DCGW11T302TS-2 WBH20C indexable turning insert – Walter Tools, CBN grade for hardened steel

The DCGW11T302TS-2 WBH20C is a CBN-coated indexable insert designed for hard turning and finishing of hardened steels within demanding production environments.

• Coated CBN for hard machining
• Rhombic 55° geometry for secure engagement
• 0.2 mm nose radius for fine surface finish

Optimised performance for hardened components

The insert delivers reliable wear resistance thanks to its coated CBN grade, which is specifically engineered for hardened steels and other high-wear applications. CBN, as a superabrasive, maintains cutting edge stability at high contact stresses and reduces flank wear compared with conventional carbides; this translates into longer tool life and fewer tool changes, improving process efficiency. The 55° rhombic geometry supports robust engagement and makes the component easier to programme for common turning operations, while the modest clearance angle assists consistent chip flow during hard machining.

Precision geometry that reduces rework and cycle time

A carefully selected 0.2 mm corner radius and the insert’s precise shape minimise vibration and help achieve repeatable surface quality, which reduces downstream finishing and inspection time. The combination of thin T3 thickness and the defined chipbreaker layout ensures predictable cutting behaviour in interrupted or continuous cuts, helping to protect the workpiece and the toolholder. These geometric characteristics support both rough turning under high forces and finishing passes where dimensional accuracy and surface integrity are required.

Application suitability and practical benefits

This indexable insert is intended for the hard machining of steels classified under ISO group H, including pre-hardened or through-hardened components. The WBH20C grade is optimised for stable chip formation and reliable performance in demanding alloys and heat-treated parts. For operations that demand consistent reproducibility and reduced downtime, the insert helps lower process costs through extended life and fewer interruptions. If toolholder compatibility is a concern, confirm clamping and seat dimensions with standard DCGW toolholder types to ensure correct fitment.

FAQ

What materials is this insert suitable for?
The DCGW11T302TS-2 WBH20C is formulated for hardened steels (ISO group H) and is suitable for pre-hardened components and challenging hard-turning tasks.

How does the CBN grade affect tool life?
Coated CBN provides superior wear resistance in hard materials, extending tool life and enabling longer uninterrupted production runs with consistent performance.

Is this insert appropriate for finishing passes?
Yes, the 0.2 mm corner radius and precise geometry make the insert well suited to finishing operations where surface quality and dimensional control are required.

Which insert geometry does DCGW indicate?
The DCGW form denotes a rhombic 55° insert profile suitable for a variety of turning approaches; the specified geometry offers a good balance between strength and accessibility.

Can this insert be used in interrupted cuts?
The insert’s robust grade and chipbreaker design support interrupted cutting, but recommended cutting data and holder rigidity should be checked to match the specific job.
