SPMN120308 T5115 — ISO indexable turning insert by Tungaloy, CVD‑coated carbide, 0.8 mm radius

A SPMN120308 T5115 indexable turning insert designed for external and internal turning, offering robust edge stability and broad suitability for cast iron components in production and repair environments

• ISO‑standardised geometry for holder compatibility
• CVD‑coated carbide for improved wear resistance
• Optimised for cast iron machining
• 0.8 mm corner radius for controlled cutting
• 11° clearance angle for reliable chip flow

Precision performance for consistent component quality

The insert delivers repeatable results through its ISO‑standard geometry and a proven carbide grade, enabling predictable cutting forces and surface finish in turning operations. The combination of CVD‑coated carbide and a defined corner radius reduces flank wear and maintains dimensional stability across series production runs. This focus on consistent performance supports cycle‑time control and fewer part reworks, which benefits shops aiming for stable output and measurable process reliability.

Clear guidance on compatibility and tool selection

Compatibility is determined by insert form, clearance angle, tolerance class, attachment style, size and thickness; the square 12 mm format and 3.18 mm plate thickness are matched to standard external holders and boring bars used in turning. Selecting the correct grade and chip former for the workpiece and machining stability ensures optimal results—this insert is specified without a chipbreaker and without a mounting hole, so matching the clamping kit and seating is essential for secure fixation and repeatable cutting performance.

Durable economy through reduced downtime and tool changes

With a balanced combination of wear resistance and edge stability, the grade offers longer in‑process life under typical cast iron cutting conditions, improving tool‑change intervals and lowering unit machining costs. The defined 0.8 mm corner radius helps control edge strength for interrupted cuts while the 11° clearance angle aids chip evacuation and reduces rubbing. Together these features contribute to higher productivity and predictable tool consumption rates in batch production and maintenance work.

FAQ

What materials is this insert designed for?
The SPMN120308 T5115 insert is intended primarily for machining cast iron, the CVD‑coated carbide grade providing a balanced combination of wear resistance and edge stability.

Which holder types are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, attachment and size; the square 12 mm format of this turning insert fits standard ISO holders designed for SPMN‑style inserts.

Does the insert include a chipbreaker or a mounting hole?
This grade is supplied without a chipbreaker and without a mounting hole; ensure the chosen clamping set and seat are appropriate for secure fixation of the insert.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength for interrupted and heavier cuts while maintaining acceptable surface finish, making the insert suitable for robust turning tasks.

Is the grade suitable for high‑speed cutting?
The CVD‑coated carbide construction of this cutting insert supports elevated cutting parameters in many cast iron applications, but actual speeds should be chosen according to machine capacity and fixture stability.
