SNMA120408 T515 ISO turning insert for external and internal turning — Tungaloy

SNMA120408 T515 is an ISO‑standard square turning insert designed for economical, high‑productivity machining of cast iron using a CVD‑coated carbide grade.

• CVD‑coated carbide grade T515 for cast iron
• Square ISO insert 90° with 0.8 mm corner radius
• Cylindrical‑hole fixing for secure clamping
• Compatible with ISO turning holders and toolholders

Higher productivity through adapted grade and geometry

The combination of a CVD‑coated carbide grade and an ISO square geometry delivers a clear productivity advantage when machining cast iron. The coating increases wear resistance and thermal stability, which extends tool life and reduces changeover frequency. With a 0.8 mm corner radius and a 90° approach, the insert provides predictable cutting forces and consistent contact conditions, allowing machining parameters to be optimised for greater material removal rates without sacrificing surface integrity.

Secure clamping and repeatable cutting performance

A cylindrical locating hole and standardised fixing ensure the insert is held securely in the seat, which reduces vibration and improves surface finish. The ISO form and tolerance classes mean the component is compatible with a wide range of external holders and boring bars; this simplifies tool inventory and helps standardise setups on the shop floor. The result is more repeatable machining cycles and fewer rejects due to geometric variation.

Simple selection for cast‑iron turning tasks

The grade is specifically intended for economical machining of cast iron, making the selection process straightforward: choose this grade where interrupted cuts are moderate and stable setups are available. The absence of an integrated chipbreaker in this variant focuses the benefit on stable chip formation driven by the geometry and process parameters. For users unfamiliar with the terminology: CVD coating refers to a chemical vapour deposition layer that improves surface hardness and heat resistance, while the corner radius influences edge strength and profile accuracy.

System compatibility and maintenance benefits

The insert is supplied in the ISO designation SNMA120408 and fits established holder systems when the correct form, clearance, tolerance and clamping arrangement are observed. The 4.76 mm plate thickness and square plate form deliver robust support in the pocket. Fewer tool changes, thanks to the grade’s wear behaviour, directly reduce downtime and contribute to lower total machining costs. For everyday workshop planning, this means longer uninterrupted runs and a predictable maintenance cadence.

FAQ

What materials is this insert intended for?
The SNMA120408 T515 insert is specified for the economical machining of cast iron; the T515 grade and CVD‑coated carbide backing provide wear resistance suited to that material group.

Which clamping style is required for this insert?
A cylindrical‑hole clamping arrangement is used for this square ISO insert; it is designed to be fixed with the matching screw, seat and pad as found on ISO‑compliant holders.

How does the 0.8 mm corner radius affect machining?
The 0.8 mm radius increases edge strength and helps absorb intermittent cutting loads, improving edge life and producing a consistent surface profile on turned components.

Is a chipbreaker included with this insert?
This version does not include an integrated chipbreaker; the geometry and process parameters should be chosen to ensure controlled chip formation during turning.

Can the insert be used for both external and internal turning?
Yes, the SNMA120408 design is suitable for both external and internal turning when paired with the appropriate ISO external holder or boring bar.
