CCMT120412-MW4 WPP20G turning insert — Tiger·tec Gold coated, for steel machining (Walter Tools)

CCMT120412-MW4 WPP20G is an indexable turning insert designed for precision steel machining, combining a Tiger·tec Gold coated carbide grade with a rhombic 80° form for consistent chip formation and extended tool life

• Tiger·tec Gold coating for stable cutting performance
• Designed for steel machining (ISO group P)
• Rhombic 80° form with 7° relief angle
• 1.2 mm corner radius for reliable edge strength

Improve process reliability with advanced coated carbide

The Tiger·tec Gold coating and the Walter Tools carbide substrate deliver a balance between wear resistance and toughness. This combination reduces flank and crater wear under typical steel cutting temperatures, resulting in a more consistent tool life and fewer tool changes per shift. The coated structure is engineered to support stable chip formation, which lowers the risk of built-up edge and unexpected downtime. Specified as a coated carbide grade, the insert suits production environments where repeatable results and lower machining variation are essential.

Geometry focused on surface quality and dimensional control

With a rhombic 80° outline, a 7° free angle and a 1.2 mm corner radius, the insert geometry supports controlled cutting forces and predictable engagement with the workpiece. The positive rake and relief geometry minimise vibration and help produce a consistent surface finish, while the corner radius provides edge strength for interrupted cuts. These features translate into fewer rework operations and improved dimensional stability on turned components, particularly when repeatable finishes are critical to downstream processes.

Versatile performance across common steel grades

Assigned to ISO group P, the grade is tailored for machining unalloyed and alloyed steels, covering a spectrum from wear-resistant to tougher steel conditions. The Walter Tools WPP20G grade is positioned as a universal option within the Tiger·tec Gold family, enabling one insert to serve multiple applications and reducing inventory complexity. For production planners, this means fewer variant tools on the shelf and easier tool selection, while operators benefit from a predictable cutting response when switching between similar steel families.

Practical integration for workshop and production use

The CCMT form fits standard toolholders designed for this insert designation and is supplied in a tolerance class M, ensuring consistent seating and repeatable clamping performance. The designation indicates a proven balance between manufacturing tolerances and economical production. The insert thickness code and size provide compatibility with commonly used turning tool carriers in industrial turning centres. For implementation, machine setup should consider the recommended cutting data for steel with coated carbide inserts to achieve the best wear behaviour and surface results.

FAQ

What materials are suitable for this insert? The CCMT120412-MW4 WPP20G turning insert is intended for machining steel and is classified for ISO group P, covering unalloyed and alloyed steels.

How does the Tiger·tec Gold coating benefit production? Tiger·tec Gold on the WPP20G grade improves wear resistance and supports stable chip formation, which enhances tool life and process consistency in steel turning operations.

What is the significance of the 1.2 mm corner radius? A 1.2 mm corner radius provides a stronger cutting edge that tolerates interrupted cuts and reduces edge chipping while helping to maintain surface integrity.

Is this insert compatible with standard CCMT toolholders? The insert follows the CCMT designation and fits toolholders designed for CCMT inserts; its tolerance class M supports consistent seating and repeatable clamping.

Which chipbreaker is integrated and what is its purpose? The insert uses the MW4 chipbreaker, which is engineered to produce controlled chips and improve evacuation during turning of steel materials.
