SPGN 120308 LX11 turning insert by Tungaloy — ISO turning insert, square form, LX11 grade

SPGN120308 LX11 Tungaloy insert designed for ISO‑standard turning tasks; intended for external and internal turning where a robust carbide grade and stable cutting edge improve productivity

• ISO‑compliant SPGN geometry
• LX11 grade for improved wear resistance
• Square insert, 12 mm size
• 11° clearance angle for reliable cutting

Precision and holder compatibility for dependable turning

The indexable insert follows the ISO‑standard SPGN form, which simplifies selection and ensures fit with compatible holders. Thanks to clear specifications for form, 11° clearance angle and tolerance class, the insert mates predictably with a matching external holder or boring bar. For production environments this compatibility reduces setup time and helps maintain consistent part quality across batches.

Material grade and edge stability that extend tool life

Made from high‑performance carbide and specified as grade LX11, the cutting grade balances wear resistance and toughness to resist chipping on interrupted cuts. The specified 0.8 mm corner radius contributes to edge stability and distributes cutting forces, which reduces flank wear in routine turning operations and supports longer service intervals before index changes.

Design features that support process reliability

The square 3.18 mm thick insert in a 12 mm size delivers multiple effective cutting edges per index, promoting economical usage and quick edge changes. The insert is supplied without hole and without chipbreaker, so it is suited to setups where the holder provides clamping and chip control is managed by cutting parameters or additional tooling. This geometry is particularly effective for general turning tasks that prioritise consistent dimensional accuracy.

Typical uses and selecting the correct set‑up

Intended for turning, the insert is suited to both external and internal operations when matched with the correct holder, shim and clamping set. Choose the LX11 grade and the corner radius according to workpiece material and desired surface finish: a larger radius for higher stability and a small radius for fine finishing passes. The system approach—insert plus holder, shim and clamping screws—ensures replacement components are straightforward to source and fit.

FAQ

What materials is this insert suitable for?
The SPGN120308 LX11 insert is formulated for general turning and the LX11 grade provides a balance of wear resistance and toughness suitable across a broad range of materials; select grade and geometry to match specific workpiece alloys.

How does the square form affect cutting strategy?
A square form offers multiple cutting edges per index and good stability; the SPGN geometry with a 0.8 mm corner radius supports heavier cuts while allowing several re‑indexes for economical use.

Is a chipbreaker included with the insert?
This insert is supplied without a chipbreaker; chip control is achieved via holder selection and cutting parameters or by using a holder with integrated chip control.

What holder does the insert require?
Compatibility depends on the SPGN form, clearance angle, tolerance and thickness; pair the insert with an ISO‑compliant external holder or boring bar sized for SPGN120308 geometry.

How many indexes does the insert provide before replacement?
The square SPGN insert provides multiple cutting edges per index; the exact number of productive indexes depends on cutting conditions and workpiece material, with LX11 designed to extend edge life under typical turning loads.
