TNMG 160412 T515 TNMG – ISO turning insert for Drehen by Tungaloy, CVD-coated carbide, 60°

The TNMG160412 T515 is a triangular ISO turning insert designed for economical external and internal turning of cast iron, offering a robust, double-sided chipbreaker and a 1.2 mm corner radius for repeatable edge life.

• CVD-coated carbide grade T515
• Triangular 16 mm insert geometry
• Double-sided chipbreaker design
• 1.2 mm corner radius for robustness

Reliable material removal for cast iron with predictable tool life

The CVD-coated carbide grade T515 provides a balance between wear resistance and economical cutting performance when machining cast iron. The coating enhances thermal stability and reduces flank wear, which in practice means longer periods between indexings and less machine downtime. For operations with moderate to high cutting speeds, the combination of a coated cemented carbide substrate and a dedicated chipbreaker yields consistent chip control and surface finish, reducing rework and assembly delays.

Stable geometry that supports process security and quick indexability

A 60° triangular cutting shape with a corner radius of 1.2 mm and a 4.76 mm plate thickness delivers mechanical stability in interrupted and continuous cuts. The insert is double-sided, offering two usable cutting edges per side and permitting faster tool changes through simple indexing. The presence of a cylindrical central hole secures positive clamping and ensures positional repeatability in compatible ISO holders; matching of form, clearance angle, tolerance class, fastening and thickness determines holder compatibility.

Practical benefits and selection guidance for workshop use

When selecting the grade and chipbreaker, prioritise workpiece stability and the nature of the cut: the presented chipbreaker suits general cast-iron turning where reliable chip evacuation is essential. A 0° clearance angle supports close control of the tool–workpiece engagement and can help maintain dimensional accuracy under load. For less experienced operators, the insert’s geometry simplifies set-up and helps achieve repeatable part quality with minimal trial runs.

FAQ

What materials is this insert optimised for?
The TNMG160412 T515 insert is optimised for machining cast iron, with a CVD-coated carbide composition that supports thermal stability and wear resistance in these applications.

How does the chipbreaker affect performance?
The double-sided chipbreaker on this insert improves chip control during turning operations, reducing the risk of entanglement and helping to maintain surface quality on interrupted and continuous cuts.

Which holder features are required for correct fitment?
Compatibility requires a matching holder that corresponds to the insert’s form, clearance angle, tolerance class, fastening method, size and thickness; the central cylindrical hole ensures positive clamping when the correct ISO holder is used.

How many usable edges does the insert provide?
As a double-sided triangular insert, the TNMG160412 T515 offers multiple indexable edges, enabling several repositions before replacement and supporting cost-effective tool usage.

Is this grade suitable for interrupted cuts?
Yes, the combination of a robust 1.2 mm corner radius and CVD-coated carbide makes this insert suitable for many interrupted cutting scenarios typical in cast-iron turning.
