SNGN120408TM-S WBK30 Wendeplatten - Walter Tools

Benefit from the CBN cutting performance of the WBK30 grade, the reproducible edge life of a square 90° format with a 0.8 mm corner radius, and the stability afforded by a negative 0° relief for demanding, hardened-material turning — order directly via Metav Werkzeuge or contact their consultants for application advice.

SNGN120408TM-S WBK30 – Square 90° CBN indexable turning insert, 0.8 mm corner radius (Walter Tools)

The SNGN120408TM-S WBK30 is a square 90° indexable turning insert in a CBN grade, engineered for heavy‑duty finishing and machining of hardened steels and other highly abrasive materials.

• CBN grade WBK30 for hardened steels
• Square 90° insert for robust turning
• Negative 0° relief for stable cutting
• 0.8 mm corner radius for defined edge

Dependable cutting life for hardened and high‑wear tasks

The SNGN120408TM-S WBK30 combines the abrasion resistance of CBN with a geometry designed to maintain edge integrity in high‑stress applications. The WBK30 grade is intended for machining hardened steels and, depending on the material matrix, certain castings or superalloys; this results in extended service life and fewer insert changes, which lowers tool‑room downtime and increases machine uptime. For precise matching of grade to component material, consult the product matrix supplied by the manufacturer.

Secure geometry for repeatable surface quality

A square 90° outline and 0.8 mm corner radius create a robust cutting edge that tolerates higher radial loads while producing consistent surface finish. The negative 0° relief provides a compact cutting geometry that reduces vibration and improves seat stability in the tool holder, yielding predictable cutting forces and repeatable part tolerances. The integrated chipbreaker S supports controlled chip formation and evacuation during finishing passes, which helps to protect the workpiece and toolholder.

Process efficiency and selection guidance

Using a CBN grade such as WBK30 typically leads to higher process security and longer intervals between regrinds or insert changes, particularly when machining hardened components. This enhances productivity and supports cost‑effective batch production. Selection remains application‑specific: check the material suitability against the product matrix and consider machine rigidity, clamping and coolant strategy when integrating this insert into an existing process. For tailored recommendations on cutting data and optimal toolholder pairing, technical consultation is advised.

FAQ

Which materials is this insert suitable for?
The WBK30 CBN grade is primarily intended for hardened steels and, depending on the specific product matrix, may be suitable for certain castings or superalloys; confirm suitability for the intended material before use.

What does the designation WBK30 indicate?
WBK30 denotes Walter Tools’ CBN cutting grade optimised for hard, highly abrasive machining conditions and stable wear behaviour.

How does the negative 0° relief affect performance?
A negative 0° relief increases cutting edge strength and seat stability, which improves process security when using the SNGN120408TM-S WBK30 insert in heavy or interrupted cuts.

What is the function of the chipbreaker S?
The chipbreaker S is designed to produce controlled chip forms during finishing operations, aiding chip evacuation and protecting the workpiece surface.

Is the 0.8 mm corner radius suitable for finishing?
A 0.8 mm radius offers a balance between edge strength and surface finish; it is well suited to finishing and semi‑finishing operations where repeatable geometry is required.
