WNMG080408-RM5 WNMG080408-RM5 WPP20G – indexable turning insert for steel, Walter Tools

WNMG080408-RM5 WPP20G is an indexable turning insert designed for reliable steel machining with Tiger·tec Gold coating.

• Tiger·tec Gold coating for high wear resistance
• Grade WPP20G optimised for steel machining
• Trigon 80° insert with 0.8 mm corner radius
• Negative 0° geometry with RM5 chipbreaker

Consistent performance for steel turning operations

The combination of the WPP20G grade and the Tiger·tec Gold series provides a balanced performance profile tailored to steel machining. The coated cemented carbide composition offers a compromise between wear resistance and toughness, which reduces flank and crater wear under typical turning conditions. For production environments seeking predictable tool life and repeatable part quality, this geometry promotes stable cutting forces and controlled heat management, thereby improving process reliability and lowering unexpected downtime.

Geometry and chip control that simplify setup

With an 80° trigon shape and a 0.8 mm corner radius, the insert delivers a versatile edge for a range of turning tasks, from light finishing to medium roughing. The RM5 chipbreaker is engineered to form short, controlled chips when machining steel, reducing the risk of chip entanglement and improving surface integrity. The negative 0° rake provides a robust cutting edge that better resists edge chipping in interrupted cuts or unstable clamping conditions, making the insert suitable for demanding turning operations in mixed-production shops.

Productivity gains through material and coating technology

The Tiger·tec Gold coating technology increases resistance against abrasive wear while maintaining a resilient substrate layer underneath. This results in longer intervals between index changes and fewer tool interventions on the machine. The WPP20G grade is identified as a versatile option across ISO group P (steel), offering an attractive balance of economy and performance for batch production and job-shop environments where tool change frequency directly impacts throughput.

Practical selection and application guidance

When selecting cutting parameters, prioritise stable clamping and appropriate feed rates to leverage the insert’s geometry and chipbreaker design. The WNMG080408-RM5 WPP20G insert performs well in typical steel alloys and can be integrated into existing tool holders that accept WNMG-format inserts. For customers requiring assistance with parameter settings, toolholder compatibility or process optimisation, Metav Werkzeuge offers technical consultation to ensure the insert is applied for maximum efficiency and repeatable part quality.
