CNMG190612-RP5 WPP20G — Indexable turning insert, Tiger·tec Gold, for steel | Walter Tools

The CNMG190612-RP5 WPP20G is a rhombic 80° indexable turning insert engineered for general steel turning, offering a balance of wear resistance and toughness for reliable production use.

• Tiger·tec Gold coating for extended tool life
• WPP20G coated carbide grade for steel machining
• RP5 chipbreaker for reliable chip control
• Rhombic 80° form with 1.2 mm nose radius

High-performance coating and grade for predictable tool life

The combination of Tiger·tec Gold coating and the WPP20G grade provides a coated carbide construction that is optimised for the thermal and mechanical demands of machining steel. This engineered coating reduces wear mechanisms while retaining edge stability, which results in longer tool life and fewer index changes in series production. The result is an insert that supports consistent cycle times and predictable maintenance intervals, contributing to improved process reliability and lower overall production costs.

Geometry and chip control for safer, cleaner cutting

Designed with an RP5 chipbreaker and a rhombic 80° form, the insert promotes controlled chip formation and efficient evacuation during turning operations. The 1.2 mm nose radius helps to maintain surface integrity while allowing for moderate engagement in finishing and medium cutting tasks. The 0° (negative) clearance contributes to a robust cutting edge, making the insert suited to stable turning setups and interrupted cuts where edge security is critical.

Application scope and operational advantages in practice

Specified for the ISO group P, this indexable turning insert is tailored to the machining of unalloyed and alloyed steel, delivering a practical compromise between wear resistance and toughness for a broad range of turning applications. The tolerance class M indicates consistent manufacturing accuracy, enabling repeatable seating and predictable performance across multiple toolholders. For production environments seeking reproducibility and straightforward tool inventory management, the insert delivers a compact solution that is simple to adopt into existing turning cycles.

FAQ

What materials is this insert suited for?
The CNMG190612-RP5 WPP20G insert from Walter Tools is specified for ISO group P and is therefore suited to machining unalloyed and alloyed steel.

How does the Tiger·tec Gold coating benefit production runs?
The Tiger·tec Gold coating on the WPP20G grade reduces wear and improves thermal resistance, which extends service life and results in fewer tool changes during extended production.

Which geometry features assist with chip control?
The RP5 chipbreaker combined with the rhombic 80° form and a 1.2 mm nose radius supports reliable chip formation and evacuation for cleaner, safer turning operations.

Is the insert robust enough for interrupted cuts?
The negative 0° clearance and the WPP20G coated carbide construction provide a robust cutting edge that is well suited to interrupted cuts and heavier engagement in stable setups.

Can this insert be used for finishing and medium cutting?
Yes, the geometry and grade are optimised to perform in both finishing and medium turning operations on steel, offering a balance between surface quality and tool life.
