DCGW 11T308 DX140 turning insert by Tungaloy — PCD grade for high-speed aluminium turning

DCGW11T308 DX140 is an ISO rhombic turning indexable insert designed for high-speed machining of aluminium, non-ferrous metals and abrasive non-metal materials; suited to both external and internal turning applications.

• Polychrystalline diamond (PCD) cutting grade DX140
• ISO rhombic form DCGW 11T308 with 55° angle
• Cylindrical hole with single-sided countersink
• Long tool life for abrasive non-metal materials

Faster aluminium and non-ferrous machining with PCD performance

The PCD cutting layer in grade DX140 offers extremely low wear rates when machining aluminium and similar soft, abrasive materials. This translates into high cutting speeds and fewer tool changes, reducing cycle times and improving productivity on serial turning operations. Polykristalliner Diamant provides a hard, wear-resistant cutting edge with minimal built-up edge tendency, which also helps to maintain stable surface finish over long runs. For operations where short setup time and long tool life matter, this insert achieves measurable time savings and consistent part quality.

Precise ISO fit and secure clamping for repeatable results

Designed as an ISO-standard insert, the component’s compatibility with holders depends on form, relief, tolerance class, fastening, size and thickness. The rhombic geometry with a 55° cutting angle and 7° clearance ensures predictable cutting behaviour and chip flow. The cylindrical hole with single-sided countersink (40°–60°) offers reliable centring and clamping; the plate thickness of 3.97 mm and the size designation 11 define the correct seat geometry for compatible external holders or boring bars. Proper selection of holder and shim set means repeatable seating, accurate runout and improved tool life.

Practical guidance for shop-floor application and system setup

Use this PCD-indexable insert for external turning and internal turning of aluminium, brass and abrasive non-metal materials; avoid use on hardened steels or materials that generate excessive cutting temperatures unsuitable for diamond. The system comprises the ISO insert, a matching external holder or boring bar, an underlay or clamping set and replacement screws. Note that this insert is supplied without a chipbreaker, so cutting parameters and feed must be selected to match workpiece stability and material removal rate. The clear benefit is fewer interruptions for tool changes and steady surface quality across production batches.

FAQ

What materials is this insert best suited for?
The DCGW11T308 DX140 insert is intended primarily for aluminium, non-ferrous metals and abrasive non-metal materials, where the PCD cutting edge delivers long life and consistent surface finish.

Can this insert be used for internal turning on a boring bar?
Yes, the ISO rhombic form and the cylindrical hole with countersink allow secure clamping in suitable boring bars for internal turning operations.

Is there a chipbreaker included with this insert?
This insert is supplied without a chipbreaker; cutting parameters should be adapted and a suitable holder chosen to ensure stable chip control.

How does the DX140 grade affect tool life?
The DX140 PCD grade is formulated for high wear resistance during high-speed cutting of soft, abrasive materials, resulting in significantly extended tool life compared with conventional grades.

What does the system setup for using this insert include?
A typical setup comprises the ISO insert, a compatible external holder or boring bar, an underlay/clamping set and replacement screws for correct mounting and repeatable seating.
