CNMM190616-HU3 WPP30G turning insert – Tiger·tec Gold grade for steel machining by Walter Tools

CNMM190616-HU3 WPP30G is a rhombic 80° indexable turning insert designed for robust steel cutting applications in general engineering and production environments

*Tiger·tec Gold coated WPP30G grade *Optimised HU3 chip control *Rhombic 80° geometry for reach *Corner radius 1.6 mm for stable cuts

Greater process stability through optimised coating and grade

The combination of Tiger·tec Gold coating with the WPP30G grade provides a balanced mix of wear resistance and toughness for conventional and demanding steel machining (ISO P). The coating reduces flank wear under thermal load while the carbide substrate maintains edge integrity, which translates into longer tool life and fewer interruptions on the shop floor. The HU3 chipbreaker is configured for controlled fracture and evacuation of chips during medium to heavy cuts, improving cycle-time consistency and reducing the need for manual chip handling. These technical choices support measurable productivity gains and predictable component quality.

Geometry and dimensions engineered for dependable turning

The Rhombic 80° form and the corner radius 1.6 mm deliver a compromise between accessibility and edge strength: the shallow approach angle increases reach for shoulders and noses, while the larger corner radius provides additional support at the cutting edge for interrupted cuts. The insert is produced to tolerance class M, ensuring repeatable seating and stable clamping in standard CNMM toolholders. The relief specification 0° (negative) supports robust engagement at higher feed rates and reduces the risk of edge chipping when machining tougher steel grades. These geometric features reduce rework and help maintain consistent surface finish across series production.

Practical advantages for production and toolroom workflows

As a coated carbide indexable insert, the CNMM190616-HU3 WPP30G allows quick tool changes and straightforward re-indexing, limiting machine downtime and simplifying inventory management. The system is optimised for unalloyed and alloyed steels according to ISO P, with the Walter grade map indicating a prioritised performance range that balances longevity (wear resistance) and toughness for mixed workloads. Integration into a standard turning toolset is seamless owing to the ISO designation, and documentation for cutting parameters can be supplied for feed, speed and depth recommendations to match specific part profiles. This results in cost-efficient machining through extended insert life and improved cycle stability.

FAQ

Which materials is this insert suitable for?
The CNMM190616-HU3 WPP30G turning insert (Walter Tools) is optimised for machining steels classified under ISO P, including unalloyed and alloyed steels.

What characterises the WPP30G grade?
WPP30G is a Walter Tools coated carbide grade in the Tiger·tec Gold family that balances wear resistance and toughness for stable performance during steel turning operations.

How does the HU3 chipbreaker affect machining?
The HU3 chipbreaker on the CNMM190616-HU3 insert promotes controlled chip formation and evacuation when cutting steel, supporting consistent surface finish and easier handling of swarf.

Is the insert compatible with standard CNMM toolholders?
Yes, the ISO designation CNMM190616 indicates compatibility with CNMM-style toolholders and standard clamping systems for indexable turning inserts.

When is a 1.6 mm corner radius recommended?
A 1.6 mm corner radius is recommended when a balance between edge strength and surface finish is required; it is particularly suitable for operations that may encounter intermittent cutting or moderate interruptions.
