DCGW070202 DX140 turning insert (Tungaloy) — PCD grade for aluminium and non-ferrous materials

The DCGW070202 DX140 is an ISO-standard indexable turning insert designed for external and internal turning of aluminium, non-ferrous alloys and abrasive non-metals, offering high-speed capability and durable wear resistance.

• PCD grade DX140 for high cutting speeds
• ISO rhombic 07 form, 55° cutting geometry
• Cylindrical hole with single-sided countersink
• Very long tool life and abrasion resistance

Higher throughput with polycrystalline diamond technology

The core advantage of this indexable insert is the polycrystalline diamond (PCD) cutting material in grade DX140, which enables substantially increased cutting speeds when machining aluminium and other non-ferrous alloys. PCD provides a very hard, wear-resistant cutting edge that reduces flank wear and maintains a consistent cutting geometry over prolonged runs. For production environments this translates into fewer tool changes and more parts produced per shift, directly improving process efficiency and reducing downtime.

Reliable clamping and stable machining results

Secure fixation is ensured by the cylindrical hole with a single-sided countersink (40°–60°), designed to match standard ISO-compatible holders. The insert’s rhombic 07 shape and 55° cutting angle deliver predictable chipflow and accessibility in both external and internal turning. Compatibility with a holder depends on the insert’s form, clearance angle, tolerance class, fastening method, size and thickness; these parameters allow integration into existing tool systems with consistent repeatability and minimal set-up time.

Predictable surface quality and application fit

The 0.2 mm corner radius and the PCD cutting edge combine to produce fine surface finishes on aluminium and similar materials while tolerating abrasive constituents better than conventional carbide grades. Because the DX140 grade is optimised for non-ferrous and abrasive non-metals, the insert supports a broad range of applications where both high metal removal rates and good finish are required. For customers less familiar with diamond tooling, PCD can be understood as a bonded diamond layer on a supporting substrate that removes material mechanically rather than through thermal softening.

Practical integration and handling for production use

The insert’s 2.38 mm thickness and ISO designation 070202 facilitate straightforward inventory management and replacement. The absence of a built-in chipbreaker in this design means process parameters—feed, depth of cut and cutting speed—should be matched to the workpiece and machine rigidity for optimal chip control. The system build typically includes the ISO indexable insert, a matching external holder or boring bar, a locating pad or clamp set and replacement screws, ensuring an all-round approach to installation and maintenance planning.

FAQ

What materials is this insert best suited for?
The DCGW070202 DX140 insert uses a PCD cutting material in grade DX140, making it particularly suited for aluminium, other non-ferrous alloys and abrasive non-metallic materials.

How does the insert secure in the holder?
Clamping is provided via the cylindrical hole with a single-sided countersink (40°–60°); when combined with an ISO-compatible holder and correct clamp set, the insert offers stable fixation and repeatable positioning.

Is a chipbreaker included with this insert?
This insert is supplied without a chipbreaker, so chip control should be achieved by selecting appropriate cutting parameters and tooling strategy for the application.

What practical benefits does the DX140 grade deliver on the shop floor?
DX140’s diamond cutting edge offers extended tool life and high cutting speeds on non-ferrous materials, reducing tool change frequency and increasing net machining time.
