VCMT160412-RP4 WPP20G — Indexable turning insert, Tiger‑tec Gold coating, for Stahl | Walter Tools

The VCMT160412-RP4 WPP20G is an indexable turning insert engineered for precision turning of Stahl, combining a robust rhombic geometry with a dedicated RP4 chipbreaker for reliable chip control.

• Tiger‑tec Gold coated carbide grade WPP20G
• RP4 chipbreaker for stable chip control
• Rhombic 35° profile with 1.2 mm corner radius
• Optimised for Stahl machining

Consistent productivity through an optimised cutting grade

The coated carbide WPP20G in the Tiger‑tec Gold series is specified for reliable performance when machining Stahl according to ISO 513. The combination of a wear-resistant coating and a formulation tuned to typical heat and chip characteristics of Stahl results in stable chip control and consistent cutting results. For production environments this stability reduces cycle-time variability and contributes to a predictable process window, supporting uninterrupted machining and fewer insert changes.

Extended tool life from advanced surface engineering

The insert’s coated carbide construction provides enhanced resistance against abrasive and adhesive wear mechanisms encountered in turning operations. The Tiger‑tec Gold technology is designed to protect the cutting edge, which translates into longer tool life and fewer interruptions for index changes. This durability supports higher uptime and improved cost-efficiency per component produced, particularly in medium- to high-volume machining of plain and alloyed Stahl.

Geometry and chipbreaker designed for edge stability and surface finish

The rhombic 35° profile with a 1.2 mm corner radius delivers a good balance between edge strength and accessibility for versatile turning tasks. The RP4 chipbreaker promotes favourable chip formation and evacuation, helping to avoid entanglement and tool nose damage. The insert’s 7° clearance angle supports a stable cutting edge contact and contributes to a consistent surface finish, especially in semi-finish and finish passes where dimensional control matters.

Practical application advice and machinability overview

This indexable insert is optimised for the ISO P group and suited to a broad range of Stahl materials, from unalloyed to alloyed grades. Tolerance class M indicates a standard precision suited to general turning tasks. The insert performs well in both continuous and interrupted cuts when paired with a suitable turning holder and correct clamping. For best results, match the RP4 chipbreaker with the intended depth of cut and feed range, and monitor wear progression to schedule timely indexing and replacement.
