CNMG190612 T5115 CNMG turning insert — CVD‑coated carbide, 80° rhombic — Tungaloy

A CNMG190612 T5115 ISO rhombic insert engineered for external and internal turning of cast iron, offering secure mounting via a cylindrical centre hole and a universal grade for stable machining.

• CVD-coated carbide universal grade T5115
• 80° rhombic geometry, 1.2 mm corner radius
• Double-sided chipbreaker for consistent chips
• Cylindrical centre hole for secure clamping

Consistent wear resistance for cast-iron turning

The T5115 grade is a CVD‑coated cemented carbide formulated as a universal solution for cast iron, combining wear resistance with cutting-edge stability. The coating enhances resistance to abrasive wear while preserving edge strength, which supports long, predictable tool life under typical turning parameters. The integrated double-sided chipbreaker controls chip formation across a range of feed rates, reducing the risk of built-up edge and improving process stability. This results in a more consistent surface finish and fewer interruptions for tool changes, which benefits batch production and single-part runs alike.

Robust geometry and ISO compatibility for secure clamping

The insert’s 80° rhombic geometry and 1.2 mm corner radius provide a favourable balance between cutting strength and accessibility for profile work. With a thickness of 6.35 mm and a cylindrical centre hole, the component is designed for rigid mounting in standard ISO toolholders; compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness. Where a reliable assembly is required, the complete system comprises the ISO insert, a matched external holder or boring bar, a support shim or clamping set and replacement screws. Clear specification of these parameters ensures secure fixation and repeatable positioning at every index.

Predictable productivity and straightforward process choice

Using a grade that is optimised for cast iron, combined with the insert’s geometry and chip control, delivers predictable tool life and reproducible surface quality—key factors for efficient machining cycles. The double‑sided design effectively halves the cost per cutting edge versus single‑sided alternatives, while the balanced properties of the coating and substrate reduce the likelihood of premature chipping. For best results, select a holder and cutting parameters that match the intended depth of cut and stiffness of the setup; stable machine conditions amplify the advantages of the insert and help secure shorter cycle times with consistent component quality.

FAQ

What materials is this grade intended for?
The CNMG190612 T5115 insert from Tungaloy is a universal grade optimised for cast iron, offering a balanced combination of wear resistance and edge stability suited to a wide range of grey and malleable cast irons.

Which geometry and mounting features does the insert have?
The insert features an 80° rhombic geometry with a 1.2 mm corner radius, a thickness of 6.35 mm and a cylindrical centre hole for secure mounting in ISO toolholders; matching of form, relief angle, size and fastening is required.

How does the CVD coating affect performance?
The CVD coating on the T5115 grade increases abrasive wear resistance while maintaining cutting-edge stability, which supports predictable tool life and improved surface finishes during turning of cast iron.

Is the insert reversible and what is the advantage?
The insert is double-sided with chipbreakers on both cutting faces, allowing indexing to a fresh edge and effectively doubling the number of usable cutting edges for cost-efficient machining.

Can this insert be used for internal turning as well as external turning?
Yes, the design is suitable for both external and internal turning when paired with an appropriate holder or boring bar that provides the required rigidity and clearance.
