CNMM190612-HU7 WPP30G turning insert — Rhombus 80°, 1.2 mm corner radius (Walter Tools)

CNMM190612-HU7 WPP30G is a Walter Tools turning indexable insert designed for efficient steel machining with a Tiger·tec Gold coated carbide grade

• Tiger·tec Gold coating for long tool life
• HU7 chipbreaker for reliable chip control
• Rhombus 80° geometry for versatile turning applications
• Tolerance class M for consistent dimensional accuracy

Durable coating that raises productivity

The Tiger·tec Gold coating delivers a balanced combination of wear resistance and toughness suited to the thermal and mechanical demands of steel machining. The WPP30G grade, a coated carbide, is optimised for continuous and interrupted cuts where controlled flank wear and edge stability matter. This results in fewer insert changes and more productive machining cycles, which improves overall process efficiency in medium-to-high volume turning operations.

Geometry and chip control for safer cycles

Built with a Rhombus 80° form and a HU7 chipbreaker, the insert promotes stable cutting forces and predictable chip formation when machining steels. The 1.2 mm corner radius increases edge strength for roughing passes while preserving surface quality during finishing passes. The 0° (negative) rake angle supports heavy-duty turning, reducing tool deflection and enabling secure clamping in a wide range of toolholders.

Consistent quality under production conditions

Tolerance class M and the proven construction of this insert help maintain repeatable part dimensions across batches. The thickness code 06 and size designation 19 correspond to standard holder interfaces, simplifying integration into existing tool systems. As a Walter Tools product from the Tiger·tec Gold family, the insert benefits from strict manufacturing control that supports reproducible results and extended service intervals in shop-floor environments.

Clear material suitability and practical benefits

This grade is expressly suitable for steel machining according to the P-group classification, making it a practical option for both unalloyed and alloyed steels. The combination of coating technology and chipbreaker design reduces downtime related to edge failure and poor chip evacuation, which helps to maintain a steady production rhythm. Where process reliability and predictable tool life are priorities, this insert provides a measurable contribution to operational stability.

FAQ

What materials is this insert suitable for?
The CNMM190612-HU7 WPP30G insert is designed primarily for steel machining (ISO group P), including unalloyed and alloyed steels.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating on the WPP30G grade improves wear resistance and edge stability, extending tool life and helping maintain consistent cutting forces during longer cycles.

Which chipbreaker is fitted and what is its advantage?
This insert features the HU7 chipbreaker, which delivers reliable chip control for both continuous and interrupted turning, reducing the risk of entangling chips and supporting safe evacuation.

Is the insert suitable for heavy roughing?
With a 1.2 mm corner radius and a 0° (negative) free angle, the insert provides edge strength and stability suitable for heavier roughing operations when used with an appropriate toolholder.

How does tolerance class M benefit production?
Tolerance class M ensures consistent dimensional accuracy across inserts, which supports repeatable part quality and simplifies tool management in serial production.
