TNMA220408 T5105 – TNMA ISO turning insert for turning, CVD-coated carbide (Tungaloy)

The TNMA220408 T5105 is an ISO-standard triangular turning insert designed for machining cast iron at higher cutting speeds, offering a balance of wear resistance and predictable performance in stable set-ups.

• CVD-coated carbide T5105
• 60° triangular geometry
• Corner radius 0.8 mm
• For high-speed cast iron turning

Stable wear behaviour for consistent production

The CVD-coated carbide composition of the T5105 grade provides a wear-resistant contact surface that resists built-up edge and thermal degradation during sustained turning. In practice this means longer intervals between index changes and more predictable component tolerances. For production environments where repeatability is essential, the combination of the grade and coating supports steady performance and reduced process variation, contributing to more reliable cycle times.

Geometry and mounting that support machining accuracy

With a 60° triangular shape and a corner radius of 0.8 mm, the insert delivers a versatile cutting geometry suitable for both external and internal turning operations. The insert is supplied with a cylindrical hole, enabling secure clamping in compatible TNMA holders; compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness. Correct seating and clamping reduce vibration and help maintain dimensional accuracy during finishing passes.

Application-focused advantages for cast iron turning

This grade is specified for high-speed machining of cast iron under stable cutting conditions. Where workpiece material, cutting strategy and machine rigidity align, the insert gives a favourable combination of wear resistance and edge stability. Since this insert is supplied without an integrated chipbreaker, select the appropriate holder or external chip-control measures according to material type and chip form to maintain surface quality and evacuate swarf effectively.

Practical selection and operational guidance

When integrating this insert into a tool system, ensure the selected holder matches ISO form and the insert thickness of 4.76 mm and seat geometry. The nominal insert size is 22 mm and the included angle is 60°, which together determine approach angle and cutting engagement. For operations that demand improved edge life, consider tooling parameters and coolant strategy compatible with CVD-coated carbide grades; modest adaptations to feed or speed can extend usable life without sacrificing surface finish.

FAQ

What materials is this insert intended for?
The TNMA220408 T5105 insert is specified for high-speed machining of cast iron; the grade and CVD coating favour wear resistance during such applications.

Is the insert compatible with standard TNMA holders?
Compatibility depends on holder form, relief angle and tolerance class; the insert requires a matching TNMA clamping seat and the correct fastening and thickness (4.76 mm).

Does the insert include a chipbreaker?
This insert is supplied without a chipbreaker; chip control should be achieved via holder geometry or external measures suited to the workpiece material.

What is the corner radius and how does it affect the cut?
The corner radius is 0.8 mm; a larger radius can improve edge strength and surface finish but may increase cutting forces—choose feeds and depths accordingly.

Which SKU identifies this product for ordering?
Order using SKU 6850312-Tungaloy or the manufacturer SKU TUN6850312 to ensure the correct TNMA220408 T5105 turning insert is supplied.
