CNGA 120408 FX105 indexable insert — turning, Tungaloy

A CNGA120408 FX105 indexable turning insert designed for reliable external and internal turning with ISO CNGA geometry.

• FX105 grade for wear resistance and toughness
• ISO CNGA rhombic form, 80° approach angle
• 0.8 mm corner radius for consistent finishes
• Suitable for external and internal turning

Consistent cutting performance for productive turning

The FX105 grade is a Tungaloy-developed cemented carbide that balances wear resistance and toughness, resulting in stable cutting edges under varied cutting conditions. Using this insert in turning operations reduces edge chipping and maintains dimensional accuracy over longer tool life, which in turn decreases machine downtime and improves batch-to-batch consistency. The absence of a dedicated chipbreaker means chip control depends on cutting parameters and workpiece material, so select feeds and speeds to match the desired chip form for efficient evacuation.

Precision geometry and secure clamping for repeatability

The ISO CNGA rhombic form with an 80° approach angle and a 0° relief angle gives a predictable cutting direction and good accessibility for profiling and shoulder work. The insert’s cylindrical hole enables positive location in holders that match the insert’s size, thickness (4.76 mm) and tolerance class. Correct matching of holder form, relief angle, tolerance and clamping components ensures repeatable seating and reduces vibration, which improves surface finish and extends tool life. The indexable insert format allows quick edge changes without regrinding, keeping production moving.

System benefits and application guidance for reliable results

As part of a system—insert, external holder or boring bar, shim/clamp set and spare screws—this grade supports a broad range of turning tasks. The balanced properties of FX105 make it suitable for many steels and alloyed materials where a compromise between tool life and edge stability is required. The 0.8 mm corner radius promotes surface integrity on interrupted cuts and shoulders while the rhombic form offers flexibility in orientation. For process optimisation, pair the insert with a rigid holder and adjust cutting data to the workpiece and machine capability to maximise productivity.

FAQ

What workpiece materials is this insert suitable for?
The CNGA120408 FX105 indexable insert (Tungaloy) is formulated for general turning and offers a balance of wear resistance and toughness suitable for many steels and alloyed materials; matching cutting data to the material is recommended.

How does the 0.8 mm corner radius affect surface finish?
A 0.8 mm corner radius on the CNGA120408 FX105 insert improves surface integrity on shoulders and interrupted cuts, promoting a smoother finish while maintaining edge strength.

Is a chipbreaker integrated in this insert?
This CNGA120408 FX105 insert is supplied without a chipbreaker; chip control depends on cutting parameters and workpiece selection, so adjust feed and speed accordingly.

What must be considered when choosing a holder for this insert?
Compatibility for the CNGA120408 FX105 depends on holder form, relief angle, tolerance class, clamping method, insert size and thickness; ensure the holder matches the ISO CNGA geometry and the 4.76 mm plate thickness.

Can this insert be used for internal turning?
Yes, the rhombic CNGA form and 80° approach angle make the CNGA120408 FX105 suitable for both external and internal turning operations when combined with the appropriate boring bar or holder.
