VCMT160408-MP4 WPP20G – Walter Tools turning insert, Tiger‑tec Gold, Rhombic 35°, 7° clearance

The VCMT160408-MP4 WPP20G is a rhombic 35° indexable turning insert designed for general Stahl machining, offering balanced toughness and wear resistance for a wide range of turning operations.

• Tiger‑tec Gold coating for long life
• Optimised MP4 chipbreaker for stable chips
• Rhombic 35° geometry for versatile turning
• 0.8 mm corner radius for durable edge

Greater productivity through a high-performance coating

The combination of the Tiger‑tec Gold coating with the WPP20G carbide grade provides measurable benefits in everyday production. The coating reduces flank and crater wear, while the substrate is tuned for balanced toughness and hardness, which together improve wear resistance and extend effective tool life. For general-purpose turning in Stahl, this results in fewer insert changes and more stable cycle times. The outcome is predictable performance and a reduced overall cost per part when compared with uncoated or lower‑grade alternatives.

Reliable chip control and consistent surface quality

The dedicated MP4 chipbreaker is engineered for stable chip formation across common cutting conditions encountered in turning. Combined with the Rhombic 35° geometry and the modest 7° clearance angle, it supports controlled chip flow and reduced vibration, producing a consistent surface finish. In practical terms, the geometry minimises cutting forces during interrupted cuts and offers better access in turning shoulders and profiles, which helps maintain dimensional integrity and lowers downstream rework.

Robust edge security and dimensional stability

Tolerance class M and a 0.8 mm corner radius provide a secure cutting edge that tolerates moderate variations in feed and material infeed without premature edge breakdown. The insert thickness and seat design ensure repeatable clamping and indexing, contributing to process stability in interchangeable toolholders. For operations where edge robustness and repeatability are priorities, the combination of radius, tolerance and coating delivers fewer edge‑related rejects and longer intervals between quality checks.

Broad applicability and economic machining strategy

Designed for the ISO P group, the insert is suitable for unalloyed and alloyed Stahl commonly used in parts production. Its balanced character—neither overly hard nor excessively tough—makes it versatile for a range of turning tasks, from finishing to medium‑depth roughing when cutting data is adapted accordingly. Employing this insert as part of a standardised tooling setup supports consistent cycle times and simpler inventory management, yielding better overall process economics.
