CNGG120408 GH110 indexable insert for turning by Tungaloy — rhombic, 12 mm, with cylindrical hole

The CNGG120408 GH110 is an ISO‑standard rhombic indexable insert designed for general external and internal turning, offering robust edge stability and straightforward interchangeability with matching holders.

• ISO-standard CNGG insert, 12 mm size
• GH110 Tungaloy grade for wear resistance
• Rhombic shape with 0° clearance angle
• Cylindrical through-hole and 0.8 mm corner radius

Engineered for dependable turning performance

The insert is built on a carbide substrate combined with the GH110 Tungaloy grade, providing a balance of wear resistance and edge toughness that translates into longer service life and stable surface finishes. In practice, this means fewer interruptions for regrinding or replacement and more predictable process control on the shop floor. The rhombic geometry and precise ground faces deliver consistent contact with the clamping system, which helps maintain repeatable cutting conditions and reduces variation between parts.

Designed for secure mounting and system compatibility

Manufactured to ISO dimensions, the insert’s form, clearance angle and tolerance class ensure compatibility with widely used external holders and boring bars. The presence of a cylindrical through-hole simplifies positive locating and clamping, while the specified 4.76 mm thickness and 12 mm size keep the insert stable under moderate cutting forces. Clear mechanical interfaces reduce set‑up time and enable rapid index changes, which is particularly valuable in mixed‑batch production where tool changes must be fast and reliable.

Practical selection for varied turning tasks

Equipped with a double-sided chipbreaker, the insert suits a range of turning operations; selecting the appropriate chipbreaker and the GH110 grade according to workpiece material and machining conditions optimises results. The geometry is appropriate for both external and internal turning cycles where a controlled chip flow and edge stability are required. For operators assessing options, the insert’s balanced properties make it a pragmatic choice where a combination of surface quality and tool life is sought.

Shop-floor benefits and handling

As an indexable solution, the insert contributes to efficient tool management and predictable downtime planning. The 0.8 mm corner radius offers a compromise between edge strength and achievable surface finish, while the standardised ISO form simplifies inventory and reduces the assortment of holders required. System assembly typically comprises the insert, a compatible outer holder or boring bar, a clamp plate or clamp set and replacement screws, enabling straightforward maintenance and quick turnarounds during production shifts.

FAQ

What operations is this insert suitable for? The CNGG120408 GH110 Tungaloy indexable insert (SKU: 6801879-Tungaloy) is intended primarily for external and internal turning where a balance of wear resistance and edge stability is required.

How does the GH110 grade affect tool life? The GH110 Tungaloy grade provides improved wear resistance and reliable edge behaviour, so the CNGG120408 insert typically yields longer effective cutting life compared with less wear‑resistant grades.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the insert’s ISO dimensions allow fitting to standard holders and boring bars designed for CNGG‑style inserts.

Can this insert be used for interrupted cuts? The carbide substrate and GH110 grade of the CNGG120408 insert offer a compromise of toughness and wear resistance that can handle light to moderate interrupted cuts if the overall machining set‑up provides sufficient rigidity.

What is the advantage of the cylindrical through‑hole? The cylindrical through‑hole in the CNGG120408 insert enables positive locating and stable clamping, which improves repeatability and helps maintain consistent cutting geometry across tool changes.
