TPGA 090204 DX140 Tungaloy ISO turning insert for turning

A TPGA090204 DX140 Tungaloy indexable insert engineered for high‑speed external and internal turning of aluminium and other non‑ferrous materials.

• PCD grade DX140 for aluminium and non‑ferrous metals
• ISO triangular insert TPGA090204
• Very long tool life at high cutting speeds
• 0.4 mm corner radius, 11° relief angle

High‑speed machining with PCD for consistent results

The insert uses polycrystalline diamond (PCD) in the DX140 grade, optimised for machining aluminium and abrasive non‑ferrous materials. The diamond cutting layer delivers superior wear resistance, which translates into longer tool life and fewer interruptions for index changes. For production environments where cycle time and surface integrity matter, the PCD edge enables higher cutting speeds and a lower cost per component when compared with conventional coatings.

Stable geometry and ISO conformity for reliable clamping

The TPGA090204 format follows ISO conventions for triangular turning inserts, ensuring compatibility with a wide range of holders when form, clearance, tolerance class, fastening method, size and thickness match. The triangular shape combined with a 0.4 mm corner radius and 11° relief angle offers good edge strength and predictable chip formation. The insert’s cylindrical hole and standard dimensions simplify fixture selection and reduce setup time on production lines.

Productivity gains through reduced tool changes

Selecting a DX140 PCD grade minimises downtime caused by frequent insert replacements. The combination of long stand life and thermal stability supports uninterrupted runs and fewer tool inventories. In practical terms this means lower handling effort, improved machine uptime and a better output per shift — particularly important in batch production and automated turning centres where consistent tool performance is essential.

Practical application notes and handling

Designed for turning operations, the insert is suitable for both external and internal applications when matched with an appropriate carbide or steel holder. As the insert lacks an integrated chipbreaker, choose a holder and cutting parameters that support controlled chip evacuation for the specific non‑ferrous alloy. For material‑specific recommendations and parameter windows, contact the technical advisors at Metav Werkzeuge or consult the Tungaloy product literature for best‑practice cutting data.

FAQ

What materials is this insert best suited for?
The TPGA090204 DX140 is designed primarily for aluminium and other non‑ferrous metals; the PCD cutting layer ensures long life when machining abrasive non‑metallic materials too.

Is the insert compatible with standard ISO TPGA toolholders?
Yes — the TPGA090204 follows ISO dimensions; compatibility is determined by the holder’s form, clearance, tolerance class, fastening method, size and thickness.

Does this grade include a chipbreaker?
No, this insert is supplied without a chipbreaker; chip control depends on holder geometry and cutting parameters.

What benefits does the DX140 grade provide over coated carbide inserts?
DX140’s PCD edge offers markedly better wear resistance and allows higher cutting speeds, resulting in fewer tool changes and improved productivity in non‑ferrous turning.

Can this insert be used for internal boring operations?
Yes — when installed in a suitable boring bar or internal holder that matches the ISO dimensions, the insert performs well in internal turning of aluminium and similar materials.
