DCMT11T308 T9225 — ISO turning insert for medium-to-heavy steel (Tungaloy)

The DCMT11T308 T9225 is an ISO rhombic indexable insert designed for external and internal turning operations where toughness and stable chip control are required.

• ISO rhombic insert DCMT form
• CVD-coated carbide grade T9225
• 0.8 mm corner radius for robust cuts
• Cylindrical hole with 40°–60° countersink

Reliable performance in medium-to-heavy steel turning

The combination of CVD-coated carbide and the T9225 grade delivers a balance of hardness and toughness suited for fluctuating engagement conditions and lightly interrupted cuts. The coating improves thermal resistance and wear behaviour, which translates into longer tool life and fewer interruptions for insert changes. By choosing this geometry and grade, production benefits from predictable tool longevity and consistent part quality, reducing total machining cost per component.

Precise geometry for predictable surface quality and stability

The rhombic form with a 55° principal angle and 0.8 mm corner radius gives a controlled cutting edge that helps maintain dimensional accuracy while offering edge strength for more demanding passes. The 7° relief contributes to secure seating and correct rake geometry in most ISO-compatible holders. A stable clamping arrangement is supported by the insert’s cylindrical hole with one-sided countersink (40°–60°), improving repeatability and reducing vibration-related issues when paired with an appropriate toolholder.

System integration and practical application benefits

As part of an ISO insert system, the plate mates with external holders or boring bars selected by form, clearance angle, tolerance class, fastening method, size and thickness. The one-sided chipbreaker and the universal character of the grade allow selection according to workpiece material and machining stability. For shops aiming to optimise cycle time and reduce unplanned downtime, the insert’s combination of geometry and grade offers efficient chip control and robust cutting performance in turning operations on steel and related alloys.

FAQ

What materials is this insert best suited for?
The DCMT11T308 T9225 is optimised for medium-to-heavy steel turning; the T9225 grade offers toughness and wear resistance suited to fluctuating engagement conditions.

Does the insert require a specific holder type?
Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; use an ISO-compatible holder matched to the rhombic DCMT form.

How does the CVD coating affect performance?
The CVD-coated surface increases thermal stability and wear resistance, resulting in extended tool life and more consistent surface finishes during prolonged turning cycles.

Is this insert suitable for interrupted cuts?
Yes, the T9225 grade provides enhanced toughness for lightly interrupted cuts and variable engagement, improving edge stability under shock loads.

Which chip control can be expected with this geometry?
The one-sided chipbreaker combined with the rhombic shape offers reliable chip control in external and internal turning when matched to appropriate cutting parameters.
