TNMG 160412 T515 Turning insert (ISO TNMG160412) by Tungaloy

The TNMG 160412 T515 is an ISO-standard triangular indexable insert designed for external and internal turning of cast iron, offering a CVD-coated carbide grade optimised for economical, high-productivity cuts.

• CVD-coated carbide for economical cast-iron machining
• ISO TNMG160412 triangular insert, 60° geometry
• Double-sided chipbreaker for stable chip control
• 1.2 mm corner radius with cylindrical hole mounting

Consistent, economical machining for cast iron components

The CVD-coated carbide grade T515 is formulated to balance tool life and cost-efficiency when machining cast iron, making it suitable where stable cutting and predictable performance are required. The coating reduces adhesive wear and improves thermal resistance, so the insert sustains higher cutting speeds without premature degradation. The net effect is fewer index changes, less downtime and a noticeable reduction in per-part tooling cost while maintaining the required surface quality.

Straightforward fitment and reliable clamping for quick tool changes

Designed to the ISO TNMG160412 specification, this triangular insert features a 60° geometry, a cylindrical hole and a nominal thickness of 4.76 mm, ensuring compatibility with a wide range of standard external holders and boring bars. Because compatibility depends on form, clearance angle, tolerance class, fastening and size, the ISO conformity simplifies inventory management and reduces setup errors. The double-sided design doubles available cutting edges per insert, which improves economy and reduces handling time.

Geometry and chip control deliver predictable results and surface finish

With a 1.2 mm corner radius and a double-sided chipbreaker, the cutting edge offers a compromise between strength and finishing capability: the radius stabilises the cutting edge under intermittent cuts, while the chipbreaker manages swarf formation for safer chip evacuation. For workshops less familiar with technical terms, a chipbreaker is a groove or form on the rake face that forces chips to curl and break, preventing long, hazardous swarf and improving surface consistency. The result is a dependable, repeatable process suited to batch production and single-piece machining alike.

FAQ

What materials is this insert suited for?
The insert is specified for economical machining of cast iron; the T515 CVD-coated grade in the TNMG160412 form is optimised for that application.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the insert controls chip shape and length, improving evacuation and reducing surface defects during turning operations.

Is the insert compatible with standard ISO TNMG holders?
Yes, the insert conforms to ISO TNMG160412 dimensions and mounts via a cylindrical hole; compatibility is determined by holder form, clearance angle and tolerance class.

How many cutting edges are available per insert?
The insert is double-sided, providing multiple indexable cutting edges to extend effective tool life and reduce replacement frequency.

What are the key geometry values to consider during setup?
Relevant values are the 60° main geometry, 1.2 mm corner radius and 0° clearance angle; these affect cutting forces, finish and tool strength.
