FNMG110408 T9225 Tungaloy — ISO turning insert, CVD-coated carbide, 0.8 mm radius

The FNMG110408 T9225 is an ISO-standard rhombic turning insert designed for external and internal turning applications, offering a robust universal grade for medium-to-heavy steel machining

• CVD-coated carbide grade T9225
• Designed for medium-to-heavy steel turning
• Rhombic FNMG geometry, 0.8 mm radius
• Double-sided chipbreaker with cylindrical hole

Stable performance for medium-to-heavy steel turning

The FNMG geometry combined with the CVD-coated carbide of grade T9225 is optimised for stable cutting when conditions vary or intermittent cuts occur. The CVD layer provides a wear-resistant outer surface while the substrate delivers fracture resistance, so the insert balances tool life and toughness in demanding operations. For shops seeking predictable cycle times, this specification reduces unscheduled tool changes and supports steady production. The design is suitable for both external profiles and internal bore finishes, ensuring consistent results across typical turning tasks.

Geometry and mounting that support process reliability

The rhombic FNMG shape with a 0.8 mm corner radius and a 50° approach angle offers a compromise between strength and versatility; smaller radii aid fine finishing, while the geometry maintains edge support during heavier cuts. The insert is supplied with a cylindrical hole and a plate thickness of 4.76 mm, so compatibility with the toolholder is determined by form, clearance angle, tolerance class, fastening and size. The clearance angle of 0° here refers to the nominal relief geometry of the insert; correct holder selection and clamping ensure repeatable contact, optimal chip flow and reduced vibration for improved surface quality.

Effective chip control and economical indexing

Equipped with a double-sided chipbreaker, the insert permits both indexing options and economical use of cutting edges, lowering the cost per effective cutting edge. The chipbreaker pattern is chosen to match the material and stability of the setup: it promotes short, manageable chips in steel machining and supports thermal stability at common cutting speeds. As an indexable solution, the insert allows rapid edge change without regrinding, which streamlines tool management and contributes to overall process efficiency in production environments.

Selection guidance and practical integration into the tool system

Compatibility within the ISO turning system requires attention to holder geometry and fastening; the insert’s dimensions — FNMG110408 format, plate size 11 mm and the specified thickness — must match the seat and clamping method of the external holder or boring bar. Choose the chipbreaker and grade that correspond to workpiece material, machining strategy and machine-tool rigidity. If a combination of interrupted cuts and varying engagement is expected, the T9225 grade offers enhanced toughness suited to such mixed conditions while maintaining good wear resistance for longer tool life.

FAQ

What materials is this insert recommended for?
The FNMG110408 in grade T9225 is recommended primarily for medium-to-heavy steel turning, offering a balance of toughness and wear resistance suited to variable engagement and mildly interrupted cuts.

How does the CVD coating affect performance?
A CVD coating on the carbide substrate increases surface wear resistance while retaining core toughness; in the FNMG110408 it helps extend edge life under typical turning speeds for steel.

Is the insert compatible with standard FNMG toolholders?
Compatibility depends on holder seat form, tolerance class, clamping and plate thickness; the FNMG110408 follows ISO dimensions, so it fits standard FNMG holders when the seat and fastening match the listed measurements.

How many usable edges does the insert offer?
The double-sided design provides multiple indexable cutting edges per insert, reducing cost per edge compared with single-sided inserts and enabling fast edge changes in production workflows.

What should be considered when choosing the chipbreaker?
Select a chipbreaker that matches the workpiece material, machining type and machine stability; the double-sided breaker on this insert is intended to promote short, controllable chips for steel applications.
