WNGA080408TM-3 WBH30 indexable turning insert, CBN grade, Trigon 80° — Walter Tools

The WNGA080408TM-3 WBH30 is an indexable Trigon 80° CBN insert engineered for hard turning and reliable machining of hardened steels.

• CBN grade WBH30 for hard materials
• Trigon 80° geometry for secure clamping
• 0.8 mm corner radius for edge stability
• 0° negative clearance for robust cutting

Exceptional wear resistance for hardened workpieces

The insert uses the WBH30 CBN grade, a solution optimised for high-temperature and high-wear conditions typical of hard turning. CBN (cubic boron nitride) offers substantially higher abrasion resistance than conventional carbide grades, which translates into longer tool life and fewer index changes during production. For operations on hardened steels, this behaviour reduces downtime and stabilises component tolerances, improving process economics through extended insert life and more predictable replacement intervals.

Geometry and edge design that stabilises cutting

The Trigon 80° profile combined with a 0° negative clearance gives the insert excellent mechanical support in the pocket and reduces the tendency to deflect under heavy radial loads. The 0.8 mm corner radius enhances edge strength and evens out wear, promoting a consistent surface finish across batches. Together these features enable secure clamping, reliable chip formation and resistance to chipping when machining high-hardness workpieces, thereby increasing first-pass yield and maintaining dimensional consistency.

Process benefits and practical application guidance

This indexable insert is particularly suited to finishing and semi-finishing passes on hardened steels and pre-hardened components. The CBN grade minimises built-up edge and thermal wear, permitting stable cutting at higher feed rates where traditional grades would rapidly deteriorate. When integrating this insert into a turning process, consider rigid tooling, appropriate coolant strategies and verified clamping to exploit the grade’s benefits fully.

FAQ

What materials is this insert intended for?
The WNGA080408TM-3 WBH30 insert is specified for hardened steels and pre-hardened components, exploiting the high abrasion resistance of the WBH30 CBN grade.

How does the Trigon 80° geometry affect machining?
Trigon 80° provides strong support in the holder and, when combined with the 0° negative clearance, reduces deflection and promotes stable cutting with consistent surface quality on hard materials.

What benefits does the WBH30 CBN grade deliver compared with carbide?
WBH30 CBN offers superior wear resistance at elevated temperatures and under abrasive conditions, which leads to longer tool life, fewer index changes and more consistent process outcomes than conventional carbide grades in hard turning.

Are there specific setup recommendations for best performance?
For best results with this Walter Tools CBN insert, use rigid tooling, secure clamping and a process suited to hard turning; Metav Werkzeuge can advise on cutting data and process parameters tailored to the application.
