MPMT120408-F57 WKP35G indexable milling insert — Tiger·tec Gold coating (Walter Tools)

The MPMT120408-F57 WKP35G is a precision indexable milling insert engineered for productive machining of steel and cast iron, offering a balanced geometry for versatile finishing and semi-finishing applications.

• Tiger·tec Gold coating for extended tool life
• Grade WKP35G optimised for P and K materials
• 11° relief angle for secure cutting geometry
• 0.8 mm corner radius for repeatable edge strength

Consistent productivity through coated carbide technology

The insert combines a coated carbide substrate with the Tiger·tec Gold technology to deliver a high level of wear resistance and thermal stability during interrupted and continuous cuts. This results in reliable cutting performance across varying job profiles and reduces the frequency of tool changes, supporting higher machine utilisation. The geometry and coating together improve flank and crater wear behaviour, which translates into predictable component tolerances and fewer rework cycles.

Broad material capability reduces tool inventory

Designed for ISO groups P (steel) and K (cast iron), the grade WKP35G offers a practical compromise between toughness and hardness to handle the typical heat and chip formation of steels, while also resisting the abrasive nature of cast-iron chips. Using a single insert family for these materials simplifies tooling management and supports faster process setups, helping to lower total machining costs per component without sacrificing surface quality.

Geometry and edge preparation for repeatable results

The insert’s 11° relief angle and 0.8 mm corner radius are chosen to balance edge strength with the need for accurate profiles. The radius provides a robust leading edge for intermittent cuts and moderate feeds, while the relief supports secure seating in the cutter pocket, reducing vibration and the risk of chipping. Tolerance class M ensures consistent fit and interchangeability across holder systems, enabling quick insert changes and consistent runout behaviour.

Practical advantages on the shop floor

With chipbreaker designation F57 and a compact plate format, this insert is suited to a wide range of pocket geometries and cutter bodies used in modern CNC milling. The combination of grade and chip control reduces edge build-up and improves swarf evacuation, which helps maintain surface finish and increases cycle stability. For applications requiring predictable tool life and stable results, this insert contributes directly to process reliability and up-time improvement.

FAQ

What materials is this insert suitable for?
The WKP35G grade is designed specifically for steel (ISO group P) and cast iron (ISO group K), enabling machining of both material families with consistent wear behaviour.

How does the Tiger·tec Gold coating affect tool life?
The Tiger·tec Gold coating increases thermal resistance and wear protection, meaning the insert maintains cutting edge integrity longer under typical milling conditions.

Which geometry parameters support stable cutting?
The combination of an 11° relief angle and a 0.8 mm corner radius gives the insert the balance between edge strength and dimensional accuracy needed for repetitive milling tasks.

Is this insert compatible with standard MPMT toolholders?
The insert designation matches common MPMT-style pockets; tolerance class M ensures secure seating and interchangeability across compatible cutter bodies.
