DNMG 150408 T9225 Turning insert – Tungaloy (CVD-coated carbide, 55°)

DNMG 150408 T9225 is a rhombic, double-sided turning insert for industrial turning operations, optimised for medium-to-heavy steel machining

• CVD-coated carbide grade T9225
• Universal grade for medium to heavy steel
• Rhombic 55° geometry with 0.8 mm corner radius
• Double-sided insert with cylindrical hole

Consistent cutting performance for demanding steel applications

The CVD-coated carbide T9225 grade is formulated as a robust, universal option where variable engagement or slight interruptions demand additional toughness. The coating improves resistance to flank wear while the substrate maintains edge strength, resulting in stable chip formation and predictable tool life during both external and internal turning. For shops aiming to reduce downtime, this combination supports reliable batch-to-batch performance and fewer unplanned insert changes.

Geometry and mounting that support precision and versatility

The rhombic 55° geometry with a 0.8 mm corner radius provides a balance between profile control and cutting edge strength. The insert's 0° relief angle and a thickness of 4.76 mm contribute to a stable clamping arrangement when used with a compatible holder or boring bar. The cylindrical hole enables secure fastening and ensures repeatable seating; being double-sided effectively doubles the number of usable cutting edges, which optimises cost per edge in production environments. Compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness.

Practical benefits for process reliability and tool economy

Select the appropriate chipbreaker and grade based on the workpiece material and machining stability: the universal character of this grade simplifies tooling inventories while offering strong performance across a wide range of steels. For interrupted cuts or variable engagement, the enhanced toughness reduces the risk of edge chipping, and the coated surface supports higher cutting speeds with sustained surface finish quality. Together, these attributes contribute to predictable tool life and efficient production cycles.

FAQ

What materials is this insert designed for?
The Tungaloy DNMG 150408 T9225 insert is designed primarily for medium to heavy steel machining; its universal T9225 grade offers toughness and wear resistance suited to these materials.

How does the insert’s geometry affect cutting performance?
The rhombic 55° geometry and 0.8 mm corner radius provide a compromise between profile accuracy and edge strength, enabling controlled finishes and improved resistance to chipping under varying engagement.

Is the insert compatible with all DNMG holders?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; ensure the holder matches these specifications for correct seating and secure clamping.

What advantages does the CVD coating provide?
The CVD-coated carbide surface increases resistance to flank wear and supports higher cutting parameters while the substrate maintains core toughness for interrupted cuts.

How many cutting edges are available per insert?
As a double-sided DNMG insert, the component provides multiple usable edges, which improves cost efficiency per cutting edge in production settings.
