DNMG110404 T9225 — ISO turning insert by Tungaloy, 55° lead angle

The DNMG110404 T9225 is an ISO rhombic indexable insert intended for turning operations, engineered as a CVD-coated carbide grade for robust, reliable cutting in varying engagement conditions

• Robust CVD-coated carbide grade T9225
• Double-sided chipbreaker for versatility
• Rhombic 11 size with 55° lead angle
• Cylindrical hole compatible with ISO holders

Consistent cutting performance for changing conditions

The combination of a CVD-coated surface and a carbide substrate gives a stable cutting edge that tolerates slight interruptions and variable chip loads. The T9225 grade is formulated for mid to heavy steel machining where occasional tough spots or interrupted cuts occur; this means fewer unexpected tool changes and a more predictable cycle time. By favouring a tougher grade over a highly wear-resistant but brittle option, the insert offers an improved margin against chipping during unstable cutting, which supports continuous productivity in mixed-production environments.

Geometry that supports precision and repeatability

A rhombic profile with an 11-size designation and a 55° lead angle provides a balanced contact geometry that reduces cutting forces while maintaining dimensional control. The 0.4 mm corner radius contributes to a consistent surface finish without sacrificing edge strength, and the 4.76 mm plate thickness increases rigidity in the clamped assembly. These geometric choices help deliver repeatable results on external and internal turning tasks, enabling stable tool life and predictable part tolerances in serial or single-piece manufacturing.

Simplified tool setup and wide holder compatibility

The insert follows ISO standards, so compatibility with holders depends on form, relief angle, tolerance class, fixing method, size and thickness; this standardisation eases tool selection and inventory management. The cylindrical hole and double-sided format allow economical indexing: two usable edges per side and a straightforward clamping scheme reduce downtime and spare-part complexity. Where process security and quick changeover matter, the standardised form and mounting give planners and operators clear guidance for matching insert, holder and machine dynamics.

Practical benefits for production planning

Selecting this grade reduces the number of specialised items required in a tooling cabinet, thanks to its universal orientation for a broad range of steels. The combination of T9225 robustness and the rhombic geometry supports both roughing and light finishing passes when parameters are adapted, which can shorten the time to first good part. In addition, the CVD coating improves resistance to built-up edge and thermal wear during sustained cuts, safeguarding machining quality across varying batch sizes.

FAQ

What materials is this insert optimised for?
The Tungaloy DNMG110404 T9225 insert is optimised for medium to heavy steel machining, offering toughness and stable chip formation for mixed cutting conditions.

Can the insert be indexed for multiple cutting edges?
Yes, the insert is double-sided with a central cylindrical hole, allowing indexing and economical use of several cutting edges before disposal.

Which holder types are compatible with this ISO insert?
Compatibility depends on matching the ISO form, relief angle, tolerance class, fastening and thickness; the DNMG110404 form fits standard ISO-compatible turning holders designed for rhombic inserts.

How does the CVD coating affect tool life and finish?
The CVD-coated carbide of grade T9225 enhances thermal and abrasive resistance, reducing built-up edge and helping to preserve edge integrity, which supports consistent surface finish over longer cycles.

Is this insert suited to interrupted cuts or unstable conditions?
Yes, the T9225 grade is formulated for tougher engagement and performs well where marginally interrupted cuts or variable loads occur; its toughness reduces chipping risk.
