WNMM100616-HU3 WPP20G — indexable turning insert, Trigon 80°, Tiger·tec Gold (Walter Tools)

A robust indexable turning insert, the WNMM100616-HU3 WPP20G is designed for high-productivity Stahl turning in industrial machining.

• Tiger·tec Gold coated for longer tool life
• Optimised HU3 chipbreaker for stable chips
• Trigon 80° form for versatile turning

Productivity and wear resistance from advanced coating

The Walter grade WPP20G, based on Tiger·tec Gold coating technology, combines wear resistance with consistent cutting performance when machining Stahl. This coating architecture reduces flank wear and extends resharpening intervals, resulting in fewer tool changes and higher uptime on the shop floor. For production environments where cycle time and reproducibility matter, the insert’s combination of coating and substrate yields a measurable increase in productive cutting time without sacrificing surface quality. The HU3 chipbreaker supports reliable chip formation under typical Stahl cutting conditions, improving process stability.

Geometry tailored for versatile turning operations

The Trigon 80° plate form with a 1.6 mm corner radius and 0° (negative) rake angle provides a balance between strength and form accuracy. The trigon profile offers three effective cutting edges per indexable insert, while the slightly larger corner radius contributes to improved edge strength for interrupted cuts and heavier feed passes. The negative rake improves robustness and reduces cutting-edge chipping when machining tougher batches of Stahl; at the same time, the HU3 chipbreaking geometry helps control chip flow for both semi-finish and roughing tasks. This geometry is ideal where repeatable part accuracy and secure clamping are required.

Practical handling, compatibility and application scope

Supplied in a compact format (size 10, thickness code 06) and manufactured to tolerance class M, the insert fits standard toolholders designed for trigon inserts and suits a broad range of turning tasks in general engineering and production workshops. The grade is specified for the ISO P group, i.e. Stahl, offering a balance of toughness and wear resistance for unalloyed and alloyed steels. The combination of reliable chip control, robust cutting edge and an established coating system helps simplify tool inventory and decision-making in multi-shift operations.

FAQ

What materials is this insert intended for?
The WNMM100616-HU3 WPP20G is specified for the ISO P group and is designed for machining Stahl, combining toughness and wear resistance for a wide range of steel grades.

How does the Tiger·tec Gold grade affect tool life?
The Tiger·tec Gold coating of the WPP20G grade improves wear resistance and thermal stability, which extends service intervals and supports consistent performance during longer production runs.

Which chipbreaker is fitted and what is its benefit?
The HU3 chipbreaker offers controlled chip formation for common turning feeds and depths in Stahl, reducing the risk of entangling chips and improving process reliability.

Is the insert suitable for interrupted cuts or heavier feeds?
Yes; the Trigon 80° geometry with a 1.6 mm corner radius and a negative rake provides increased edge strength, making the insert suitable for interrupted cuts and more demanding feed conditions.

What tolerance and fit can be expected?
The insert is manufactured to tolerance class M and is compatible with holders for trigon indexable inserts, ensuring repeatable seating and secure clamping.
