DCGW 070200 DX140 turning insert (PCD) for turning — Tungaloy

The DCGW070200-DIA DX140 is an ISO-standard PCD turning insert designed for high-speed external and internal turning of aluminium and other non-ferrous or abrasive non-metals.

• PCD grade DX140 for extended tool life
• ISO-standard rhombic shape with 55° geometry
• 7° clearance and cylindrical hole plus countersink
• Optimised for aluminium and non-ferrous metals

Increase uptime with a wear-resistant PCD grade

The PCD grade DX140 cutting material offers exceptionally long tool life when machining aluminium and other abrasive non-metals, enabling sustained high cutting speeds and fewer insert changes. The diamond-based cutting edge resists abrasive wear far better than conventional coatings, which translates into more consistent part quality and longer uninterrupted production runs. As a result, machining cycles become more predictable and planning for tool replacement is simplified.

Precise fit and secure clamping for stable cutting

Built to ISO dimensions, the insert’s 55° rhombic geometry and 7° clearance ensure defined engagement with compatible holders; the insert size is 07 with a plate thickness of 2.38 mm, and the fastening hole is a cylindrical hole with one-sided countersink (40°–60°). These measurable parameters allow a straightforward match to matched external holders or boring bars, providing reliable clamping and repeatable positioning that support dimensional accuracy and surface finish across batches.

Application-focused performance for turning processes

Designed for both external and internal turning, this ISO-series insert pairs the DX140 chipformer with the appropriate holder and process settings to control chip shape and evacuation. The DIA chipbreaker is particularly effective with soft, stringy aluminium alloys and abrasive non-metals, reducing the risk of built-up edge and helping to maintain a consistent cutting force. When combined with a suitably rigid setup and correctly selected feed and speed, process stability and product quality improve measurably.

System considerations and integration into your tooling setup

The working system comprises the ISO turning insert plus a suitable external holder or boring bar, a shim/clamping set and replacement screws. Compatibility is determined by the insert’s form, clearance angle, tolerance class, fastening method, size and thickness, so selecting a matching holder is essential for safe, productive machining. For inventory and traceability the article number and manufacturer SKU are available for ordering and reordering, ensuring rapid replacement in production environments.

FAQ

What materials is this insert best suited for?
The DCGW070200-DIA DX140 Tungaloy turning insert (SKU 6802859-Tungaloy) is optimised for aluminium, other non-ferrous metals and abrasive non-metals, where the PCD cutting material delivers superior wear resistance.

How does the DX140 PCD grade affect machining performance?
The DX140 PCD grade provides extended tool life and consistent edge performance during high-speed turning, which reduces insert changes and helps maintain repeatable surface quality with the DCGW ISO insert.

Which holders are compatible with this ISO insert?
Compatibility requires a holder that matches the insert’s form, 55° geometry, 7° clearance, size 07 and 2.38 mm thickness; clamping systems designed for ISO rhombic inserts with a cylindrical hole and countersink will be suitable.

Can this insert be used for both external and internal turning?
Yes, the ISO design of the DCGW insert supports both external and internal turning operations when paired with the correct external holder or boring bar and process parameters.

What is the purpose of the DIA chipbreaker?
The DIA chipbreaker is tailored to produce controlled chips when machining soft or abrasive materials such as aluminium, improving evacuation and reducing the likelihood of chip-related interruptions.
