TPMN 160308 T5115 Turning insert (ISO triangular) – Tungaloy

TPMN 160308 T5115 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for cast iron machining and compatible with standard holders

• ISO triangular insert, 60° geometry
• CVD-coated carbide grade T5115
• Optimised for cast iron machining
• Corner radius 0.8 mm, 3.18 mm thick

Longer tool life through engineered coating and grade

The CVD-coated carbide designation refers to a chemical vapour deposition layer applied to a cemented carbide substrate, which enhances wear resistance and edge toughness. This balance between hardness and toughness in the T5115 grade reduces flank and crater wear during interrupted cuts and high abrasion encountered when machining cast iron, resulting in more consistent tool life and fewer index changes. For production environments this translates into lower tool consumption and improved process reliability.

Consistent surface quality from optimised geometry

The insert’s triangular geometry and 60° cutting angle, combined with a corner radius of 0.8 mm and a plate thickness of 3.18 mm, deliver predictable cutting forces and chip behaviour. A defined relief angle of 11° supports secure seating in the toolholder and stable cutting under varying depths of cut. These geometric parameters help achieve repeatable surface finishes and dimensional stability on turned components, especially on external profiles and bore-facing operations.

Easy integration into ISO-based turning systems

As part of an ISO turning insert series, compatibility with holders depends on form, relief angle, tolerance class, clamp method, size and thickness. The insert is provided without a hole and without an integrated chipbreaker, making it suitable for holders that locate and clamp inserts by flank and edge. The standardised dimensions ensure straightforward replacement in existing tool systems, minimising setup time and inventory complexity while ensuring process continuity.

Practical application advice for cast iron turning

This universal T5115 grade is developed for cast iron where a compromise between abrasion resistance and edge robustness is required. When selecting a chipbreaker and adapting cutting parameters, match the insert grade and edge preparation to workpiece stability and machining strategy: choose sturdier edge forms for interrupted cuts and finer radii for finishing passes. Correct insert choice enables improved productivity and predictable tool changes, supporting efficient cycle planning in series production.

FAQ

What materials is this insert suitable for? This insert, the TPMN 160308 T5115 from Tungaloy, is optimised for machining cast iron and provides a balance of wear resistance and edge stability for that material class.

Is the insert compatible with standard ISO holders? Yes, the ISO designation 160308 indicates standard dimensions; compatibility depends on holder form, relief angle, tolerance class, clamp method, size and thickness.

Does the insert include a chipbreaker? The supplied variant is specified without a chipbreaker; chip control is determined by the holder and the selected chipbreaker geometry where applicable.

How does the T5115 grade differ from more wear-resistant grades? T5115 offers a compromise between abrasion resistance and edge toughness for cast iron; harder, more wear-focused grades will extend life in highly abrasive conditions but may reduce edge robustness.

What is the exact corner radius and thickness of the plate? The plate features a 0.8 mm corner radius and a plate thickness of 3.18 mm, suitable for a range of finishing and medium-turning operations.
