CPMT 090308 T5115 Tungaloy indexable insert for turning

The CPMT090308 T5115 is an ISO‑standard rhombic indexable insert engineered for external and internal turning, optimised for cast‑iron applications.

• CVD-coated carbide grade T5115
• ISO rhombic insert, size 09
• Optimised for cast-iron turning
• 11° clearance angle and 0.8 mm radius

Reliable wear resistance for productive turning

The combination of CVD‑coated surface treatment and a high‑performance carbide substrate in grade T5115 delivers extended tool life and consistent cutting performance when machining cast‑iron. The coating reduces abrasive wear while the substrate maintains edge stability, so fewer insert changes are required during longer production runs. This translates into lower downtime and a more predictable cost per finished component, particularly in medium to high‑volume turning operations where repeatability matters.

ISO geometry for fast, repeatable setup

Designed to the ISO series of turning inserts, the rhombic form and size 09 ensure straightforward interchangeability with compatible toolholders. Key geometry values such as 3.18 mm plate thickness, an 11° clearance angle and a 0.8 mm corner radius are specified for reliable seating and consistent cutting engagement. The insert features a cylindrical hole with a single‑sided countersink (40°–60°), enabling secure fastening and repeatable clamping—factors that minimise setup time and reduce variability between tool changes.

Controlled chip formation and improved surface quality

This grade is supplied with a one‑sided chipbreaker tuned for cast‑iron applications to promote stable chip formation and reduce the risk of built‑up edge. Stable chips help maintain surface integrity and reduce manual chip handling, improving both workplace safety and finished part appearance. For less experienced users, the chipbreaker reduces sensitivity to small deviations in feed or rigidity, producing a reliable surface finish with fewer corrective passes.

Practical application scope and selection guidance

Suitable for both external and internal turning, this insert performs best where cast‑iron removal and consistent surface quality are priorities. The insert is supplied as part of a system comprising the ISO‑rated insert, a matching external holder or boring bar, and the appropriate underlay/clamp set with replacement screws. Selection should match the chipbreaker and grade to the workpiece, machining method and machine rigidity to achieve the best balance between tool life and productivity. Metav Werkzeuge’s technical team can advise on holder compatibility and the correct tolerance class for specific setups.
