TNMA 160420 T5115 – Turning indexable insert, CVD-coated carbide by Tungaloy

The TNMA 160420 T5115 is an ISO‑standard triangular turning insert designed for reliable external and internal turning operations, especially where cast iron machining demands a balance of wear resistance and edge stability

• ISO TNMA 160420 form for secure fit
• CVD-coated carbide grade T5115 for cast iron
• Triangular profile with 60° included angle
• Cylindrical hole; 0° relief; 2 mm corner radius

Efficient machining through optimised cutting material and coating

The insert’s CVD-coated carbide substrate in grade T5115 delivers a combined advantage of wear resistance and maintained cutting-edge integrity when machining cast iron. This material choice reduces flank wear and extends effective tool life under typical turning conditions, which supports higher process uptime and fewer insert changes. For production-driven environments, the result is a measurable reduction in interruptions and a more consistent component quality, achieved without complex setup changes.

Stable cutting geometry that supports robust turning

The ISO TNMA 160420 triangular geometry with a 60° included angle and a 2 mm corner radius provides a robust cutting edge for a variety of turning tasks. The plug‑and‑play fit is defined by form, free angle and thickness, ensuring the insert seats securely in compatible holders. The stated 0° relief contributes to a neutral cutting orientation that is advantageous for stable heavy cuts and for maintaining dimensional repeatability on short to medium overhangs. The triangular shape also enables multiple indexed uses per insert, reducing inventory turnover.

System compatibility and practical application guidance

This insert forms part of a standard turning system comprising an ISO indexable insert, a matching external holder or boring bar, a shim/clone and fastening screw. Compatibility is governed by shape, clearance angle, tolerance class, mounting method, size and thickness, so selecting the matching holder is essential for optimal performance. The grade and chip‑forming configuration are chosen according to workpiece material and machining stability; for cast iron, T5115 is specified as a universal option that balances productivity and edge security.

Operational benefits for production and workshop efficiency

Using a standardised insert such as this one reduces set‑up time and simplifies stocking: ISO interchangeability means fewer unique parts to manage. The CVD coating and alloyed carbide combine to provide stable wear behaviour and predictable tool life, which supports consistent surface finish and repeatable cycle times. Maintenance routines are simplified because inserts can be indexed quickly and clamped with standard screws and shims, limiting machine downtime and allowing focus on process optimisation rather than frequent tooling changes.
