CNGA 120416 LX11 indexable insert for Turning by Tungaloy — LT chipbreaker, 80° rhombic

A CNGA120416-LT LX11 Tungaloy indexable turning insert designed for ISO-compliant external and internal turning, offering stable edge life and reliable chip formation for a wide range of steel and alloy applications

• ISO 80° rhombic form for robust turning
• LX11 carbide grade for wear-resistant edges
• Chipbreaker LT for consistent chip control
• 1.6 mm nose radius, 4.76 mm thickness

Reliable cutting performance for production turning

The insert delivers a balanced combination of edge stability and wear resistance thanks to the LX11 Tungaloy grade, engineered for turning applications. The rhombic 80° geometry provides good approach angles for both external and internal turning, while the chipbreaker LT promotes controlled chip formation, reducing the risk of entanglement and improving surface finish. These characteristics translate into fewer interruptions and a steadier machining cycle, supporting higher process reliability in batch and serial production.

Secure fit and simple mounting for consistent results

Compatibility with the toolholder is determined by form, relief angle, tolerance class, clamping and size; the insert features a 0° relief angle and a cylindrical hole for secure fastening. The standardised ISO designation ensures interchangeability with matched clamping sets and screw assemblies, simplifying inventory and changeover. The precise dimensions and fit reduce vibration and enable repeatable positioning, which contributes to consistent dimensional accuracy and repeatable surface quality.

Grade LX11 and carbide substrate explained

The Tungaloy LX11 grade combines abrasion resistance with sufficient toughness to withstand intermittent cutting conditions. In practice, the cemented carbide substrate resists flank wear while the coating and microstructure support edge integrity under varied cutting speeds. This makes the insert suitable for a broad spectrum of steels and alloyed materials where a balance between life and edge security is required. The result is predictable tool performance and lower overall tooling consumption when grading and geometry are matched to the workpiece.

Practical machining guidance and application scope

For best outcomes, pair the insert with a compatible external holder or boring bar and select the chipbreaker and grade to match workpiece material and stability. The 1.6 mm nose radius is a pragmatic choice for general-purpose turning, giving a good compromise between strength and surface finish. The insert is intended for turning operations where ISO-standard inserts are specified; select feed and cutting data according to material and machine rigidity to fully exploit the insert’s wear properties and chip control.

Why this insert supports operational efficiency

By combining a dedicated chipbreaker with an ISO rhombic form and a robust carbide grade, the insert reduces the need for frequent index changes and improves machining throughput. The standardised dimensions and the cylindrical mounting hole facilitate rapid exchange and straightforward tool management. In short, the design focuses on stable metal removal, reliable edge life and ease of integration into existing turning tool systems.
