TPGW080204 DX140 – Tungaloy ISO turning insert, PCD grade for high‑speed aluminium turning

The TPGW080204 DX140 is a 60° triangular ISO turning insert designed for high‑speed machining of aluminium and other non‑ferrous and abrasive non‑metal materials, combining a polycrystalline diamond cutting layer with a carbide substrate for stable cutting performance.

• PCD cutting material for abrasive non‑ferrous alloys
• Long service life and high cutting speeds
• ISO triangular 60° form with 0.4 mm radius
• Cylindrical hole with one‑sided countersink

Higher productivity through PCD: faster cuts and far fewer tool changes

The use of polycrystalline diamond (PCD) as the cutting material gives a decisive productivity advantage when machining aluminium and abrasive non‑metals. PCD retains a keen edge at elevated cutting speeds, which means longer uninterrupted runs and fewer index changes. With a carbide substrate beneath the diamond layer, the insert delivers the rigidity required for stable turning, reducing cycle times while maintaining consistent dimensional accuracy and surface quality.

Predictable clamp security and precise geometry for repeatable results

The ISO‑standard triangular geometry with a 60° included angle and a 0.4 mm corner radius ensures reliable positioning in standard holders. The insert’s cylindrical hole with a one‑sided countersink (40°–60°) provides secure clamping and precise seating in most ISO‑compatible toolholders and boring bars. The 11° relief angle and 2.38 mm thickness contribute to contact stability; these measurable parameters simplify setup and reduce the risk of unexpected vibration or misalignment during turning.

Match grade and chipbreaker to the workpiece for best results

Selecting the right chipbreaker and the DX140 grade is essential for optimised results: the chipformer and grade should be chosen according to the workpiece material, the machining operation and the stiffness of the setup. A correctly matched chipbreaker improves swarf control and helps achieve consistent surface finish with fewer interruptions. The DX140 grade is configured for high cutting speeds and long life when machining non‑ferrous alloys and abrasive compounds, supporting lower overall tooling cost per component.

Practical system notes and workshop integration for dependable use

This insert is supplied as part of an ISO insert system: the complete setup comprises the triangular indexable insert, a matching external holder or boring bar, the appropriate shim/clamp set and replacement fastening screws. Compatibility is defined by insert form, relief angle, tolerance class, clamping type, size and thickness; verifying these parameters before purchase avoids installation delays. For workshop integration, the carbide substrate and PCD layer reduce the frequency of regrinding and extend productive tool life, supporting predictable maintenance intervals and lower overall process disruption.

FAQ

Which materials is this insert best suited for? The TPGW080204 DX140 insert is designed for aluminium, non‑ferrous alloys and abrasive non‑metal materials where PCD offers superior wear resistance and surface finish.

Why choose a PCD cutting material over conventional carbide? PCD provides a much harder cutting edge for non‑ferrous and abrasive workpieces; the DX140 grade combines PCD with a carbide substrate to deliver both edge life and the rigidity required for stable turning.

How does the insert secure in the holder? A cylindrical hole with a one‑sided countersink (40°–60°) and ISO triangular form ensure consistent seating and secure clamping in compatible holders and boring bars.

Can this insert be used for both external and internal turning? Yes, the geometry and hole style make the insert suitable for both external and internal turning when paired with the correct external holder or boring bar.

How to determine the correct chipbreaker and grade for a job? Choose the chipbreaker and grade according to the workpiece material, cutting operation and machine/fixture stability; for tailored recommendations, consult Metav Werkzeuge or refer to cutting data for the DX140 grade.
