Consistent performance from Tiger·tec Gold for longer tool life

The SNMM250924-HU7 WPP20G is manufactured with the Tiger·tec Gold coating technology, a multi-layer CVD/PVD approach that increases wear resistance and thermal stability under typical steel cutting conditions. This coating reduces flank wear and preserves the cutting edge at higher temperatures, which translates into longer intervals between index changes and fewer tool interventions on the machine. The result is improved uptime and lower production costs per part while maintaining a predictable tool life in serial or batch operations.

Reliable chip control and stable cutting with HU7 geometry

The combination of the HU7 chipbreaker and a negative 0° rake creates a robust cutting condition that helps to control chip shape and evacuation when machining steels (ISO P). The HU7 geometry is engineered to break and curl chips reliably under varying depths of cut, reducing the risk of entanglement and minimising secondary operations to clear swarf. This leads to a safer, more reproducible machining process and supports higher metal removal rates where stable chip flow is required.

Geometry and dimensions that favour productivity and cost-efficiency

The insert’s square 90° form with a corner radius of 2.4 mm and a nominal size of 25 mm provides a solid edge strength suitable for medium to heavy turning tasks. With a thickness of 9 mm, the insert offers rigidity and resistance to deflection, which is beneficial for interrupted cuts or heavier feed rates. The square geometry also allows multiple indexings per insert, improving cost efficiency through repeated use of the available cutting corners before disposal.

Application suitability and process security for steel machining

Grade WPP20G is a coated carbide grade optimised for steel applications (ISO P), combining wear resistance with enough toughness to withstand typical variability in steel batches. The grade’s properties support both steady finishing and more demanding roughing passes depending on cutting data and machine capabilities. When integrated into a well-defined process — correct clamping, stable turret setup and appropriate cutting parameters — the insert contributes to process security, consistent part quality and repeatable surface finishes.

FAQ

Which materials is this insert designed for? The SNMM250924-HU7 WPP20G is formulated for machining steels (ISO P); the WPP20G grade and Tiger·tec Gold coating provide the wear resistance and toughness required for standard steel alloys.

How does the Tiger·tec Gold coating benefit the machining process? Tiger·tec Gold on the SNMM250924-HU7 WPP20G improves thermal resistance and reduces flank wear, resulting in longer tool life and more consistent edge retention under steel-cutting conditions.

What is the role of the HU7 chipbreaker? The HU7 chipbreaker on this Walter Tools insert promotes controlled chip formation and evacuation for a range of depths of cut, enhancing process security and reducing the need for manual chip handling.

What are the key geometry details to consider for setup? The insert is a square 90° form with a 2.4 mm corner radius and 25 mm size, with a 0° negative rake; its 9 mm thickness supports rigidity for heavier cuts and interrupted turning.

Can this insert be used for finishing as well as roughing? Yes; with appropriate cutting data the WPP20G grade balances wear resistance and toughness, allowing use in both finishing and more aggressive turning operations on steels.
