CNGA120408TM-MW2 WBH10C turning insert — CBN grade, rhombic 80°

The CNGA120408TM-MW2 WBH10C is a rhombic 80° indexable turning insert designed for productivity in hard‑turning applications and the machining of hardened steels.

• CBN grade WBH10C for hard materials
• Rhombic 80° geometry for versatile tool set‑up
• 0° negative rake for stable cutting forces
• 0.8 mm corner radius for robust edge life
• MW2 chipbreaker for controlled chip formation

Performance tuned for hardened steels and demanding cuts

The CBN‑based WBH10C grade delivers exceptionally high wear resistance where conventional carbide grades reach their limits. Its composition is optimised for the machining of hardened steels, enabling longer tool life and fewer insert changes. With a negative rake of 0° the insert reduces cutting‑edge deflection and improves stable cutting under high contact loads, which in turn supports predictable cycle times and less scrap in serial production.

Consistent edge strength and chip control for quieter processes

A 0.8 mm corner radius provides a balance between edge strength and achievable surface finish, offering robustness on interrupted cuts while maintaining acceptable surface quality. The dedicated MW2 chipbreaker shapes swarf into controllable segments, lowering the risk of entanglement and simplifying chip evacuation. Together these features reduce secondary handling and contribute to a safer, more efficient machining environment.

Practical benefits for process reliability and set‑up flexibility

The rhombic 80° form allows multiple approach angles and easy indexability, which reduces set‑up complexity and minimises downtime for tool changes. Classified for hard materials, this insert supports the shift to more productive hard‑turning strategies, improving throughput without compromising repeatability. Selection of this grade from Walter Tools can lead to measurable process improvements where wear resistance and edge stability are critical.

FAQ

What materials is this insert designed for?
The CNGA120408TM-MW2 WBH10C insert is specified for hardened steels and favourable for pre‑hardened and other high‑hardness steel applications thanks to its WBH10C CBN grade.

How does the MW2 chipbreaker affect machining?
The MW2 chipbreaker ensures consistent chip segmentation and evacuation, reducing swarf issues and improving process safety when using this Walter Tools indexable turning insert.

Is the 0° negative rake suitable for heavy cuts?
Yes, the 0° negative rake increases edge stability under high cutting forces, making the insert appropriate for heavier engagement typical in hard‑turning operations.

Can this insert be rotated for multiple cutting edges?
The rhombic 80° geometry permits indexing to fresh edges, supporting longer tool life and flexible toolholder positioning without compromising cutting performance.
