CNMM 250916 T9225 — ISO turning indexable insert for turning by Tungaloy, CVD-coated carbide, 80°

A CNMM 250916 T9225 indexable insert engineered for external and internal turning in medium-to-heavy steel applications, offering a balanced mix of toughness and wear resistance

• ISO-compatible rhombic insert, 80° approach
• CVD-coated carbide grade T9225 for durability
• 1.6 mm nose radius for robust edge strength
• Cylindrical hole for secure clamping

High-performance grade for variable and interrupted cutting

The T9225 grade is a CVD-coated cemented carbide developed as a robust universal solution for medium-to-heavy steel machining. Its composition prioritises toughness without sacrificing wear resistance, which makes it particularly suitable when cutting conditions vary or when slightly interrupted cuts occur. The coating increases surface hardness and thermal stability, while the carbide substrate maintains edge reliability; this combination reduces flank wear and contributes to predictable tool life in serial production.

Geometry and ISO compatibility simplify toolholder selection

The rhombic ISO geometry with an 80° approach angle and a 1.6 mm nose radius delivers a balance between strength and versatility. The insert’s 0° relief and standard 25 mm size mean compatibility is determined by form, relief angle, tolerance class, mounting method, size and thickness; these factors define whether the insert will seat correctly in a given external holder or boring bar. The presence of a cylindrical hole supports secure clamping in indexed systems and facilitates repeatable positioning during tool changes.

Stable chip control and efficient production flow

Equipped with the TUS chipbreaker, the insert promotes stable chip formation, which reduces the risk of tangling and shortens cycle times through consistent evacuation. That stability improves surface finish and lowers the frequency of unplanned stops for cleaning or chip management. For workshops aiming at predictable throughput and lower tool-change frequency, the combination of geometry and grade offers measurable productivity advantages while keeping handling straightforward during insert replacement.

FAQ

What materials is this insert best suited for?
The CNMM 250916 T9225 insert is designed primarily for medium-to-heavy steel machining; the T9225 grade and its CVD-coated carbide substrate provide toughness and wear resistance suitable for varying engagement conditions.

How does the chipbreaker influence machining?
The TUS chipbreaker on the CNMM 250916-TUS promotes stable chip formation and easier evacuation, improving surface finish and reducing interruption times during turning operations.

Which holder features are required for proper seating?
Proper seating requires a holder or boring bar matching the insert form, relief angle, tolerance class, mounting method, size and thickness—factors that determine ISO compatibility for the CNMM 250916 T9225.

Can this insert handle interrupted cuts?
Yes, the robust grade and carbide substrate of the CNMM 250916 T9225 are intended to tolerate slight interruptions in the cut while maintaining edge integrity.

Is the insert indexed and easy to replace during production?
The rhombic ISO design with a cylindrical hole enables secure clamping and repeatable indexing; replacement follows standard procedures for ISO turning indexable inserts such as the CNMM 250916 T9225
