DNMG 150616 AH6225 Turning Insert (DNMG150616 AH6225) — Tungaloy

The DNMG150616 AH6225 is a rhombic, ISO-standard indexable turning insert designed for general turning of stainless steels, offering a balanced combination of sharpness and edge stability for medium-duty machining.

• Universal grade for stainless steels AH6225
• PVD-coated cemented carbide substrate
• 55° rhombic geometry for diverse turning tasks
• Double-sided insert with cylindrical hole
• 1.6 mm corner radius for consistent profile

High-efficiency turning with predictable tool life

The combination of a PVD-coated surface and a cemented carbide substrate makes this insert suitable for stable, repeatable results in batch and continuous turning. The AH6225 grade is optimised to maintain a sharp, wear-resistant edge across varying cutting conditions, which contributes to longer tool life and fewer index changes. For production environments seeking throughput without excessive regrinding, this geometry supports efficient chip formation and reliable dimensional control.

Geometry and handling benefits that simplify setup

Featuring a 55° rhombic shape and a 1.6 mm corner radius, the insert delivers a compromise between strength and finish capability. The double-sided design with a cylindrical hole reduces inventory per toolholder and simplifies replacement procedures, while the ISO standardisation ensures compatibility where form, relief angle, tolerance class, fastening and thickness match the holder. These attributes reduce machine downtime and allow quick adaptation between external and internal turning operations.

Application-focused performance for stainless steels

Specifically developed as a universal solution for stainless steels, the grade supports medium machining parameters where surface quality and edge stability are required. The integrated chipbreaker geometry is suited to a range of feeds and depths of cut, helping to control chip flow and avoid entanglement. Where material variability or intermittent cuts are encountered, the balanced edge preparation of this grade lowers the risk of premature edge failure compared with uncoated alternatives.

Practical considerations for workshop integration

As an ISO-specification indexable insert, compatibility with the tooling system depends on correct match of insert form and holder specification. The PVD-coated surface tolerates a variety of cooling strategies; however, recommended cutting data should be validated for the specific stainless grade and machine rigidity. For operations seeking a straightforward, economical insert that combines easy handling with consistent machining results, this option represents a sound choice within mid-range performance classes.

FAQ

What materials is this insert designed for?
The DNMG150616 AH6225 insert is specified as a universal grade for stainless steels, providing a balanced edge for medium-duty turning of a wide range of stainless alloys.

How does the AH6225 coating affect performance?
The AH6225 PVD-coated surface increases wear resistance and edge life compared with uncoated grades, improving process stability during standard turning operations.

Is the insert compatible with standard ISO holders?
Yes, the DNMG150616 designation follows ISO geometry; compatibility requires matching holder form, relief angle, tolerance and thickness to ensure correct seating and clamping.

Can the double-sided design reduce tooling costs?
The double-sided construction with a cylindrical hole allows two usable cutting edges per indexation, which can reduce the number of spare inserts required and simplify inventory management.

What corner radius is most suitable for finishing?
The 1.6 mm corner radius offers a balance between strength and surface finish; finer radii may be preferred for high-quality finishing, while 1.6 mm supports robust profile stability in general turning.
