DCGW11T302 DX140 Turning Insert (PCD, 55°) — Tungaloy

The DCGW11T302 DX140 is an ISO‑standard rhombic PCD insert designed for high‑speed external and internal turning of aluminium and other non‑ferrous and abrasive non‑metallic materials.

• ISO‑standard rhombic geometry for precise turning
• DX140 PCD grade for long tool life
• 55° cutting angle for versatile external/internal work
• Cylindrical hole with countersink for secure clamping

Boosted cutting productivity with PCD technology

The combination of PCD cutting material and the DX140 grade delivers measurable benefits in cycle time and tool life: PCD resists abrasive wear far better than conventional grades, so machining of aluminium and other non‑ferrous materials can be run at high cutting speeds with reduced insert changes. The rhombic 55° geometry contributes to stable cutting forces and improved chip flow, which supports a consistent surface finish and fewer interruptions in production. Because the substrate is based on a carbide body with a PCD cutting top, the result is an insert that balances edge strength with wear resistance for sustained performance.

Reliable clamping and ISO compatibility for repeatable results

The insert conforms to ISO dimensions and its fit depends on form, relief angle, tolerance class, fastening, size and thickness — design choices that simplify integration into standard toolholders. The cylindrical hole with countersink (40°–60°) provides secure seating and repeatable positioning, reducing vibration and variances between assemblies. The modest 0.2 mm corner radius and 7° relief angle support accurate profile turning and controlled corner strength, giving machinists a predictable platform for both finishing and light roughing tasks.

Material suitability and economical machining strategy

The DX140 polykristalline diamond grade is optimised for aluminium, other non‑ferrous alloys and abrasive non‑metallics; it enables long runtimes and stable edge line when machining challenging surfaces. Selecting the appropriate chipbreaker or grade variant for the specific alloy and stability conditions remains important — inserts without a chipbreaker can be the best choice where chip control is managed by toolpath and coolant strategy. The overall system concept — ISO insert, matching external holder or boring bar, plus shim and fastening hardware — allows straightforward replacement and predictable process behaviour, leading to lower unit costs through reduced downtime.

FAQ

What materials is this insert best suited for?
The DCGW11T302 DX140 insert is designed primarily for aluminium and other non‑ferrous alloys as well as abrasive non‑metallic materials, taking advantage of the DX140 PCD grade for extended runtimes.

How does the DX140 grade affect machining performance?
The DX140 polykristalline diamond grade provides high wear resistance and enables high cutting speeds, resulting in longer intervals between insert changes and improved productivity when machining suitable materials.

Which holders are compatible with this ISO insert?
Compatibility follows ISO standards and depends on form, relief angle, tolerance class, fastening, size and thickness; the insert is intended for use with matching external holders or boring bars that accept ISO rhombic DCGW‑type inserts.

Does this insert include a chipbreaker?
This specific variant is supplied without a chipbreaker; chip control should be achieved via toolpath, coolant and the chosen holder for the application.

What clamping feature ensures repeatable seating?
A cylindrical hole with a one‑sided countersink (40°–60°) secures the insert and ensures repeatable positioning when mounted with the correct screw and clamp system.
