SPMN 090308 T5115 SPMN — Indexable turning insert for turning, 90° included angle, Tungaloy

A SPMN090308 T5115 indexable turning insert for ISO-standard external and internal turning, optimised as a universal grade for cast iron machining.

• ISO-standard SPMN090308 geometry
• CVD-coated cemented carbide grade T5115
• 0.8 mm corner radius for stable cutting
• Square form, 90° included angle

Consistent wear resistance for productive turning

The CVD-coated cemented carbide composition of this insert delivers a balanced combination of wear resistance and edge stability, which directly supports longer tool life and fewer interruptions in production. As a universal grade optimised for cast iron, the substrate and coating are selected to reduce flank wear and maintain a consistent cutting edge under typical turning conditions. This reliability helps to sustain cycle times and improve part reproducibility without frequent index changes.

Geometry tuned for precision and surface quality

With a 0.8 mm corner radius and an 11° clearance angle, the insert geometry promotes controlled chip formation and predictable cutting forces. The square form and 90° included angle allow for versatile toolholder options and straightforward index rotation to compensate wear. These geometric choices translate into finer surface finishes and stable tool behaviour during both finishing and medium-roughing passes, particularly when paired with appropriately rated holders and feeds.

Practical system advantages and holder compatibility

Compatibility with holders depends on form, clearance angle, tolerance class, fastening and plate thickness; the ISO-standard construction ensures interchangeability across many clamping systems. The plate thickness of 3.18 mm and the absence of a hole or chipbreaker mean the insert is intended for positive clamping in standard seats and for users who prefer customised chip control via holder geometry rather than integral breakers. Specifying the correct clamp and shim delivers consistent seating and repeatable centration.

Application focus and material coverage

Designed primarily for turning, the universal grade excels when machining cast iron, offering balanced performance across interrupted to continuous cuts. The absence of a built-in chipbreaker requires attention to feed and cutting parameter selection, but this also enables flexibility: the same geometry can be used for a range of turning tasks where predictable chip flow and edge strength are priorities. For operations where enhanced chip control is required, pairing the insert with a holder featuring dedicated chip control geometry is recommended.

FAQ

What workpieces are best suited to this insert?
The SPMN090308 T5115 insert is optimised for cast iron turning and performs well on a range of cast-iron components where a balance of wear resistance and edge stability is required.

Does this insert include a chipbreaker?
No, this indexable insert is supplied without a chipbreaker; chip control should be managed via the holder geometry and cutting parameters.

Which holder features are required for correct clamping?
Compatible holders must match the ISO form, clearance angle (11°), tolerance class, fastening and plate thickness; positive clamping with the correct shim and screw ensures repeatable seating.

What benefits does the T5115 grade bring?
The T5115 CVD-coated grade provides a combination of wear resistance and edge stability tailored to cast-iron applications, reducing flank wear and extending reliable cutting performance.

Is the insert suitable for internal and external turning?
Yes, the ISO-standard geometry and 90° included angle make the insert suitable for both external and internal turning operations when used with matching holders.
