• Double-sided chipbreaker configuration
• 0° clearance angle with cylindrical hole
• Corner radius 0.8 mm, thickness 4.76 mm

Reliable performance for medium to heavy steel turning

The CNMG120408 T9225 insert is a CVD-coated carbide grade engineered for robust, universal performance in demanding turning operations. The T9225 grade combines increased toughness with good wear resistance, which helps maintain cutting-edge integrity under variable engagement and slightly interrupted cuts. As a result, the indexable insert delivers stable chip formation, predictable tool life and consistent surface finish in serial production. The CVD coating improves abrasion resistance and reduces built-up edge, translating into fewer tool changes and higher throughput on the shop floor.

Interchangeability and secure mounting for fast handling

Constructed to the ISO CNMG format, the insert affords straightforward interchangeability across standard holders. Compatibility with a given toolholder is determined by form, relief angle, tolerance class, fastening method, size and thickness; this insert’s 0° clearance and cylindrical hole enable secure clamping and easy indexing. The double-sided configuration provides two usable cutting edges per side, enabling quick rotation and extended life between tool changes. For production environments this means shorter downtime during regrinds or exchanges and improved process repeatability when the correct holder and clamping set are used.

Geometry and grade for controlled cutting and surface finish

The 80° rhombic geometry offers a balanced compromise between cutting strength and accessibility for both external and internal turning. The corner radius 0.8 mm contributes to edge strength and helps achieve a robust surface finish without excessive cutting forces, while the plate thickness 4.76 mm increases rigidity for heavier cuts. The integrated double-sided chipbreaker is suited for medium to heavy depth-of-cut ranges and helps control swarf for safer chip evacuation. Select the chipbreaker and grade combination according to material, cutting mode and machine stability to gain the best combination of tool life and productivity.

FAQ

Is this insert suitable for interrupted cuts in steel?
The CNMG120408 T9225 insert is designed as a robust universal grade for medium to heavy steel turning and offers the toughness required for slightly interrupted cuts when the T9225 grade and appropriate chipbreaker are selected.

How many cutting edges are available per insert?
This rhombic, double-sided insert provides multiple usable edges thanks to its double-sided chipbreaker and indexable design, allowing rotation to fresh edges for extended service life.

What makes the T9225 grade appropriate for general steel machining?
The T9225 CVD-coated carbide balances toughness and wear resistance, providing stable chip formation and reliable cutting performance across a broad range of steel alloys and variable engagement conditions.

Can the insert be used for internal and external turning operations?
Yes; the 80° rhombic geometry offers versatility for both external and internal turning tasks, provided the correct holder and cutter overhang are applied to maintain rigidity.
