TNMG160408-MP5 WPP20G Turning insert — Tiger·tec Gold, for steel — Walter Tools

A TNMG160408-MP5 WPP20G turning insert engineered for high-productivity steel turning, featuring the Tiger·tec Gold coating and an MP5 chipbreaker for consistent chip formation.

• Tiger·tec Gold coating for long tool life
• MP5 chipbreaker for stable chip formation
• 0.8 mm corner radius for increased edge strength
• Triangle 60° insert with 0° negative rake

Boosted productivity with Tiger·tec Gold and MP5 chip control

The combination of Tiger·tec Gold surface technology and the MP5 chipbreaker is designed to reduce downtime and lower cost per component by extending tool life and stabilising chips during continuous turning of steel (ISO group P). The premium coating reduces flank wear and improves thermal resistance, which means longer intervals between indexings and fewer tool changes. For operations seeking measurable efficiency gains, this geometry supports higher feed rates and reliable material evacuation, translating directly into improved cycle times and predictable output.

Durable edge geometry for consistent process security

A 0.8 mm corner radius together with the triangular 60° form increases resistance to mechanical shock and vibrations, ensuring a robust cutting edge in interrupted or heavy-engagement turns. The 0° negative rake provides a secure cutting attitude that is especially beneficial when machining tougher steel grades or when stable cutting forces are required. These design choices contribute to repeatable dimensional accuracy and consistent surface finish, reducing rework and enhancing machine utilisation.

Practical integration into existing turning systems

The insert follows the TNMG designation and the designation code TNMG160408-MP5 aligns with standard holders and clamping systems, enabling straightforward replacement without extensive tooling changes. The grade WPP20G is optimised for steel machining according to ISO 513 (group P), offering a balance between wear resistance and toughness for general-purpose turning. Cutting data can be adapted from standard steel recommendations; choose speeds conservatively at first and increase feed to exploit the chipformer’s stability. This approach simplifies implementation on production lines and aids process optimisation with minimal trial runs.

Advice and reliable supply for production environments

Walter Tools manufacturing standards and the Tiger·tec Gold family provide process security and consistent tool performance across batches. For application-specific recommendations, adjustments to feeds and speeds, or to confirm compatibility with particular holder systems, expert guidance is available. Technical consultations can help to select the correct insert geometry and grade for a specified steel grade, ensuring that productivity and component quality objectives are met without unnecessary tool wear.

FAQ

What materials is this insert suited for?
The TNMG160408-MP5 WPP20G insert is optimised for steel machining (ISO group P) and designed to handle the typical heat and chip formation encountered when turning unalloyed and alloyed steels.

How does the Tiger·tec Gold coating improve performance?
Tiger·tec Gold on the WPP20G grade increases wear resistance and thermal stability, allowing the insert to maintain cutting edge integrity for longer and thus reducing indexings and tool changes.

When should the MP5 chipbreaker be chosen over other chipformers?
The MP5 chipbreaker is recommended when stable chip control is needed in general-purpose steel turning, particularly where consistent chips and secure evacuation improve cycle reliability.

Can the insert be used in interrupted cuts?
Yes; the 0.8 mm corner radius and negative rake enhance resistance to impact, making this insert suitable for interrupted and heavier-engagement turning operations.

What information is needed to select cutting data for this insert?
Provide the specific steel grade, machine power and rigidity, toolholder type and required surface finish; Walter Tools grade WPP20G and the MP5 chipbreaker will then inform recommended speeds and feeds.
