VCGW 160404 DX140 indexable insert — PCD grade DX140 for high-speed turning by Tungaloy

VCGW160404-DIA DX140 is an ISO-standard indexable insert designed for external and internal turning of aluminium and other non-ferrous materials, offering long tool life and high cutting speeds.

• PCD grade DX140 for long tool life
• High cutting speeds for aluminium machining
• Rhombic 35° geometry for versatile turning
• Cylindrical hole with countersink for secure clamping

High-speed cutting and extended service life for non-ferrous materials

This insert uses polycrystalline diamond (PCD) in the DX140 grade, specifically engineered for machining aluminium, other non-ferrous metals and abrasive non-metals. The diamond cutting structure provides a markedly longer tool life than conventional carbide when used in the intended applications, reducing tool change frequency and improving process economy. The design supports high cutting speeds, which shortens cycle times on suitable machines while maintaining consistent edge integrity and predictable wear behaviour.

ISO compatibility and secure mechanical interface for reliable clamping

The insert conforms to ISO dimensions and must be matched to an appropriate holder based on shape, relief angle, tolerance class, attachment, size and thickness. The rhombic form with a 35° approach angle delivers flexible geometry for both profiling and turning operations. A 0.4 mm corner radius helps to balance edge strength and surface finish. The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) for dependable clamping; this arrangement reduces micro-movement under cutting loads and supports repeatable positioning in production tooling systems.

Operational advantages: surface quality and process stability

When used for external and internal turning, this PCD solution contributes to improved surface finish and consistent dimensional accuracy on soft to abrasive non-ferrous components. The low wear rate of the diamond cutting edge maintains cutting geometry over longer intervals, which translates into fewer interruptions and predictable batch throughput. Selecting the correct chipbreaker and the DX140 grade helps to control chip form and to maintain process stability across varying material conditions and machine rigidities.

Practical guidance for selection and machine setup

Choose holders and clamping sets compatible with ISO indexable inserts and ensure a rigid setup to fully leverage the high cutting speed capability. The insert’s substrate is a hard material combined with the PCD cutting element; handle inserts carefully to avoid chipping at the cutting edge and to preserve the diamond surface. For optimum results, match feed and speed to the workpiece alloy and the intended finish; in many aluminium applications this insert enables aggressive material removal while keeping tool consumption low. Manufacturer references and item codes are available for procurement and inventory management.

FAQ

What materials is this insert best suited for?
The VCGW160404-DIA DX140 insert is designed for aluminium, non-ferrous metals and abrasive non-metallic materials; the PCD cutting structure of the DX140 grade enables high cutting speeds and extended tool life in these applications.

How does the insert attach to a holder?
The insert uses a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness.

What are the key dimensions to check when selecting a holder?
Check the ISO designation (160404), size 16, thickness 4.76 mm, corner radius 0.4 mm, relief angle 7° and the rhombic shape to ensure a precise fit with the chosen holder.

Can this insert be used for internal turning?
Yes, the geometry and rhombic 35° approach angle make the insert suitable for both external and internal turning when paired with an appropriate holder and stable setup.

Is DX140 suitable for high material removal rates?
DX140’s PCD cutting structure supports high cutting speeds and is often used where high material removal and long tool life are required on non-ferrous alloys.
