VBGW160408TM-2 WBH20 Turning insert, CBN grade, Rhombus 35° — Walter Tools

The VBGW160408TM-2 WBH20 is a rhombic 35° CBN turning insert designed for hard turning applications and engineered to handle high abrasive loads in hardened steels

• CBN grade WBH20 for hard materials
• Rhombic 35° plate form for stable cutting
• 5° clearance angle for reduced cutting forces
• 0.8 mm corner radius for edge robustness

Consistent performance for hard turning operations

The insert is built around the CBN cutting material of the WBH20 grade, which is tailored to the demands of hardened steels. This composition provides high wear resistance and thermal stability, so repetitive passes maintain cutting geometry longer and machining results remain consistent. Using a CBN insert reduces downtime from frequent insert changes and supports higher cutting speeds where cemented-carbide solutions would wear prematurely, improving overall productivity and ensuring process reliability in serial production.

Geometry and chip control that stabilise the cut

The rhombic 35° plate form, combined with a 5° clearance angle and a 0.8 mm corner radius, gives a balanced compromise between strength and finishing capability. The specified chipbreaker (type 2) promotes reliable chip control under heavy conditions and helps to avoid re-cutting chips that could damage the workpiece. As an indexable insert, the design allows for quick indexing to a fresh cutting edge, reducing non-productive time and simplifying tool inventory management for hard machining tasks. The stable cutting edge and geometry are particularly effective where tight dimensional repeatability and surface quality are required.

Operational advantages and application guidance

In practical use, the insert offers longer edge life and predictable wear behaviour, which supports leaner tool-change schedules and fewer interruptions on the shop floor. The combination of CBN material and the chipformer design is beneficial when machining pre-hardened or hardened components, delivering lower variation between batches and fewer rejected parts. For application planning, recommend verifying coolant strategy and holder rigidity to maximise the life advantages of the insert. Technical cutting data and matched toolholders are available to help integrate the insert into existing tool systems while preserving part tolerances and surface integrity.

FAQ

Which materials is this insert best suited for?
The VBGW160408TM-2 WBH20 insert uses a CBN grade optimised for hardened steels; it is intended for hard turning and, depending on the specific workpiece alloy, can also be appropriate where high abrasive loads occur

How does the geometry influence cutting performance?
The rhombic 35° plate form, combined with a 5° clearance angle and a 0.8 mm corner radius, provides a strong cutting edge and improved chip flow; the chipbreaker type 2 enhances chip control under heavy cutting conditions

Is the insert compatible with standard 35° turning holders?
The insert follows the VBGW ISO form factor (rhombic 35°) and is intended for holders that accept that geometry; matching the correct clamping and seat type ensures optimal performance

What chip control and surface finish can be expected?
With the specified chipbreaker and the wear-resistant WBH20 grade, the insert promotes stable chips and consistent surface finish in hard turning, reducing the need for corrective finishing passes
