DCGW070204 DX140 Tungaloy indexable insert for ISO turning — PCD grade for aluminium

DCGW070204 DX140 Tungaloy-Wendeplatte is an ISO-standard indexable insert intended for high-speed turning of aluminium and other non-ferrous materials

• PCD grade DX140 for high cutting speeds
• ISO rhombic insert with 55° cutting angle
• Suitable for aluminium and non-ferrous metals
• Cylindrical hole with 40°–60° countersink

Faster cycle times through advanced PCD grade

The DX140 polycystalline diamond (PCD) cutting layer delivers very high wear resistance and enables high cutting speeds, particularly when machining abrasive non-ferrous materials. For production runs where reduced tool change frequency matters, the PCD topology provides long tool life, which translates into fewer interruptions and a lower cost per part. The combination of a hard PCD face and a carbide substrate results in consistent performance under continuous cutting, maintaining dimensional stability and predictable tool-change intervals.

Reliable fit and geometry for consistent results

Designed as an ISO-standard indexable plate, the insert features a rhombic form and a 55° cutting angle that suit a broad range of external and internal turning operations. The 7° relief angle reduces flank rubbing and helps extend edge life in finishing passes, while the 0.4 mm nose radius supports precise contouring and repeatable surface quality. The plate thickness of 2.38 mm and standard mounting interface — a cylindrical hole with a one-sided countersink (40°–60°) — ensure compatibility with common holders when form, clearance angle, tolerance class, fastening and size are matched.

Optimised for aluminium and non-ferrous alloys

This indexable insert excels on aluminium and other non-ferrous materials where PCD provides superior abrasion resistance and excellent thermal stability at high speeds. The absence of an integrated chipbreaker means the cutting strategy should be matched to material feed and toolholder rigidity; when paired with an appropriate chip control geometry and stable tooling setup, the insert delivers fine surface finish and minimal secondary operations. For abrasive non-metals or filled composites, the PCD grade reduces edge wear compared with conventional carbide tips, improving overall process efficiency.

Practical handling, mounting and productivity advice

The insert is supplied in the ISO DCGW format with the designation 070204 and is intended to be used with a compatible external holder or boring bar plus correct clamping pads and screws. The rhombic shape and central hole with countersink simplify positioning and torque transfer while maintaining repeatable indexability. For best results, select holder rigidity and cutting parameters that exploit the PCD’s high-speed capability; this approach maximises productivity and reduces per-piece machining costs without compromising component accuracy.

FAQ

Which materials is this insert suitable for?
The DCGW070204 DX140 insert is engineered for aluminium and other non-ferrous metals; the PCD cutting face provides wear resistance on abrasive non-metals.

Is the insert compatible with standard ISO holders?
Yes, the ISO-format DCGW070204 geometry ensures compatibility where holder form, relief angle, tolerance and fastening match the plate size and thickness.

What are the main benefits of the DX140 PCD grade?
DX140 offers high cutting speeds and extended edge life compared with conventional carbide tips, improving productivity and reducing tool-change frequency in suitable applications.

Does this insert include a chipbreaker?
This plate is supplied without a chipbreaker, so chip control should be achieved through cutting data, holder geometry and process parameters.

What are the key dimensional details to check when fitting?
Verify the central hole, one-sided countersink, plate thickness (2.38 mm), nose radius (0.4 mm) and the 55° cutting geometry for correct seating and repeatable clamping.
