CNMG120408-MK5 WKP30S indexable turning insert, negative 0° geometry, Tiger·tec Silver – Walter Tools

The CNMG120408-MK5 WKP30S is an 80° rhombic indexable insert engineered for reliable roughing and medium-finishing in steel and cast iron applications.

• Tiger·tec Silver coated grade WKP30S
• Optimised for steel and cast iron
• Rhombic 80° shape, 0.8 mm corner radius
• Negative 0° geometry for stable cuts

Consistent productivity from the coating and grade

The combination of the Tiger·tec Silver coating with the WKP30S grade delivers improved wear resistance and predictable tool life under industrial turning cycles. Coating technology reduces flank wear and helps maintain a sharp cutting edge over longer runtimes, which translates into fewer tool changes and higher machine uptime. For operations sensitive to abrasive wear from cast materials, the coated substrate supports repeatable performance without compromising surface quality.

Robust chip control and secure edge for demanding cutting

Equipped with the MK5 chipbreaker and a 0° negative geometry, this insert promotes controlled chip formation and stable cutting forces during interrupted or heavy cuts. The chipbreaker geometry is designed to break and evacuate chips efficiently in both steel and cast iron, reducing the risk of chip re-cutting and improving process stability. The design supports higher feed rates where productivity gains are required while maintaining consistent dimensional accuracy.

Versatile geometry for diverse turning tasks

The rhombic 80° form with a 0.8 mm corner radius provides a balance between strength and accessibility in typical turning operations. The insert shape permits flexible tool positioning for facing, profiling and general turning, allowing single-index solutions for a variety of workpiece geometries. The negative rake angle enhances edge strength, making the insert suitable for tougher engagement conditions and extending service intervals in production environments.

Practical fit for production workflows

Delivered in the common CNMG format, the insert integrates with standard toolholders and tooling systems, facilitating quick changeover and inventory management. The M tolerance class and the specified thickness and size ensure repeatable seating and concentricity in toolholders. For procurement and planning, the insert supports a broad materials portfolio defined by ISO group P and K, meaning it is intended primarily for steel and cast iron machining tasks in both small-batch and continuous production.
