DNMG 150412 T9225 turning insert — CVD-coated carbide, 1.2 mm corner radius (Tungaloy)

DNMG150412 T9225 is an ISO turning insert engineered for versatile external and internal turning in steel applications, offering a balanced mix of toughness and wear resistance for interrupted or variable cutting conditions

• ISO rhombic insert, 55° cutting geometry
• CVD-coated carbide grade T9225
• 1.2 mm corner radius for robust cuts
• Double-sided chipbreaker, with cylindrical hole

Stable performance for medium‑to‑heavy steel turning

The combination of a CVD-coated cemented carbide substrate and the T9225 grade provides a reliable balance between wear resistance and toughness, intended for medium to heavy steel machining. The coating reduces flank and crater wear during continuous operation, while the substrate toughness mitigates chipping under slightly interrupted cuts. This results in fewer unplanned tool changes and more consistent cycle times, improving process predictability and lowering overall machining cost per part. Compatibility with standard tooling systems follows ISO conventions, which supports seamless integration into existing turning setups.

Geometry that ensures repeatable part quality

The rhombic DNMG form with a 55° included angle and a 1.2 mm corner radius provides substantial edge strength for roughing and semi‑finishing passes. The insert’s 4.76 mm thickness and cylindrical hole ensure secure clamping in the pocket, reducing vibration and improving surface integrity. The double‑sided chipbreaker gives two usable cutting positions, extending the serviceable life of each indexable insert. In practice, the geometry translates into stable cutting forces and more predictable surface finish, particularly when machining steels where rigidity and tool support are decisive for repeatability.

Operational efficiency, mounting and grade selection

Using an ISO indexable insert like this one enables rapid edge changes and straightforward inventory management. The DNMG150412 is designed to work with compatible external holders or boring bars; the fit is determined by form, clearance angle, tolerance class, attachment method, size and thickness. Selecting the double‑sided chipbreaker and the T9225 grade is advisable where variable engagement or occasional interruptions occur, as the grade adds toughness without sacrificing wear resistance. For application advice on feeds, speeds or holder pairing, guidance is available to match the insert to machining dynamics and stability, ensuring longer tool life and higher productivity.

FAQ

What materials is this insert suited for?
The DNMG150412 T9225 insert is specified for medium to heavy steel machining; the T9225 grade combines wear resistance and toughness for varying engagement conditions.

How is the insert mounted and secured?
Mounting is via the central cylindrical hole into a compatible holder or boring bar; correct fit depends on form, clearance angle, tolerance class, attachment and plate thickness.

How many usable edges are available per insert?
The insert features a double‑sided chipbreaker, allowing two indexable cutting positions before replacement is required.

What benefits does the CVD coating provide?
A CVD-coated surface improves resistance to abrasive and thermal wear, extending tool life and stabilising cutting performance in steel turning.

Which factors determine optimal grade and chipbreaker selection?
Choice depends on workpiece material, machining stability and the nature of the cut (continuous or interrupted); the T9225 grade is recommended for robust, variable conditions.
