CNGG120404 GH110 indexable insert for turning — Tungaloy

CNGG120404 GH110 is an ISO-format rhombic indexable insert designed for a wide range of turning applications, combining a wear-resistant carbide grade with a secure clamping concept for efficient outer and internal turning.

• ISO-compliant rhombic insert
• GH110 carbide grade: wear and toughness
• Double-sided chipbreaker for turning
• Cylindrical hole for secure clamping

Increased productivity through balanced grade and edge stability

The GH110 grade from Tungaloy offers a balanced combination of wear resistance and toughness, optimised to complement the insert geometry and cutting-edge stability. This balance reduces the frequency of tool changes and interrupts, which directly improves cycle time and lowers unit machining cost. As an indexable insert in the ISO turning family, the plate supports predictable toollife and consistent surface finish, helping to maintain throughput under varying cutting conditions while allowing straightforward rotation or replacement when wear occurs.

Precise geometry for reliable machining results

The plate’s rhombic form with an 80° approach angle and a 0.4 mm corner radius provides a versatile cutting edge suitable for finishing and light roughing. A 0° clearance angle and a thickness of 4.76 mm ensure rigidity in the clamping seat, while the 12 mm nominal size matches standard ISO holders. The insert is double-sided, allowing reversible use of the cutting edges, and features a cylindrical hole for positive fastening in compatible tool holders. These geometric details translate into improved repeatability and a clear guideline for selecting compatible holders — form, clearance, tolerance class, fastening and size determine fit.

Application guidance and process security

Intended for turning, the insert works effectively for both external and internal operations when the correct chipbreaker and cutting parameters are chosen. The double-sided chipbreaker provides controlled chip formation under a range of conditions, lowering the risk of built-up edge and stabilising the cut. For optimal results, match the chipbreaker style and grade to workpiece material, machining type and assembly stiffness; this approach preserves the cutting edge and ensures consistent performance. If further technical data or tailored recommendations are required, Metav Werkzeuge’s consultants can advise on parameter settings and holder compatibility to secure process reliability.

FAQ

What turning tasks is this insert designed for?
The CNGG120404 GH110 Tungaloy indexable insert is designed for general turning tasks, covering both external and internal operations when the appropriate chipbreaker and cutting conditions are selected.

Which geometric features are most relevant for holder selection?
The insert’s rhombic shape, 80° approach angle, 0° clearance, 0.4 mm corner radius and 4.76 mm thickness are the primary dimensions to match the toolholder and ensure correct clamping and cutting geometry for the CNGG120404 GH110.

How is the insert secured in the toolholder?
Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the CNGG120404 GH110 uses a cylindrical hole for positive clamping in matching ISO holders.

Is the cutting edge reversible and how is chip control achieved?
The plate is double-sided, enabling use of both faces to extend service life, and the double-sided chipbreaker supports controlled chip formation across a range of turning conditions.

What does the GH110 grade mean for machining performance?
The GH110 carbide grade from Tungaloy provides a balance between wear resistance and toughness, which supports stable cutting-edge behaviour and consistent performance in varied turning applications.
