DCMT 11T304 AH6225 – Turning indexable insert (ISO), PVD-coated carbide, Tungaloy

The DCMT11T304 AH6225 is an ISO-standard rhombic turning insert engineered for external and internal turning of stainless steels and similar materials, offering a balance of sharpness and edge stability for medium machining operations.

• PVD-coated carbide grade AH6225
• Designed for stainless steels
• 7° clearance angle, 55° included angle
• 0.4 mm corner radius, rhombic form

Precise ISO compatibility for reliable tool selection

The insert is supplied as an ISO-series indexable insert, so compatibility with a chosen holder is determined by the insert’s form, relief angle, tolerance class, attachment method, size and thickness. Using ISO-standard geometry simplifies tool selection and reduces setup time in production environments. The rhombic plate shape and the central hole with a cylindrical bore plus a single-side countersink (40°–60°) ensure positive clamping and repeatable seating in most commercial external and internal turning toolholders, supporting process stability and predictable tool life.

Material and coating engineered for stainless-steel turning

Manufactured from PVD-coated carbide, grade AH6225, the insert is intended as a universal solution for stainless steels, combining a sharp yet stable cutting edge with improved wear resistance. The PVD coating enhances thermal and abrasive resistance, which helps to maintain edge integrity under varying cutting conditions and fluctuating feeds. The single-sided chipbreaker is tuned to produce controllable chip forms during medium cutting, aiding chip evacuation and protecting the machined surface finish while contributing to economical tool consumption and consistent cycle times.

Geometry and system build that improve productivity

The rhombic geometry with a 55° included angle and a 0.4 mm corner radius provides a versatile cutting edge for medium finishing and semi-finishing operations, while the 7° relief angle reduces rubbing and supports a defined cutting action. With a plate thickness of 3.97 mm and plate size 11, the insert balances rigidity and cutting accessibility in constrained setups. The central hole design (cylindrical with one-sided countersink) enables secure clamping with standard screws and pads; a matching holder, backing pad and spare screws complete the system and help to achieve repeatable seating and minimal vibration during turning.

FAQ

What machining operations is this insert suitable for?
The DCMT11T304 AH6225 insert is designed for external and internal turning, providing suitable geometry and chip control for medium finishing and semi-finishing operations when machining stainless steels.

How does the AH6225 grade affect performance?
The AH6225 PVD-coated carbide grade offers a balance of sharpness and edge stability for stainless steels, improving wear resistance and helping to maintain consistent surface quality under variable cutting conditions.

Which holder features are required for correct compatibility?
Compatibility is determined by the insert’s form, relief angle, tolerance class, attachment method, size and thickness; the DCMT11T304 requires a holder and clamping set that match its rhombic shape, central hole style and 3.97 mm thickness.

What chip control can be expected with this insert?
The single-sided chipbreaker on the DCMT11T304 promotes controlled chip formation during medium cutting, aiding chip evacuation and reducing the risk of surface damage on the workpiece.

Is the insert supplied with screws or clamping parts?
The delivery typically covers the insert itself; a complete system comprises the matching external holder or boring bar, backing pad/clamp set and replacement screws, which should be selected to suit the DCMT11T304 geometry.
