VBGW160402TM-2 WBH20 indexable insert — CBN grade for hard turning (Walter Tools)

The VBGW160402TM-2 WBH20 is an indexable insert engineered for heavy-duty hard turning of hardened steels and other high-wear materials, combining a CBN cutting grade with a geometry optimised for stable cutting and repeatable results.

• CBN grade WBH20 for hardened steels
• Rhombic 35° form for versatile turning
• 5° clearance for reduced rubbing
• 0.2 mm corner radius for stable edge

Consistent performance for hard finishing and long tool life

The CBN-based WBH20 grade delivers very high wear resistance, designed specifically for machining hardened steels where conventional carbide grades wear quickly. The CBN substrate keeps the cutting edge stable at elevated temperatures and under heavy contact pressures, which translates into longer tool life and fewer insert changes. This stability benefits batch operations and rework-prone components by reducing variability and maintaining surface integrity during extended cycles.

Geometry that improves process security and surface quality

The Rhombic 35° shape combined with a 5° clearance and a 0.2 mm corner radius provides a balanced cutting geometry: radial strength for interrupted cuts, a cutting angle suited to axial and facing operations, and an edge form that supports controlled micro‑chipping rather than catastrophic failure. The insert dimensions (16 mm inscribed size, 4.0 mm thickness) make it suitable for a broad range of toolholders and turning conditions, while the integrated chipbreaker promotes predictable chip formation, lowering the risk of built-up edge and improving finished-surface consistency.

Application focus and process advice for reliable integration

This insert is intended for hard turning and finishing of pre‑hardened and hardened steels, delivering stable performance in demanding production environments. Adoption of CBN inserts typically allows higher cutting speeds or increased metal removal rates compared with wear-limited alternatives; however, emphasis should be placed on secure clamping, correct coolant and parameter selection to exploit the grade’s advantages. For tailored cutting data, batch optimisation or verification in a specific machine setup, Metav Werkzeuge provides application support and cutting-parameter guidance to ensure efficient integration into existing processes.

FAQ

What materials is this insert suitable for?
The VBGW160402TM-2 WBH20 insert is specified for hardened steels and pre‑hardened steel applications and performs reliably in hard-turning scenarios.

How does the CBN grade affect tool life?
The CBN cutting material in the WBH20 grade offers superior wear resistance under high temperature and pressure, extending tool life and reducing insert changes compared with conventional carbide grades.

Which geometry advantages does the Rhombic 35° provide?
The Rhombic 35° form offers versatility for axial and radial turning, improved accessibility in tight contours and balanced strength that supports interrupted and continuous cuts.

Is this insert compatible with standard indexable turning toolholders?
The insert’s 16 mm inscribed size and common Rhombic form make it compatible with many standard toolholders designed for this format; matching the seat and clamping style remains essential.

Does the insert require special cooling or clamping measures?
While the WBH20 grade tolerates higher temperatures, secure clamping and appropriate coolant strategies are recommended to maximise edge life and maintain process stability.
