TNMA160412 T515 TNMA turning insert (ISO 160412) – CVD-coated carbide, 1.2 mm radius — Tungaloy

A TNMA160412 T515 indexable turning insert designed for ISO-standard external and internal turning, optimised for cast-iron machining.

• ISO triangular insert TNMA 60° geometry
• CVD-coated carbide grade T515 for cast iron
• 1.2 mm corner radius for stable cutting
• 4.76 mm thickness, cylindrical hole fastening

Higher throughput for cast-iron turning with economic tool life

The CVD-coated carbide grade T515 is formulated for productive machining of cast iron, combining wear resistance with stable chip formation to extend effective tool life. This results in reduced tool change frequency and lower process costs while maintaining surface quality. The neutral topography (no chipbreaker) allows pairing with the appropriate chipformer in the holder, enabling flexibility across roughing and finishing tasks and supporting consistent cycle times in series production.

Consistent clamping and repeatable geometry for reliable results

The insert follows ISO norms for indexable turning plates, ensuring compatibility with standard holders and boring bars. The triangular shape and cylindrical hole fastening, together with the 60° included angle and 0° clearance geometry, deliver repeatable seating and quick, secure clamping. The 1.2 mm corner radius reduces edge chipping risk under moderate loads, while the 4.76 mm thickness contributes to rigidity and vibration damping, improving dimensional stability on long bores or overhung setups.

Practical guidance for efficient use in external and internal turning

Suitable for external and internal turning, the insert functions well where stable cutting forces and good surface consistency are required. As an indexable insert without an integral chipbreaker, selection of the correct holder and chip control accessory is crucial: choose a toolholder and shim configuration that match component rigidity and interruption pattern. For interrupted cuts or unstable setups, a holder with positive support and a matching chipformer will preserve edge life and help avoid built-up edge.

System approach for quick replacement and production continuity

The ISO plate forms part of a complete system comprising the insert, compatible holder, shim and clamping set plus replacement screws. This modular approach simplifies inventory management and minimises machine downtime during tool changes. Identification for ordering is straightforward via SKU TUN6747818; matching the insert to the correct holder geometry and tolerance class ensures optimal seating and performance across repeated indexings.
