CNMG120408-RM5 WPP10G turning indexable insert — for steel machining, Tiger‑tec Gold, RM5 | Walter Tools

CNMG120408‑RM5 WPP10G is a negative‑rake turning insert engineered for reliable steel machining and consistent chip formation

• Tiger‑tec Gold coating for high wear resistance
• Optimised RM5 chipbreaker for stable chips
• Rhombic 80° form with 0.8 mm corner radius
• Designed for steel machining (ISO P), tolerance M

Longer tool life through advanced coating and grade

The Tiger‑tec Gold coating paired with the WPP10G carbide grade delivers improved resistance against abrasive wear and thermal loading. This combination reduces flank wear under cyclic cutting conditions and extends productive tool life, which translates into fewer insert changes and lower process interruptions. The coated microstructure also helps maintain cutting‑edge integrity during interrupted cuts, offering a measurable advantage in batch turning and mixed‑load operations.

Predictable chip control and stable cutting performance

Fitted with the RM5 chipbreaker, the insert produces compact, controllable chips when cutting steels in the ISO P group. The chipformer geometry is designed to guide chips away from the tool and workpiece, reducing the risk of re‑cutting and machine downtime. The negative rake at 0° stabilises the cutting edge under higher feed rates, improving dimensional consistency and surface finish in medium to heavy turning tasks.

Geometry optimised for accurate finishes and repeatability

The Rhombic 80° form combined with a 0.8 mm corner radius provides an excellent balance between strength and accessible cutting edge for finishing and medium‑roughing operations. Tolerance class M ensures repeatable insert dimensions for predictable toolholder fit and process stability. These geometric features support a wide range of turning strategies while simplifying insert selection across common steel turning applications.

Application focus and production benefits

Specifically designed for machining steel (ISO P), this insert supports steady productivity with reliable edge life and consistent surface quality. The robust design and coating technology make it suitable for short‑to‑medium tool engagements where a combination of wear resistance and toughness is required. As a consequence, cycle times can be optimised without sacrificing component accuracy, helping to lower cost per part in series production.
