SNGA 120412 LX21 Tungaloy turning insert — ISO-standard square insert, 90° geometry

SNGA 120412 LX21 is an ISO-standard square indexable insert designed for external and internal turning, offering a 0° clearance angle and a 1.2 mm corner radius for demanding machining tasks.

• ISO-standard square turning insert
• Tungaloy LX21 carbide grade
• 90° geometry for robust external turning
• 1.2 mm corner radius for increased edge strength

Consistent integration and predictable performance

The ISO-standard form of this indexable insert guarantees compatibility with a wide range of holders when the holder’s form, clearance angle, tolerance class, fastening method, size and thickness match the insert. The SNGA120412 designation specifies the ISO outline and makes tool selection straightforward in CNC tool libraries. With a 0° clearance angle and a square shape, the insert provides a stable reference in the toolholder, reducing chatter and enabling consistent cutting conditions across batch runs. This results in predictable process parameters and easier machining planning.

Material combination for long life and edge stability

Manufactured in carbide and graded LX21, this turning insert balances wear resistance, toughness and edge stability. The grade is adapted to conventional turning operations where a blend of abrasion and impact resistance is required; it complements the insert geometry to extend tool life without sacrificing surface finish. The 1.2 mm corner radius increases cutting edge strength, making the insert suitable for interrupted cuts or heavier depths of cut while maintaining dimensional accuracy and reducing edge chipping.

Practical mounting and system compatibility

The insert is supplied with a cylindrical hole for secure clamping and a plate thickness of 4.76 mm, ensuring a rigid fit in compatible ISO toolholders. System setup typically comprises the ISO insert, a matching external holder or boring bar, a support pad or clamping set and replacement fixing screws. This modular approach simplifies stocking and maintenance: replacement inserts can be fitted quickly during planned tool changes, limiting downtime and stabilising production flow.

Suitable applications and selection guidance

Primarily intended for turning operations, this square insert performs well in both external and internal turning tasks where robustness and repeatable results matter. Because this insert is supplied without a chipbreaker, selection of a suitable chip control geometry should be made according to the workpiece material, machining strategy and machine rigidity. When machining alloyed steels, aluminium alloys or cast components, pairing the insert geometry with the LX21 grade delivers an efficient compromise between productivity and component surface quality.

FAQ

What materials is this insert suitable for?
The SNGA120412 LX21 Tungaloy turning insert in LX21 carbide is formulated to cover a broad material range; selection of cutting data and, where necessary, a chip-control geometry should be matched to the specific workpiece material.

Is the SNGA120412 compatible with standard ISO toolholders?
Yes, the SNGA120412 follows ISO dimensions and is compatible with ISO holders when the holder’s form, clearance angle, tolerance class, fastening and thickness correspond to the insert specifications.

Does the insert include a chipbreaker?
This SNGA insert is supplied without a chipbreaker; chip control must be achieved via matching holder geometry or selecting an alternative insert grade/geometry for specific materials.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius increases edge strength and helps resist chipping during interrupted cuts or heavier engagement, supporting stable dimensions and longer life in demanding turning operations.

Which replacement parts are recommended for the system?
A complete turning system for this insert typically comprises the ISO indexable insert, a matching external holder or boring bar, a support pad or clamping set and replacement fixing screws; Metav Werkzeuge can advise on compatible components.
