SNMM150616-HU3 WPP20G indexable turning insert, square 90°, Tiger·tec Gold – Walter Tools

The SNMM150616-HU3 WPP20G is a coated carbide turning insert designed for stable, high-productivity steel machining in general turning applications.

Tiger·tec Gold coating for extended tool life
Optimised HU3 chipbreaker for stable chip control
Square 90° form with 1.6 mm corner radius
Negative 0° relief for robust turning operations

Consistent performance for steel turning with fewer interruptions

The insert combines the WPP20G grade of the Tiger·tec Gold series with a dedicated HU3 chipbreaker, producing predictable chip shapes when machining a wide range of steel grades. The substrate and coating pairing—coated carbide—is selected to manage the typical heat and abrasion encountered in steel turning. For production environments this translates into longer intervals between tool changes and fewer interrupted cycles, improving overall equipment efficiency without sacrificing surface quality.

Stable chip control and improved process reliability

The HU3 chipbreaker is engineered to promote short, controllable chips under conventional feeds, reducing the risk of entanglement and aiding swarf evacuation. Combined with the square 90° geometry, the insert supports secure radial engagement and consistent cutting forces. This stability benefits cycle times and reduces the likelihood of tool-induced part scrap, giving a measurable contribution to process reliability on the shop floor.

Robust edge design for predictable wear and longer life

A 1.6 mm corner radius and 0° (negative) relief create a tougher cutting edge that resists chipping when taking heavier cuts or encountering interrupted surfaces. The WPP20G grade is a coated hardmetal formulation optimised for steel, balancing wear resistance and toughness. The result is repeatable tool life and a dependable surface finish on turned components, with fewer emergency tool changes during multi-shift production.

Practical application and holder compatibility for efficient integration

The SNMM150616-HU3 geometry follows common insert standards for ease of integration into existing toolholders and turning systems. The insert’s format suits general-purpose turning holders designed for square 90° inserts, allowing straightforward replacement and setup. In mixed-production shops this compatibility reduces changeover time and simplifies inventory management while maintaining high machining performance.

FAQ

Which materials is this insert designed for?
The WPP20G grade in the SNMM150616-HU3 insert is formulated for steel (ISO group P) and is optimised to handle the typical heat and chip formation of alloyed and unalloyed steels.

How does the HU3 chipbreaker affect machining?
The HU3 chipbreaker promotes short, stable chips at conventional feeds, improving chip evacuation and reducing swarf-related interruptions during turning.

What benefit does the 1.6 mm corner radius provide?
A 1.6 mm corner radius strengthens the cutting edge, permitting more robust cutting conditions and improved resistance to edge chipping for longer, predictable tool life.

Is the insert compatible with standard toolholders for square inserts?
Yes. The square 90° format follows common insert standards, allowing use with holders designed for SNMM-style square inserts without special adaptations.

What does the negative 0° relief mean in practice?
A 0° (negative) relief produces a stable, strong insert seat and edge, suitable for turning tasks where tool rigidity and edge protection are priorities.
