DNGA150408TM-M2 WBH10 – Walter Tools CBN indexable turning insert, Rhombic 55°, 0° negative rake

DNGA150408TM-M2 WBH10 is a CBN-grade indexable turning insert for hard machining of hardened steels and similar difficult-to-machine materials

• CBN grade WBH10 for hard turning
• Rhombic 55° geometry for versatile turning
• 0° negative rake for stable cutting conditions

High wear resistance for hard, repeatable turning

The insert is produced with a CBN cutting grade (WBH10), designed specifically for the demands of hard machining. CBN (cubic boron nitride) provides significantly higher abrasion resistance than conventional carbide grades, which translates into longer tool life and fewer insert changes during serial production. This results in steadier process parameters and lower overall machining costs when working with hardened steel and pre-hardened components.

Stable cutting geometry that supports productivity

The rhombic 55° geometry and 0° negative rake deliver a reliable cutting stance that reduces vibration and supports consistent chip control under heavy cutting forces. The combination of the M2 chipbreaker with the chosen geometry enables controlled chip formation in interrupted cuts and finishes, improving surface quality without the need for frequent parameter adjustments. This configuration is particularly suitable where dimensional stability and repeatable surface integrity are required.

Practical benefits and machine-side considerations

Incorporating a DNGA-type insert with a 0.8 mm corner radius balances edge strength and profile accuracy: it resists edge wear while still allowing fine turning finishes. The insert is intended for use in suitable toolholders designed for DNGA-style parts and benefits from stable clamping and correct axial setup. Operators achieve higher uptime and fewer regrinds when the insert is paired with appropriate cutting data for CBN grades and the expected workpiece hardness.

FAQ

What materials is this insert suitable for?
The DNGA150408TM-M2 WBH10 insert from Walter Tools is intended primarily for hardened steels and pre-hardened components; the WBH10 CBN grade is engineered for hard machining tasks.

How does the M2 chipbreaker affect performance?
The M2 chipbreaker is designed to produce controlled chips during turning; when combined with the rhombic 55° shape it enhances chip control and surface finish for interrupted and continuous cuts.

Can this insert replace carbide types for hard turning?
For operations on high-hardness materials, the WBH10 CBN insert offers superior wear resistance and process stability compared with standard carbide inserts, often resulting in fewer tool changes and more consistent production.

Is a special toolholder required for DNGA inserts?
The insert requires a compatible DNGA-style toolholder with correct clamping for secure seating and stable cutting; correct axial set-up and holder rigidity are essential for best performance.

How does the 0.8 mm corner radius influence results?
A 0.8 mm corner radius increases edge strength and wear resistance while still allowing acceptable surface quality, making it a compromise between durability and finish.
