SNMG120408 T5115 indexable insert for turning — Tungaloy, CVD-coated carbide, square form

SNMG120408 T5115 Tungaloy insert is an ISO-standard indexable turning insert designed for reliable external and internal turning of cast iron components.

• CVD-coated carbide for wear resistance
• Double-sided chipbreaker for reliable chip control
• Square ISO form 12 with 90° cutting angle
• Cylindrical hole and 0° clearance angle

Longer tool life and consistent edge stability for cast iron turning

The SNMG120408 T5115 insert combines a CVD-coated carbide substrate with a balanced grade tailored for cast iron, delivering improved wear resistance and edge retention under intermittent and continuous cuts. The corner radius 0.8 mm supports stable cutting forces and contributes to a consistent surface finish, while the square form and 90° cutting angle enable straightforward orientation in common external-holding setups. By prioritising material-matched grade selection, the insert reduces unscheduled tool changes and supports predictable tool-life planning.

Secure ISO fitment and straightforward system integration

Compatibility with standard ISO holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the SNMG120408 is supplied as an ISO-form insert with a cylindrical hole for secure clamping. The recommended system build includes the indexable insert, a suitable external holder or boring bar, a shim or clamp pack and replacement screws to maintain repeatable seating and concentricity. Explaining the CVD layer in simple terms: a fine, thin ceramic coating applied by chemical vapour deposition that enhances surface hardness and temperature resistance without compromising the toughness of the carbide core.

Improved process security and chip control for higher productivity

The double-sided chipbreaker promotes predictable chip formation and evacuation when machining grey and nodular cast iron, reducing recutting and downtime. With 0° clearance angle and an optimised chip control geometry, the insert supports stable cutting conditions and reproducible part quality, which translates into an improved cost-per-part ratio. In practice, consistent chip shape and edge stability reduce the need for frequent operator intervention and help maintain cycle times in both single-pass and multi-pass operations.

FAQ

What materials is this insert optimised for?
The SNMG120408 T5115 insert is optimised for machining cast iron, offering a balanced combination of wear resistance and edge stability for grey and nodular cast iron.

Is the insert compatible with standard ISO holders?
Yes, the SNMG120408 follows ISO form and dimensions; compatibility depends on holder form, tolerance class, fastening and thickness matching the insert specifications.

What does the T5115 designation indicate?
T5115 denotes a CVD-coated carbide grade developed for broad cast-iron applications, focusing on a balance between wear resistance and cutting-edge stability.

How does the double-sided chipbreaker benefit the process?
The double-sided chipbreaker improves chip control and evacuation, reducing recuts and stabilising cutting forces to help maintain consistent surface quality and cycle times.

Can the insert be used for both external and internal turning?
Yes, the ISO indexable form and geometrical features make the insert suitable for both external and internal turning operations when mounted in the appropriate holder.
