DNGA150608TM-2 WBH10 indexable turning insert — CBN grade for hard machining, Walter Tools

The DNGA150608TM-2 WBH10 is a CBN indexable turning insert engineered for hard turning of hardened steels and other high-wear materials, offering a stable cutting edge and reliable performance in demanding finishing and semi-finishing operations.

• CBN grade WBH10 for extreme wear resistance
• Rhombic 55° geometry for versatile turning
• 0° negative rake angle for robust cutting
• Corner radius 0.8 mm for consistent edge strength

Maximise productivity in hard turning with CBN performance

The combination of a CBN cutting material and a rhombic 55° geometry delivers a decisive advantage when machining hardened workpieces. Because cubic boron nitride is significantly harder and more thermally stable than conventional carbides, the insert maintains cutting-edge integrity at elevated temperatures and high contact pressures. This translates into reduced flank wear, longer tool life and fewer tool changes, which in turn supports a higher machine uptime and predictable cycle times. The specification DNGA150608TM-2 WBH10 references an insert designed specifically for these conditions and is optimised for the machining of hardened steels as defined by ISO material group H.

Process stability and consistent surface quality for finishing

A 0° negative rake combined with a 0.8 mm corner radius focuses on robustness: the negative rake increases edge strength and reduces the risk of chipping when cutting hard materials, while the radius promotes a stable contact zone that helps produce consistent surface finishes. For applications where repeatability and component integrity are paramount, such as bearing bores or hardened shafts, this geometry reduces vibration sensitivity and supports tighter process windows. The insert’s tolerance class G further underlines suitability for precision turning where dimensional consistency across index changes is required.

Practical application guidance and machining scope

The WBH10 grade is intended for hard machining tasks and demonstrates best results in finishing and semi-finishing of hardened steels and similarly abrasive alloys. The insert’s chipbreaker 2 and its form factor (rhombic, 55°) allow flexible use across a range of turning operations including facing and light profiling. While the grade excels on hard materials, selection of cutting parameters should account for machine rigidity, workpiece clamping and coolant strategy: conservative cutting depths and stable feeds will maximise the insert’s service life under challenging conditions. For process planning, the insert thickness and seat compatibility must be verified against the chosen toolholder.

Reliable choice for industrial production environments

Specified as part of the Walter CBN / hard material series, this insert supports high-volume and repeatable production where tool life and process security are critical. The combination of a robust geometry, purpose-designed CBN grade and a clear designation simplifies inventory management and tool selection for batch production. Operators benefit from fewer interventions and more consistent outputs, while production planners gain a tool solution that is tailored to the unique demands of hard turning.

FAQ

What materials is this insert designed for?
The DNGA150608TM-2 WBH10 insert is designed primarily for hardened steels and other high-wear materials; its CBN composition targets hard turning applications.

How does the WBH10 grade improve process stability?
WBH10’s CBN composition provides exceptional wear resistance and thermal stability, which results in more consistent edge life and improved process stability during extended runs.

Is the negative rake angle suitable for roughing?
The 0° negative rake angle favours robustness and edge strength, making the insert well suited to demanding cuts and interrupted cutting, though it is optimised for finishing and semi-finishing of hard materials.

What does the rhombic 55° shape allow in terms of applications?
The rhombic 55° geometry offers flexible approach angles for facing and light profiling, enabling use across a range of turning tasks while maintaining good access to shoulders and narrow features.

How does the corner radius affect surface quality?
The 0.8 mm corner radius helps create a stable contact area, reducing edge loading and promoting consistent surface finishes when machining hardened components.
