DNGA150604TM-2 WBH20 indexable turning insert — CBN for hardened steels, Walter Tools

The DNGA150604TM-2 WBH20 is an indexable turning insert engineered for heavy-duty hard turning and finishing of hardened steels, providing wear-resistant cutting performance in demanding production environments.

• CBN grade WBH20 for hard turning
• Negative 0° geometry for stable cutting
• Rhombic 55° form with 0.4 corner radius
• Optimised chipbreaker for consistent chips

Longer tool life and dependable hard‑turning performance

The CBN-based WBH20 grade delivers markedly increased resistance to abrasive wear, which translates into longer tool life and fewer tool changes in series production. With its negative 0° geometry, the insert sustains high cutting forces and improves seat stability in rigid toolholders, reducing the risk of edge chipping during interrupted cuts. The combination of a stable grade and robust geometry helps maintain dimensional accuracy and surface quality through extended runs, supporting predictable machining cycles and improved overall equipment effectiveness.

Predictable surfaces and controlled chip formation on hardened materials

Designed specifically for machining hardened steels and pre‑hardened components, the insert’s optimised chipbreaker and Rhombic 55° form promote consistent chip flow and reliable heat distribution at the cutting edge. These characteristics minimise secondary operations by improving surface integrity and reducing spool-up of heat that can alter tolerances. The insert is therefore suitable where repeatable finishes and tight tolerances are required, such as in the manufacture of shafts, bearing seats or hardened components subject to high loading.

Integration into productive machining processes

With a compact size 15 profile and thickness 06, plus a 0.4 corner radius, the insert balances cutting strength with the ability to achieve fine surface finishes where needed. The standardised ISO designation ensures compatibility with a broad range of toolholders specified for DNGA-style inserts, facilitating quick changeovers and process standardisation. The result is a cost‑efficient solution that supports higher productivity, fewer regrinds and consistent batch quality in components produced from hard and pre‑hardened steels.

FAQ

What materials is this insert intended for?
The DNGA150604TM-2 WBH20 insert is intended primarily for hardened steels and is also suitable for machining pre‑hardened steel grades in demanding turning operations.

How does the WBH20 grade benefit production runs?
WBH20’s CBN composition provides high wear resistance and a stable cutting edge, which reduces downtime for tool changes and supports consistent part quality across long production runs.

Which geometry features assist with chip control?
The Rhombic 55° form combined with the optimised chipbreaker (type 2) promotes controlled chip formation and evacuation, helping to preserve surface finish and reduce the risk of built‑up edge.

Is this insert compatible with standard DNGA toolholders?
Yes, the DNGA150604TM-2 WBH20 follows the DNGA-style ISO designation and is compatible with toolholders designed for DNGA inserts, enabling straightforward integration into existing tool systems.

What operational advantages does the negative 0° geometry provide?
The negative 0° geometry increases seat stability and resistance to edge breakage under high radial loads, making it well suited to interrupted cuts and heavy finishing passes with consistent dimensional results.
