WNMA080412 T5125 ISO turning insert — triangular indexable insert for turning, Tungaloy

A WNMA080412 T5125 triangular ISO turning insert optimised for interrupted cuts and less stable turning conditions, primarily intended for cast iron machining.

• ISO‑standard triangular form
• CVD‑coated cemented carbide T5125
• Optimised for interrupted cuts in cast iron
• 0° relief angle with 1.2 mm corner radius

Consistent cutting performance under interrupted conditions

The insert offers a CVD‑coated cemented carbide composition that is specifically developed to withstand the shock and variable engagement of interrupted turning. The chosen grade, T5125, provides a tougher substrate that resists chipping where engagement is uneven, helping to reduce unplanned tool changes. The 80° included angle and the 1.2 mm corner radius contribute to stable edge support while the 0° relief angle ensures predictable cutting geometry; together these characteristics promote consistent part finish and reduced scrap rates when facing variable workpiece conditions.

Clear compatibility with ISO toolholders for predictable integration

Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; the insert is delivered as an ISO indexable plate in a trigon shape with a cylindrical hole for clamping. The cutting system is composed of the insert, an appropriate external holder or boring bar, a shim or clamp set and spare screws. This construction enables an uncomplicated exchange and repeatable positioning, so workshop processes are streamlined and machine downtime is minimised by predictable mounting and alignment.

Productivity gains and extended edge life through material engineering

The combination of a tougher substrate and CVD coating balances wear resistance with fracture toughness, which supports longer tool life under cyclic loading typical of interrupted cuts. As a result, machining cycles can be lengthened between indexings, which improves productivity and reduces tooling consumption. The coating stabilises the cutting edge at elevated temperatures and helps maintain a consistent surface finish, making the insert well suited to batch production where repeatability and process stability are essential.

Practical selection and application advice for turning tasks

When selecting an insert, match the chipbreaker and grade to the workpiece material, the machining operation and the machine rigidity; for less stable set‑ups or interrupted cuts, a tougher grade such as T5125 is recommended. The triangular form offers three usable edges per indexable plate, improving economy in series production. Where higher stability is available, adapting holder rigidity and feed rates will further extend service life. If uncertain about the correct chipbreaker or clamping setup, Metav Werkzeuge can provide machining guidance and compatibility checks with existing holders.

FAQ

What materials is this insert suited for?
The Tungaloy WNMA080412 T5125 insert is formulated for machining cast iron and performs well in interrupted cutting conditions thanks to the tougher T5125 grade and its CVD coating.

Can the insert be used for both external and internal turning?
Yes, the ISO trigon insert is suitable for external and internal turning operations when paired with the appropriate external holder or boring bar and correct clamping components.

How does the T5125 grade affect tool life?
The T5125 grade offers increased fracture toughness, which reduces chipping during interrupted cuts and thereby improves effective tool life under variable engagement.

What determines compatibility with an existing holder?
Compatibility is based on form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters ensures correct seating and repeatable performance.

Does the insert include a chipbreaker?
This variant is supplied without a dedicated chipbreaker; select a chipbreaker and grade combination suitable for the workpiece material and machining stability.
