DNGA150612TS-2 WBK20 indexable turning insert by Walter Tools — CBN grade for hard materials

the DNGA150612TS-2 WBK20 is an indexable turning insert designed for demanding hardened-steel applications and heavy-wear tasks, combining a CBN cutting grade with a robust rhombic 55° geometry

• CBN cutting grade WBK20 for hardened materials
• 55° rhombic form for versatile turning
• 0° negative rake for stable cutting
• 1.2 mm corner radius for robust edge strength

Consistent material removal and predictable tool life

The combination of the CBN cutting grade WBK20 and the rhombic 55° geometry delivers high process stability during hard turning. CBN is especially suited for abrasive, hardened steels and similar hard materials; its microstructure provides a wear-resistant cutting edge that reduces flank wear and extends productive life. The 0° negative rake enhances mechanical strength at the cutting edge, enabling stable chip formation under interrupted cuts. These technical choices translate into fewer tool changes and more consistent batch throughput, supporting predictable cycle times and lower overall machining costs.

Improved edge strength and surface integrity

A 1.2 mm corner radius and the specified chipbreaker ensure a robust cutting edge and controlled chip flow. The larger corner radius reduces local stress concentration at the cutting tip and improves surface finish in finishing and semi-finishing passes. The chipbreaker configuration promotes short, manageable chips for turning operations, which benefits tool life and helps maintain workpiece integrity. For production environments where repeatability and surface quality matter, these geometric features combine to reduce rework and support higher first-pass yields.

Integration into tool systems and process planning

The insert follows established indexable turning conventions, allowing straightforward integration with compatible toolholders and tool-setting routines. The plate thickness code and insert form are consistent with common turning systems, simplifying tool inventory management. Process planners gain from the WBK20 grade’s focus on wear resistance: machining strategies for hardened components can be optimised around predictable tool-change intervals. When selecting cutting parameters, consider the workpiece material class and consult the product matrix for best-fit cutting data to achieve the intended performance.

Application suitability and validation

This insert targets operations where hard materials and high wear conditions are the norm: hardened-steel components, certain castings and superalloy tasks (where applicable). Material suitability should be checked against the manufacturer’s product matrix to ensure the best match of grade and cut. The insert’s combination of CBN technology and robust geometry supports both high-throughput production and challenging one-off repair or refurbishment jobs where edge durability is decisive.

FAQ

What materials is this insert intended for?
The DNGA150612TS-2 WBK20 insert from Walter Tools is a CBN grade designed primarily for hardened steels and high-wear tasks; suitability for specific alloys or castings should be verified in the manufacturer’s material matrix.

How does the 0° negative rake affect cutting performance?
A 0° negative rake increases edge strength and resistance to mechanical shock, making the insert suitable for robust cutting conditions and intermittent cuts without sacrificing process stability.

What benefit does the 1.2 mm corner radius provide?
The 1.2 mm corner radius improves edge robustness and contributes to a better surface finish in finishing passes while reducing the likelihood of premature chipping under heavy loads.

Is the insert compatible with standard tooling systems?
The DNGA150612TS-2 form and codes conform to common indexable turning standards, allowing integration with compatible toolholders; toolholder selection should follow the holder manufacturer’s recommendations.
