CNMG160612-MK5 WKP30S — Indexable turning insert, Tiger·tec Silver coating (steel & cast iron) by Walter Tools

The CNMG160612-MK5 WKP30S is an 80° rhombic indexable turning insert optimised for machining steel and cast iron in industrial turning applications

• Tiger·tec Silver coating for high process reliability
• WKP30S grade for steel and cast iron machining
• Rhombic 80° geometry with 0° negative rake
• MK5 chipbreaker for controlled chip formation

Improved process reliability through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WKP30S carbide grade delivers a balance of wear resistance and heat management that is particularly effective for continuous production. Coated carbide reduces flank and crater wear by providing a thermally stable surface, which translates into more predictable tool life and fewer unplanned tool changes. This behaviour is especially important in batch production, where reproducible cutting performance lowers cycle-time variability and supports consistent component quality.

Geometry and chip control that enhance surface finish and stability

The insert’s rhombic 80° form and 0° (negative) free angle create a robust cutting edge that resists vibration and maintains geometry during interrupted cuts. A corner radius of 1.2 mm helps achieve improved surface integrity and dimensional stability at moderate radial depths. The MK5 chipbreaker promotes reliable chip segmentation and evacuation, reducing the risk of built-up edge and helping to maintain consistent surface finish over long runs.

Predictable tool life and simplified planning for production shops

Using a grade tuned for both ISO P (steel) and ISO K (cast iron) workpieces ensures versatility in mixed production environments. The coated grade and chipbreaker combination support longer usable life per edge, which reduces changeover frequency and contributes to lower cost per part. For process planning, recommend testing starting parameters from similar insert geometries in catalogue data and then adapting feeds and speeds for the specific machine–workpiece–fixture combination. If uncertainties arise regarding suitability or cutting data, Metav Werkzeuge provides application advice and cutting parameter support via email or phone.

Application guidance and material suitability explained

The insert is designated for machining steel and cast iron in accordance with the intended material groups (ISO P and ISO K). The designation and series indicate a catalogue- and geometry-dependent main application, so final cutting values may vary with workpiece alloy and hardness. The moderate corner radius and negative rake make the insert a solid choice for general turning tasks that demand robust edge protection and consistent chip breaking rather than ultra-fine finishing cuts. For catalogue-based recommendations and sample cutting data, consult the manufacturer specifications or Metav Werkzeuge’s technical team.
