WNMA 080416 T515 turning indexable insert — Tungaloy

The WNMA080416 T515 is an ISO-standard, trigon-shaped insert intended for external and internal turning of cast iron, optimised for economical, high-productivity machining.

• CVD-coated carbide grade T515
• Trigon form with 80° cutting geometry
• Corner radius 1.6 mm for edge strength

Consistent, economic machining of cast iron

The CVD-coated carbide composition (grade T515) is tailored for the economic machining of cast iron, delivering a balance between wear resistance and cost-effectiveness. The coating increases thermal stability at the cutting edge, which helps maintain geometrical integrity over longer cycles and reduces unplanned tool changes. With a 1.6 mm corner radius, the insert offers a robust cutting edge that tolerates higher feeds without sacrificing surface quality, making it suitable for repetitive production runs where predictable tool life is essential.

Easy integration into ISO tooling systems for secure clamping

Being an ISO-standard turning insert, compatibility with holders is defined by form, relief angle, tolerance class, fixing method, size and thickness. The trigon profile and the specified dimensions allow the insert to be mounted in common external holders or boring bars provided the clamping geometry matches the WNMA form. The presence of a cylindrical hole simplifies alignment and fastening with standard clamping sets and replacement screws, ensuring secure seating and repeatable positioning in multi-shift operations.

Geometry and coating that support stable production

The 80° cutting geometry contributes to favourable cutting forces and a reliable contact area between tool and workpiece, which supports dimensional consistency. The CVD-coated hardmetal substrate resists abrasive wear in cast-iron turning, while the absence of an integrated chipbreaker in this grade allows operators to select a chip control solution tailored to the specific stability of the setup and the nature of the cut. This combination promotes steady performance and reduces process variability across batches.

Practical guidance for selection and mounting

The insert has a 0° relief angle, which depends on toolholder design for optimal cutting action; holders must therefore be chosen to suit this geometry. For interrupted cuts or unstable setups, select a more positive clamping arrangement or a different insert grade to prevent edge chipping. When replacing or specifying inserts, match the ISO designation, the trigon form and corner radius 1.6 mm to the holder and application to ensure predictable results. For assistance with grade selection, clamping sets or mounting torque, internal consultants at Metav Werkzeuge can advise on the most productive configuration.

FAQ

What materials is this insert best suited for? The WNMA080416 T515 insert is designed primarily for machining cast iron, where the CVD-coated carbide provides economical, stable cutting performance.

How does the 1.6 mm corner radius affect machining? A 1.6 mm corner radius increases edge robustness and supports higher feed rates with improved surface finish and longer edge life in repetitive turning operations.

Is this insert compatible with standard ISO toolholders? Yes. The insert follows ISO dimensions, but compatibility depends on holder form, tolerance class, fixing method and thickness; ensure the holder matches the WNMA form and 0° relief specification.

Why choose the T515 grade for production turning? The T515 grade offers a cost-effective balance of wear resistance and thermal stability for cast-iron turning, making it suitable for productive, repeatable machining tasks.

Can the insert be used for interrupted cuts? Interrupted cuts require attention to stability and holder rigidity; the insert can be used if the selected grade and clamping setup accommodate the shock loads typically encountered in interrupted machining.
