DCMT 11T304 T9225 — CVD-coated carbide turning insert (Tungaloy)

The DCMT11T304 T9225 is an ISO-standard, rhombic turning insert designed for turning applications where variable engagement and interrupted cuts demand increased toughness and reliable chip control.

• CVD-coated carbide for durability
• Universal grade for medium–heavy steel
• Rhombic ISO shape, 55° cutting angle
• 0.4 mm corner radius for secure engagement

Consistent performance for medium to heavy steel turning

The insert uses a CVD-coated T9225 carbide grade engineered for robust performance in variable cutting conditions. This combination of coating and substrate provides improved wear resistance while retaining toughness where interrupted cuts or fluctuating depths of cut occur. The result is a predictable tool life under common shop-floor variations, reducing unexpected stoppages. For production environments that alternately require roughing and semi-finishing on steel, the geometry and grade deliver a balance between edge strength and abrasion resistance.

Secure seating and straightforward holder compatibility

As an ISO-standard rhombic insert, the component is compatible with a wide range of external holders and boring bars when the holder matches form, relief, tolerance class, fastening method, size and thickness. The 7° relief and 3.97 mm thickness contribute to stable clamping and reduced insert movement under load; the insert’s with hole design and the specified cylindrical hole with single-side countersink ensure consistent location and fastening. These mechanical particulars simplify integration into existing tool systems and help maintain repeatable setup accuracy.

Geometry tuned for intermittent cuts and chip control

The single-sided chipbreaker and single-sided relief strategy combine with a 0.4 mm corner radius to provide positive engagement and controlled chip formation during interrupted or heavy-entrance cuts. The 55° cutting angle of the rhombic shape offers a compromise between approach angle and radial support, helping to limit vibration and protect the cutting edge. Choosing a compatible chipbreaker and matching the insert grade to the workpiece will enhance surface finish and reduce the frequency of edge-related failures.

Improved process security and productivity at scale

Using this insert supports process security through stable chip formation and predictable wear behaviour, which translates into less rework and fewer unscheduled tool changes. The universal nature of the grade covers a broad range of steels, making inventory handling simpler and allowing operators to respond flexibly to changing production requirements. The cumulative effect is higher productivity and more consistent component quality across batch runs and single-part manufacture.

FAQ

What materials is this insert intended for?
The Tungaloy DCMT11T304 T9225 insert is designed primarily for medium to heavy steel turning where robustness and reliable chip control are required.

How does the T9225 coating benefit tool life?
The CVD T9225 coating increases wear resistance while maintaining edge toughness, which is especially beneficial for interrupted cuts and changing engagement conditions in turning operations.

Which holders are compatible with this insert?
Compatibility is determined by insert form, relief angle, tolerance class, fastening, size and thickness; the DCMT11T304 fits standard ISO rhombic external holders that match these parameters.

What cutting geometry should be chosen for interrupted cuts?
The single-sided chipbreaker combined with the 0.4 mm corner radius and the rhombic 55° angle provides secure engagement and controlled chips for interrupted and semi-heavy turning.

Is this insert suitable for both external and internal turning?
Yes, the geometry and grade are suitable for both external and internal turning when a matching holder or boring bar is used.
