CNMN 120412 FX105 turning insert (ISO rhombic, 12 mm) by Tungaloy — 0° relief, 1.2 mm nose radius

CNMN 120412 FX105 is an ISO-standard indexable turning insert for general external and internal turning operations, designed to match holders by form, relief angle, tolerance class, fastening, size and thickness.

• ISO rhombic insert CNMN 120412 FX105
• 1.2 mm nose radius for precise profiles
• 0° relief for robust cutting
• Cemented carbide body, thickness 4.76 mm

Predictable compatibility and reliable clamping for workshop workflows

The ISO designation and standardised geometry ensure straightforward integration into recognised holder systems; ISO conformity reduces setup uncertainty and supports reproducible results across shifts. The insert’s rhombic form and specified thickness mean that clamping behaviour is predictable, which translates into fewer micro-adjustments at the machine and less downtime. For production planning, this stability simplifies tooling lists and minimises the need for multiple corrective test cuts.

Balanced cutting performance from the FX105 carbide grade

The FX105 grade combines wear resistance, toughness and edge stability to complement the chosen geometry; this balance is intended to maintain cutting-edge integrity over longer tool life while avoiding brittle failure. In practical terms, the cemented carbide construction gives a good compromise between life and versatility, making the insert suitable for a broad range of turning tasks when the correct chipformer and grade are selected. This results-focused combination helps to lower overall machining costs by reducing insert change frequency and improving process repeatability.

Practical geometry for accurate profiles and simplified tool management

A 1.2 mm nose radius delivers defined part contours while retaining sufficient edge strength for semi-finishing and profiling. The 0° relief supports robust engagement in many turning set-ups and the 12 mm size provides a familiar reference for pocketing and holder selection. As an ISO indexable solution, the system approach — insert, holder, clamp and screw — streamlines spare-part handling and inventory. For questions on matching holders or adapting cutting data, technical guidance is available to ensure the insert is used in the most productive way.

FAQ

What determines whether this insert fits a given holder?
Compatibility is defined by form, relief angle, tolerance class, fastening, size and thickness; the ISO designation helps match inserts to compatible holders.

Which turning operations are intended for this grade?
The FX105 grade and rhombic geometry are intended for both external and internal turning; selection of a suitable chipformer and cutting data depends on part material and stability of the set-up.

Is the insert suitable for interrupted cuts?
The grade’s balance of wear resistance and edge stability supports demanding conditions, making it appropriate for many interrupted-cut scenarios when used with a suitable toolholder and parameters.

Does this insert have a central hole for screw fastening?
This variant is specified as without hole, so it is clamped in holders designed for holeless rhombic inserts.

How does the 1.2 mm nose radius affect surface finish and strength?
A 1.2 mm radius offers a compromise between detail definition and edge strength, producing reliable profiles while maintaining resistance to edge chipping.
