CNMG120412‑MS3 WPP20G — Rhombic 80° turning insert, Tiger·tec Gold coating (Walter Tools)

The CNMG120412‑MS3 WPP20G is a rhombic 80° turning insert designed for efficient general-purpose steel turning, offering a balanced mix of wear resistance and reliable chip control.

• CNMG shape, 80° rhombus insert
• Tiger·tec Gold coating for steel
• MS3 chipbreaker for controlled chips
• 0° negative rake, 1.2 mm corner radius

Optimised performance for steel machining with Tiger·tec Gold

The CNMG120412‑MS3 WPP20G insert combines the Tiger·tec Gold coating technology with the proven WPP20G grade to deliver improved resistance to abrasive and adhesive wear during steel machining. The MS3 chipbreaker is engineered for predictable chip formation under common turning conditions, reducing interruptions for chip clearance and improving process stability. With a 0° negative rake, the insert supports robust cutting when encountering interrupted cuts or harder workpiece zones, while the 1.2 mm corner radius adds edge strength for longer service life. These characteristics translate into a measurable increase in uptime and consistent productivity on turning centres.

Better surface finish and chip control for steady production

Controlled chips and a stable cutting edge make a direct contribution to surface quality and repeatability. The MS3 geometry helps to break and evacuate chips efficiently, which reduces the risk of chip re-cutting and minimises surface defects. The rhombic 80° form ensures flexible approach angles for diverse turning tasks, allowing for effective roughing and finishing with the same geometry. Together, these features reduce the need for frequent tool changes and support a steady production rhythm on medium- to high-duty steel components.

Coating and grade for longer tool life and consistent results

The insert’s WPP20G grade, integrated into the Tiger·tec Gold series, is designed to offer a balanced combination of wear resistance and toughness for steel applications. This coating system supports higher thermal stability and reduced flank wear over extended cutting intervals, while the tolerance class M ensures repeatable fit and performance across toolholders. The result is a tool that maintains dimensional reliability and surface integrity over multiple tool life stages, helping to lower total machining costs through fewer interruptions and predictable regrinds.

Practical selection, mounting and application guidance

The CNMG form and the standard CNMG120412‑MS3 designation make the insert easy to match with common toolholders and clamping systems. Key parameters to note are the 12 insert size, plate thickness 04, 0° negative rake, and the 1.2 mm corner radius; these determine appropriate cutting data and feed choices for steel (ISO P) machining. For integrated process planning, pairing this insert with stable toolholders and optimised cutting parameters will maximise the benefits of the coating and chipbreaker.
