TNMG270616-RP5 WPP20G — Turning indexable insert, triangular 60°, Tiger·tec Gold (Walter Tools)

A TNMG270616-RP5 WPP20G turning insert engineered for efficient steel turning, offering universal performance and consistent chip control for production and job-shop environments

• Tiger·tec Gold coated carbide grade WPP20G
• Optimised RP5 chipbreaker for steel turning
• Triangular 60° shape with 1.6 mm corner radius
• 0° negative rake for secure roughing cuts

Longer tool life through a universal, wear-resistant grade

The WPP20G grade, part of the Tiger·tec Gold series, is a coated carbide solution optimised for the thermal and mechanical conditions of steel turning. Its balanced substrate and coating combination provides a durable cutting edge, which reduces the frequency of insert changes and lowers tool inventory requirements. In practice, this means fewer interruptions to production and a more economical machining process when turning a wide range of steels. The grade is designed to manage typical chip formation and temperature loads encountered in steel (P) machining.

Stable cutting and reproducible surface quality

The RP5 chipbreaker is engineered to produce controllable chip shapes at common turning feeds, which improves chip evacuation and reduces the risk of re-cutting. The insert’s negative 0° rake contributes to a robust cutting edge that resists chipping during interrupted cuts or heavy roughing passes, delivering stable process behaviour and more consistent surface finish. For operators unfamiliar with chipbreaker design, RP5 aims to strike a balance between short, manageable chips and a smooth transition to finishing passes.

Geometry that boosts process reliability and repeatability

The TNMG triangular form with a 60° included angle and a 1.6 mm corner radius increases edge strength while still permitting fine finishing when required. This geometry supports secure clamping in standard TNMG toolholders and helps dampen vibration, leading to repeatable dimensional results and predictable tool life. The combination of plate thickness and corner radius is particularly suited to mixed-operational environments where occasional heavy cuts and subsequent finishing passes are necessary.

Compatibility, handling and workshop benefits

Marked with the ISO designation TNMG270616-RP5 WPP20G, this insert fits holders that accept the TNMG family and is intended primarily for steel (P) applications. The coated surface simplifies entry into a wide variety of steels and reduces the need for multiple specialised grades. Technical staff will value the straightforward identification of chipbreaker and grade for quicker tool selection and inventory control. For specific clamping or holder compatibility questions, Metav Werkzeuge can provide fixture checks and practical recommendations.

FAQ

What materials is this insert suitable for?
The TNMG270616-RP5 WPP20G insert is intended primarily for steel (P) machining; the WPP20G grade is formulated for a broad range of steels typical in industrial turning.

What performance advantage does the WPP20G grade provide?
WPP20G, part of the Tiger·tec Gold family, gives a balanced wear resistance and versatility for turning operations, helping to extend tool life and reduce tool change frequency on steel components.

How does the RP5 chipbreaker influence machining?
The RP5 chipbreaker promotes controlled chip formation and reliable evacuation during turning, which improves process security and contributes to a consistent surface finish with the TNMG geometry.

Which toolholders accept this insert?
The insert follows the TNMG family geometry and is compatible with standard TNMG toolholders that accommodate triangular 60° indexable inserts; verification of clamping compatibility is advised before first use.

How is the corner radius relevant to my application?
The 1.6 mm corner radius increases edge robustness for heavier cuts while still permitting acceptable finishing; it balances strength and surface quality for mixed roughing and finishing tasks.
