DNMG150408-MP3 WPP20G indexable turning insert — Tiger·tec Gold, for steel machining (Rhombic 55°)

The DNMG150408-MP3 WPP20G is an indexable turning insert designed for steel applications; it pairs a coated carbide grade from the Tiger·tec Gold family with an MP3 chipbreaker and a rhombic 55° form to ensure dependable chip control and edge stability in general turning operations.

• Tiger·tec Gold coated carbide grade WPP20G
• Optimised MP3 chipbreaker for stable chips
• Rhombic 55° shape with 0.8 mm corner radius
• Negative 0° rake for robust turning

High productivity for steel turning through an advanced coating philosophy

The combination of Tiger·tec Gold coating and the WPP20G grade gives this insert a high process reliability in steel machining (ISO P). The coating technology reduces wear and supports a stable cutting edge over extended tool life, which in turn lowers downtime and improves overall productivity. For practical purposes, the coated carbide substrate is designed to handle the temperatures and chip formation typical for unalloyed and alloyed steels; this means fewer seat changes and a steadier production flow.

Consistent chip control and improved surface quality thanks to the MP3 chipbreaker

The MP3 chipbreaker is optimised for stable, controllable chip formation when turning steels. By guiding chips reliably away from the cutting zone, the insert reduces the risk of re-cutting and surface defects, contributing to a more consistent component finish. The rhombic 55° geometry helps to balance cutting forces and accessibility in medium- to general-purpose turning, while the 0.8 mm corner radius supports edge robustness in both finishing and light roughing passes.

Robust geometry and dimensional stability for repeatable results

With a negative 0° rake and an M tolerance class, the insert offers a conservative, sturdy cutting geometry that favours repeatable performance under varied cutting conditions. The plate thickness and stable edge preparation contribute to vibration resistance and predictable wear progression. These attributes make the insert suitable for job shops and production environments where repeatability and tool life predictability are priorities.

Practical application advice to maximise tool life and process security

For best results, match the insert to a toolholder that supports the rhombic 55° form and ensures minimal overhang to maintain rigidity. The insert is intended for steel machining as classified under ISO P; selecting cutting parameters that suit the WPP20G grade and the MP3 chipbreaker will yield balanced wear and good surface finish. If further parameter tuning is needed, Metav Werkzeuge provides technical advice and can assist with grade or geometry selection for specific steel grades.
