TNMA 220404 T5115 indexable insert for Turning — Tungaloy, CVD-coated carbide, 60° triangle

A TNMA220404 T5115 indexable turning insert designed for ISO-compliant external and internal turning, offering a universal grade optimised for cast iron machining.

• CVD-coated carbide grade T5115
• ISO TNMA 220404 geometry
• 60° triangular shape, 0.4 mm radius
• Suitable for cast iron machining

Reliable cutting performance for cast iron applications

The combination of a CVD-coated surface and a wear-resistant carbide substrate delivers a balanced mix of edge stability and abrasion resistance, particularly suited to cast iron. This grade is engineered to provide consistent tool life where abrasive graphite and interrupted cuts are common, which reduces changeover frequency and supports continuous production. By selecting a universal grade, operators benefit from a single insert solution for a wide range of turning tasks, lowering inventory complexity while maintaining process reliability.

Precise geometry and system compatibility for repeatable results

The insert’s ISO TNMA 220404 designation denotes the triangular 60° geometry, 22 mm size and standardised mounting interface, which simplifies toolholder selection. With a 0.4 mm corner radius and 4.76 mm thickness, the component offers a predictable cutting edge for dimensional control and surface finish. Compatibility depends on holder form, relief angle, tolerance class, fixing method, size and thickness; the system typically comprises the indexable insert, a matched external holder or boring bar, a backing shim/clamping set and replacement screws. The insert’s cylindrical hole facilitates secure fastening and stable clamping, enhancing repeatability in batch production.

Practical advantages that streamline machining

Using an ISO-compliant triangular insert reduces setup time and eases tool management across different machines. The absence of an integrated chipbreaker means chip control must be matched to cutting conditions and workpiece material; however, the T5115 grade offers robust edge integrity for many cast iron operations, enabling higher cutting speeds and consistent surface quality. The standardised format supports quick index changes and reduces downtime, while the insert’s geometry provides accessibility in both external turning and internal boring operations.

FAQ

What materials is this insert suitable for?
The TNMA220404 T5115 insert is formulated primarily for cast iron machining; the CVD-coated carbide provides wear resistance suitable for common cast iron turning operations.

How does the TNMA 220404 geometry affect tool selection?
The ISO TNMA 220404 geometry (60° triangle, 22 mm) ensures compatibility with standard TNMA holders; select a holder that matches the relief angle, tolerance class and fixing method for correct fitment.

Is a chipbreaker integrated in this design?
This insert is supplied without a chipbreaker, so chip evacuation must be managed through cutting parameters and the chosen clamping/holder configuration when using this Tungaloy grade.

Can the insert be used for both external and internal turning?
Yes; the TNMA220404 T5115 indexable insert is suitable for both external turning and internal boring, provided the chosen holder offers the necessary access and rigidity.

What is the manufacturer SKU and article number for ordering?
Order references are Manufacturer SKU TUN6853041 and Article number 6853041; when specifying, include the grade T5115 and the ISO designation TNMA220404.
