SNMG 120412 T5105 ISO indexable turning insert for turning, Tungaloy

The SNMG120412 T5105 is an ISO‑standard indexable turning insert engineered for high‑speed machining of cast iron under stable setup conditions.

• CVD‑coated carbide grade T5105
• Optimised for high‑speed cast iron turning
• Double‑sided geometry with 1.2 mm radius
• ISO‑standard SNMG 120412, 90° cutting angle

Reliable wear performance for productive turning

The insert’s CVD‑coated carbide composition (T5105) provides a hard, wear‑resistant surface that reduces flank and crater wear during high‑speed operations on cast iron. This leads to longer tool life and fewer index changes, which improves machine uptime and lowers overall process costs. The 1.2 mm corner radius and 90° cutting angle support robust engagement and predictable chip formation, while the 4.76 mm thickness contributes to stiffness and vibration resistance in stable setups.

Easy integration into ISO tooling systems

Compatibility is determined by the insert’s shape, clearance angle, tolerance class, fixing and size; the SNMG form and ISO designation simplify selection of matching toolholders and clamping sets. The insert is supplied with a cylindrical hole for secure fastening and is double‑sided, offering two usable cutting edges per index. Where process reliability matters, pairing the insert with a correctly specified holder and clamp set reduces run‑out and improves repeatability, particularly for external and internal turning tasks.

Practical advantages for everyday workshop use

For production shops seeking consistent surface finishes and efficient chip control, the optimised chipbreaker geometry and the grade’s behaviour under stable conditions translate into predictable material removal and fewer process interruptions. The system approach — insert, holder, underlay/clamp and replacement screws — allows quick reconditioning of tool assemblies. This insert is ideal for turning operations where repeatability, productivity and low maintenance effort are priorities.

FAQ

What materials is this insert best suited for?
The SNMG120412 T5105 insert is optimised for high‑speed machining of cast iron; the CVD‑coated T5105 grade provides improved wear resistance for this material group.

How many cutting edges are available per insert?
The insert is double‑sided, providing two usable cutting edges per index before reconditioning or disposal.

Does the insert fit standard ISO toolholders?
Yes, the SNMG form and ISO designation ensure compatibility with standard ISO indexable turning holders, subject to matching the insert thickness, hole style and tolerance class.

What is the corner radius and how does it affect performance?
The corner radius is 1.2 mm; this radius balances strength and surface finish, enabling stable cutting and good tolerance to interrupted cuts when set up correctly.

Is the cutting edge suitable for internal as well as external turning?
The geometry and 90° cutting angle make the insert suitable for both external and internal turning operations when used with the appropriate holder and support.
