DNMG 110404 AH6225 Tungaloy indexable insert — PVD-coated carbide for turning, 55° rhombic form

The DNMG110404 AH6225 is an ISO‑standard indexable turning insert designed for external and internal turning applications, optimised for stainless steel machining with a balance of sharpness and edge stability

• ISO rhombic DNMG geometry, 55° cutting angle
• PVD-coated carbide AH6225 for stainless steel
• Double-sided chipbreaker, cylindrical hole
• 0° clearance, 0.4 mm corner radius

Consistent mid-range performance for stainless steel turning

The combination of PVD-coated carbide and the AH6225 grade provides a balanced solution for machining stainless steel under varying conditions. The coating enhances resistance to heat and abrasion, while the substrate maintains a stable cutting edge, which reduces the frequency of interruptions for tool changes. For operations where reliable surface finish and predictable tool life are priorities, this insert offers measurable process stability and helps to maintain throughput.

Simple integration within ISO tool systems

As an ISO indexable insert, the plate fits holders and boring bars whose compatibility is determined by form, clearance, tolerance class, fastening, size and thickness. The rhombic DNMG geometry with a 55° cutting angle and a cylindrical hole allows straightforward mounting in common DNMG holders. This standardisation reduces setup time and simplifies tooling logistics for production lines that rely on repeatable, fast changeovers.

Improved chip control and edge durability

The double-sided chipbreaker design supports controlled chip formation across a range of feeds, aiding swarf evacuation and reducing built-up edge on the workpiece. The modest 0.4 mm corner radius softens engagement peaks to lower the risk of edge chipping during interrupted cuts, while the 0° clearance ensures predictable cutting mechanics. Together, these features contribute to a reliable machining process and consistent component quality.

Practical application guidance for everyday turning

This indexable insert is intended for general external and internal turning tasks where a universal grade is advantageous. Select the AH6225 grade and the appropriate chipbreaker variant according to workpiece material, machining stability and desired surface finish. The symmetrical, double‑edged design permits economical indexing, enabling continued use of the spare edge after rotation, which supports uninterrupted production in batch runs.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The DNMG110404 AH6225 is designed as a universal grade for stainless steel machining, with a PVD-coated carbide substrate tailored for a sharp but stable cutting edge.

Can the insert be used for both external and internal turning?
Yes. The rhombic DNMG form and cylindrical hole permit use in appropriate external holders and boring bars for internal turning where geometry and clamping suit the operation.

How is holder compatibility ensured?
Compatibility depends on insert form, clearance, tolerance class, fastening method, size and thickness; the ISO DNMG110404 designation simplifies selection of matching holders and toolholders.

Does the insert offer indexable edges and chip control?
Yes. The plate is double-sided with a chipbreaker on each edge, enabling indexing to a fresh cutting edge and improved chip control across a range of feeds.

What advantages does the PVD coating provide?
A PVD coating increases surface hardness and thermal resistance, which enhances wear performance and helps to maintain a sharp cutting edge during mid-range machining.
