TNMG160408 T5115 TNMG indexable turning insert by Tungaloy — CVD-coated carbide, universal grade for cast iron

TNMG160408 T5115 is a CVD-coated indexable turning insert designed for turning applications in cast iron; triangular geometry and ISO conformity ensure predictable mounting and repeatable performance

• CVD-coated carbide T5115 universal grade
• ISO TNMG 160408 triangular insert form
• Double-sided chipbreaker for stable cutting
• 0.8 mm corner radius for robust edge life

Consistent wear resistance for stable production

The combination of a CVD-coated surface and a hard carbide substrate delivers a reliable balance between wear protection and edge robustness. This leads to extended tool life under interrupted or continuous cuts and reduces the need for frequent indexing, improving overall machining uptime. The specified grade is optimised for cast iron, so the cutting edge maintains form while offering repeatable surface quality — a clear productivity advantage where process stability is key.

Predictable fit and easy integration with ISO toolholders

Produced to the ISO TNMG 160408 geometry, the insert matches the dimensional and form standards most commonly used in modern turning systems. Compatibility with a holder is determined by form, relief angle, tolerance class, clamping method, size and thickness, all reflected in the insert’s design. The triangular plate with a 0° relief and a cylindrical hole simplifies clamping checks and reduces setup time, enabling predictable seating and stable cutting forces for reproducible results in serial production.

Effective chip control and improved surface reliability

A double-sided chipbreaker combined with a 0.8 mm corner radius gives a controlled chip formation and consistent cutting action on external and internal turning tasks. The chipformer design reduces recutting and risk of built-up edge, which supports better surface finish and fewer interruptions. For operations prioritising throughput, this geometry helps to maintain tool life and dimensional accuracy, translating into steadier cycles and lower rework rates.

FAQ

Is this insert suitable for cast-iron machining? Yes. The TNMG160408 T5115 insert uses a T5115 CVD-coated carbide grade specifically balanced for cast-iron applications, providing wear resistance and edge stability.

Can the insert be used for both external and internal turning? Yes. The design and chipbreaker allow application in both external and internal turning operations, making the TNMG160408 T5115 versatile for workshop tasks.

What does the double-sided chipbreaker mean in practice? A double-sided chipbreaker offers controlled chip formation on both indexed faces, extending usable edges and enhancing process reliability for the TNMG160408 T5115 insert.

How does ISO conformity help in tool selection? ISO TNMG 160408 geometry ensures dimensional compatibility with standard holders; the insert’s form, size and thickness aid predictable clamping and repeatable set-up.

What advantages does the 0.8 mm corner radius provide? A 0.8 mm radius gives a compromise between edge strength and finish capability, improving resistance to chipping while still permitting acceptable surface quality in many turning tasks.
