VBGW160404TM-2 WBH20 indexable turning insert — CBN grade, Rhombic 35° (Walter Tools)

The VBGW160404TM-2 WBH20 is a CBN-grade indexable turning insert designed for hard and wear-intensive turning tasks, offering a 35° rhombic geometry and a small corner radius for precise finishes

• CBN grade for hard materials
• Rhombic 35° insert geometry
• 0.4 mm corner radius for precision
• 5° clearance angle for stable cutting

Maximised throughput for hard machining

The CBN composition of this grade delivers exceptional wear resistance and lifetime stability when machining hardened steel and similar hard materials. Cubic boron nitride is a superabrasive optimised for high-temperature, high-pressure cutting, which translates into fewer index changes and longer productive tool life. Paired with the Rhombic 35° geometry, the insert enables stable engagement and consistent chip control, so cycle times are reduced and uptime increases. The result is a measurable improvement in process reliability and overall machining economy.

Consistent edge strength and surface quality

A 0.4 mm corner radius balances edge robustness with the ability to achieve tight dimensional control and a fine surface finish. The modest radius increases the strength of the cutting edge under heavy loads, lowering the risk of edge chipping during interrupted cuts. Together with the 5° clearance angle, the insert maintains a stable cutting line and predictable wear behaviour, simplifying tool-path programming and post-process inspection. This combination supports repeatable component quality, especially in series production of hardened parts.

Application guidance and material compatibility

Marked for hard turning, the grade WBH20 from the Walter CBN range is primarily intended for hardened steels and can be applied to pre-hardened materials as indicated. Depending on the workpiece alloy and process parameters, the grade may also be considered for demanding cast or superalloy tasks where wear is dominant. The insert is supplied in the VBGW160404TM-2 format suitable for holders accepting a Rhombic 35° insert form; confirm holder compatibility prior to use.

FAQ

Which materials is this insert mainly suitable for?
The VBGW160404TM-2 WBH20 insert is primarily suitable for hardened steels and pre-hardened materials, reflecting the CBN grade’s focus on wear-resistant, hard turning tasks.

What does the WBH20 designation mean for performance?
WBH20 is a Walter CBN grade engineered for stable cutting and high wear resistance; users of the VBGW160404TM-2 WBH20 can expect extended edge life in demanding hard-machining applications.

How does the 0.4 mm corner radius affect part quality?
A 0.4 mm corner radius provides a compromise between edge strength and precision, improving robustness during heavy cuts while enabling a high-quality surface finish on turned components.

Is the insert compatible with standard rhombic 35° holders?
The insert is supplied in a VBGW format with Rhombic 35° geometry; it fits holders designed for that insert form—verify holder compatibility before mounting.

Can this insert be used for interrupted cuts or roughing operations?
The CBN composition and the 0.4 mm corner radius give the insert good resistance to wear and edge damage, making it suitable for demanding interrupted or roughing operations on hardened materials, within the constraints of machine and process parameters.
