CNMG090308-MP3 WPP20G — Rhombic 80° indexable insert, Tiger·tec Gold, MP3 chipbreaker, Walter Tools

The CNMG090308-MP3 WPP20G is a rhombic 80° turning indexable insert engineered for productive steel machining with the Tiger·tec Gold coated cutting grade.

• Tiger·tec Gold coating for durable edge
• Designed for steel (ISO group P)
• MP3 chipbreaker for reliable chip control
• Rhombic 80° with 0.8 mm corner radius

Increased material removal and surface quality for steel parts

The combination of the Tiger·tec Gold coating and the WPP20G cutting grade delivers a reliable tool life and reproducible results when machining steels. The coated carbide substrate reduces flank wear and improves thermal resistance, which translates into longer intervals between index changes and a steadier surface finish. Thanks to the MP3 chipbreaker, chips are formed consistently, which supports uninterrupted machining cycles and reduces secondary finishing time for turned components.

Stable cutting action and process security through geometry and relief

The rhombic 80° geometry with a 0° negative relief provides a robust cutting edge that resists shock and maintains form under interrupted cuts. The 0.8 mm corner radius contributes to stable edge strength and improved insert life in medium to heavy finishing operations. As a result, the insert supports predictable tool performance, making it suitable for serial production where repeatability and minimal setup adjustments are priorities.

Practical selection and handling for workshop efficiency

This indexable insert is coded for conventional CNMG toolholders and features a compact thickness class for secure clamping. The MP3 chipbreaker is optimised for chip control when turning unalloyed or alloyed steels (ISO group P), reducing risk of entanglement and improving swarf evacuation. For process planning, pairing the insert with an appropriate positive/negative holder and optimised cutting data increases material removal rates while maintaining surface integrity, supporting shorter cycle times and lower overall machining cost.
