DNGA150408TM-2 WBH10C indexable turning insert – CBN grade for hardened steels, rhombic 55° by Walter Tools

DNGA150408TM-2 WBH10C is an indexable turning insert designed for hard machining tasks, optimised for use on hardened steels and related high-wear materials

• CBN grade WBH10C for hard turning
• 0° negative rake for exceptional edge strength
• Rhombic 55° form for multi‑direction turning
• 0.8 mm corner radius for robust edge life

Enhanced productivity through CBN technology and wear resistance

The insert is built on a coated CBN cutting grade (WBH10C) that excels where conventional carbides reach their limits. CBN offers very high wear resistance, which reduces flank wear and maintains cutting geometry during long series runs. For operations on hardened steels and other highly abrasive materials, this results in consistent cycle times and less frequent index changes, supporting improved machine uptime and lower total processing costs. The combination of CBN and the Walter CBN series design enables a controlled wear pattern that helps preserve surface finish throughout tool life.

Geometry that prioritises edge security and process stability

The rhombic 55° geometry paired with a 0° (negative) rake delivers a particularly stable cutting edge for interrupted cuts and heavy cross-sections. A 0.8 mm corner radius increases edge strength and reduces the risk of chipping under high forces, while the plate size and thickness are chosen for high clamping stability. Negative rake geometry shifts cutting forces into the tool body rather than the cutting edge, which is advantageous when machining pre‑hardened or hard materials, leading to predictable tool behaviour and repeatable dimensional accuracy on workpieces.

Application focus and predictable results in hard turning

Designed for the ISO H material group, the insert is intended primarily for hard turning of hardened steels and similarly demanding alloys. The Walter CBN / hard-material series described for this insert emphasises broad material coverage within hard machining and reliable performance under high abrasive loads. In practical terms, the insert supports stable surface quality and repeatable tolerances in production environments where tool-life predictability and process safety are critical. The DNGA150408TM-2 WBH10C designation reflects the size and grade combination tailored for these exact tasks.

FAQ

What materials is this insert intended for?
The DNGA150408TM-2 WBH10C insert is intended for hardened steels (ISO H group) and similar hard, abrasive workpiece materials where CBN technology provides superior wear resistance.

How does the 0° negative rake influence cutting performance?
Negative rake at 0° increases edge strength and enhances process stability; the Walter Tools CBN insert sustains heavy cutting forces with reduced chipping risk compared with positive-rake geometries.

Which toolholders fit a DNGA150408TM-2 insert?
Toolholders designed for DNGA‑format turning inserts accept this insert form; the DNGA150408TM-2 WBH10C designation denotes the insert geometry and size for matching clamping systems.

Is this insert suitable for interrupted cuts or roughing operations?
Yes; the combination of rhombic 55° geometry, 0° rake and a 0.8 mm corner radius gives robust edge security suitable for interrupted cuts and heavy roughing in hard materials.

What performance benefits can be expected in production runs?
When used in appropriate hard-turning applications, the WBH10C CBN grade offers stable tool life, consistent surface finish and fewer index changes, which supports higher production reliability and lower downtime.
