WNGA080408TM-3 WBH10 – Indexable turning insert, CBN grade for hardened steels, Trigon 80° | Walter Tools

A WNGA080408TM-3 WBH10 indexable turning insert engineered for hard turning of hardened steels and other high‑wear applications.

• CBN grade WBH10 for hard materials
• Trigon 80° insert geometry
• 0.8 mm corner radius for stable cutting
• 0° (negative) rake for heavy cuts

High process reliability and long tool life for hard turning

The use of CBN cutting material in the WBH10 grade gives a significant advantage when machining hardened steels: the insert maintains a stable cutting edge under high temperatures and abrasive wear. The Trigon 80° geometry increases cutting-edge engagement and provides improved chip control during heavy cuts, while the 0° (negative) rake contributes to increased cutting-edge strength. These technical characteristics translate directly into predictable tool life and reduced downtime, supporting continuous, efficient production in hard‑turning operations.

Precise, repeatable results with low setup complexity

The trigon shape and the 0.8 mm corner radius deliver a reliable blend of strength and finish capability, enabling both robust roughing passes and controlled semi‑finishing without frequent insert changes. Because the insert is specifically designed for hard materials, process windows are narrower but more stable; this means consistent surface quality and dimensional repeatability across batches. Clamping is standard for Trigon inserts, so integration into existing turning toolholders is straightforward and setup time is minimised, benefiting throughput and shopfloor predictability.

Application guidance, benefits and material scope

WBH10 is optimised for hard machining tasks and suited primarily to hardened steels (material group H). Depending on the specific cutting conditions and workpiece alloys, CBN grades can also perform well on certain cast irons or superalloys, but WBH10 is focused on high‑wear, hard turning. The combination of CBN chemistry and the insert’s geometry reduces flank wear and preserves dimensional accuracy under heavy loads, making it a sound choice when process stability and repeatable component quality are required.

FAQ

Which materials is this insert intended for?
The WBH10 CBN grade is intended primarily for hardened steels (material group H); depending on conditions, CBN can also work on some cast irons or superalloys, but the WNGA080408TM-3 WBH10 is optimised for hard machining.

How does CBN WBH10 compare to conventional carbide inserts for hard turning?
CBN in the WBH10 grade provides superior wear resistance and thermal stability compared with carbide when machining hardened steels, resulting in longer tool life and improved process stability for the WNGA080408TM-3 WBH10.

What machining tasks suit the Trigon 80° geometry?
The Trigon 80° shape balances cutting‑edge strength and accessibility for turning profiles; it is well suited to roughing and semi‑finishing where a robust edge and effective chip control are required.

Is the insert suitable for finishing operations?
Yes — with appropriate feeds and speeds the 0.8 mm corner radius and the insert’s geometry can deliver controlled surface quality; however, finishing on high‑precision components may require optimised cutting parameters.

Does the negative 0° rake angle limit cutting speed?
The 0° (negative) rake prioritises edge strength for heavy cuts and interrupted machining; cutting speeds should be set according to workpiece hardness and machine capabilities to balance tool life and productivity when using the WNGA080408TM-3 WBH10.
