SNGA120412 LX10 — Indexable turning insert, square 90° (r 1.2) by Tungaloy

A SNGA120412 LX10 indexable insert designed for ISO‑standard external and internal turning, offering a balance of wear resistance and edge stability for productive machining.

• ISO 120412 format for broad compatibility
• LX10 grade with enhanced wear resistance
• Square 90° insert with 1.2 mm corner radius
• Cemented carbide, 4.76 mm thickness

Stable cutting performance from a balanced grade and geometry

The LX10 grade is engineered to combine wear resistance with sufficient toughness, so the cutting edge maintains form under continuous turning loads. The carbide substrate provides thermal stability and wear protection, which translates directly into longer periods between index changes and fewer unplanned interruptions. As the insert is ISO‑configured, cutters and holders are standardised; this reduces setup time and supports predictable throughput in repetitive production runs. Confidence in feed‑and‑speed decisions is increased because the material and coating synergy is selected to support consistent tool life.

Faster changeovers and assured ISO compatibility

Compatibility to the toolholder is determined by shape, relief angle, tolerance class, fastening, size and thickness. The SNGA designation follows the ISO 120412 geometry, so replacement inserts can be specified and fitted without guessing. The indexable insert format and a centred cylindrical hole ensure positive clamping when used with the corresponding external holder or boring bar, which simplifies tool management and reduces machine downtime. Clear, standard dimensions mean spares can be stocked centrally for rapid access, improving overall process efficiency.

Robust edge and dimensional control for better surface finish

A corner radius of 1.2 mm combined with a square 90° profile gives a sturdy cutting edge that resists chipping in interrupted cuts and heavy cross‑section removals. The plate thickness of 4.76 mm increases rigidity in the clamped assembly, reducing vibration and supporting repeatable part geometry. These attributes help to maintain consistent surface quality and dimensional tolerance, translating to fewer reworks and higher first‑pass yield. Where stability and predictable form are critical, the geometry supports conservative to aggressive cutting strategies without compromising edge life.

Practical system assembly and selection guidance

An ISO indexable plate works as part of a system: the insert, a matching external holder or boring bar, a backing pad/clamp set and the correct fastening screws. The insert is supplied with a cylindrical hole and no integrated chipbreaker, so choice of holder and machining parameters should reflect the workpiece material and the required chip control. For unfamiliar applications or critical materials, technical consultation is recommended to select the most appropriate chipformer, feed rates and cooling strategy. Metav Werkzeuge can assist with holder matching and process optimisation to make the most of the Tungaloy grade.

FAQ

Is this insert suitable for both external and internal turning?
The SNGA120412 LX10 indexable insert is intended for ISO‑compatible external and internal turning; compatibility with a holder is determined by shape, relief angle, tolerance and fastening.

Which materials is the LX10 grade best suited to?
The LX10 grade from Tungaloy offers a balance of wear resistance and toughness for broad turning applications; for material‑specific recommendations, Metav Werkzeuge can advise on feeds, speeds and chip control.

How is the insert clamped in the toolholder?
The insert features a cylindrical hole and is secured in a matching external holder or boring bar with a backing pad/clamp set and screws, ensuring stable clamping and repeatable positioning.

What are the critical geometry values to consider for process planning?
Key values are the 90° square geometry, a 1.2 mm corner radius and a thickness of 4.76 mm; these influence cutting edge strength, surface finish and recommended machining parameters.

Does the insert include a chipbreaker?
This insert is supplied without a chipbreaker; chip control must be managed via holder choice, cutting parameters or the use of an alternative insert geometry.
