DNGA150604TM-2 WBH30 turning insert – CBN grade for hardened steels (Walter Tools)

The DNGA150604TM-2 WBH30 is a rhombic 55° turning insert featuring a CBN grade optimised for hard-turning of hardened steels and high-wear workpieces

• CBN grade WBH30 for hard-turning
• Rhombic 55° geometry for versatile turning
• 0° negative rake for stable cutting
• 0.4 mm corner radius for consistent finishes

High productivity through wear-resistant CBN technology

The WBH30 grade is a CBN-based cutting material designed specifically for the demands of hardened steels and other high-wear applications. Using cubic boron nitride as the cutting phase delivers markedly improved tool life and wear resistance compared with conventional carbide grades when machining high-hardness materials. This insert’s metallurgy and grade selection reduce flank wear and the risk of premature edge degradation, so production runs remain consistent and downtime is minimised. For operations where repeatability and uptime matter most, the use of a CBN insert yields a tangible improvement in process economy.

Stable cutting geometry for consistent surface quality

The rhombic 55° geometry paired with a 0° negative rake gives this insert a robust cutting edge that resists chipping under heavy or interrupted cuts. The moderate 0.4 mm corner radius contributes to a balanced trade-off between strength and surface finish, producing reliable part quality without sacrificing edge stability. Together, these geometric choices support controlled cutting forces and improved chip control, which is particularly important when turning hardened components where vibration and edge damage are common concerns. The result is a consistent surface finish and fewer rework cycles.

Application range and machining guidance

Designed for the hard-turning sector, the insert is explicitly suitable for hardened steels (H) as defined in ISO material groupings. The combination of WBH30 grade and the insert’s geometry makes it ideal for finishing and semi-finishing in components subject to high contact stresses. Operators benefit from predictable wear behaviour and less frequent insert changes, which supports higher overall throughput. When selecting cutting parameters, it is advisable to rely on holder rigidity and appropriate coolant strategy for optimal performance with CBN inserts.

Compatibility and operational advantages

The insert is issued in the ISO designation DNGA150604TM-2 WBH30 and integrates with standard toolholders compatible with DNGA-style turning inserts. Its design focuses on process security and repeatable results, making it a pragmatic choice for shops aiming to consolidate grades for hard materials. The robust nature of the grade reduces the need for constant monitoring, enabling the machining centre to run with improved stability and fewer interruptions for tooling change.

FAQ

Which materials is this insert intended for?
The insert is designed primarily for hardened steels (ISO group H); the WBH30 CBN grade is optimised for hard-turning tasks and high-wear conditions.

What does WBH30 mean in practical terms?
WBH30 denotes Walter Tools’ CBN grade engineered for stable wear behaviour when machining hardened materials, offering extended tool life and consistent cutting performance.

How does the rhombic 55° geometry affect machining?
Rhombic 55° geometry provides versatile approach angles for external turning and supports a robust cutting edge that improves process stability and surface quality.

Why choose a 0° negative rake for this insert?
A 0° negative rake increases edge strength and reduces the risk of chipping during interrupted cuts, which is valuable when turning hardened components.

What role does the 0.4 mm corner radius play in results?
The 0.4 mm corner radius balances edge strength and finish quality, helping to maintain a smooth surface while resisting premature edge wear.
