VNMG160412-MP3 WPP20G indexable turning insert — Tiger·tec Gold, for steel — Walter Tools

VNMG160412-MP3 WPP20G is an indexable turning insert designed for versatile steel machining, offering a coated carbide grade optimised for wear resistance and consistent chip formation

• Tiger·tec Gold coating WPP20G
• MP3 chipbreaker for stable chips
• Rhombus 35° geometry for versatility
• 1.2 mm corner radius for edge strength

Reliable performance and longer operating intervals for steel turning

The combination of the Tiger·tec Gold coating and the WPP20G grade is engineered to improve wear resistance and maintain a stable cutting edge during continuous production runs. With the MP3 chipbreaker, chips are shaped and evacuated consistently, which reduces tool interruptions and contributes to a predictable process. These characteristics translate into measurable gains in uptime and component quality when machining ISO group P materials, meaning unalloyed and alloyed steel grades, especially under medium to heavy cutting conditions.

Robust geometry that supports heavier cuts and complex profiles

The Rhombus 35° form and negative 0° rake angle provide operational robustness and flexibility in application. The oblique geometry allows access to tighter profiles and paired with the 1.2 mm corner radius it increases resistance to edge chipping during interrupted cuts. This geometry benefits workshops that require a balance between roughing capacity and acceptable surface finish without frequent index changes, helping to maintain throughput while protecting the toolholder interface.

Practical setup guidance and efficient process integration

For practical use, the VNMG designation matches conventional toolholder systems; the size and seating ensure repeatable clamping when used with compatible VNMG toolholders. When using the VNMG160412-MP3 WPP20G for roughing, employ conservative feeds with the MP3 chipbreaker to control chip flow; for finishing, moderately increase spindle speed and reduce feed to preserve edge life. The grade and coating are tuned for managing heat and friction in steel turning, so optimised parameters will yield consistent surface quality and predictable tool wear.

FAQ

Which materials is this insert suitable for?
The VNMG160412-MP3 WPP20G is optimised for ISO group P, i.e. machining steel, including both unalloyed and alloyed steels, where the Tiger·tec Gold grade supports typical heat and chip-formation conditions.

What advantages does the Tiger·tec Gold grade provide?
Walter Tools' Tiger·tec Gold grade (WPP20G) offers enhanced wear resistance and edge stability through a coated-carbide technology that reduces friction and improves life in continuous and medium-duty turning.

What is the role of the MP3 chipbreaker?
The MP3 chipbreaker shapes chips for reliable evacuation, supporting steady machining and improving surface quality while reducing the likelihood of chip-related stoppages.

Is the insert suitable for interrupted cuts?
Yes — the 1.2 mm corner radius and the negative rake angle contribute to improved edge strength, making the insert suitable for interrupted cutting with appropriate feed and speed adjustments.

Which toolholders are appropriate for this insert?
The VNMG160412-MP3 WPP20G is intended for standard VNMG-type turning holders that accept Rhombus 35° inserts; verify seat compatibility and clamping system with Metav Werkzeuge or the toolholder manufacturer.
