CNMA120412 FX105 rhombic turning insert by Tungaloy — ISO-standard insert for external and internal turning

CNMA120412 FX105 is a rhombic, ISO‑standard indexable turning insert designed for a wide range of turning tasks, offering a balanced combination of wear resistance and cutting-edge stability for demanding production environments.

• ISO rhombic insert for turning applications
• FX105 grade for improved wear resistance
• Carbide substrate for long tool life
• With cylindrical hole for secure clamping

Enhanced productivity through a balanced grade and hard substrate

The FX105 cutting grade, combined with a solid carbide body, provides an excellent compromise between wear resistance and edge strength, making it suitable for many common turning tasks. This grade is formulated to extend the time between index changes, reducing machine downtime and contributing to a smoother production flow. Specified as an ISO rhombic insert, it fits standard indexable holders when matched for form, clearance and size, simplifying tool inventory and enabling predictable process planning.

Reliable clamping and geometry for consistent results

The rhombic insert shape with a cylindrical hole and a nominal 1.2 mm corner radius promotes stable seating in compatible holders and helps to maintain a repeatable cutting edge position. The 0° clearance and 80° included angle support precise contact with the workpiece during both external and internal operations, which in turn enhances dimensional stability and surface finish. These geometric characteristics translate into fewer rejects and less rework for routine turning tasks.

Practical application guidance and material suitability

Intended for turning, the insert is delivered without a dedicated chipbreaker, allowing process engineers to select cutting parameters and holders that match specific workpiece materials and rigidity conditions. The carbide composition and FX105 grade make the insert particularly effective on a broad range of steels and alloyed materials where balanced toughness and wear resistance are required. For best results, pair the insert with a holder that matches the ISO form, thickness and tolerance class to ensure correct clamping and heat dissipation.

Integration into production and handling recommendations

As part of an ISO series system, the insert is compatible with standard toolholders when the holder’s form, clearance angle and size correspond to the insert’s specifications. Correct torqueing of the fastening screw and the use of the appropriate shim or clamp plate contribute to secure fixation and repeatable performance. When machining at elevated speeds, verify that the chosen cutting data and coolant strategy align with the insert’s characteristics to prolong edge life and stabilise chip formation.

FAQ

What holders are compatible with this insert?
The CNMA120412 FX105 insert fits holders designed for ISO rhombic inserts with matching form, thickness and tolerance class; secure the insert with the appropriate clamp or shim for repeatable seating.

Is the FX105 grade suitable for alloyed steel?
Yes, the FX105 Tungaloy grade is formulated to provide a balance of wear resistance and toughness that performs well on a wide range of steels and alloyed materials in turning operations.

Does the insert include a chipbreaker?
This insert is supplied without a chipbreaker, allowing selection of process parameters and holder design to control chip formation according to the specific material and operation.

What is the corner radius and how does it affect cutting?
The insert has a 1.2 mm corner radius; a larger radius improves surface finish and edge strength but requires more cutting force, so choose feeds accordingly to avoid overload.

Can the insert be used for internal turning?
Yes, the geometry and rhombic form permit both external and internal turning when used with a suitably rigid boring bar or internal holder.
