CNMG120412-MK5 WKP30S — Indexable turning insert, Tiger‑tec Silver, for steel and cast iron (Walter Tools)

The CNMG120412-MK5 WKP30S is a rhombic 80° indexable turning insert designed for reliable machining of steel and cast iron in general turning applications.

• Tiger·tec Silver coating for stable cutting
• Optimised MK5 chipbreaker for consistent chips
• Negative 0° geometry for robust machining
• 1.2 mm corner radius for improved edge strength

Longer service life through advanced coating and grade

The Tiger‑tec Silver coating combined with the WKP30S coated‑carbide grade provides improved wear resistance and stable cutting behaviour when machining both steel and cast iron. This combination reduces flank and crater wear under typical turning conditions and helps to extend tool life, lowering changeover frequency. The coated surface also supports consistent performance across batch runs and contributes to predictable production output.

Consistent chip control for reliable machining

An optimised MK5 chipbreaker and the negative geometry with a 0° clearance produce controlled chip formation in a wide range of turning operations. Controlled chips reduce the risk of entanglement and protect the cutting edge, which in turn preserves surface quality and minimises interruptions. The insert’s chip management is particularly beneficial when dealing with variable material batches or mixed part runs where repeatability matters.

Robust geometry for heavy use and edge security

The rhombic 80° shape with a 1.2 mm corner radius delivers a balance between edge strength and accessibility in shoulder and profiling cuts. The negative 0° configuration increases radial support at the cutting edge, making the insert well suited to more demanding cuts and interrupted operations. Tolerance class M ensures consistent fit in standard toolholders and supports repeatable indexation during tool changes.

Productivity and process stability in production environments

Designed for industrial turning, the insert supports efficient workflows by combining wear‑resistant materials with dependable geometry; this lowers the total cost of ownership through fewer tool changes and more consistent machining cycles. Compatibility with ISO material groups P (steel) and K (cast iron) means a single grade can be applied across multiple workpiece families, simplifying tool logistics on the shop floor and improving setup times.

Application notes and practical considerations

The insert suits a broad spectrum of turning tasks where a balance of durability and chip control is required. While the grade is optimised for steel and cast iron, actual cutting data depends on machine capability, holder rigidity and workpiece condition; consult technical data for recommended feeds and speeds. Proper clamping in an appropriate negative‑geometry holder will ensure the best performance from the Tiger‑tec Silver grade and the MK5 chipbreaker.

FAQ

What materials is this insert suitable for?
The CNMG120412‑MK5 WKP30S insert is designed for steel (ISO group P) and cast iron (ISO group K) machining.

How does the Tiger‑tec Silver coating help?
Tiger‑tec Silver on the WKP30S grade improves wear resistance and thermal behaviour, which enhances tool life and process stability when using the CNMG120412‑MK5 insert.

What machining operations benefit most from this insert?
The insert is suitable for general turning where robust edge security and reliable chip control are required; its negative geometry supports interrupted cuts and heavier radial engagements.

Which chipbreaker is integrated and what is its advantage?
The MK5 chipbreaker delivers consistent chip formation and evacuation, reducing manual intervention and supporting improved surface finish with the Walter Tools insert.
