SNGA120412 LX11 – Indexable turning insert, square 12, for turning by Tungaloy

The SNGA120412 LX11 is an ISO-format indexable turning insert intended for general external and internal turning operations, combining a balanced carbide grade with a robust 90° geometry for predictable machining results.

• LX11 grade for increased wear resistance
• Square 12 size with 90° cutting geometry
• 1.2 mm corner radius for stable cutting edge
• Carbide construction for robust tool life

Consistent productivity through balanced grade and edge stability

The combination of the LX11 cutting grade and a carbide substrate delivers a practical balance of wear resistance and toughness that supports steady machining cycles. This balance reduces unscheduled index changes and contributes to predictable tool life, which in turn helps maintain process stability on series turning operations. The insert’s design focuses on economic performance: longer abrasion intervals and a stable cutting edge reduce downtime and allow production planning with fewer interruptions. The Tungaloy grade integrates modern substrate technology to maintain edge integrity under mixed cutting conditions.

Secure mounting and ISO compatibility for straightforward retrofitting

As an ISO-standardised indexable insert, the geometry, rake angle (0°), tolerance class, fixings, size and thickness govern compatibility with the matching holder. The square 12 format and the cylindrical hole permit positive location and clamping with standard screw or clamp systems; the 4.76 mm plate thickness supports robust seating and repeatable positioning. These characteristics make the insert easy to replace in existing tool assemblies and minimise the need for adapter tooling, leading to faster tool changes and maintained concentricity in external and internal turning setups.

Geometry engineered for surface quality and edge security

The 90° included angle and 1.2 mm corner radius are tuned to provide a secure cutting edge and predictable cutting forces, which helps to achieve consistent surface finish on turned components. The insert is supplied without a chipbreaker, making it suitable where straight-chip evacuation or specific chip shaping strategies are required; pairing the insert with an appropriate chip control geometry and cutting data will optimise chip behaviour and reduce secondary operations. The square shape also allows multiple index positions per insert, improving cost-efficiency across larger batch runs.

Application guidance and quick integration into production

Designed for turning, the insert performs well in general external and internal turning when matched with the correct holder and cutting parameters. The carbide body tolerates a range of stable cutting conditions; however, selecting cutting speeds, feeds and coolant strategies that match the workpiece material and surface finish target is essential for best results. For applications where chip control or specialised surface integrity is required, consider selecting a complementary chipbreaker style or alternative grade. If technical data or parameter support is required, Metav Werkzeuge provides consultancy to align the insert choice with the machining task.

FAQ

What applications suit this insert best?
The insert is intended for general external and internal turning; SNGA120412 LX11 performs reliably in standard turning operations when paired with the correct holder and cutting data.

How does the LX11 grade affect performance?
The LX11 grade provides a balance of wear resistance and toughness, meaning the insert maintains edge stability under mixed cutting conditions and supports predictable tool life.

Is the insert compatible with existing ISO toolholders?
Yes. The insert follows ISO geometry conventions; compatibility depends on holder form, rake angle (0°), tolerance class, clamping method, size and thickness.

How many index positions does the square format provide?
The square plate offers multiple index positions, enabling economical use of the cutting edges before replacement is required.

Does the insert include a chipbreaker?
This variant is supplied without a chipbreaker; chip control should therefore be managed through holder geometry and cutting parameters or by selecting an alternative insert with an integrated chipbreaker.
