TNGA160408TM-3 WBH30 Turning Insert — CBN grade WBH30, Triangle 60°, 0° negative rake by Walter Tools

The TNGA160408TM-3 WBH30 is a triangular indexable turning insert designed for hard machining and finishing of hardened steels, featuring a CBN WBH30 grade for prolonged tool life.

• CBN grade WBH30 for hard machining
• Triangle 60° geometry for consistent indexability
• 0° negative rake for stable cutting forces
• 0.8 mm nose radius for fine surface finish

Superior wear resistance for hard and abrasive materials

The CBN-based WBH30 grade delivers high wear resistance and stable cutting-edge performance when machining hardened steels. Cubic boron nitride (CBN) is a superabrasive that maintains a sharp edge at elevated temperatures and under high mechanical stress; this characteristic reduces flank wear and prolongs effective cutting life compared with conventional carbide grades. For operations that demand repeatable dimensions and lower downtime, the insert’s material choice translates into fewer tool changes and more consistent batch quality. The triangular indexable format also allows rapid rotation to fresh cutting edges, supporting continuous production.

Consistent chip control and surface quality through geometry

The triangular 60° shape combined with a 0.8 mm corner radius and an integrated chipbreaker 3 produces a controlled chip form and reduces vibration in interrupted or finishing cuts. The 0° negative rake stabilises cutting forces, which is particularly beneficial when confronting variable workpiece hardness or small overhangs; stable forces mean improved dimensional stability and more predictable tool life. Operators seeking improved surface finish will find the modest nose radius and chip control helpful for achieving tighter tolerances without resorting to lower metal removal rates.

Process benefits: predictable tool life and simplified logistics

Using a CBN insert from the Walter Tools CBN / hard material series supports higher process reliability in hard turning applications. The grade’s focus on hard machining reduces scrap risk and can lower overall machining costs by extending effective tool life. Indexable inserts like this one simplify tool inventory management because one insert supports multiple indexed edges; the triangular format offers three usable cutting corners per insert. For production planning, this means fewer tool set-ups and quicker interventions when replacements are required, contributing to improved machine utilisation and workflow efficiency.

FAQ

What materials is this insert intended for?
The WBH30 CBN grade is intended primarily for hardened steels and similar hard materials; the TNGA160408TM-3 insert is optimised for hard machining tasks.

How does CBN performance compare with carbide for hard turning?
CBN, as used in the WBH30 grade, maintains edge stability at higher temperatures and under heavy wear conditions, offering longer effective life than conventional carbide when machining hardened steels.

What effect does the 0.8 mm nose radius have on surface finish?
A 0.8 mm corner radius balances strength and finish: it supports a smooth surface in finishing passes while retaining edge robustness for interrupted cuts.

Is the triangular geometry beneficial for indexability?
Yes; the triangle 60° geometry provides three usable cutting edges per insert, enabling economical indexing and fast edge changes for continuous production.

What cutting conditions are typical for this type of insert?
Cutting conditions depend on workpiece hardness and machine rigidity; the WBH30 CBN grade is chosen when stable, wear-resistant performance is needed under hard-turning regimes.
