SPMW SPMW120408 T5115 – Indexable insert for turning | Tungaloy

SPMW120408 T5115 is a square ISO indexable insert designed for turning operations, offering a universal CVD‑coated carbide grade optimised for cast‑iron machining.

• ISO‑compliant square insert
• CVD‑coated universal grade T5115
• Suitable for cast iron machining
• Cylindrical hole with 40°–60° countersink

Higher uptime through balanced wear and edge stability

The CVD‑coated carbide grade T5115 combines wear resistance with edge toughness, which reduces unexpected tool changes and supports more stable cycle times in batch production. For turning applications on cast iron, this balance delivers a reliable compromise between flank wear resistance and edge strength, helping to maintain tolerances longer. The 0.8 mm corner radius increases insert strength at the cutting edge, improving resistance to chipping during interrupted cuts while still permitting acceptable surface finishes on external and internal faces.

Easy integration into standard tooling systems

As an ISO‑standard insert, the SPMW120408 geometry ensures predictable fitting in compatible square holders and boring bars; compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness. The insert’s 11° clearance angle and cylindrical hole with one‑sided 40°–60° countersink provide secure clamping and repeatable seating in the pocket. With a nominal size of 12 mm and a plate thickness of 4.76 mm, the component integrates into common turning tool systems and is accompanied in practice by a suitable external holder or boring bar, shim/locking kit and replacement screws for straightforward assembly.

Material focus and process security for cast‑iron work

Designed as a universal grade for cast iron, this insert benefits from coatings applied by chemical vapour deposition to withstand abrasive graphite in grey cast iron and to protect the cutting edge in austempered or nodular grades. The absence of a chipbreaker (no chipbreaker fitted) means chip control must be managed by selecting the correct feed and holder geometry; however, the robust substrate and coating combination offer predictable wear behaviour and repeatable surface results. Together with stable clamping and the correct radial depth of cut, the insert supports higher process security and consistent part quality in production environments.

FAQ

What materials is this insert best suited for?
The Tungaloy SPMW120408 T5115 insert is formulated as a universal grade for cast iron, providing balanced wear resistance and cutting‑edge stability for a wide range of cast‑iron alloys.

Does the insert include a chipbreaker?
No; the SPMW120408 is supplied without a chipbreaker, so chip control is achieved through feed, depth of cut and appropriate holder geometry when using this Tungaloy indexable insert (SKU 6862100‑Tungaloy).

Which holders are compatible with this ISO insert?
Compatibility is determined by insert form, relief angle, tolerance class, clamping method, size and thickness. The SPMW120408 fits standard square ISO pockets when those parameters match.

What advantage does the CVD coating provide?
The CVD coating on the T5115 grade increases surface hardness and oxidation resistance, improving wear life when machining abrasive graphite‑containing cast iron and supporting consistent performance under production loads.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius enhances edge strength and reduces chipping risk in interrupted cuts, while still allowing acceptable surface finishes for general turning tasks.
