DNGA150404SM-S WCH10C — Indexable turning insert, coated ceramic for hardened steel | Walter Tools

The DNGA150404SM-S WCH10C is an indexable turning insert with a rhombic 55° profile, designed for high-speed hard turning and temperate-resistant machining of hardened steels.

• Coated ceramic grade WCH10C
• Optimised for hardened steels (ISO H)
• Rhombic 55° insert geometry
• 0° negative rake, 0.4 mm corner radius

Consistent edge life for hard machining

The coated ceramic formulation of this grade is engineered for demanding hard-turning applications, offering high thermal resistance and low flank wear under elevated cutting temperatures. Using a cutting-ceramic grade achieves longer tool life compared with conventional carbide when machining hardened steels, which reduces tool change frequency and contributes to more predictable production cycles. The result is measurable uptime improvement and a reduction in expenditure on replacement inserts.

Geometry that stabilises the process and improves surface finish

The rhombic 55° insert geometry and the 0.4 mm corner radius provide a balance between strength and accessibility in challenging cuts. With a 0° negative rake, the insert supports a controlled cutting action that favours process stability when facing high contact stresses. The designated chipbreaker S assists in forming short, manageable chips in interrupted or continuous cuts, which minimises the risk of workpiece damage and facilitates swarf evacuation—benefits that translate into improved surface quality and fewer interruptions on the machine.

Broad applicability and clear process advantages

Designed for the ISO H group, this insert is suitable for pre-hardened and hardened steels where wear resistance is critical. As an indexable insert from a recognised provider, it enables predictable performance and repeatable results across series production and small-batch hard machining alike. The combination of the WCH10C grade and the insert’s geometry supports higher cutting speeds and consistent dimensional stability, helping to increase throughput while maintaining target tolerances. For customers seeking reliable hard-turning solutions, this product represents a technical step towards greater process security and productivity.

FAQ

What materials is this insert intended for?
The DNGA150404SM-S WCH10C is intended for machining hardened steels (ISO group H), including pre-hardened conditions where wear resistance is required.

How does the 0° negative rake affect cutting behaviour?
A 0° negative rake gives a more robust cutting edge that improves stability under high contact forces; the WCH10C’s ceramic composition complements this by resisting thermal wear.

Which geometry benefits surface finish most?
The rhombic 55° geometry combined with a 0.4 mm corner radius helps to produce a consistent surface finish while maintaining edge strength during hard turning operations.

Is this insert suitable for interrupted cuts?
Yes, the insert’s geometry and the chipbreaker S are designed to assist in controlled chip formation, which is beneficial for interrupted and varying-cut conditions.

Can the DNGA150404SM-S WCH10C be used at elevated cutting speeds?
The WCH10C coated ceramic grade is formulated for high cutting speeds and temperature-resistant machining, making it appropriate where increased spindle speeds are employed.
