DCMT11T304 AH6235 Tungaloy ISO turning insert — PVD-coated carbide, 0.4 mm radius

DCMT11T304 AH6235 is an ISO-form indexable insert designed for turning tasks, optimised for stainless steels and interrupted cutting where edge robustness and consistent chip control are required.

• PVD-coated carbide AH6235 for stainless steels
• 0.4 mm corner radius for fine finishing
• Rhombic ISO insert, 11 mm size, 55° geometry
• Countersunk hole mounting, thickness 3.97 mm

Increased productivity through durable coating and material choice

The combination of a PVD-coated surface and a carbide substrate provides a balance of wear resistance and fracture toughness that suits high-demand turning operations. The AH6235 grade is formulated for tougher machining tasks, notably when working with stainless steel or when frequent interruptions in the cut increase the risk of chipping. This results in longer edge life and fewer insert changes, which improves uptime and reduces tooling costs per component—a tangible productivity advantage for machining shops and production lines.

Faster set-up and reliable holder compatibility for consistent results

Compatibility with standard ISO toolholders is determined by insert form, clearance angle, tolerance class, fastening and thickness. The rhombic geometry and 55° lead angle make the insert suitable for both facing and light profiling, while the cylindrical hole with a single‑side countersink ensures secure clamping in most ISO assemblies. Selecting the correct chipbreaker and grade for the workpiece and stability of the setup reduces vibration and improves surface finish. For bespoke holder interfaces or to confirm fitment, Metav Werkzeuge can provide precise advice and specifications.

Precise geometry explained for predictable surface finish

A 0.4 mm corner radius offers a compromise between edge strength and surface quality: larger radii tend to increase stability and tool life but can raise cutting forces; smaller radii give finer detail but less robustness. The 7° clearance angle limits rubbing on the flank face, helping to maintain dimensional accuracy and thermal stability during continuous cuts. The one‑sided chipbreaker is designed to direct chips away from the cutting zone during turning, which minimises recutting and supports consistent part quality in both external and internal turning operations.

Practical application advice and expected outcomes

In practice, this insert performs well for turning tasks where occasional interruptions or minor workpiece inconsistencies are expected. The AH6235 grade is suited to achieving repeatable results on stainless steels, delivering good surface integrity with fewer edge failures. Choosing a compatible holder and optimising cutting parameters for chip control will typically reduce cycle times and tooling consumption. For production environments seeking repeatability and reduced process variation, the insert offers a reliable component in a productive tooling system.
