DCMT 11T312 AH725 – ISO turning insert for external and internal turning (Tungaloy)

A DCMT11T312 AH725 rhombic turning insert engineered for reliable external and internal turning operations, offering universal performance and high process security across a range of steels and stainless steels

• PVD-coated, breakage-resistant grade AH725
• ISO-standard rhombic insert, 55° lead
• 1.2 mm corner radius for robust edges
• Cylindrical hole with 40°–60° countersink

Consistent results from a universal, resistant grade

The AH725 grade is a PVD‑coated carbide designed for universality and resistance to edge breakouts, which translates into stable chip formation and reliable performance when machining varying workpiece materials. In everyday shop use, this reduces unexpected tool failures and supports repeatable quality in both short runs and mixed‑material batches. The grade’s robustness is particularly advantageous for smaller tooling assemblies and for operations where process security is critical, as it maintains edge integrity under fluctuating cutting conditions.

Fast integration and interchangeability with ISO geometry

The insert’s ISO designation and rhombic form enable straightforward replacement and compatibility with a wide range of external holders and boring bars. Key geometry details such as the 55° lead angle, 7° clearance, 1.2 mm corner radius and a 3.97 mm plate thickness ensure predictable seating and cutting behaviour. The insert features a cylindrical hole with a single‑sided countersink (40°–60°), which supports secure clamping and consistent reference positioning. Because compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness, specifying these values simplifies tooling choices and minimises setup time.

Practical shop‑floor benefits: fewer interruptions, better throughput

Using a universal, breakage‑resistant grade means fewer tool changes and reduced machine downtime, yielding measurable productivity gains. The rhombic plate form and single‑sided chipbreaker are balanced for controlled chip flow in common turning tasks, helping to avoid chatter and improve surface finish on steel and stainless steels. For varied materials or higher demands on process stability, selecting the appropriate chipbreaker and the AH725 grade delivers reliable tool life and consistent component quality, supporting cost‑effective production and predictable maintenance cycles.
