CNMG120408-MP5 WPP10G — indexable turning insert for steel by Walter Tools

CNMG120408-MP5 WPP10G is a negative‑lead, rhombic 80° turning insert designed for productive steel machining in serial production.

• Tiger·tec Gold coating for extended tool life
• MP5 chipbreaker for controlled chip formation
• 0.8 mm nose radius for stable finishing
• Rhombic 80° insert, negative 0° lead angle

High productivity through robust coating and geometry

The combination of the Tiger·tec Gold coating and a purpose‑designed insert geometry increases process stability and wear resistance. Through a hard, wear‑resistant surface layer, the grade reduces flank wear and allows longer uninterrupted cutting times, which results in fewer tool changes and higher machine utilisation. This contributes directly to improved throughput in turning operations on steel and lowers unit production cost without compromising repeatability.

Predictable chip control and surface quality

Equipped with the MP5 chipbreaker, this insert ensures reliable chip formation across common steel grades, improving evacuation and reducing risk of re-cutting. The controlled chip flow leads to consistent surface finish and decreases downtime caused by manual chip clearing. For customers requiring reproducible part quality, the geometry supports steady cutting forces and predictable tool behaviour in finishing and medium‑depth turning.

Application range and material suitability

The insert is specified for machining steel (ISO group P) and is optimised for typical thermal and metallurgical conditions encountered when turning unalloyed and alloyed steels. The 0.8 mm nose radius balances edge strength and detail reproduction, making the insert suitable for both light finishing cuts and moderate roughing where dimensional stability is required. The negative 0° lead angle improves edge strength under interrupted cuts and heavy engagement.

Integration into production and handling benefits

As a standard CNMG‑format insert, it integrates easily into common toolholders and turret systems, simplifying inventory and tool change procedures. The robust tolerance class and consistent grade properties support reliable indexation and repeatable clamping, contributing to lower scrap rates and predictable maintenance intervals. Components benefit from fewer process variances and a smoother workflow on the shop floor.
