SNMG 120412 T5125 indexable turning insert by Tungaloy — ISO profile, CVD‑coated carbide for turning

The SNMG 120412 T5125 is a CVD‑coated carbide indexable insert designed for external and internal turning, optimised for cast‑iron applications and less stable cutting conditions

• CVD‑coated carbide grade T5125
• Optimised for cast iron interrupted cuts
• ISO SNMG 120412 profile for standard holders
• Double‑sided with cylindrical hole

Stable chip control for interrupted turning

The combination of a CVD‑coated surface and a tougher carbide substrate delivers predictable chip formation even under intermittent cutting. This results in fewer vibrations and a reduced tendency for built‑up edge, which supports consistent surface finish and extended tool life. The T5125 grade is formulated to tolerate impacts and instability typical of interrupted cuts in cast iron, so the machining process becomes more reliable and less dependent on perfect fixturing or exceptionally rigid set‑ups.

Geometry tailored for repeatable results

A precisely ground geometry with a 1.2 mm corner radius and an included angle of 90° provides a good balance between strength and cutting edge accessibility. The insert’s 0° clearance and square outline are adapted to common turning tasks, offering a robust cutting edge for medium to heavy engagement. The ISO SNMG120412 form ensures interchangeability with standard SNMG holders, enabling rapid replacement and predictable positioning—benefits that translate directly into reduced downtime and easier process control.

Easy integration into existing tool systems

Compatibility with holders depends on form, clearance angle, tolerance class, fastening and thickness; the square SNMG format and the cylindrical hole support secure clamping in a wide range of external and internal turning holders. The insert’s thickness of 4.76 mm and standard size designation simplify procurement and stocking for production environments. This compatibility reduces the need for special adapters and helps maintain steady production flow when changing grades or chipbreakers.

Designed for robust performance and low maintenance

The double‑sided design effectively doubles the usable cutting edges, increasing economy per insert and lowering tool change frequency. The combination of a wear‑resistant substrate and the CVD coating improves edge stability and wear resistance, which is particularly advantageous when turning cast iron under fluctuating conditions. Maintenance is straightforward: replace the indexable insert rather than regrinding, keeping machine downtime to a minimum and streamlining tool management.

FAQ

Is this insert suitable for interrupted cuts in cast iron?
Yes. The SNMG120412 T5125 Tungaloy indexable turning insert features a tougher CVD‑coated carbide grade designed specifically for interrupted cutting in cast iron.

Can the SNMG120412 fit standard SNMG holders?
Compatibility is determined by form, clearance, tolerance, fastening, size and thickness; the SNMG120412 follows ISO SNMG geometry and is intended for use with standard SNMG external and internal holders.

What are the main dimensions of the insert?
The insert is 12 mm in size, 4.76 mm thick, with a 1.2 mm corner radius and a 90° included angle.

Is the insert reversible or does it offer multiple cutting edges?
Yes. The SNMG120412 is double‑sided, providing multiple indexable cutting edges to extend service life and reduce replacement frequency.

Which materials is the grade T5125 recommended for?
T5125 is a tougher, CVD‑coated carbide grade optimised for cast iron machining under interrupted cuts or less stable conditions.
