DPMT 11T302 AH6225 ISO turning insert by Tungaloy — PVD‑coated carbide, 55° geometry

DPMT11T302 AH6225 is an ISO‑standard rhombic insert intended for external and internal turning, engineered to deliver a sharp yet stable cutting edge for medium machining of stainless steels

• ISO rhombic insert, 55° cutting geometry
• PVD‑coated carbide for enhanced wear resistance
• Universal grade for stainless steels AH6225
• Centre hole with cylindrical seat and 40°–60° countersink

Longer tool life and consistent edge performance

The PVD‑coated carbide grade AH6225 combines a fine microstructure with a hard, wear‑resistant coating to prolong service intervals under varying conditions. This insert is optimised for machining stainless steels, where a balance between a sharp cutting edge and edge stability is required; the result is predictable tool life and reduced regrinding frequency. The coating reduces built‑up edge and improves thermal stability, which translates into more consistent component dimensions and lower overall cutting costs.

Secure seating and ISO compatibility for reliable clamping

Conforming to ISO norms, the insert’s form, clearance angle and tolerance class ensure straightforward selection and interchangeability with matching holders. The rhombic geometry and the 55° approach angle allow flexible use in a variety of turning set‑ups, while the centre hole with a cylindrical seat and a 40°–60° countersink gives positive seating and repeatable clamping accuracy. This mechanical certainty reduces vibration risks and supports steady cutting conditions, particularly when changing inserts during high‑mix production.

Targeted performance in external and internal turning

Equipped with a single‑sided chipbreaker and a universal chip control design, this insert suits both external profiling and internal turning tasks. When paired with an appropriate holder and cutting parameters, the insert supports good surface finish and controlled chip formation on medium‑duty turning operations. Selecting the matching chipbreaker and feed rate according to the workpiece material will improve process stability and machining throughput, making the setup economical for batches and machining trials.

Practical system considerations for easy maintenance

The cutting system comprises the ISO insert, a compatible external holder or boring bar, and the necessary clamping kit and replacement screws. Keeping a small stock of the same geometry and grade helps maintain machine uptime and simplifies tool management. When installing, ensure the seat area is clean and the clamping screw torqued to the holder manufacturer’s specification to preserve accurate repeatability; regular inspection of the cutting edge will indicate when indexation or replacement is required.
