 15 with thickness code 06

Maximised performance for hard machining

The combination of CBN technology and the WBH30 grade provides excellent wear resistance in demanding hard-turning operations. This wear-resistant bond is optimised for elevated temperatures and high contact pressures typical of machining hardened steels, which leads to extended tool life and more reproducible cycle times. The result is a measurable improvement in productivity and less frequent indexable insert changes, contributing to a more stable production flow.

Geometry designed for repeatable, secure cuts

The rhombic 55° form and 0° negative rake create a geometry that prioritises edge strength and stability over aggressive penetration, making it well suited to interrupted cuts and rough hard turning. The 0.8 mm corner radius supports consistent surface finish and reduces stress concentration at the cutting edge. The built-in chipbreaker 2 controls chip formation during stable cutting regimes, helping to maintain predictable chip flow and reduce secondary finishing work.

Built for hardened steels and pre‑hardened components

Belonging to the Walter CBN / Hard material series, this insert is specified for hardened steels and pre-hardened workpieces where conventional carbide grades would wear prematurely. The CBN-based composition is particularly effective on materials classified under the H group, delivering process security and repeatable surface quality when machining high-hardness steels, cast variants or alloyed superalloys depending on application parameters.

Standardised designation for easy integration and inventory

The ISO-style designation DNGA150608TM-2 and the WBH30 grade ensure straightforward toolholder compatibility and inventory management. Using the standardised insert designation simplifies procurement and replacement planning, and the robust negative-rake design reduces the risk of edge chipping during handling and indexing. This combination supports lowered process interruptions and a predictable maintenance cadence across production lines.

FAQ

What materials is this insert suitable for?
The DNGA150608TM-2 WBH30 is intended for hardened steels and pre-hardened components; the CBN composition is tailored to maintain edge life on H‑group materials.

How does the WBH30 grade benefit hard turning?
WBH30 is a CBN grade that offers high wear resistance and thermal stability, which reduces flank wear and preserves dimensional accuracy during prolonged hard machining.

Which geometry features contribute to edge strength?
The rhombic 55° shape combined with a 0° negative rake and a 0.8 mm corner radius increases edge robustness and improves performance in interrupted or heavy cutting conditions.

Is this insert compatible with standard DNGA toolholders?
Yes; the ISO designation DNGA150608TM-2 indicates compatibility with corresponding DNGA toolholders and enables straightforward replacement and inventory control.

What does chipbreaker 2 mean for machining results?
Chipbreaker 2 provides controlled chip formation for stable cutting when machining hardened steels, aiding consistent surface finish and reducing the risk of entanglement.
