TNMG 160408 T5115 Turning insert by Tungaloy — ISO triangular indexable insert, CVD-coated carbide, 0.8 mm radius

The TNMG160408 T5115 is an ISO triangular indexable turning insert designed for external and internal turning, offering a universal solution optimised for cast-iron applications.

• TNMG form, ISO 160408 specification
• CVD-coated carbide in T5115 universal grade
• 0.8 mm corner radius with cylindrical hole

Reliable edge life for cast-iron turning

The combination of a CVD-coated carbide substrate and the T5115 cutting grade provides a balanced mix of wear resistance and edge stability, especially for machining cast iron. This geometry and coating reduce flank wear under interrupted cuts and variable workpiece conditions, which leads to longer intervals between indexations and fewer tool changes. The neutral relief geometry helps preserve the cutting edge during tough engagement, while the universal grade minimises the need for multiple specialised inserts.

Secure clamping and straightforward system integration

Produced to ISO specifications, the insert ensures predictable compatibility with holders when form, relief angle, tolerance class, fastening method, size and thickness are matched. The ISO 160408 designation indicates a triangular form with a 60° included angle; the insert features a cylindrical hole for positive clamping and a standard thickness of 4.76 mm, enabling stable fixation in suitable external holders or boring bars. Typical system assembly comprises an indexable insert, a matched outer holder or boring bar, a shim/clamping set and replacement screws for safe, repeatable mounting.

Productive machining through geometry and chip control

A 0.8 mm corner radius provides a robust cutting edge that improves surface finish and reduces edge chipping during interrupted cuts, while the double-sided chipbreaker design allows economical use of both sides of the insert before replacement. The triangular form and 60° included angle deliver flexibility for a range of turning operations, and the moderate thickness increases rigidity for higher cutting forces. Together these features support steady material removal rates and contribute to consistent cycle times and lower per-part tooling costs.

FAQ

What materials is this insert best suited for? The Tungaloy TNMG160408 T5115 insert is a universal grade optimised for cast iron, offering balanced wear resistance and edge stability for typical grey and nodular cast-iron turning.

Is the insert indexable and reversible? Yes. The triangular geometry with a double-sided chipbreaker allows indexation and use of multiple cutting edges, extending the service life before replacement.

Which dimensions and geometry should be noted? Key dimensions are a 0.8 mm corner radius, 4.76 mm thickness and a 16 mm inscribed circle size, with a 60° included angle and a 0° relief angle; the insert is supplied with a cylindrical hole for clamping.

How is compatibility with a holder determined? Compatibility depends on matching form, relief angle, tolerance class, fastening type, size and thickness; the system typically requires a compatible outer holder or boring bar plus shim and clamping screws.

What benefits does the CVD coating deliver? The CVD-coated carbide provides enhanced wear resistance and improved edge life under cast-iron cutting conditions, leading to more consistent surface finish and reduced tool-change frequency.
