CNMM190624-HU7 WPP20G — Turning indexable insert, Tiger·tec Gold, for Stahl (Walter Tools)

the CNMM190624-HU7 WPP20G is a precision turning indexable insert designed for general turning of Stahl, offering a coated carbide grade and a dedicated chipbreaker for reproducible results

• Tiger·tec Gold coating for extended tool life
• WPP20G grade optimised for Stahl
• Rhombus 80° insert geometry
• HU7 chipbreaker for consistent chips
• 0° (negative) relief for robust cutting

High process reliability through coated-grade performance

The combination of the Tiger·tec Gold coating with the WPP20G grade delivers a measurable increase in wear resistance and machining stability when facing the thermal loads typical of Stahl turning. As a coated carbide solution, this insert reduces flank wear and maintains a stable cutting edge over longer tool lives, which in turn supports more predictable tool-change intervals and higher uptime. The result is tangible: fewer interruptions, consistent part quality and improved productivity in serial and batch production.

Stable chip formation and surface quality with HU7 chip control

Equipped with the HU7 chipbreaker and a 0° (negative) relief configuration, the insert ensures controlled chip formation even under interrupted cuts and variable feed conditions. The rhombus 80° geometry provides flexibility for a range of turning operations, while the corner radius 2.4 contributes to surface finish and edge strength. These features combine to offer reliable chip evacuation and reduced risk of built-up edge, which benefits both workpiece integrity and downstream processes.

Practical handling and application benefits for the workshop

The insert’s format and grade simplify tool selection for operations focused on Stahl: a coherent grade concept reduces set-up complexity and supports repeatable results across different machines. Walter Tools’ WPP20G sort stands out for a balanced combination of wear resistance and toughness, making it suitable for a broad spectrum of turning tasks.

FAQ

What materials is this insert intended for?
The CNMM190624-HU7 WPP20G is designed primarily for machining Stahl; the WPP20G grade and Tiger·tec Gold coating are optimised for typical steel cutting conditions.

How does the HU7 chipbreaker affect machining?
The HU7 chipbreaker on this insert controls chip formation to produce consistent chip shapes, which improves evacuation and reduces the chance of built-up edge when turning Stahl.

What are the benefits of the 0° (negative) relief angle?
A 0° (negative) relief increases cutting-edge strength and stability under heavy or interrupted cuts; this configuration supports robust performance in demanding turning operations.

Which geometry suits general turning tasks?
The rhombus 80° geometry offers versatility for a wide range of turning applications, combining effective cutting access with safe insert indexing.

Is the WPP20G grade suitable for high-speed cutting?
WPP20G, with its Tiger·tec Gold coating, provides enhanced wear resistance and thermal stability, which contributes to reliable performance at elevated cutting speeds for Stahl.
