DCGW11T302TM-2 WBH20 – Indexable turning insert for hard turning (Walter Tools)

The DCGW11T302TM-2 WBH20 is an indexable turning insert engineered for hard-material turning, offering a robust CBN grade and geometry suited to precision finishing and wear-critical operations.

• CBN grade WBH20 for hard turning
• Rhombic 55° geometry for stable cuts
• 7° relief angle for reduced cutting forces
• 0.2 mm corner radius for fine surface finish

Consistent performance for hardened components

The combination of a CBN cutting material and the WBH20 grade provides exceptionally high wear resistance for machining hardened steels and comparable superalloys. This ensures longer effective life under elevated cutting temperatures and abrasive conditions, reducing tool changes and improving process uptime. The insert’s geometry is configured to maintain stable cutting even when tolerances and surface quality are critical, making it a reliable choice for series production of hardened shafts, bearing seats and similar components.

Geometry that improves chip control and surface quality

A Rhombic 55° shape paired with a defined chipbreaker and a 0.2 mm corner radius minimises vibration and supports consistent chip flow. The moderate radius helps to deliver a fine surface without sacrificing edge strength, while the chipbreaker setting (chipbreaker 2) is tuned for controlled segmentation under the higher cutting loads typical of hard turning. These attributes translate into reduced rework and a predictable finish, which is particularly valuable where downstream processes demand consistent part quality.

CBN technology tailored for hard machining

The WBH20 grade is part of the Walter CBN series and is specified for abrasive, high-hardness applications in accordance with the material group for hardened steels (ISO 513 — group H). As a superhard material, CBN offers thermal and wear resistance far beyond conventional carbides, allowing higher cutting speeds and stable performance when machining pre-hardened and through-hardened components. The indexable concept simplifies tool management: inserts can be indexed or replaced without regrinding, supporting efficient workshop routines and reliable cycle times.

FAQ

What materials is this insert suitable for?
The DCGW11T302TM-2 WBH20 insert is designed primarily for hardened steels (ISO 513 group H) and similar hard materials where CBN grades provide superior wear resistance.

How does the WBH20 grade differ from carbide inserts?
WBH20 is a CBN grade that offers significantly higher thermal and abrasive wear resistance than conventional carbide, enabling more stable performance and longer life in hard machining.

Which toolholders accept this insert geometry?
This rhombic 55° insert is compatible with standard turning toolholders designed for DCGW-style inserts; confirm the toolholder pocket matches the DCGW11T302TM-2 designation for secure clamping.

Is the 0.2 mm corner radius suitable for finishing operations?
Yes, the 0.2 mm corner radius balances edge strength with the ability to produce fine surface finishes, making it appropriate for semi-finishing to finishing passes in hardened components.

Can this insert be used for interrupted cuts?
While CBN inserts like WBH20 excel in continuous, high-wear applications, suitability for interrupted cuts depends on the specific workpiece and machining parameters; evaluation on the intended setup is recommended.
