CNMM160612-HU3 WPP30G – Turning insert, Tiger·tec Gold coated, rhombic 80° (Walter Tools)

The CNMM160612-HU3 WPP30G is a rhombic 80° turning insert optimised for the efficient machining of steel, combining a coated carbide grade with a dedicated chipbreaker for consistent performance.

• Tiger·tec Gold coated carbide grade
• Rhombic 80° geometry, 1.2 mm corner radius
• Optimised chipbreaker HU3 for steel machining

Consistent metal removal through optimised cutting geometry

The combination of the rhombic 80° form and a 1.2 mm corner radius ensures stable engagement and reliable edge strength during turning operations. This geometry reduces the likelihood of edge chipping while maintaining good access for turning contours; consequently, machining cycles become more predictable and tool changes are less frequent. The positive layout of the insert promotes controlled cutting forces, which is especially beneficial when producing medium to heavy cuts in structural and alloyed steels.

Coating and grade engineered for process security

A Tiger·tec Gold surface layer on the coated carbide substrate provides improved wear resistance and thermal stability under the typical heat loads of steel machining. The WPP30G grade is formulated for versatile use across ISO P materials, balancing hardness and toughness so that flank wear develops more uniformly. As a result, surface finish and dimensional repeatability are maintained over extended tool life, supporting higher productivity with fewer interruptions.

Chip control and machining efficiency with HU3

The dedicated HU3 chipbreaker is configured to form consistent, short chips when cutting steels, lowering the risk of entanglement and improving evacuation in automated and manual set-ups. Better chip control reduces machine downtime and minimises the need for secondary handling, leading to measurable improvements in process throughput. The insert’s negative relief (0° negative rake) contributes to robust cutting edge support for interrupted cuts and unstable clamping conditions.

Practical benefits for workshop integration

This insert is supplied in the CNMM160612-HU3 format, offering straightforward compatibility with common turning toolholders that accept 16 mm inscribed circle plates. The standard tolerance class M supports interchangeability and repeatable seating, which simplifies tool management in production environments. Given its focus on ISO P materials, the grade is suited to a wide range of steel turning tasks, from batch production to mixed-operation cells, enabling consistent results across workloads.

FAQ

What workpiece materials is this insert suitable for?
The CNMM160612-HU3 WPP30G insert is designed primarily for ISO P materials, so it is suitable for unalloyed and alloyed steel machining.

How does the Tiger·tec Gold coating improve performance?
The Tiger·tec Gold coating on the WPP30G grade enhances wear resistance and thermal stability, which helps the insert maintain cutting edge integrity and consistent surface finish over longer tool life.

Which chip control can be expected with the HU3 breaker?
The HU3 chipbreaker produces short, controlled chips when machining steel, improving evacuation and reducing the risk of chip-related stoppages.

Is the insert compatible with standard CNMM toolholders?
The CNMM160612-HU3 format follows common CNMM dimensions, allowing use with widely available turning toolholders that accept 16 mm inscribed circle inserts.

What benefits does the 1.2 mm corner radius provide in practice?
A 1.2 mm corner radius enhances edge robustness for heavier cuts and intermittent cutting, helping to reduce chipping while still delivering acceptable surface finish on machined parts.
