TCGW110204TS-3 WBK20 turning insert (CBN) by Walter Tools — 7° clearance, 0.4 mm radius

The TCGW110204TS-3 WBK20 is a triangular 60° CBN turning and boring insert designed for high-wear, hardened materials in demanding metal‑cutting applications.

• CBN cutting grade WBK20
• 7° clearance angle for stable cutting
• 0.4 mm corner radius for fine finishes
• Triangle 60° plate for versatile turning

High-performance grade for demanding, hardened materials

The CBN‑based WBK20 grade provides excellent wear resistance and thermal stability for machining hardened steels and other highly abrasive materials. As a CBN solution, this insert is optimised to withstand the high contact temperatures and abrasive conditions of hard turning, meaning fewer tool changes and more predictable tool life. The combination of CBN chemistry and precision manufacturing reduces flank wear and preserves cutting edge geometry, which in turn supports consistent dimensional accuracy and lowers the risk of unplanned downtime in serial production.

Geometry engineered for surface quality and process stability

The triangular 60° plate form with a 0.4 mm corner radius and 7° clearance balances strength and finish. The modest corner radius improves surface integrity while limiting cutting forces, and the positive clearance reduces rubbing at the flank face, resulting in stable chip formation and reliable cutting conditions. The integrated chipbreaker 3 aids controlled chip evacuation under interrupted or heavy cuts. For operations where finish and repeatability matter, this geometry translates into fewer rework steps and a reproducible workpiece appearance.

Practical application and process integration guidance

This insert suits turning and boring tasks where high process reliability is required, especially on hardened components or materials that accelerate tool wear. Machine set-up should consider appropriate cutting data for CBN tooling and coolant strategy where applicable; consult the product matrix to confirm material compatibility and recommended speeds. The insert’s stable edge and wear characteristics contribute to predictable maintenance cycles and improved overall equipment effectiveness. For customers seeking higher throughput with reproducible quality, this grade and geometry combination supports productive, long‑run manufacturing.

FAQ

What materials is the WBK20 grade best suited for?
The WBK20 CBN grade is intended for hard and highly abrasive materials such as hardened steels; the insert is optimised for applications where wear resistance and thermal stability are critical.

How does the 7° clearance angle affect performance?
A 7° clearance reduces flank contact and rubbing, improving process stability and helping to maintain edge integrity for longer tool life under continuous turning conditions.

Can the triangular 60° design be used for light finishing cuts?
Yes, the triangle 60° form combined with a 0.4 mm corner radius offers a compromise between strength and fine surface finish, making the insert suitable for both finishing and general turning tasks.

Is this insert compatible with interrupted cutting or grooving operations?
The insert’s robust CBN grade and the chipbreaker design support interrupted cuts better than conventional grades; however, application-specific testing is recommended to verify performance under severe interruption.

What information should be provided when requesting technical support?
Provide the SKU (TCGW110204TS-3-WBK20-WALTER), workpiece material and hardness, machine type, and typical cutting parameters to allow Metav Werkzeuge to give tailored recommendations.
