DNMG 150404 AH6225 Tungaloy turning insert — PVD-coated carbide, rhombic 55° for turning

A DNMG150404 AH6225 Tungaloy insert designed for ISO-series external and internal turning, offering a sharp yet robust cutting edge for variable conditions and principally intended for stainless-steel machining

• PVD-coated carbide for stainless steels
• Rhombic DNMG shape with 55° cutting angle
• Double-sided chipbreaker for versatile turning
• Cylindrical hole and 4.76 mm plate thickness

Versatile cutting performance for medium turning operations

The selected AH6225 grade is a PVD-coated carbide designed to combine a sharp cutting geometry with edge stability under changing conditions. In practice, this means consistent dimensional results when machining stainless steels, with the coating contributing to improved wear resistance and thermal stability. The insert’s configuration supports medium cutting depths and offers a balance between surface finish and tool life, so machining processes run more predictably and require fewer unscheduled tool changes. This reduces downtime and contributes to overall process efficiency.

Predictable fit and secure clamping for process reliability

Compatibility within the ISO-series is determined by form, relief angle, tolerance class, fastening method, size and thickness; the rhombic DNMG profile with a 55° cutting edge and a cylindrical hole ensures repeatable seating in standard external holders or boring bars. The insert’s 0° relief angle and 0.4 mm corner radius provide a compromise between strength and finish—small radii improve edge robustness while still permitting fine surface quality. Selecting the correct holder geometry and clamping kit is essential for reliable performance and repeatable tool offsets.

Better chip control and uptime through engineered geometry

A double-sided chipbreaker minimises uncontrolled chip formation across a range of feeds and materials, which eases swarf evacuation and protects the cutting edge. The 4.76 mm plate thickness increases rigidity compared with thinner grades, lowering vibration risk and helping to maintain tool life. Combined, these features support higher productive time between indexings and enable economical batch runs. The insert’s layout also permits two usable cutting edges per side, effectively extending service intervals before replacement is necessary.

System considerations that simplify tool selection and set-up

To assemble a reliable tooling system, pair the ISO insert with a compatible external holder or boring bar, a suitable underlay or clamping set, and correct fastening screws. Choosing the right chipbreaker and grade according to workpiece material and machining stability yields measurable improvements in processing speed and surface quality. Where changing operations or materials are expected, favour the universal grade and the double-sided breaker to maintain consistent results without frequent insert changes.

FAQ

What materials is this insert suitable for?
The AH6225 grade is formulated for machining stainless steels; the DNMG150404 insert from Tungaloy performs well in medium turning conditions on these materials.

How does the chipbreaker affect machining stability?
The double-sided chipbreaker on this insert improves chip control across variable feeds, reducing swarf issues and contributing to steadier cutting conditions with fewer interruptions.

Is the DNMG150404 compatible with standard ISO holders?
Yes; the insert follows ISO series dimensions, but correct compatibility depends on matching form, clearance angle, tolerance class, fastening and thickness with the chosen holder.

How many cutting edges are available per insert?
This double-sided DNMG plate provides multiple usable edges; indexing extends service life and lowers the frequency of inserts replacement.

What advantages does the PVD coating deliver?
The PVD coating on the AH6225 grade increases wear resistance and thermal stability, resulting in improved edge life and more consistent surface quality during medium turning.
