CNMM250924-HU3 WPP20G — Indexable turning insert with Tiger·tec Gold coating (Walter Tools)

The CNMM250924-HU3 WPP20G is an indexable turning insert designed for general steel turning, offering a rhombic 80° geometry and a dedicated chipbreaker for stable chip control in medium to demanding operations

• Tiger·tec Gold coating for higher productivity
• WPP20G grade optimised for steel machining
• Rhombus 80° geometry with 2.4 mm corner radius
• 0° (negative) relief for secure edge support

Boost in-process efficiency with advanced coating

The Tiger·tec Gold coating, applied to a coated carbide substrate, reduces flank wear and extends tool life in continuous turning cycles. This technology is engineered to resist typical heat and abrasion encountered when machining steel, so production runs benefit from fewer insert changes and more predictable tool costs. The coating chemistry and microstructure are optimised for sustained cutting performance, which supports higher metal removal rates and consistent surface finish.

Reliable chip control and cutting stability

Equipped with the chipbreaker HU3, the insert delivers controlled chip formation for a wide range of cutting conditions common in steel machining. The combination of the Rhombus 80° shape and a 2.4 mm corner radius improves edge strength and reduces the likelihood of chipping under interrupted cuts. Stable chip flow and secure edge support translate into fewer process interruptions and improved part quality during turned components production.

Geometry and grade matched to steel applications

The WPP20G grade is specified for steel workpieces and balances wear resistance and toughness for universal performance across unalloyed and alloyed steels. The 0° (negative) relief angle provides robust support behind the cutting edge, making the insert suitable for harder engagement angles or heavier feed applications where edge security is essential. Tolerance class M ensures consistent seating and repeatability when replacing inserts in indexable toolholders.

Practical procurement and application support

The insert’s standard 25 mm size and recognised ISO-style designation simplify inventory management and toolholder compatibility checks. Technical teams can use the clear designation to match cutting parameters and toolholders quickly, while Metav Werkzeuge can supply recommended cutting data for specific steel grades and machining strategies. For process planners seeking to reduce set-up time, the standardised format and repeatable performance of this insert help shorten qualification cycles.

FAQ

What materials is this insert intended for?
The CNMM250924-HU3 WPP20G insert is formulated for machining steel (ISO group P), with the WPP20G grade optimised for a balance of wear resistance and toughness.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on this Walter Tools insert improves resistance to flank wear and abrasion, enabling longer tool life and more consistent machining performance in steel turning operations.

Which chipbreaker is fitted and what is its effect?
This insert features the HU3 chipbreaker, designed to produce short, controllable chips and support stable cutting over a range of feeds and depths typical in steel turning.

Is the geometry suitable for interrupted cuts?
The Rhombus 80° form combined with a 2.4 mm corner radius and 0° (negative) relief offers strong edge support, making the insert appropriate for many interrupted and heavy-engagement turning tasks.

How does tolerance class M influence tool setup?
Tolerance class M ensures consistent dimensions and repeatability when seating the insert in precision toolholders, reducing variability during index changes.
