TNMU160508R-G57 WPP35G indexable milling insert — Tiger·tec Gold coating, for Stahl

TNMU160508R-G57 WPP35G is an indexable milling insert engineered for productive, repeatable machining of Stahl; suitable for general and slightly tough steel grades where wear resistance and stable chip control are required

• Tiger·tec Gold coated carbide grade WPP35G
• Triangle 60° insert, 0.8 mm corner radius
• Negative 0° rake for stable cutting
• Optimised for Stahl machining (ISO P group)

Higher productivity through advanced coating and grade

The Tiger·tec Gold coating combined with the WPP35G cutting grade delivers a measurable improvement in wear resistance and thermal stability during steel machining. This coated carbide composition is designed to maintain a stable cutting edge under the temperatures typical for ISO P operations, which leads to longer periods between indexings and fewer tool changes. The result is a more continuous production flow and lower tooling-related downtime, making the system particularly suitable for high-mix, medium-volume production environments.

Reliable geometry for consistent surface quality

A triangular 60° shape with a 0.8 mm corner radius and a negative 0° rake angle ensures robust edge support and consistent contact conditions at the tool/workpiece interface. The geometry contributes to predictable chip formation and reduces vibration in heavy engagement passes. The tolerance class M supports reproducible seating in standard indexable holders, so repeatability and surface finish are improved across batches—benefits that matter for repeatable part quality in serial machining.

Clear identification and versatile use in workshops

The ISO designation TNMU160508R-G57 indicates the insert format and chipbreaker type, while the series classification highlights compatibility with a broad range of Stahl materials. The insert thickness 05 and size 16 provide a balance between strength and access in pocketed holders. The integrated G57 chipbreaker is optimised for typical cutting conditions in Stahl, simplifying selection for process planners and reducing the need to trial multiple chipbreakers. This combination supports streamlined inventory management and easier tool standardisation on the shop floor.

FAQ

What materials is this insert designed for?
The TNMU160508R-G57 WPP35G insert and its Tiger·tec Gold coating are optimised for Stahl (ISO group P), covering unalloyed and alloyed steels with typical chip and heat characteristics.

How does the WPP35G grade affect tool life?
WPP35G, as applied in the Tiger·tec Gold series, enhances wear resistance and edge strength, which in turn extends index intervals and reduces frequency of tool changes during Stahl machining.

Can this insert be used for finishing passes?
Yes — the triangular 60° geometry with a 0.8 mm corner radius supports stable cutting for moderate finishing operations while maintaining good edge durability.

What does the TNMU160508R-G57 designation tell me?
The ISO code describes the insert shape, size and chipbreaker; TNMU indicates a triangular indexable format, 1605/16 refers to the sizing, R denotes the positive/negative relief, and G57 identifies the chipbreaker style.

Is the insert compatible with standard milling holders?
The tolerance class M and common triangular pocket dimensions make the insert compatible with most standard indexable milling holders designed for TNMU-type inserts.
