VBGW160408TM-2 WBH30 turning insert – CBN grade for hard turning (Walter Tools)

VBGW160408TM-2 WBH30 is a turning indexable insert designed for high‑wear applications in hard turning and the machining of hardened steels

• High‑wear CBN grade WBH30 for hard turning
• Rhombus 35° insert form for versatile clearance
• 5° relief angle for controlled cutting engagement

Consistent tool life through CBN hardness and grade benefits

The WBH30 grade is a CBN cutting material engineered for the demands of hardened steels. Its composition provides markedly improved wear resistance compared with conventional carbide grades, which means fewer insert changes and steadier component tolerances in long production runs. For operations where abrasion and elevated contact temperatures shorten tool life, the CBN composition delivers measurable gains in uptime and process repeatability.

Stable cutting geometry for predictable surface quality

The insert’s Rhombus 35° form together with a 5° relief angle and 0.8 mm corner radius yields a reliable contact geometry that reduces edge chipping and vibration. This geometry supports stable chip formation and consistent surface finish when facing or profiling hardened components. The controlled cutting engagement helps maintain dimensional accuracy over batch production, reducing downstream rework and inspection effort.

Designed for hard and pre‑hardened workpieces — what CBN provides

CBN inserts, as presented in this grade, excel where traditional inserts wear rapidly: grinding replacement, interrupted cuts or dry machining of hard grades. The WBH30 grade offers process security and predictable tool life when machining steels that have been heat treated. Because CBN works differently to carbide, thermal and mechanical stresses are managed at the cutting edge, which helps preserve the cutting geometry and lowers the risk of catastrophic flank wear.

Integration with tooling systems and operational advantages

The insert designation indicates a compact format (size 16, thickness 04) and a tolerance class G for interchangeability in standard insert holders. The combination of a robust grade, precise form and chipbreaker 2 supports higher productivity through longer tool life and fewer indexings. Where fixture stability and consistent feed strategies are in place, this insert contributes to reduced total machining cost per component and improved batch consistency.

FAQ

What materials is this insert intended to machine?
The insert is optimised for hardened steels and pre‑hardened steel applications; the WBH30 CBN grade is selected specifically for hard machining and wear‑intensive tasks.

What does WBH30 mean in practice?
WBH30 denotes a Walter Tools CBN grade developed for high process security and long wear life when machining hard materials; it balances edge strength with thermal stability.

How does the Rhombus 35° form affect machining?
The Rhombus 35° geometry provides flexible approach angles and effective clearance for turning and profiling operations while supporting stable cutting conditions.

Is the insert suitable for interrupted cuts or high temperatures?
Yes — the CBN composition of the WBH30 grade resists abrasion and maintains edge integrity under thermal stress, making it well suited to interrupted and elevated‑temperature applications.

Which designation should be quoted when ordering?
Quote the full designation and SKU: VBGW160408TM-2 WBH30 (SKU: VBGW160408TM-2-WBH30-WALTER) and specify the intended holder to ensure correct fitment.
