DNMG 150408 AH6225 indexable turning insert by Tungaloy — PVD carbide, 55° rhombic

The DNMG150408 AH6225 is an ISO-standard indexable turning insert engineered for external and internal turning, offering a reliable cutting edge and universal performance in stainless-steel machining.

• ISO 150408 geometry, 55° rhombic
• PVD-coated AH6225 for stainless steels
• Double-sided chipbreaker, cylindrical hole
• 0.8 mm corner radius for fine profiles

Consistent cutting performance for stainless steels

The insert combines a PVD-coated AH6225 carbide grade with a geometry optimised for a wide range of stainless-steel applications. The coating enhances wear resistance and reduces built-up edge, which results in more predictable tool life and fewer interruptions. Selecting a universal grade means flexibility across varying stainless-steel alloys and cutting conditions while maintaining a sharp, stable cutting edge that supports medium machining tasks.

ISO conformity reduces setup complexity

Compatibility with toolholders is governed by form, 55° clearance, tolerance class, fastening method, size and thickness. Because the insert follows the ISO 150408 standard, integration into existing holder systems is straightforward when the correct clamping and shim are used. The standardised format simplifies inventory management and reduces the time spent checking fitment before each job, helping to maintain steady production throughput.

Improved chip control and surface consistency

Equipped with a double-sided chipbreaker, the insert promotes predictable chip formation and evacuation, which is especially valuable when machining ductile materials such as stainless steels. Controlled chips lower the risk of recutting, protect the workpiece surface and contribute to a consistent surface finish. For operators and planners, better chip control translates into reduced machine cleaning cycles and improved process reliability.

Geometry and dimensions tailored for precision turning

The rhombic insert form and 0.8 mm corner radius enable fine profile work and accessible approach angles in confined geometries. Plate thickness of 4.76 mm provides rigidity for moderate cutting forces, while the cylindrical hole ensures secure fixation in compatible holders. These dimensional characteristics support stable cutting conditions and make the insert suitable for both external and internal turning tasks.

Practical system integration and spare parts

The system comprises the ISO insert, an appropriate external holder or boring bar, a support shim/clamping set and replacement screws; keeping these components aligned ensures consistent clamping and repeatable results. When selecting the chipbreaker and grade, match the insert to the workpiece material and the rigidity of the set-up for best outcomes. Planning for spare shims and screws reduces downtime in series production.

Clear application guidance for planners and operators

For jobs requiring medium cutting depths and changing conditions, this PVD-coated carbide grade offers a reliable compromise between edge sharpness and robustness. The standardised DNMG format aids specification in process sheets and work instructions, enabling repeatable setups and easier cross-referencing in toolrooms. When in doubt about holder compatibility, check form, thickness and fastening details before mounting.
