DCMT 070208 AH6225 ISO turning insert by Tungaloy — PVD-coated carbide, 7° relief

The DCMT070208 AH6225 is an ISO turning insert designed for external and internal turning of stainless steels under varying machining conditions.

• PVD-coated carbide grade AH6225
• 7° relief for versatile turning
• 0.8 mm corner radius for robustness
• Cylindrical hole with 40°–60° countersink

Reliable cutting performance for stainless steel turning

The combination of a PVD-coated carbide substrate and the AH6225 grade produces a predictable wear behaviour suited to medium machining of stainless steels. The coating increases resistance to adhesive wear and heat, while the substrate maintains edge stability under fluctuating cutting conditions. This results in fewer tool changes, improved uptime and a consistent surface finish, making the insert an economical choice for batch and job‑shop production alike.

Geometry engineered for secure clamping and repeatability

The ISO rhombic form (DCMT 07) with a 55° included angle and 0.8 mm corner radius provides a balance between strength and profile definition. The insert sits on a cylindrical hole with a one‑sided countersink (40°–60°) for positive, repeatable seating; the 2.38 mm thickness contributes to rigidity and vibration damping. With a 7° relief angle, the geometry reduces rubbing and thermal loading, improving tool life and dimensional stability when matched to the correct holder and tolerance class.

Predictable chip control and process stability

Equipped with a one‑sided chipbreaker, the insert supports controlled chip formation in turning applications, reducing the risk of long, stringy chips that disrupt machining. The chipformer is designed to work with the AH6225 grade to break and guide chips away from the cutting edge, lowering rework and enhancing operator safety. In short, the system improves cycle times through fewer interruptions and more consistent material removal.

Simple integration and low-maintenance handling for production

The ISO conformity of the design enables straightforward replacement and inventory management across standard toolholders and toolposts. The insert is suitable for both external and internal turning when the correct chipbreaker and grade are selected for workpiece stability. The DCMT070208 AH6225 insert provides a reliable baseline solution that simplifies tool selection and reduces setup time in mixed‑material operations.
