TNMA160404 T5115 indexable turning insert — triangular 60° design by Tungaloy

TNMA160404 T5115 is an ISO-compliant indexable turning insert for general turning applications, optimised for cast-iron machining with a balanced mix of wear resistance and edge stability.

• ISO‑compliant TNMA triangular insert
• CVD‑coated carbide grade T5115
• Universal suitability for cast iron
• 0.4 mm corner radius, 60° cutting angle

Engineered for stable, repeatable turning performance

The CVD‑coated carbide composition and the T5115 grade deliver a dependable balance between abrasion resistance and edge strength, which is particularly valuable in interrupted cuts and mixed-production runs. As an ISO indexable turning insert in a triangular format, the component provides three usable cutting edges per insert and a consistent reference for repeatable set-up. The 60° geometry and a 0.4 mm corner radius reduce cutting forces while maintaining acceptable strength for external and internal turning, contributing to predictable tool life and fewer tool changes.

Geometry and grade choice that simplify process decisions

Choosing the correct insert geometry is crucial for machining efficiency. The triangular shape and the specified 60° cutting angle offer good versatility across finishing and semi‑finishing operations, while the 4.76 mm thickness ensures rigidity in standard holders. The zero-degree rake (0°) provides a neutral shear condition suited to many grey and ductile cast-iron grades; the absence of a chipbreaker in this variant reduces clogging risk when paired with appropriate cutting parameters. These attributes translate into fewer interruptions and a more efficient machining cycle.

Practical benefits at the machine and shop floor level

Using this indexable plate reduces set-up time and streamlines inventory management through ISO compatibility and a familiar insert form. The carbide substrate with CVD coating stands up to the abrasive nature of cast iron, delivering longer edge life and more consistent surface finish between tool changes. The central cylindrical hole secures the insert reliably in standard clamping systems, improving repeatability and helping to maintain tolerance control on turned parts. For mixed-series production, the universal nature of the grade supports flexible scheduling without frequent tool swaps.

FAQ

What materials is this insert best suited for? The TNMA160404 T5115 insert is formulated as a universal grade for cast iron machining, offering a balanced combination of wear resistance and edge stability for grey and nodular irons.

How does the 0.4 mm corner radius affect cutting performance? A 0.4 mm corner radius provides a compromise between strength and finish: it lowers cutting stress compared with a larger radius while improving edge life over a sharp corner in typical turning operations.

Is this insert compatible with standard ISO triangular holders? Yes, the insert follows ISO geometry for triangular indexable inserts; compatibility depends on holder form, size, clamping method and thickness — the central cylindrical hole supports secure clamping in standard systems.

Does the insert include a chipbreaker? This variant is supplied without a chipbreaker, so cutting parameters and coolant strategy should be selected to ensure reliable chip evacuation during the intended turning operation.
