DCMT 11T308 AH6225 – Tungaloy indexable insert for turning, PVD‑coated carbide, 0.8 mm radius

The DCMT11T308 AH6225 is an ISO‑standard rhombic indexable insert designed for reliable external and internal turning on corrosion‑resistant steels and similar alloys

• PVD-coated carbide grade AH6225
• Suited to corrosion-resistant steels
• 55° rhombic shape, 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Consistent edge performance for medium turning

The combination of a PVD‑coated surface and the AH6225 carbide formulation produces a stable cutting edge that withstands fluctuating conditions common in batch production and mixed‑material jobs. This material pairing reduces notch wear on austenitic and ferritic workpieces and supports longer index intervals, which translates into fewer tool changes and improved throughput. The PVD finish also helps maintain a smooth flank contact for repeatable surface quality.

ISO compatibility and secure clamping for predictable results

Built to ISO dimensions, the insert's 55° rhombic geometry and precise plate thickness ensure compatibility with a wide range of external holders and boring bars. The cylindrical hole with one‑sided countersink (40°–60°) provides secure fastening and minimises micro‑movement under heavy interrupted cuts. Clear specification of shape, clearance angle and tolerance class simplifies toolholder selection and reduces downtime associated with incorrect matching.

Geometry tuned for finish and strength

A 0.8 mm corner radius balances edge strength and surface finish: the modest radius supports improved chip formation and reduces the tendency for edge chipping compared with sharper radii, while still allowing good contour definition. The one‑sided chipbreaker is profiled for medium machining, promoting controlled chip flow and reduced heat concentration at the cutting zone. With a 7° clearance, the insert offers stable contact geometry that assists in consistent cutting forces and repeatable part tolerances.

FAQ

Which materials is this insert best suited for?
The DCMT11T308 AH6225 insert is optimised for corrosion‑resistant steels and similar alloys; the AH6225 grade and PVD finish provide balanced wear resistance and edge sharpness for these materials.

How does the 0.8 mm radius influence surface finish and tool life?
A 0.8 mm corner radius increases edge robustness compared with finer radii, improving resistance to chipping while still allowing good surface finish when cutting with moderate feeds.

What clamping features ensure secure mounting?
Compatibility is achieved through ISO sizing and the insert's cylindrical hole with a one‑sided countersink (40°–60°), which enables safe, repeatable seating in standard external holders and boring bars.

Is this insert suitable for internal turning operations?
Yes, the rhombic 55° form and chip control geometry make the insert appropriate for both external and internal turning tasks, provided a matching ISO‑compliant boring bar or holder is used.
