SPMN 120408 T5115 — Indexable Turning Insert for Turning, Tungaloy

The SPMN 120408 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 carbide grade T5115
• ISO SPMN120408 geometry with 11° clearance
• Optimised for cast iron turning, 0.8 mm radius

Consistent edge life through CVD-coated carbide technology

The CVD-coated carbide substrate of this insert is engineered to combine surface hardness with substrate toughness, which results in improved wear resistance and reliable tool life on abrasive materials such as cast iron. The universal T5115 grade balances cutting-edge stability and abrasion resistance, reducing the frequency of tool changes and helping to maintain cycle times in series production. The modest 0.8 mm corner radius supports both stable roughing passes and controlled finishing, while the 11° clearance contributes to reduced cutting forces and better chip flow on interrupted or continuous cuts.

Easy integration in ISO tooling systems for predictable results

Supplied in the ISO SPMN120408 format, the insert matches established holder interfaces so compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The square shape and the insert’s dimensions ensure straightforward seating in standard external or internal turning holders; pairing with an appropriate backing shim and clamping set keeps the cutting edge secure for repeatable results. The 12 mm size and 4.76 mm thickness make this insert a compact, stable option for confined setups while preserving rigidity and vibration damping during cuts.

Practical shop-floor advantages and selection guidance

Delivered without an integrated chipbreaker, the insert allows selection of a chip control solution matched to the workpiece and process—choose a chipbreaker and cutting parameters that suit the chosen cast iron grade and machining operation. The square geometry provides multiple indexable corners for efficient edge utilisation, and the combination of CVD coating with a robust carbide body reduces unscheduled tool changes. For operations prioritising consistent surface finish and cycle-time reliability, this configuration supports a cost-effective balance between productivity and predictable tool life.

FAQ

What materials is this insert designed for?
The T5115 grade is a universal CVD-coated carbide formulated for cast iron machining; it offers a balance of wear resistance and edge stability suitable for many grey and nodular cast iron applications.

How is compatibility with tool holders ensured?
Compatibility depends on the insert form, clearance angle, tolerance class, clamping method, size and thickness; the ISO SPMN120408 designation provides a standard geometry that fits matching ISO holders.

Is a chipbreaker included with the insert?
No. The insert is supplied without a chipbreaker, allowing selection of a chip control solution tailored to the material and turning operation.

How many usable cutting edges does the square insert provide?
A square, 90° included-angle insert typically offers four indexable cutting corners, enabling economical use of each edge before replacement.

For which turning tasks is this insert most suitable?
This insert is optimised for both external and internal turning of cast iron where a reliable balance between wear resistance and edge stability is required; choose a matching holder and cutting data for best results.
