SNMG 120408 T515 turning insert by Tungaloy — square ISO indexable insert for cast-iron turning, CVD-coated

SNMG120408 T515 Tungaloy-Wendeplatte is a square ISO indexable insert designed for external and internal turning of cast iron where stable chip formation and economic machining are required

• CVD-coated carbide for cast-iron machining
• Double-sided chipbreaker for consistent chip control
• Square form with 90° insert angle for robust cuts

Reliable performance through optimised chip control and coating

The combination of a CVD-coated carbide grade and a specifically engineered double-sided chipbreaker delivers reproducible chip formation when machining cast iron. That results in fewer interruptions, reduced rework and more predictable tool life, which supports higher machine utilisation. Compatibility with standard ISO holders is defined by form, clearance angle, tolerance class, attachment method, size and thickness, so selecting a matching clamping set and screw is essential for achieving the stated performance.

Precision geometry for stable turning and improved surface finish

A 0.8 mm nose radius and a 90° insert angle provide mechanical stability during both roughing and finishing operations. The 4.76 mm plate thickness and square plate form reduce vibration under heavier cuts, translating into improved dimensional accuracy and a consistent surface texture on the component. For users new to indexable tooling, the nose radius influences cutting forces and small radii like 0.8 mm are commonly chosen where a balance between edge strength and finish quality is needed.

Practical system considerations and application choice

The insert is supplied with a cylindrical hole for secure locating on appropriate holders and is double-sided, which doubles the available cutting edges and contributes to cost efficiency per edge. It is particularly suited to turning operations on cast iron when the process demands stable chips and economical throughput. Selection of the matching holder, support pad and screw must account for the insert’s ISO geometry and thickness to ensure correct clamping and repeatable performance.

FAQ

What materials is this insert suited for?
The SNMG120408 T515 insert is formulated for economical machining of cast iron, thanks to its T515 CVD coating and chipbreaker geometry.

How many cutting edges are available per insert?
The insert is double-sided, offering two usable edges per indexed face and therefore multiple cutting edges before replacement is necessary.

Which holder features are required for correct mounting?
Compatibility is determined by insert form, clearance angle, tolerance class, attachment method, size and thickness; choose an ISO-compatible square insert holder and the correct clamping set.

What does the T515 grade provide in practice?
T515’s CVD-coated carbide delivers stable chip formation and good wear resistance for cost‑effective cast-iron machining and steady productivity.

Is the insert compatible with internal as well as external turning?
Yes, the SNMG geometry with a 90° insert angle is suitable for both external and internal turning applications, provided a matching boring bar or internal holder is used.
