DNMG 150612 AH6225 Tungaloy turning insert — PVD‑coated cemented carbide, 55° geometry

A DNMG150612 AH6225 Tungaloy turning insert designed for external and internal turning of stainless steel, offering a balance of sharpness and edge stability for medium cutting conditions.

• PVD‑coated cemented carbide AH6225
• ISO DNMG 55° rhombic geometry
• Double‑sided chipbreaker, cylindrical hole
• Sharp, stable cutting edge for stainless steels

Reliable performance for varied turning tasks

The combination of a PVD coating with a cemented carbide substrate in grade AH6225 provides consistent wear resistance and heat protection during turning of stainless steel. This grade is formulated to deliver a sharp cutting edge while maintaining edge stability under changing conditions, which translates into more predictable tool life and fewer interruptions for insert changes. The rhombic geometry contributes to good access in external and internal operations without sacrificing strength.

Seamless integration into ISO turning systems

Built to the ISO DNMG profile, the insert matches common holder geometries so compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness. The cylindrical hole and double‑sided design allow economical indexing in suitable external holders or boring bars, while the 55° lead angle supports versatile approach angles. System components such as a matching outer holder, shim/clamping set and replacement screws complete the assembly for a secure fit and repeatable positioning.

Improved productivity through chip control and geometry

A double‑sided chipbreaker coupled with a corner radius of 1.2 mm helps to manage chip formation and evacuation, reducing the risk of entanglement and enabling steady material removal. The 55° geometry distributes cutting forces favourably, supporting stable cutting at moderate depths of cut. Together, the AH6225 grade and the insert geometry aim to enhance process reliability and reduce downtime, making the tool a practical choice for shops seeking consistent results on stainless steel workpieces.

Practical guidance for selection and use

For best outcomes, select a chipbreaker and grade that match the workpiece material, machining setup and required surface finish; this insert is intended for medium machining of stainless steel where a balance of sharpness and durability is needed. When rigid clamping and stable toolholding are available, the insert’s features deliver repeatable performance in both external and internal turning operations. If there is uncertainty about matching the insert to a specific holder or application, Metav Werkzeuge’s technical advisers can provide tailored recommendations.
