Higher throughput thanks to reliable chip control

The combination of a CVD‑coated carbide substrate and the T9225 wear grade delivers stable cutting performance under varying engagement conditions. The double‑sided chipbreaker is engineered to channel chips consistently, reducing rework and downtime by promoting predictable chip formation. For workshops managing mixed batch sizes or lightly interrupted cuts, this translates into fewer tool changes and improved cycle times without sacrificing surface quality.

Predictable fit and repeatable accuracy with ISO compatibility

Built to ISO specifications, the rhombic CNMG geometry ensures interchangeability with compatible toolholders; compatibility depends on form, relief angle, tolerance class, fastening and thickness. The 80° included angle and 0° relief maintain contact stability during external and internal turning, which helps to preserve dimensional accuracy over longer production runs. Where tool changeover speed matters, the standardised design reduces assembly errors and supports consistent clamping behaviour.

Robust grade tailored to medium and heavy steel applications

The T9225 grade is a universal, tough CVD coating formulated for medium to heavy steel machining where occasional interruptions or variable engagement demand extra toughness. This balance between wear resistance and fracture resistance extends effective tool life on structural and alloy steels, allowing for more aggressive feed rates while mitigating edge chipping. Shops focusing on productivity benefit from fewer unexpected tool failures and steadier surface finishes.

Easy integration into existing tool systems and secure clamping

With a cylindrical locating hole and standard thickness, the insert integrates with common ISO holders and clamping kits. The rhombic profile and the 0.8 mm corner radius offer a compromise between strength and surface finish, while the double‑sided design enables economical indexing. For technical clarification or to confirm holder compatibility, our team can supply dimensional checks and mounting guidance to ensure immediate fitment without trial‑and‑error.

FAQ

What materials is this insert suitable for?
The CNMG120408 T9225 insert is designed primarily for medium to heavy steel machining; the T9225 grade gives additional toughness for variable engagement and lightly interrupted cuts.

Is the insert indexable and reversible?
Yes, the insert is double‑sided and indexable, allowing two cutting edges per side where appropriate; the locating hole supports secure clamping in standard ISO holders.

How does the T9225 coating affect performance?
The CVD‑coated T9225 provides a balance of wear resistance and toughness, improving edge life under mixed cutting conditions and supporting more stable chip control compared with uncoated grades.

Which holder features ensure compatibility with this insert?
Compatibility is achieved with holders that match the CNMG form, tolerance class, fastening method, size and thickness; the cylindrical locating hole assists precise positioning and secure fastening.

Can this insert be used for finishing operations?
With its 0.8 mm corner radius and rhombic geometry, the insert can achieve good surface finishes in many turning operations; selection of feed, speed and holder rigidity will determine final surface quality.
