TNGA160408TS-3 WBK20 indexable turning insert — Walter Tools, CBN grade, triangle 60°

The TNGA160408TS-3 WBK20 is a triangle 60° indexable turning insert designed for demanding, wear‑intensive turning tasks where CBN performance and edge security are required

• CBN grade WBK20 for hardened materials
• Triangle 60° insert for versatile turning
• 0.8 mm corner radius for robust edge

High-performance cutting for hardened components

The use of CBN (WBK20) as the cutting material provides markedly improved wear resistance and edge stability compared with conventional grades when machining hardened steels and comparable substrates. This results in longer tool life and fewer index changes, which supports higher machine utilisation and consistent part quality. For production environments where repeatability and low downtime matter, the CBN composition reduces the frequency of regrinding or replacement and helps maintain process windows for tight tolerances.

Geometry and edge design that deliver secure results

The triangle 60° plate form combined with a 0.8 mm corner radius and a 0° (negative) rake creates a sturdy cutting edge that tolerates interrupted cuts and heavy contact loads. The broader cutting edge area also helps to distribute forces, lowering the risk of chipping in roughing passes. The integrated chipbreaker 3 supports controlled chip formation and evacuation, which is particularly beneficial during continuous production runs where stable chip flow reduces the likelihood of rework and tool-related stops.

Practical application guidance and material suitability

This insert is optimised for applications that demand high abrasion resistance; suitability for gusseisen, superalloys or other materials must be verified against the product matrix. The designation and series information indicate that the grade is intended for hard and highly abrasive conditions: check the specific workpiece material and machining parameters before series deployment. For customers seeking reliable setup values or parameter examples, Metav Werkzeuge’s technical team can advise on feeds, speeds and coolant strategies to achieve the desired surface finish and component integrity.

FAQ

What materials is this insert best suited for?
The TNGA160408TS-3 WBK20 is manufactured in a CBN grade (WBK20) and is best suited for hardened steels and other abrasive, hard materials; compatibility with specific alloys should be checked against the product matrix.

How does the 0° negative rake affect machining?
A 0° (negative) rake provides a stronger cutting edge and increased resistance to chipping under heavy loads, which is why the TNGA160408TS-3 WBK20 is recommended for robust turning operations.

Is the chip control suitable for continuous production?
Yes, the integrated chipbreaker 3 supports controlled chip formation and evacuation, improving process stability during continuous runs with the TNGA160408TS-3 WBK20.

What benefits does the 0.8 mm corner radius bring?
The 0.8 mm corner radius increases edge strength and distributes cutting forces more evenly, reducing the risk of chipping and enabling more aggressive roughing passes.

Where can machining parameters for this insert be obtained?
Typical feeds and speeds for the TNGA160408TS-3 WBK20 can be provided by Metav Werkzeuge’s technical advisors, who will match parameters to the workpiece material and machine capability.
