Stable cutting and reliable compatibility for reduced downtime

The triangular indexable insert offers a compact design that supports repeatable seating and clamping, reducing setup time and the risk of misalignment. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; this ensures precise fitment when the matching TCMT holder is used. The predictable interface between insert and seat contributes directly to process stability, lowering the likelihood of vibration-induced tool wear and improving cycle-to-cycle consistency.

Coating and grade designed for cast iron productivity

The CVD-coated T5115 grade combines wear resistance with cutting edge robustness, making it suitable as a universal choice for grey cast iron. Chemical vapour deposition (CVD) applies a hard, abrasion-resistant layer to the carbide substrate, which slows flank and crater wear under typical turning stresses. For users unfamiliar with coating terminology: the coating extends tool life by protecting the cutting edge from heat and abrasion, enabling longer uninterrupted production runs and fewer insert changes.

Geometry and edge design for controlled chip formation

With a 0.4 mm corner radius and a 7° relief angle, the insert balances edge strength and the need for a controlled cutting edge for finishing or light roughing passes. The single-sided chipbreaker and the triangular shape provide three indexed cutting corners per insert, improving economy per edge. The central hole with a matched countersink secures positive clamping and helps transmit cutting forces evenly, which benefits surface finish and repeatability in turning operations.

Practical application scenarios and process benefits

The insert is conceived for both external and internal turning operations where cast iron is the predominant workpiece material. Selecting this geometry and T5115 grade typically results in stable tool life and consistent surface quality, which supports higher uptime and predictable planning for tool replacements. For workshops seeking a balance of performance and cost-efficiency, this carbide insert provides a reliable baseline that can be paired with appropriate holders and parameter optimisation to increase throughput.

FAQ

Is this insert suitable for cast iron turning?
The TCMT110204 T5115 indexable turning insert by Tungaloy is a universal grade optimised for grey cast iron, combining wear resistance and edge stability for reliable performance in cast iron applications.

How is compatibility with the tool holder determined?
Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness; matching the TCMT profile and using the correct holder ensures secure clamping and accurate seating for the Tungaloy insert.

What does the T5115 grade offer compared with other grades?
T5115 is a CVD-coated carbide grade that balances wear resistance and edge stability, making it suited to a wide range of cast iron turning tasks where process stability is important.

How many cutting edges are available per insert and how does the hole affect clamping?
The triangular form provides three indexed cutting corners, and the central hole with a countersink secures the insert against the seat and distributes clamping forces to maintain positional repeatability during turning.
