• Rectangular plate, 4.76 mm thickness

Consistent cutting performance through tailored material and geometry

The LNMX120412 combines ISO‑standard form and a Tungaloy carbide grade to deliver predictable tool life and steadier process control in turning operations. The T9115 grade balances wear resistance and toughness, reducing the frequency of insert changes and downtime. With an indexable insert design and a defined corner radius, the insert supports stable cutting forces and improved surface quality, translating directly into higher productivity on batch and serial turning tasks.

Improved edge stability and chip behaviour for reliable finishing

A 1.2 mm corner radius provides a compromise between edge strength and fine finishing capability: it resists chipping under interrupted cuts while still enabling acceptable surface finishes on semi‑finishing passes. The insert’s geometry, in combination with the grade’s mechanical properties, promotes controlled chip formation and reduced edge degradation. Because the grade is tailored to turning applications, tool life is extended under typical feed and speed ranges, making the component suitable for mixed workshop workloads where repeatable results matter.

Clear mounting compatibility and standardised fit for fast tool changes

Compatibility with toolholders is defined by the insert’s shape, clearance angle, tolerance class, clamping method, size and thickness. The rectangular form and 0° clearance angle ensure a consistent seating in holders designed for ISO turning plates; tolerance conformity simplifies interchangeability and reduces set‑up time. When selecting holders and clamping hardware, match the plate dimensions and thickness to the toolholder’s specifications to secure the insert correctly and maintain the intended cutting geometry.

Practical selection advice to boost process reliability

Choose the required chipbreaker style and grade depending on workpiece material and the machining objective: aggressive chip control for continuous turning, or moderate chip formers for mixed or interrupted cuts. The LNMX120412’s construction suits a range of steels and common alloys; pairing the plate with a stable, rigid setup and correct cutting parameters yields measurable improvements in cycle consistency and component finish.

FAQ

What workpieces is this insert suited for?
The LNMX120412 T9115 indexable turning insert is designed for general turning tasks; its T9115 carbide grade offers a balance of wear resistance and toughness suitable for a wide range of steels and common alloys.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius increases edge stability and reduces chipping risk during interrupted cuts, while still permitting acceptable surface finishes for semi‑finishing and general turning operations.

Is the insert compatible with standard ISO holders?
Yes. The ISO‑standard geometry of the LNMX120412 ensures compatibility with holders that match the plate’s form, thickness and tolerance class; correct clamping and matching dimensions are essential for secure seating.

What does the T9115 designation mean for tool life?
The T9115 grade from Tungaloy emphasises wear resistance with sufficient toughness, which generally extends insert life under typical turning conditions and helps maintain consistent cutting performance.

Can the insert be used for internal turning as well as external turning?
Yes. The LNMX120412 is suitable for both external and internal turning applications where the insert geometry and holder arrangement permit proper chip flow and clearance.
