CNMG190612 T5115 indexable turning insert — Tungaloy, 80° rhombic geometry, 1.2 mm nose radius

CNMG190612 T5115 is an ISO‑standard indexable insert for turning applications, principally developed for machining cast iron with a balance of wear resistance and edge stability.

• CVD-coated cemented carbide grade T5115
• Universal grade optimised for cast iron
• ISO‑standard CNMG190612 geometry
• Double-sided chipbreaker, cylindrical hole

High-capacity grade for consistent cast iron machining

The T5115 grade is a CVD-coated cemented carbide developed as a universal solution for machining cast iron, delivering an even balance between wear resistance and edge integrity. In practice, this creates stable chip formation and predictable tool life under a range of cutting conditions, which translates into fewer interruptions on the shop floor and improved process reliability. The coating reduces flank wear at moderate to high cutting speeds, helping to maintain component dimensional accuracy over longer tool life.

Geometry and mounting that simplify tool management

The CNMG190612 geometry features an 80° approach angle and a rhombic profile with a 1.2 mm nose radius, providing a versatile combination of accessibility and edge strength for both external and internal turning. The plate is 6.35 mm thick and supplied with a cylindrical hole, enabling secure clamping in compatible holders. A 0° clearance angle and double-sided chipbreaker construction mean the insert can be indexed to a fresh cutting edge, reducing inventory needs and improving uptime. Compatibility to a holder is ensured by matching form, free angle, tolerance class, fastening method, size and thickness.

Practical gains: productivity, reduced downtime and straightforward selection

Using a CVD-coated universal grade like T5115 supports higher productivity in many cast iron applications by extending intervals between tool changes and delivering consistent surface finish. Selecting the appropriate chipbreaker and grade according to workpiece material and machine stability is key: a double-sided chipbreaker suits a variety of chip control requirements and can be used where reversibility and economy are priorities. The combination of cemented carbide core, protective coating and ISO geometry provides a straightforward route to optimised cutting data and lower total machining costs through longer tool life and stable chip control.

FAQ

What materials is this insert designed for? The CNMG190612 T5115 insert from Tungaloy is primarily specified for machining cast iron, offering a universal balance of wear resistance and edge stability suitable for many grey and nodular iron applications.

Is the insert reversible and how does that affect stock management? Yes — the insert has a double-sided chipbreaker, which allows indexing to a fresh edge; this reduces the number of distinct items required in tool inventory and improves economic efficiency.

Which holders are compatible with this ISO insert? Compatibility depends on matching the rhombic form, 80° approach angle, tolerance class, fastening method, size and thickness; the CNMG190612 format with a cylindrical hole fits standard ISO indexable turning holders designed for this geometry.

How does the CVD coating benefit machining performance? The CVD-coated cemented carbide of the T5115 grade reduces flank wear and supports stable chip formation at moderate to high cutting speeds, resulting in more consistent surface finish and extended tool life compared with uncoated grades.

Can this insert be used for internal turning as well as external turning? Yes — the insert is suitable for both external and internal turning operations, provided the chosen holder and tool overhang match the application and machine stability.
