TPGW090204 DX140 Tungaloy turning insert — PCD grade for high‑speed aluminium turning

A TPGW090204 DX140 indexable insert engineered for external and internal turning of aluminium, non‑ferrous metals and abrasive non‑metallic materials.

• PCD grade DX140 for aluminium and non‑ferrous
• ISO triangular form TPGW090204, 60° included angle
• Excellent wear resistance for long runtimes
• Carbide body with polycrystalline diamond cutting edge
• Cylindrical hole with single‑side countersink 40°–60°

Boosted productivity for aluminium and non‑ferrous components

The DX140 cutting grade combines a polycrystalline diamond (PCD) cutting edge with a robust carbide body to enable consistently high cutting speeds and markedly extended service intervals. This composition reduces flank wear and abrasion when machining soft, gummy materials such as aluminium alloys and other non‑ferrous metals, as well as abrasive composites. The outcome is fewer insert changes, reduced downtime and a more economical machining cycle — tangible productivity gains for medium‑ to high‑volume production.

Smooth integration with ISO tooling systems

Compliance with the ISO designation makes mounting and replacement predictable: the triangular geometry with a 60° included angle and the standard bore arrangement ensures compatibility with a wide range of ISO toolholders. The insert’s fit is defined by form, clearance angle, tolerance class, fastening, size and thickness; the 11° clearance and 2.38 mm plate thickness support stable clamping and heat dispersion during sustained cutting. This standardisation simplifies tooling logistics and shortens setup times on the shop floor.

Precise geometry for fine surface quality and repeatability

A corner radius of 0.4 mm provides a balance between strength and the ability to achieve good surface finish on turned parts. The absence of a chipbreaker means the cutting action relies on the tool geometry and machining parameters; selecting feeds and speeds appropriate for the material and machine stiffness produces controlled chip formation and consistent edge life. The insert is suited to both external and internal operations when paired with the correct holder, shim and clamping set as part of the ISO insert system.

Material details and recommended applications

Constructed with a carbide substrate and a PCD cutting layer in DX140 grade, the insert is intended for turning tasks where high wear resistance and excellent edge retention are required. Typical uses include finishing and semi‑finishing aluminium components, machining of non‑ferrous alloys and certain abrasive non‑metallic workpieces. The system approach — insert, matching holder or boring bar, backing shim and clamping kit — ensures repeatable mounting and secure fixation under the forces encountered during high‑speed cutting.

FAQ

What materials is this insert suitable for?
The TPGW090204 DX140 insert is designed for aluminium, other non‑ferrous metals and abrasive non‑metallic materials; the PCD cutting edge in DX140 grade gives high wear resistance and long life when machining such materials.

Does this insert fit standard ISO holders?
Yes, the insert follows the ISO TPGW090204 specification; compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness of the holder assembly.

Is there a chipbreaker on the insert?
No, this insert is supplied without a chipbreaker; chip formation is managed through correct selection of feed, speed and holder geometry for the workpiece.

What is the corner radius and why does it matter?
The corner radius is 0.4 mm; this radius offers a compromise between edge strength and the ability to achieve good surface finish, particularly important for finishing passes on aluminium components.

Can the insert be used for both external and internal turning?
Yes, the insert is suitable for external and internal turning when paired with an appropriate holder or boring bar and correct clamping elements.
