CNGA 120404 DX140 Tungaloy indexable insert for Turning — PCD grade for aluminium

A CNGA 120404 DX140 indexable insert by Tungaloy, designed for precision turning of aluminium, non-ferrous and abrasive non-metallic materials

• PCD grade DX140 for aluminium & non-ferrous metals
• ISO-standard rhombic insert, 80° cutting edge
• 0° clearance for neutral cutting geometry
• Long tool life and high cutting speeds

High-speed aluminium turning with proven PCD advantages

The DX140 grade combines a polychrystalline diamond (PCD) cutting layer on a robust carbide substrate to provide exceptionally low wear when machining aluminium and similar materials. The abrasive resistance of PCD enables high cutting speeds and prolonged intervals between tool changes, which reduces downtime and increases throughput on production lathes. For jobs where surface finish and consistent dimensional accuracy matter, this geometry maintains a stable cutting edge and delivers a predictable result over long runs.

Seamless integration into ISO turning systems for flexible set-ups

As an ISO-conforming rhombic insert, the component fits standard holders when form, relief angle, tolerance class, fastening and thickness align. The rhombic plate with an 80° included angle gives a balance of edge strength and access to the workpiece, while the 0° clearance creates a neutral geometry suitable for a variety of turning tasks. Compatibility depends on the complete system: indexable insert, matching external holder or boring bar, support shim/ clamp set and replacement screws. Choosing the correct holder and clamping parts ensures repeatable seating and consistent process security.

Process stability, predictable wear and economic benefits

The absence of an integrated chipbreaker on this insert (chipbreaker: without) means chip control must be matched to the workpiece and cutting parameters; for many aluminium jobs the PCD surface promotes favourable chip formation and prevents built-up edge. The combination of a diamond cutting layer on a cemented base provides long tool life and reduced flank wear, cutting down tooling consumption and rework. For manufacturers seeking improved cycle times and constant surface quality, this solution reduces stoppages and supports a more economical production flow.

FAQ

What materials is this insert best suited for?
The CNGA 120404 DX140 Tungaloy insert is optimised for aluminium, other non-ferrous metals and abrasive non-metallic materials thanks to its PCD cutting layer.

Does the insert fit standard ISO holders?
Yes, the insert follows ISO indexable insert standards; fitment depends on matching form, relief angle, tolerance class, fastening, size and thickness to the chosen holder.

How does the lack of a chipbreaker affect machining?
Without an integrated chipbreaker, chip control must be achieved by selecting appropriate feeds, speeds and holder geometry; the DX140 PCD surface tends to promote clean chip formation on aluminium when parameters are set correctly.

What are the key dimensional data to check before ordering?
Refer to the size (12 mm), thickness (4.76 mm), corner radius (0.4 mm) and included angle (80°) to ensure compatibility with existing toolholders.
