SNMA 120408 FX105 Tungaloy Turning Insert — ISO square turning insert for general turning

A SNMA120408 FX105 Tungaloy insert engineered for external and internal turning where ISO compatibility and predictable edge performance are essential

• ISO‑standard square insert 12 × 12 mm
• FX105 Tungaloy grade for wear and edge stability
• 0° rake with 0.8 mm corner radius

Dependable ISO compatibility for predictable tool cycles

The insert follows the ISO designation for a square turning format, ensuring straightforward interchangeability with standard holders. The nominal size of 12 mm and the plate thickness of 4.76 mm are part of an established system: the insert, a matched external holder or boring bar, a backing shim and a clamping set with replacement screws. The presence of a cylindrical hole and a central bore influences clamping geometry, so compatibility is determined by holder form, clearance angle, tolerance class, fixing method, size and thickness — all factors that contribute to repeatable set‑up and reduced machine downtime. This systematic approach reduces administrative complexity in tool inventory and supports consistent production flow.

Grade and geometry that extend service intervals

The Tungaloy FX105 grade combines wear resistance and toughness to provide edge stability under varied turning conditions. Manufactured from cemented carbide, the grade is intended to complement insert geometry with a balanced focus on resistance to abrasive wear and retention of a sharp cutting edge. The combination of a 0.8 mm corner radius and a 0° rake supports robust flank strength while enabling controlled cutting forces for many common turning tasks. In practice, this means longer intervals between indexings, more consistent surface finishes and fewer unexpected tool changes — advantages that translate directly to higher net productivity and lower process variability.

Operational benefits and recommended assembly for productivity

Designed for general turning, the insert is suitable for both external and internal operations when matched with the appropriate chip control and holder stability. Selecting a chipbreaker and grade aligned with the workpiece and machining strategy is essential: stable clamping and an optimised holder increase vibration resistance and allow the FX105 grade to deliver its intended durability. The square plate geometry provides four usable edges, and the central cylindrical hole aids secure clamping and repeatable seating. When integrated as part of a complete system — insert, holder, backing shim and clamping hardware — the configuration promotes faster index changes and consistent dimension control, supporting higher throughput and predictable component quality.

FAQ

What turning operations is this insert intended for?
The SNMA120408 FX105 Tungaloy insert is intended for external and internal turning where ISO‑standard inserts are specified, offering four usable edges and reliable seating via its cylindrical hole.

How does the FX105 grade affect tool life?
The FX105 Tungaloy grade provides a balance of wear resistance and toughness, which supports extended tool life and consistent edge stability during many turning applications.

Which holder characteristics must be considered for correct compatibility?
Compatibility requires matching holder form, relief angle (rake), tolerance class, fixing method, size and thickness; these determine correct seating and clamping of the insert.

What is the effect of the 0.8 mm corner radius in machining?
A 0.8 mm corner radius increases flank strength and improves surface finish stability under moderate cutting conditions while influencing permissible cutting depths and feed rates.

Is the insert supplied as a complete system?
The SNMA120408 FX105 is supplied as the insert itself; the complete system typically consists of the insert, a matched holder or boring bar, backing shim and clamping hardware selected to suit the application.
