DNMG110408 AH6225 — ISO turning insert for medium-duty turning, Tungaloy

The DNMG110408 AH6225 is an ISO-standard rhombic turning insert engineered for reliable machining of stainless steel in medium-duty external and internal turning applications.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Rhombic DNMG shape with 55° cutting angle
• Double-sided chipbreaker, cylindrical hole

High performance and consistent cutting edge for stainless steel turning

The combination of a PVD-coated surface and the AH6225 grade carbide delivers a cutting geometry that balances sharpness and edge stability. This blend is designed specifically for stainless steel work, where adhesion and built-up edge can impede productivity; the coating improves wear resistance and reduces friction, while the substrate maintains toughness under variable cutting conditions. The result is a predictable tool life and repeatable part quality, which supports higher process reliability and fewer unplanned interruptions.

Seamless integration into ISO tool systems for quick changeovers

The insert follows ISO norms for form, tolerance and fastening, which simplifies selection and replacement in standard holders and boring bars. Its rhombic shape with a 55° cutting angle and a cylindrical hole supports secure clamping and accurate positioning; the double-sided chipbreaker allows indexable use, halving the number of inserts carried in stock for a given production run. The specified corner radius 0.8 mm provides a controlled edge for medium feeds, and the 0° clearance characteristic suits neutral to slightly positive tool geometries, aiding versatility across turning set-ups.

Practical machining benefits and economical throughput

Designed for medium-duty operations, this insert supports both external and internal turning where varied cutting conditions are encountered. The PVD-coated carbide substrate helps to sustain cutting performance under thermal and mechanical stress, leading to fewer insert changes and lower overall tooling costs. For shops seeking steady surface finish and cycle-time stability, the insert offers a straightforward way to increase throughput without complex process adjustments. For specific material batches or unusual geometries, technical consultation is recommended to match chipbreaker style and cutting parameters to the workpiece.

FAQ

What materials is this insert suitable for? The DNMG110408 AH6225 insert is formulated primarily for stainless steel machining; the AH6225 grade provides a balance of sharpness and edge stability for medium cutting tasks.

Is the insert reversible or single-use? The insert features a double-sided chipbreaker and a rhombic form, enabling reversible indexing to use multiple edges before disposal.

Which holder types are compatible with this ISO insert? Compatibility depends on holder form, free clearance, tolerance class, fastening method, size and thickness; ISO-standard holders designed for DNMG inserts will accept this geometry.

Does the PVD coating require special cutting fluids? The PVD-coated AH6225 insert benefits from common coolant and lubrication strategies used in stainless steel turning; specific coolant choice should align with material and process conditions.

How is the corner radius stated and what does it mean for feeds? The corner radius is 0.8 mm; a larger radius provides stronger edges and improved surface finish at medium feeds, while influencing recommended feed rates and depth of cut.
