CNMG 120404 T9225 Turning Insert for Turning — Tungaloy

The CNMG120404 T9225 is an ISO-standard indexable turning insert engineered for robust medium-to-heavy steel machining, offering a balance of toughness and wear resistance for varying engagement conditions.

• CVD-coated carbide for robust performance
• Universal grade T9225 for medium–heavy steel
• Double-sided chipbreaker for stable chips
• Rhombic CNMG form with 0.4 mm corner radius

Consistent machining performance for mixed engagement conditions

The CVD-coated carbide grade T9225 delivers a pragmatic balance between hardness and toughness, making the insert suitable for sustained turning cycles where cutting conditions vary. The double-sided chipbreaker stabilises chip formation under interrupted cuts and changing depths of cut, reducing the likelihood of edge chipping and unplanned downtime. Thanks to the coating, flank wear progresses more predictably, supporting process stability and lower tooling costs per finished component.

Geometry and fit that simplify holder selection and clamping

Designed to the ISO CNMG form, this rhombic insert presents a reliable geometry for common external and internal turning holders; compatibility depends on insert form, 0° relief angle, tolerance class, fastening and thickness. The 0.4 mm corner radius smooths transition at the cutting edge for improved surface finish while the 80° included angle supports stable cutting forces. The presence of a cylindrical hole facilitates secure clamping; checking these parameters against the chosen holder ensures repeatable positioning and accurate results.

Practical benefits in the workshop: economy and uptime

Being double-sided and readily indexable, the insert reduces per-edge cost and simplifies inventory management. The 4.76 mm thickness and robust carbide base contribute to good edge life in demanding operations, while the universal nature of the T9225 grade allows one stock item to serve multiple steel turning tasks. For purchasers seeking predictable performance, the combination of coated substrate and proven chip control supports higher machine utilisation and consistent component quality.

FAQ

What materials is this insert suitable for? The CNMG120404 T9225 insert is designed primarily for medium–heavy steel turning; the CVD-coated carbide and universal T9225 grade provide toughness for variable engagement and light interrupted cuts.

Which clamping systems fit this insert? Compatibility requires a holder for the CNMG rhombic form that matches the insert's form, 0° clearance angle, tolerance class, fastening method and thickness; the cylindrical hole supports standard clamping arrangements.

What are the key geometric specifications to check before purchase? Check size (12 mm), thickness (4.76 mm), corner radius (0.4 mm), included angle (80°) and the presence of a cylindrical hole to ensure correct fit with the selected holder.

Is the insert indexable and reversible? Yes, the turning insert is double-sided and indexable, allowing the use of multiple cutting edges to extend service life and improve cost efficiency.

How does the T9225 grade help in production? The T9225 grade combines wear resistance and toughness for robust, predictable performance in steel turning, helping to maintain surface finish and reduce unscheduled tool changes.
