CNGA 120412 LX21 indexable insert for turning – Tungaloy

A CNGA120412 LX21 Tungaloy indexable insert designed for ISO‑standard external and internal turning tasks.

• ISO‑standard rhombic insert 80° geometry
• Tungaloy LX21 grade, wear‑resistant carbide
• Cylindrical hole for secure clamping
• 1.2 mm corner radius for versatile turning

Consistent cutting performance through balanced grade and geometry

The CNGA120412 LX21 indexable insert pairs a controlled geometry with a purpose‑engineered cutting material to deliver reliable results in general turning. The LX21 grade from Tungaloy provides a balanced combination of wear resistance and toughness, which supports cutting‑edge stability during interrupted cuts and medium‑duty operations. As an indexable insert, it reduces downtime for tool changes and enables predictable tool life when matched with the correct holder and clamping system.

Fast integration into ISO tool systems for predictable set‑ups

Designed to the ISO plate designation, the rhombic shape with an 80° approach angle gives secure tool engagement and controlled chip flow. The cylindrical hole and standard clamping interface permit straightforward mounting in compatible external holders or boring bars, while the 0° clearance angle and 1.2 mm corner radius offer a compromise between strength and finish. Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness, so selection within the ISO system ensures repeatable set‑ups and reduced setup time.

Practical use and system composition for efficient turning operations

The insert is intended for turning and forms part of a complete system: an ISO indexable plate, a matching external holder or boring bar, a backing plate/clamp set and the necessary replacement screws. With no integrated chipbreaker, the cutting edge is best combined with a holder and cutting parameters matched to the workpiece and machine rigidity. This arrangement allows a focus on throughput and surface quality while simplifying spare‑part management and stocking of standardised components.

Clear selection criteria and application advice for process assurance

When choosing the insert, consider workpiece material, feed and depth of cut together with machine and clamp stability; the LX21 grade favours a wide balance of applications where both wear resistance and edge integrity are required. For unfamiliar setups, verify holder geometry and tolerance class to confirm seat and screw compatibility. The structured approach reduces trial‑and‑error and supports reproducible machining results across batches.

FAQ

What turning operations is this insert suitable for? The CNGA120412 LX21 Tungaloy indexable insert is designed for external and internal turning operations and performs well in general turning tasks when combined with a compatible holder and clamping set.

How does the LX21 grade affect tool life and performance? The LX21 grade from Tungaloy balances wear resistance and toughness to maintain cutting‑edge stability under varying conditions, offering consistent performance for medium‑duty turning applications.

How can compatibility with a holder be confirmed? Compatibility is confirmed by matching the insert form, clearance angle, tolerance class, fastening method, size and thickness; verify these parameters against the holder specification and the CNGA120412 designation.

Does the insert include a chipbreaker? No, this insert is supplied without a chipbreaker; chip control should be managed via holder geometry, feeds and speeds appropriate for the application.

What components are required for a complete system setup? A complete setup typically requires the indexable plate, a matching external holder or boring bar, a backing plate/clamp set and appropriate replacement screws for secure assembly.
