DCMT11T308 AH8015 ISO rhombic turning insert for general turning (Tungaloy)

The DCMT11T308 AH8015 is an ISO‑standard, rhombic turning insert designed for external and internal turning of heat‑resistant alloys and general machining tasks.

• ISO‑standard rhombic insert 55° geometry
• PVD‑coated carbide grade AH8015
• One‑sided chipbreaker for predictable chips
• Compatible with holders using cylindrical hole

Longer tool life and balanced wear for heat‑resistant alloys

The PVD‑coated AH8015 grade provides a balanced combination of wear resistance and edge stability, making it a dependable choice for machining heat‑resistant alloys. The PVD‑coated surface reduces adhesive wear and improves resistance to thermal loading, which translates into longer effective tool life and fewer unexpected tool changes. For manufacturers seeking consistent component quality, this grade offers a reliable compromise between life and toughness, enabling steady cycle times in mixed production.

Accurate geometry and controlled chip formation for predictable results

The rhombic ISO geometry with a 55° main angle and a 0.8 mm corner radius supports a stable cutting action and favourable cutting forces during turning. The insert features a one‑sided chipbreaker, which produces predictable chip forms when matched with the correct holder and cutting parameters. The insert is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) to ensure secure clamping and repeatable positioning. These design elements reduce set‑up variation and simplify process qualification for both external and internal turning.

System compatibility and practical workshop benefits

As part of an ISO insert system, the DCMT format is intended to work together with a suitable external holder or boring bar, shim/clamping set and replacement screws, which streamlines replacement and maintenance. The insert’s 3.97 mm thickness and rhombic form support robust seating and resistance to deflection in moderate to heavy cuts. Using standardised components reduces downtime and supports predictable batch production, helping workshops maintain throughput and achieve consistent surface finish and dimensional control.

FAQ

Is this insert suitable for machining heat‑resistant alloys?
Yes. The AH8015 grade is specified for general machining of heat‑resistant alloys and provides a balanced mix of wear resistance and edge stability for the DCMT11T308 insert.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic ISO profile and the cylindrical hole with countersink make it compatible with standard DCMT external holders and boring bars.

What chip form can be expected with the one‑sided chipbreaker?
The one‑sided chipbreaker promotes predictable chip control when cutting parameters match the workpiece material and the selected grade; AH8015 supports stable chips in a range of heat‑resistant alloys.

Can the insert handle moderate to heavy cuts?
With a thickness of 3.97 mm and a robust rhombic shape, the insert provides good seating and resistance to deflection for moderate to heavy turning operations.

What is the manufacturer article number and SKU for ordering?
The manufacturer article number is 6747779 and the Metav SKU is 6747779-Tungaloy for the DCMT11T308 AH8015 indexable insert.
