CNMG090308 T9225 indexable insert for turning — Tungaloy

The CNMG090308 T9225 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering high toughness for variable engagement conditions.

• CVD-coated carbide for high wear resistance
• Robust T9225 grade for medium–heavy steel
• Rhombic CNMG format, 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole

High toughness and consistent cutting performance

The insert combines a CVD-coated carbide substrate with the T9225 grade to provide a balance of hardness and toughness suited to medium to heavy steel machining. The coating improves wear resistance and reduces crater wear, which extends edge life under varying engagement conditions. Thanks to the universal nature of the grade, performance remains stable when occasional interruptions or changing cut parameters occur, reducing unplanned stoppages and contributing to predictable production runs.

Better chip control and surface quality for productive turning

Equipped with a double-sided chipbreaker, this indexable insert promotes controlled chip formation and evacuation during both external and internal turning. Improved chip control lowers the risk of recutting, protects the toolholder, and supports improved surface finish on finished components. For production environments where consistent part quality and reduced post-process work are priorities, the chipformer design contributes directly to productivity and reduces the need for secondary finishing operations.

Compatibility and practical mounting guidance

Compatibility with toolholders depends on matching insert geometry: form, relief angle, tolerance class, fastening method, size and thickness. The rhombic shape and 0° relief angle deliver a strong cutting edge, while the 0.8 mm corner radius balances edge strength and surface integrity. The insert’s 3.18 mm thickness and CNMG size ensure interchangeability within ISO systems when the holder accepts CNMG090308 geometry. Use a suitable clamp, shim and replacement screws to secure the insert and maintain repeatable positioning.

Shop-floor benefits and selection advice

For many turning tasks the combination of grade and chipbreaker yields lower tool consumption and higher process stability, translating into a favourable cost-in-use. The universal characteristics of this insert help to simplify tooling inventories while still handling demanding steel turning. When machining unfamiliar alloys or when stability is limited, select the chipbreaker and cutting parameters to prioritise toughness. Metav Werkzeuge’s specialists can advise on optimal holder combinations and feeding strategies to match machining stability and part tolerance requirements.

FAQ

What applications is this insert suitable for?
The CNMG090308 T9225 insert is intended for external and internal turning operations, particularly where medium to heavy steel machining requires a robust, tough cutting edge.

Which materials can be machined with this grade?
The T9225 grade and CVD-coated carbide substrate are optimised for a broad range of steel applications, especially medium to heavy turning; selection of chipbreaker and parameters should match the specific alloy and stability.

What does the T9225 designation indicate?
T9225 denotes a universal, CVD-coated carbide grade engineered for toughness under interrupted cuts and varying engagement conditions, offering reliable edge life in demanding turning tasks.

How is the insert secured in the toolholder?
This insert features a cylindrical hole for screw clamping; it is double-sided and indexed, so the clamp, shim and replacement screws used in the ISO holder must match the insert’s form, size and thickness for secure, repeatable mounting.

How does the corner radius affect performance?
The 0.8 mm corner radius increases edge strength and is a compromise between toughness and surface finish, providing improved resistance to chipping during deeper cuts while still supporting good finished surface quality.
