DCMT11T304 AH120 turning insert for turning applications — Tungaloy

The DCMT11T304 AH120 is an ISO rhombic turning insert designed for external and internal turning, offering a wear-resistant PVD-coated carbide grade for consistent machining performance.

• ISO rhombic 55° form for versatile turning
• PVD-coated carbide AH120 for wear resistance
• 0.4 mm corner radius for accurate profiles
• Cylindrical hole with 40°–60° single countersink

Reliable performance through compact, stable geometry

The insert combines a 55° rhombic form with a robust body to deliver repeatable cutting behaviour in general turning tasks. As an indexable insert its geometry ensures predictable chip load and cutting forces, reducing vibration and enhancing process stability. The PVD-coated carbide substrate helps maintain a sharp edge under interrupted cuts, while the designed relief and thickness contribute to consistent tool life and fewer machine stops.

Precision edge and relief for improved surface finish

A 0.4 mm corner radius paired with a 7° relief angle provides a balance between strength and cutting precision, enabling accurate profile generation and improved surface quality. The 3.97 mm thickness increases rigidity at the cutting zone, which is particularly beneficial when aiming for dimensional accuracy on short overhangs. These geometry choices reduce flank contact and rubbing, translating into better finishes and fewer rework cycles.

Coating and grade engineered for process security

The AH120 grade is a wear- and breakage-resistant PVD-coated carbide developed for demanding turning operations where a sharp cutting edge and process reliability are required. The single-sided chipbreaker facilitates controlled chip formation for a wide range of steels and general materials, helping to avoid chip entanglement and supporting continuous production. Selecting this grade supports longer intervals between index changes and predictable tool performance.

System compatibility and practical handling for workshop use

The insert is manufactured to ISO standards and its compatibility with holders is determined by form, relief angle, tolerance class, fastening method, size and thickness. The cylindrical hole with a single countersink (40°–60°) simplifies secure clamping in numerous standard clamping systems. In practice, a complete working set comprises the insert, matching external holder or boring bar, a shim or clamp set and the correct fastening screws, enabling fast replacement and minimised downtime.

FAQ

What materials is this insert suitable for?
The AH120 grade of the DCMT11T304 insert is designed for general turning applications and provides broad coverage across common steels and general workshop materials due to its wear-resistant PVD-coated carbide.

How does the 0.4 mm corner radius affect finishing?
A 0.4 mm corner radius on the DCMT11T304 helps to produce accurate profiles with improved surface quality while maintaining sufficient edge strength for most general turning tasks.

Is the insert compatible with standard ISO holders?
Yes, the ISO-compliant geometry of this insert ensures compatibility when the holder matches form, relief angle, tolerance class, fastening method, size and thickness; the cylindrical hole with single countersink supports secure clamping.
