CNMA120408 FX105 Turning Insert – Tungaloy (ISO rhombic 80°; with cylindrical hole)

CNMA120408 FX105 is an ISO‑standard indexable insert designed for general turning applications, offering a blend of wear resistance and edge stability for productive machining.

• ISO‑standard rhombic insert, 80° geometry
• FX105 carbide grade for mixed wear and toughness
• Cylindrical hole for secure clamping
• Corner radius 0.8 mm for finish and strength

Predictable ISO‑compatible geometry for stable turning

The ISO‑standard rhombic form with an 80° geometry ensures compatibility with a wide range of external and internal turning holders. The indexable design supports quick corner changes and predictable seating; compatibility with a given holder is determined by form, clearance, tolerance class, fastening method, nominal size and 4.76 mm thickness. This layout reduces machine downtime by simplifying insert replacement and helps maintain consistent part geometry across production runs.

Balanced FX105 grade and carbide body for durable cutting

The Tungaloy FX105 grade fuses wear resistance with toughness to extend tool life under mixed cutting conditions. Manufactured in carbide, the insert maintains cutting‑edge stability during interrupted cuts and medium‑to‑high material removal rates. Because the insert is supplied without a chipbreaker, process planners can choose appropriate cutting data and holder geometries to manage chip flow; the absence of an integrally formed chipbreaker can be an advantage when custom chip control is achieved at the toolholder level or when machining longer, continuous chips is acceptable.

Secure clamping and machining benefits for finishing and roughing

A cylindrical hole and matching clamping hardware offer reliable seat and repeatability when combined with a suitable clamping set and underlay. The corner radius 0.8 mm supports improved surface finish and reduces stress concentration at the cutting edge, while the 0° clearance geometry is part of the ISO configuration that influences cutter engagement and tool presentation. The insert’s 12 mm nominal size and 4.76 mm thickness provide mechanical stability for a range of turning tasks; selecting the correct holder and machining parameters yields both consistent finishes and economical tool consumption.

FAQ

What turning tasks is this insert best suited for?
The CNMA120408 FX105 insert is intended for general external and internal turning where a balance of wear resistance and edge stability is required; it performs well in medium cutting conditions when combined with an appropriate holder.

What does the FX105 grade mean for cutting performance?
FX105 is a Tungaloy carbide grade developed to provide a compromise between wear resistance and toughness, giving consistent edge life in mixed material and interrupted cutting scenarios.

Is there a chipbreaker on this insert?
No; the item is supplied without a chipbreaker, so chip control is achieved via holder geometry, cutting parameters or separate chip‑control solutions rather than an integrated breaker.

How is the insert secured in the toolholder?
Retention is by a central cylindrical hole using a suitable clamping set and underlay; correct mating between insert and holder (form, size, thickness and tolerance) ensures repeatable seating.

Can this insert be used for finishing operations?
Yes; the 0.8 mm corner radius supports enhanced surface finish and edge strength, making the insert suitable for light finishing cuts when set up with appropriate feeds and speeds.
