CNMM190612-HU7 WPP20G — Rhombic Turning Insert for Steel, Walter Tools

The CNMM190612-HU7 WPP20G is a rhombic 80° turning insert, a coated carbide grade designed for productive machining of steel under industrial conditions

• Tiger·tec Gold coating for extended tool life
• Optimised HU7 chipformer for reliable chips
• Rhombic 80° geometry for versatile turning
• 0° negative rake with 1.2 mm corner radius

Longer runtimes with Tiger·tec Gold coating and a coated carbide grade

The combination of Tiger·tec Gold technology and the WPP20G grade provides a coated carbide surface engineered for wear resistance and thermal stability during turning of steels (ISO P). This coating reduces flank wear and helps maintain a sharp cutting edge over extended production runs, which translates into fewer indexings and less downtime. The technology is particularly useful where consistent component quality and process reliability are priorities, since the grade is designed to cope with the typical heat and chip formation encountered when machining a wide range of steel alloys. For customers seeking predictable tool life and repeatable results, this coating-grade pairing offers measurable process advantages.

Robust geometry and chip control for consistent surface finish

The insert’s Rhombic 80° shape combined with a 0° negative rake creates a robust cutting edge that resists chipping in interrupted cuts and heavy engagement. The integrated HU7 chipformer optimises chip separation and evacuation, improving coolant reach and reducing the risk of built-up edge. A corner radius 1.2 mm balances edge strength with achievable surface quality; larger radii increase tool life and support higher feed rates, while the negative rake contributes to a durable cutting edge under tough conditions. The tolerance class M ensures dimensional interchangeability in tool assemblies, supporting predictable set-up and tool change routines on production lines.

Application advantages: productivity, versatility and process security

Designed primarily for machining steel, the insert offers a versatile solution across general engineering and automotive turning tasks where stable chip formation and surface integrity are required. The CNMM190612-HU7 WPP20G indexable insert suits applications from roughing to medium finishing when paired with appropriate depth of cut and feeds; the coated carbide grade helps maintain cutting-edge stability for longer sequences. Because the design focuses on reliable chip control and edge protection, the insert contributes to improved productivity and reduced scrap rates in repetitive production. If there is any uncertainty about specific material grades or cutting parameters, Metav Werkzeuge can supply detailed recommendations and empirical cutting-data sheets to match the operation.

FAQ

Is this insert suitable for stainless steel?
This turning insert is formulated for steel (ISO P); stainless steel suitability is not specified for the WPP20G grade and alternative grades should be considered for austenitic stainless steels

What does the HU7 chipformer deliver?
The HU7 chipformer on this insert promotes predictable chip segmentation and evacuation, reducing the risk of long chips and supporting consistent surface quality during steel turning

How does the 0° negative rake affect performance?
A 0° negative rake provides a tougher cutting edge, beneficial for interrupted cuts and heavy engagement; it increases edge strength while slightly raising cutting forces compared with positive rake options

Can the insert be used for finishing operations?
With the corner radius 1.2 mm and the coated grade, the insert can be used for medium finishing where a balance of surface quality and tool life is required; final finish expectations depend on machine rigidity and cutting parameters

What exactly is Tiger·tec Gold?
Tiger·tec Gold is Walter’s multilayer coating technology applied to the WPP20G grade, engineered to enhance wear resistance and thermal stability during machining of steels
