CNGG 120408 GH110 – Tungaloy indexable insert for turning

The CNGG 120408 GH110 is an ISO-standard indexable insert designed for external and internal turning, offering a balanced combination of wear resistance and edge stability for general turning tasks.

• ISO-standard rhombic insert CNGG 120408
• GH110 Tungaloy grade for wear resistance
• Double-sided chipbreaker for versatile cutting
• Cylindrical hole and 0° clearance for stability

Stable cutting performance through optimised grade and substrate

The insert is produced in cemented carbide with the manufacturer’s GH110 grade, delivering a deliberate balance between hardness and toughness that supports consistent performance under varying cutting conditions. This material choice reduces flank wear and helps preserve the cutting edge across extended tool life, which translates into fewer indexings and reduced process interruptions. The combination of rhomboid geometry and the selected substrate promotes predictable chip formation and helps to maintain surface finish without frequent regrinding. Where cycle time and repeatability matter, the indexable insert offers measurable gains in productivity and process stability.

ISO compatibility for straightforward holder integration

As an ISO-specification insert, compatibility with a suitable toolholder depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness. The standardised dimensions simplify holder selection and spare-part logistics across production cells. The rhombic shape and a cylindrical central hole enable reliable clamping in matched holders; the 0° clearance reduces the need for special seat geometries. Clear reference to the ISO code helps machining planners ensure correct seating and torque values for the clamping screw, thereby avoiding uncertain fits. This alignment reduces setup time and contributes to reproducible machining results.

Designed for repeatable chip control and operator confidence

The double-sided chipbreaker and the moderate nose radius work together to control chip formation and evacuation, which is especially useful in mixed-material turning tasks. The insert’s geometry supports consistent cutting forces and enhances edge stability when interrupted cuts or variable feeds are required. The CNGG 120408 accommodates a range of turning strategies — from light finishing passes to more aggressive semi-finishing — while the central cylindrical hole ensures secure mounting and minimal movement under load. For production lines seeking a dependable balance of surface quality and tool life, this insert provides a pragmatic, application-oriented solution.
