DNMG 150408 AH6225 turning indexable insert (DNMG format) – Tungaloy

DNMG 150408 AH6225 is a compact turning insert for external and internal machining; optimised for medium cutting and variable conditions in stainless steel

• PVD-coated carbide AH6225
• Optimised for stainless steel
• 55° rhombic geometry for versatile turning
• Double-sided chipbreaker with centre hole

Consistent performance for stainless steel with a universal grade

The DNMG 150408 AH6225 insert is based on a PVD-coated carbide substrate and the AH6225 grade, engineered as a universal solution for machining stainless steel. The coating increases wear resistance under fluctuating temperatures and intermittent cuts, while the substrate maintains a precise cutting edge for repeatable results. For industrial turning operations this combination reduces downtime by prolonging edge life and enabling predictable tool-change intervals. The universal character of the grade supports a broad material range without frequent insert swaps, improving process stability and overall throughput.

Stable edge geometry and effective chip control for reliable cycles

A 55° rhombic shape provides a versatile approach angle and a balanced contact zone, which helps to maintain a stable cutting edge under varying setup stiffness. The insert's 55° geometry together with a 0° clearance specification and a 0.8 mm nose radius promotes a controlled cut and a consistent surface finish in medium machining. The double-sided chipbreaker and the central cylindrical hole assist secure seating and repeatable chip flow, preventing entanglement and reducing the risk of built-up edge. In practical terms, this means fewer interruptions and a smoother production rhythm for turning operations.

ISO compatibility and integration into turning systems

Manufactured to the ISO standard DNMG format, the insert interfaces with holders according to form, relief angle, tolerance class, fastening method, size and thickness. Compatibility requires a suitable compatible holder, appropriate clamping geometry and the correct locking set or screw; these components create the complete system: insert, holder, backup shim and fastening hardware. This standardisation simplifies inventory management and makes tool reprovisioning straightforward in mixed-machine shops, enabling fast interchangeability across lathes and bar-type holders.

Application scope and process advantages for workshops

Designed for both external and internal turning, the insert performs best in medium machining where balance between edge life and productivity matters. The universal chipbreaker choice offers flexibility: select the chipformer and grade combination aligned with workpiece material, cutting parameters and machine rigidity. The result is a cost-effective solution that minimises tool-change frequency while delivering repeatable dimensional accuracy and good surface quality in serial production or job-shop environments.

FAQ

What materials is this insert suited for? The DNMG 150408 AH6225 insert is optimised for machining stainless steel and provides a universal solution for a range of stainless-type alloys.

How does the AH6225 grade influence tool life? The AH6225 PVD-coated carbide offers enhanced wear resistance under variable conditions, improving edge stability and extending service life compared with uncoated grades.

Is the insert reversible or single-use? The insert is double-sided with two usable edges per side, enabling multiple indexings before disposal and improving cost efficiency.

What holder compatibility is required for this ISO insert? Compatibility depends on holder form, relief angle, tolerance class and fastening; an ISO-compatible DNMG holder with matching clamping and a suitable locking set is required for secure use.

Which operations are recommended for this insert? Best suited to medium turning tasks — both external and internal turning — where a balance of surface finish and productivity is required; the chipbreaker and grade should be matched to workpiece stability.
