TNMA160420 T5125 triangular ISO turning insert for turning — Tungaloy

A TNMA160420 T5125 indexable turning insert designed for external and internal turning, offering a robust solution for interrupted cuts and less stable machining conditions

• ISO TNMA triangular insert, 16 mm
• CVD-coated carbide grade T5125
• 0° clearance, 60° geometry
• Suitable for interrupted cuts in cast iron

Improve tool life and stability for interrupted cuts

The CVD-coated cemented carbide composition of this insert, paired with the T5125 grade, delivers increased toughness where machining conditions are less stable. This material combination reduces edge chipping during interrupted cuts and maintains a predictable wear pattern, which supports longer tool life and fewer index changes. The hardened coating enhances flank resistance and preserves cutting performance when machining brittle materials such as cast iron, translating into fewer unscheduled tool changes and higher uptime.

ISO conformity for straightforward tool management

Designed to the ISO TNMA designation, this triangular, 16 mm insert simplifies inventory and toolholder matching across standard systems. Compatibility depends on geometry, clearance angle, tolerance class, mounting and thickness; the insert’s ISO form ensures interchangeability with holders specified for TNMA inserts. The standardised dimensions and hole style reduce setup time and make stock management more efficient, while the indexable format allows quick corner changes to extend usable life per insert.

Robust geometry for consistent results and easy clamping

The insert’s corner radius 2 mm and plate thickness 4.76 mm provide structural strength and thermal mass for steadier cutting, while the 0° clearance and 60° included angle deliver predictable engagement and chip flow in many turning setups. The triangular shape offers three usable cutting edges, improving cost efficiency per insert. Supplied with a cylindrical hole, the design supports secure clamping in compatible holders and straightforward replacement during tool changes, helping to maintain consistent surface finish and dimensional control on turned components.

FAQ

What materials can this insert machine reliably?
The Tungaloy TNMA160420 T5125 insert is optimised for machining cast iron and performs well under interrupted-cut conditions due to the tougher T5125 grade and CVD coating.

How is compatibility with toolholders ensured?
Compatibility is determined by the insert form, clearance angle, tolerance class, mounting style, size and thickness; the ISO TNMA designation of this insert supports interchangeability with holders designed for TNMA inserts.

For which turning tasks is this insert best suited?
This indexable insert is suitable for both external and internal turning operations, especially where interrupted cuts or less rigid setups require enhanced edge strength and predictable wear behaviour.

Does the insert include a chipbreaker?
This variant is supplied without a chipbreaker; selection of a suitable chip control solution should be based on material, cutting parameters and the machining strategy.

How does the corner radius affect results?
A 2 mm corner radius increases edge strength and stability, helping to reduce chipping in interrupted cuts while influencing surface finish and allowable feed rates.
