CNMG 120408 T9225 — Tungaloy turning insert (ISO rhombic)

CNMG120408 T9225: an ISO-standard turning insert designed for mid-to-heavy steel machining with a CVD-coated carbide grade.

• ISO rhombic insert CNMG120408 T9225
• CVD-coated carbide for mid-to-heavy steel
• Double-sided chipbreaker, hole with cylindrical seat
• 0.8 mm corner radius and 0° relief angle

Long-lasting grade for variable cutting conditions

The T9225 grade is a CVD-coated carbide developed for robust, universal performance in mid-to-heavy steel turning. The coating process produces a hard, wear-resistant surface while the carbide substrate provides the toughness required for interrupted cuts or changing engagement conditions. This combination reduces flank wear and extends edge life, translating into fewer indexings and lower tool-change frequency without sacrificing productivity.

Geometry engineered for stability and surface quality

The rhombic CNMG form with an 80° included angle and corner radius 0.8 mm provides a stable cutting edge that balances strength and surface finish. The 0° relief angle supports positive cutting with predictable chip formation, while the double-sided chipbreaker aids chip control and cooling during continuous and semi-interrupted turning. The presence of a cylindrical hole ensures secure clamping in compatible holders, improving repeatability and reducing vibration at the tool–workpiece interface.

Practical system guidance and machining benefits

As an ISO-standard insert, compatibility depends on holder form, clearance, tolerance class, fastening method, size and thickness; the insert is best used with a matching external holder or boring bar and appropriate clamping hardware. Selecting the correct chipbreaker and the T9225 grade enables reliable performance when machining alloyed and carbon steels under variable conditions. The combination of a tough substrate and CVD coating provides improved wear resistance and fracture toughness, making the insert suitable for shops seeking a balance between economy and process stability.

FAQ

What materials is this insert suitable for?
The Tungaloy CNMG120408 T9225 insert is intended primarily for mid-to-heavy machining of steel and alloyed steels; the CVD-coated carbide substrate offers wear resistance and toughness for such applications.

How does the T9225 grade perform with interrupted cuts?
T9225 combines a tough carbide substrate with a CVD coating to increase fracture resistance under interrupted or varying engagement conditions, improving edge stability during turning operations.

Which holder features are required for secure clamping?
A compatible ISO external holder or boring bar with the correct pocket geometry, tolerance class and fastening for CNMG-size inserts is required; the cylindrical hole supports positive seating and repeatable clamping.

Can this insert be indexed to use both sides?
Yes, the rhombic CNMG geometry with a double-sided chipbreaker allows indexing to present fresh cutting edges, enabling economical use of the insert.
