WNMA 080408 T5115 – ISO trigon turning insert with 0.8 mm radius by Tungaloy

The WNMA080408 T5115 is an ISO‑standard trigon insert designed for external and internal turning, offering a balanced combination of wear resistance and edge stability for cast iron machining.

• CVD-coated carbide grade T5115
• ISO-standard trigon insert 080408
• 0.8 mm corner radius for smoother profiles
• Cylindrical hole for secure locating

High productivity through CVD‑coated carbide technology

The CVD‑coated carbide grade T5115 provides a reliable compromise between wear resistance and edge strength, making it suitable for continuous production runs. The coating reduces flank wear under abrasive conditions typical of cast iron, while the substrate maintains a durable cutting edge; this balance supports longer tool life and fewer index‑changes, which directly improves process uptime and cost efficiency.

Geometry engineered for repeatable results and robust edges

With an included angle of 80° and a corner radius of 0.8 mm, the geometry of this trigon insert delivers stable cutting forces and predictable profile transitions. The trigon shape and the cylindrical centre hole ensure positive seating and reproducible clamping, which reduces setup variation. These characteristics make the insert well suited to operations where dimensional repeatability and surface quality are priorities.

Streamlined integration into ISO insert systems

The insert is an ISO‑norm component whose compatibility with a holder depends on form, relief angle, tolerance class, retention method, size and thickness. This standardisation simplifies tool planning: the same insert designation can be matched to a range of external holders, boring bars or adapter systems. For turning tasks, select the appropriate chipbreaker and grade according to workpiece material and machining stability; the T5115 grade is optimised for cast iron applications without a built‑in chipbreaker.

Practical machining advice for reliable results

When fitting the insert, ensure the seat is clean and that the clamping torque conforms to the holder manufacturer’s specification to avoid movement during cutting. The absence of an integrated chipbreaker makes this insert particularly useful for general turning and finishing passes where a smooth chip flow is acceptable; consider using a dedicated chip control geometry if heavy interrupted cuts are encountered. For holder selection, choose a toolholder that matches the insert form and clearance requirements to get the full benefit of the ISO‑standard system and Tungaloy material science.

FAQ

What materials is this insert suitable for?
The WNMA080408 T5115 insert is a Tungaloy CVD‑coated carbide grade intended primarily for cast iron machining and general turning applications.

How is the insert secured in a holder?
The insert uses a cylindrical centre hole and is secured according to ISO holder specifications; compatibility depends on holder form, relief angle and tolerance class.

Does this insert include a chipbreaker?
This designation is supplied without an integrated chipbreaker; it is therefore suited to finishing and general turning where chip control is acceptable without a breaker.

What are the key geometry dimensions to consider for setup?
Important dimensions are the 80° included angle and the 0.8 mm corner radius; ensure the chosen holder matches these values for correct seating and cutting performance.

Can this insert be used for internal turning as well as external?
Yes, the insert is designed for both external and internal turning operations when paired with an appropriate holder or boring bar.
