CNGN120420 FX105 CNGN Turning Insert — Tungaloy, ISO turning insert

A CNGN120420 FX105 indexable turning insert engineered for precision external and internal turning, compatible with ISO-standard toolholders for robust, repeatable machining.

• FX105 grade for balanced wear resistance
• Carbide substrate for stable cutting edges
• ISO CNGN 120420 dimensional compatibility
• Rhombic plate, 12 mm size with R2 corner radius

Consistent chip control and extended tool life through balanced grade selection

The FX105 grade is formulated to balance wear resistance and toughness, delivering reliable edge stability under varying turning conditions. Manufactured on a carbide substrate, the plate maintains cutting integrity where intermittent cuts or variable feed rates occur. This balance reduces the frequency of tool changes and helps maintain consistent part quality; the combination of grade and geometry is especially beneficial for operations that require a compromise between long tool life and resistance to edge chipping. The result is fewer interruptions to production and a steady surface finish across batches.

Clear ISO compatibility reduces setup uncertainty and downtime

As an ISO-series insert, dimensional conformity is a central benefit: ISO-standard geometry and form allow predictable interaction with matched holders and boring bars. Compatibility depends on form, clearance angle (0°), tolerance class, fastening and plate thickness; specifying the correct holder and clamping set ensures secure seating and repeatable positioning. Where tool repeatability is vital, this standardisation shortens setup time, simplifies inventory of spare plates and supports rapid replacement, thereby improving process reliability on multi-shift shop floors.

Geometry tailored for adaptable turning tasks and surface quality control

The rhombic plate form with an included angle of 80° and a corner radius of 2 mm (R2) offers a practical compromise between strength and finish. The rhombic shape permits versatile orientation for both external and internal turning, while the R2 radius supplies enough edge strength for moderate depths of cut without sacrificing surface quality. Plate thickness of 4.76 mm supports stable clamping and resistance to bending under load. Together, these geometrical features help achieve consistent dimensional accuracy and predictable tool behaviour across a wide range of steel and alloy turning applications.

Practical recommendations for integration and application scope

Intended for turning applications, the indexable plate forms part of a system comprising the ISO insert, a suitable external holder or boring bar, a support shim or clamp set and replacement screws. The CNGN120420 FX105 is supplied without a central hole and without an integrated chipbreaker, so selection of an appropriate holder and chip control strategy is important for optimised performance. For best results, match the FX105 grade to the workpiece material and machining strategy; ensure the clamping torque and tolerance class of the holder align with the ISO dimensions to secure cutting stability and minimise vibration.

FAQ

What materials is this insert intended for?
The CNGN120420 FX105 insert from Tungaloy is designed for general turning tasks; the FX105 grade offers a balance of wear resistance and toughness suitable for a wide range of steels and alloyed materials.

How is the insert secured in the holder?
As an ISO-series plate, the CNGN120420 requires a compatible external holder or boring bar with matching form, clamp set and screw size; correct clamping and tolerance class are essential for repeatable seating and stable cutting.

Does the insert include a chipbreaker or mounting hole?
This Tungaloy insert is supplied without a chipbreaker and without a central mounting hole; chip control must therefore be managed via holder geometry and cutting parameters.

Which SKU and article number should be referenced when ordering?
Please reference SKU 6801895-Tungaloy or manufacturer article number 6801895 when enquiring about the CNGN120420 FX105 indexable turning insert.
