SNMM120408-HU3 WPP30G — indexable turning insert, HU3 chipbreaker, for steel (Tiger·tec Gold) — Walter Tools

The SNMM120408-HU3 WPP30G is an indexable turning insert designed for reliable steel machining, offering a Tiger·tec Gold coated grade and HU3 chip control in a square 90° format.

• Tiger·tec Gold coating for enhanced wear resistance
• HU3 chipbreaker for controlled chip formation
• Square 90° insert, 12 mm format
• 0.8 mm corner radius for robust cutting edges

High-performance turning where economy matters

The SNMM120408-HU3 WPP30G insert combines a Tiger·tec Gold coated cemented carbide grade with a purpose-designed HU3 chipbreaker to deliver stable cutting in a wide range of steels. The coded grade WPP30G is tuned for the heat and chip characteristics of steels (ISO group P), offering a balance of wear resistance and toughness that helps to extend tool life and reduce tooling cost per part. The square 90° geometry and 12 mm size enable predictable engagement and straightforward programming for standard turning operations.

Secure edges and predictable chip behaviour

A 0.8 mm corner radius and the HU3 chip control geometry create reliable edge strength and consistent swarf formation, which reduces the risk of edge chipping and machine stoppages. For manufacturers aiming to increase process uptime, the combination of a robust edge and controlled chips means fewer interruptions for tool changes and improved surface finishes without escalating cutting forces. The applied coating technology also improves thermal resilience, maintaining cutting performance under extended runs.

Practical application guidance for production use

This indexable insert is optimised for general steel turning; the grade is intended for unalloyed and alloyed steels where typical heat generation and chip forms occur. In practice, select cutting parameters that match your machine capability and the grade’s moderate hardness: moderate speeds with appropriate feed and depth settings will exploit the Tiger·tec Gold advantages while maintaining tool life. If additional data or parameter tuning is required, Metav Werkzeuge can provide tailored cutting recommendations and application notes.

Reliability and brand assurance for series production

Walter Tools offers proven geometry and material science in its insert series, supporting consistent, repeatable results in manufacturing environments. The coated carbide grade and precision tolerancing support process stability and help achieve consistent part quality. For shops that value dependable tool performance in serial production, this insert presents a pragmatic choice that balances wear resistance, edge security and versatility across standard steel turning tasks.

FAQ

What materials is this insert suitable for?
The SNMM120408-HU3 WPP30G insert is specified for steel machining (ISO group P); the WPP30G grade is formulated for the chip and heat behaviour typical of unalloyed and alloyed steels.

How does the HU3 chipbreaker affect machining?
The HU3 chipbreaker on this Walter Tools insert promotes controlled chip formation and evacuation, reducing the chance of long stringy chips and improving process reliability during turning operations.

Is the corner radius suitable for roughing or finishing?
The 0.8 mm corner radius offers a compromise between edge strength for roughing and the ability to achieve good surface finishes; it is well suited to semi-finishing applications in steel.

Can this insert be used in automatic tool changers and indexable systems?
Yes, the SNMM120408-HU3 WPP30G is an indexable insert designed for standard toolholders compatible with square 90° inserts; confirm holder compatibility and clamping specifications before assembly.

What distinguishes the WPP30G Tiger·tec Gold grade?
WPP30G belongs to Walter Tools’ Tiger·tec Gold coating technology; it combines a coated cemented carbide substrate with tailored surface properties to balance wear resistance and toughness for steel cutting.
