TNGA160404TM-3 WBH10C indexable turning insert — CBN grade for hard turning (Walter Tools)

The TNGA160404TM-3 WBH10C is a triangular 60° indexable turning insert in a coated CBN grade, engineered for hard turning of hardened steels and pre-hardened components.

• CBN grade WBH10C for hard turning
• Triangular 60° insert for robust seating
• 0.4 mm corner radius for stable edge life
• 0° negative rake for controlled cutting forces

High-performance wear resistance for hard materials

The coated CBN grade WBH10C provides exceptional wear resistance in operations on hardened steels (ISO group H). As a superabrasive, cubic boron nitride maintains cutting-edge geometry under high thermal and mechanical stress, which reduces flank wear and helps keep tolerances stable over longer tool life. For production environments that demand repeatable batch-to-batch accuracy, this behaviour translates into fewer tool changes and more predictable cycle times.

Stable geometry that supports precise turning

The triangular 60° form, combined with a 0.4 mm corner radius and a 0° negative rake, gives mechanical strength at the cutting edge and consistent contact conditions in the cut. The three-sided format allows for multiple indexed cutting edges per insert, while the modest corner radius balances edge robustness with the potential for good surface finish. The specified chipbreaker 3 promotes controlled chip formation in hard materials, which reduces risk of built-up edge and contributes to steady machining performance.

Optimised for process reliability and productivity

Designed within the Walter CBN / Hartstoff series, this insert supports machining strategies where tool life and process security are primary criteria. The combination of a coated CBN substrate and a restrained geometric setup reduces unplanned downtime caused by premature edge failure. For shops producing hardened shafts, bearings or other high-hardness components, the result is a measurable improvement in throughput and fewer interruptions for tool replacement, supporting leaner production flows.

Application guidance and practical notes

The insert is intended for hard turning of hardened steels and is suitable for pre-hardened workpieces as indicated by the specification. The designation reflects a compact form (size 16) with a robust thickness and a precision corner; matching insert seat and clamping torque are essential to ensure the intended stability. Adjustments to feed and depth of cut should be made within the process window for hard materials, and coolant strategy should follow machine and workpiece requirements. For materials outside the specified groups, tool choice should be reviewed against the workpiece characteristics.

FAQ

Which materials is this insert designed for?
This insert is designed primarily for hardened steels and pre-hardened steel applications; the WBH10C CBN grade targets ISO group H for hard turning tasks.

What does the designation TNGA160404TM-3 indicate?
The designation identifies the insert geometry and size: triangular 60° form with the series and size coding TNGA160404TM-3 and the CBN grade WBH10C indicating its suitability for hard machining.

How does CBN compare with carbide for hard turning?
CBN provides superior thermal and abrasive wear resistance compared with conventional carbide, making it the preferred option for consistent edge life and dimensional stability when machining high-hardness materials.

Is this insert suitable for finishing and semi-finishing?
The combination of a 0.4 mm corner radius and a controlled geometry allows the insert to be used for finishing to semi-finishing in hard-turning sequences; achievable surface finish depends on process parameters and machine rigidity.

How many cutting edges can be used per insert?
The triangular form offers multiple indexable edges per insert; specifics depend on the mounted orientation and the clamping system in the chosen toolholder.
