CPGA090204 DX140 Tungaloy Turning Insert (PCD, ISO rhombic 80°)

The CPGA090204 DX140 is an ISO-formatted rhombic turning insert designed for high-speed machining of aluminium and other non-ferrous and abrasive non-metal materials.

• PCD grade DX140 for long tool life
• ISO CPGA090204 rhombic 80° geometry
• Suited to aluminium and non-ferrous metals
• Cylindrical hole for secure mounting

High productivity from PCD technology

The use of polycrystalline diamond (PCD) in the DX140 grade delivers a combination of extreme wear resistance and consistent edge stability that directly increases machining throughput. PCD is a synthetic diamond layer sintered onto a carbide substrate; this structure provides superior abrasion resistance compared with conventional carbide grades, which means longer tool life and fewer indexings in serial production. For components made from aluminium or other non-ferrous alloys and abrasive composites, this results in reduced downtime and more predictable cycle times.

Secure fit and ISO-compatibility for reliable set-up

Compatibility with toolholders is determined by geometry, clearance and thickness. The insert follows the ISO CPGA090204 form, presenting an 80° rhombic shape, a 11° clearance angle and a plate thickness of 2.38 mm, which together ensure reliable seating in standard ISO holders. The cylindrical hole provides positive mechanical location and stable clamping, reducing the chance of insert movement under high cutting forces. Because these dimensions conform to ISO norms, integration into existing tool systems is straightforward and reduces the need for special adapters.

Consistent surface quality and process reliability

A PCD cutting edge delivers an excellent surface finish on light alloys by producing fine, short chips and limiting built-up edge. The DX140 grade is optimised for high-speed turning and maintains a sharp, durable cutting line even under abrasive conditions, supporting consistent dimensional accuracy and repeatable component quality. The carbide substrate under the diamond layer provides the rigidity needed for stability during feed changes and interrupted cuts, while the PCD face sustains low wear rates across long production runs.

Practical selection and system considerations

For general turning, a 0.4 mm corner radius offers a balance between edge strength and form fidelity; it resists chipping while still enabling fine profile work where small radii are required. Note that this insert is supplied without a chipbreaker, so chip control must be achieved via tooling geometry, feed selection and holder choice. A complete cutting system typically includes the ISO turning insert, a matching external holder or boring bar, a shim/clamping kit and replacement screws. When matching holders, ensure form, clearance, tolerance class, attachment and thickness are aligned with the ISO specification for dependable performance.

FAQ

What materials is this insert best suited for?
The CPGA090204 DX140 insert is designed for aluminium, other non-ferrous metals and abrasive non-metal materials; the PCD grade provides excellent wear resistance for these applications.

Is the insert compatible with standard ISO holders?
Yes. The insert follows the ISO CPGA090204 form with an 80° rhombic geometry, 11° clearance and a 2.38 mm thickness, allowing use in compatible ISO toolholders.

Why choose a 0.4 mm corner radius?
A 0.4 mm corner radius balances edge robustness and detail reproduction, offering resistance to chipping while still enabling accurate profiling in turning operations.

Does the insert include a chipbreaker?
This variant is supplied without a chipbreaker; chip control should be achieved through holder geometry, feed rate and process parameters.
