SPMN SPMN120412 T5115 indexable turning insert — Tungaloy, CVD-coated cemented carbide

SPMN120412 T5115 is an ISO-standard indexable insert designed for external and internal turning, optimised for machining cast iron with a balanced mix of wear resistance and cutting-edge stability

• CVD-coated cemented carbide grade T5115
• ISO-standard SPMN120412 geometry
• Balanced wear resistance and edge stability
• Square 12 mm plate with 11° clearance angle

Precision and economy for turning cast iron

The insert is produced as an ISO-standard turning plate and is supplied in a CVD-coated cemented carbide grade that is optimised for machining cast iron. The chosen grade provides a measured compromise between wear resistance and edge stability, which reduces the frequency of index changes under stable conditions. The geometry — a square plate with a 1.2 mm corner radius and a 11° clearance angle — supports robust clamping and predictable chip flow during both external and internal turning operations. Compatibility with toolholders is determined by form, clearance, tolerance class, clamping method, size and thickness, so checking these parameters ensures reliable performance.

Practical compatibility and handling in the workshop

Designed as part of an ISO turning insert system, this plate is simple to integrate into existing holders when dimensions and clamping style match. The plate thickness of 4.76 mm and square 12 mm size make it suitable for a broad range of standard external holders and boring bars. The insert is supplied without a hole and without a chipbreaker, which is beneficial in stable setups where a clean cutting edge and uninterrupted chip flow are preferred. When a chip control feature is required, alternative grades or chipbreaker versions should be selected; otherwise, the present geometry gives consistent contact conditions and good repeatability.

Process benefits and selection guidance

Using this CVD-coated plate supports longer tool life in many cast-iron operations and contributes to predictable surface results. The absence of an aggressive chipbreaker and the robust edge geometry mean the insert performs well in steadier machining scenarios; for interrupted cuts or unstable setups, choosing a plate with an adapted chipformer or different grade can be advantageous. The T5115 grade is a universal choice for cast iron owing to its balanced properties, enabling a pragmatic compromise between production throughput and tool consumption. If additional technical data or cutting-parameter recommendations are required, Metav Werkzeuge can advise on the ideal matching holder and process window.

FAQ

What materials is this insert suited for?
The SPMN120412 T5115 insert from Tungaloy is intended primarily for machining cast iron; the T5115 grade balances wear resistance and edge stability for that material class.

How is holder compatibility determined for this ISO insert?
Compatibility is governed by the insert form, clearance angle, tolerance class, clamping method, size and thickness; the SPMN120412 geometry must match the chosen holder for secure clamping.

What does the absence of a chipbreaker imply for machining?
The lack of a chipbreaker on the SPMN120412 plate means a clean cutting edge and unobstructed chip flow under stable cutting conditions; for enhanced chip control, select a plate with an integrated chipformer.

Can this insert be used for internal turning as well as external turning?
Yes, the ISO-standard design and square geometry allow use in both external and internal turning operations when combined with a suitably dimensioned boring bar or holder.

What advantages does the CVD coating provide on this grade?
The CVD-coated T5115 grade improves surface hardness and wear resistance at elevated temperatures, contributing to longer tool life and consistent cutting behaviour during turning of cast iron.
