CNMG 090404 T515 ISO turning insert by Tungaloy — for economical turning

A CNMG090404 T515 ISO turning insert optimised for productive external and internal turning of cast iron, featuring a rhombic form and a double-sided chipbreaker for reliable chip control.

• CVD-coated carbide T515 grade
• Double-sided chipbreaker
• Rhombic CNMG form 09

Consistent economy for cast-iron turning and stable chip formation

The combination of a CVD-coated surface and a wear-resistant carbide substrate gives predictable tool life and low total machining costs when facing cast-iron work. The T515 grade is specifically selected for economic machining of grey and nodular cast iron, offering a balance between edge strength and wear resistance. With a controlled cutting geometry, shops benefit from reduced regrinding frequency and more consistent component tolerances, supporting higher throughput in batch production.

Geometry and edge preparation that improve surface finish and process reliability

The rhombic CNMG form with a 0.4 mm nose radius and 0° clearance angle supports both finishing and light semi-finishing operations while preserving edge robustness. The insert's double-sided chipbreaker promotes short, manageable chips at typical turning feeds for cast iron, reducing the need for secondary chip handling measures. The insert thickness of 4.76 mm contributes to secure clamping and repeatable seating, helping to maintain surface quality across repeated tool indexings.

System compatibility and practical mounting considerations

Designed to conform to ISO specifications for turning inserts, the component fits standard ISO holders where form, relief angle, tolerance class, fastening method, size and thickness match. The insert is supplied with a cylindrical hole to suit holes-and-screw clamping systems and is intended for use with a matching outer holder or boring bar, backing pad/clamp kit and replacement screws as part of the system. Selecting an appropriate holder and stable setup will maximise life and repeatable results when machining interrupted cuts or less rigid setups.

Application guidance and process advantages in production environments

For productive turning of cast-iron components, the CVD-coated T515 insert provides a cost-effective solution where consistent chip control and tool life are required. Its geometry supports flexible use across external and internal turning; the ISO designation assists in quick tool selection and procurement. Where higher stability and uninterrupted cuts are available, the grade typically yields improved tool life and process security, making it suitable for medium to high-volume workshops seeking steady output and lower tooling costs.
