DCGW DCGW11T304 DX140 — Turning insert by Tungaloy, PCD for aluminium and non-ferrous metals

A DCGW11T304 DX140 indexable insert engineered for high-speed turning of aluminium, non-ferrous alloys and abrasive non-metals, compatible with ISO holders.

• PCD grade DX140 for high cutting speeds
• Optimised for aluminium and non-ferrous metals
• ISO-compatible rhombic DCGW geometry
• 7° relief angle with cylindrical hole and countersink

Increase throughput with PCD DX140 for long tool life

The polychrystalline diamond (PCD) grade DX140 provides a decisive productivity advantage when machining soft, non-ferrous materials. PCD is a sintered diamond layer on a rigid substrate that resists abrasive wear and maintains a sharp cutting edge at high cutting speeds, so tool changes are less frequent and surface quality remains consistent across long production runs. This material choice is particularly effective where abrasive inclusions or non-metallic fillers accelerate wear with conventional grades.

Consistent clamping and geometric compatibility for repeatable results

The rhombic DCGW form with a 55° included angle and a 7° relief angle ensures stable seating in standard ISO holders and predictable cutting engagement. The insert’s 3.97 mm thickness and 11 mm size conform to ISO tolerances, while the cylindrical hole with a single‑side countersink (40°–60°) secures the insert against rotation and axial movement. These geometric details reduce vibration, support repeatable tool indexing and simplify holder selection for a reliable production setup.

Tailored for turning applications — practical guidance

Designed for external and internal turning operations, this indexable solution ships without a chipbreaker (no chipbreaker) and therefore suits processes where controlled chip evacuation is achieved by tool geometry, holder set-up or low cutting depths. Select the appropriate holder, clamp and screw assembly that match the ISO form, thickness and tolerance class to exploit the insert’s PCD performance. For roughing at high feed rates or finish passes targeting superior surface integrity, the DX140 grade minimises flank wear and preserves cutting-edge geometry.

Lower running costs through fewer interruptions and stable results

Longer insert life directly reduces machine downtime and replenishment frequency, improving overall process economics. The combination of a hard PCD cutting layer and a rigid carrier yields stable edge retention and constant surface finish across batches — an advantage in series production where reproducibility is critical. Where process reliability matters most, the insert delivers measurable reductions in handling time and increased part throughput, supporting quality-focused manufacturing environments.

FAQ

What materials is this insert best suited for?
The DCGW11T304 DX140 insert is optimised for aluminium, other non‑ferrous metals and abrasive non‑metallic workpieces, using the PCD layer to resist wear and extend service life.

Is the insert compatible with standard ISO holders?
Yes, the rhombic DCGW geometry, 3.97 mm thickness and ISO code 11T304 ensure compatibility with ISO‑specified holders that match the form, relief angle and tolerance class.

Does this insert include a chipbreaker?
No, this variant is supplied without a chipbreaker; chip control must be addressed through tool geometry, holder arrangement or cutting parameters.

How does the DX140 grade affect cutting speeds?
The DX140 PCD grade allows elevated cutting speeds compared with conventional carbide grades, enabling higher throughput and extended tool life in suitable materials.
