LNMX 120408 T9125 Wendeplatten - Tungaloy

Benefit from the proven combination of ISO-standard geometry, the T9125 wear-resistant grade and a robust carbide body for steady, repeatable turning performance; order the insert through Metav Werkzeuge or consult our specialists for application support.

LNMX120408 T9125 – ISO turning insert, rectangular form, 90° cutting angle, Tungaloy

The LNMX120408 T9125 is an ISO-standard rectangular indexable insert intended for external and internal turning, engineered to deliver stable cutting edge performance and consistent wear resistance in general turning applications.

• LNMX120408 ISO geometry, 90° cutting angle
• Tungaloy grade T9125 for wear resistance
• Carbide substrate, suitable for turning
• 0.8 mm corner radius, 4.76 mm thickness

Consistent cutting performance through optimised grade and substrate

The insert combines a carbide substrate with the T9125 Tungaloy grade to balance wear resistance and toughness for everyday turning tasks. This composition supports sustained cutting-edge integrity in interrupted and continuous cuts, reducing the frequency of index changes and enhancing process stability. By selecting a grade developed for turning, operators gain a predictable tool life and uniform surface finish without needing complex parameter adjustments.

Easy integration with ISO toolholders and predictable mounting

The ISO designation and rectangular form factor mean the insert fits a wide range of standard holders when form, clearance, tolerance class, attachment and thickness match. The 90° approach lends itself to versatile external and internal operations where axial and radial positioning matter. The insert thickness of 4.76 mm and the 0.8 mm corner radius ensure secure clamping and defined engagement geometry, helping maintain repeatable part dimensions and minimising set-up variance across batches.

Practical benefits for machining quality and shop efficiency

Choosing an insert with a stable cutting edge and balanced substrate results in fewer process interruptions and a more predictable finishing requirement. The combination of ISO geometry and a robust carbide body supports consistent chip formation and surface quality, which is especially beneficial in mixed-production environments. Reduced rework and consistent cycle times contribute to a measurable uplift in operational efficiency and part conformity.

Guidance on selecting the right chipbreaker and application fit

The insert is supplied in a standard geometry; chipbreaker and specific grade match should be selected according to the material, machining style and machine stability. For general turning, opt for a chip control and insert variant that complements the machine rigidity and feed range. Compatibility is determined by the holder form, clearance angle and tolerance class, so ensure the chosen holder matches the ISO LNMX footprint for safe and effective operation.

FAQ

What materials is this insert suited for?
The LNMX120408 T9125 insert, with its carbide substrate and T9125 grade, is intended for general turning; selection of chipbreaker and grade should match the specific workpiece material and machining condition.

How does the 0.8 mm corner radius affect performance?
A corner radius of 0.8 mm increases edge strength and workpiece finish stability; it balances cutting forces and is suitable for general turning where a compromise between edge robustness and surface finish is required.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the LNMX form, clearance angle, tolerance class, attachment method, size and thickness; ensure the holder is specified for LNMX120408 inserts and secure clamping of the 4.76 mm thick plate.
