TPGW090202 DX140 — Tungaloy ISO triangular PCD turning insert for turning

A TPGW090202 DX140 ISO-format triangular turning insert engineered for high-speed machining of aluminium, non-ferrous and abrasive non-metals.

• PCD grade DX140 for aluminium machining
• Triangular 60° geometry for stable turning
• 0.2 mm corner radius for fine finishes
• Compatible with ISO turning holders

High-speed machining with fewer tool changes

The insert combines a polycystalline diamond (PCD) cutting material in grade DX140 with an ISO triangular form to enable high cutting speeds and long tool life when machining aluminium and similar alloys. The PCD microstructure is optimised for abrasive, non-ferrous materials, which results in reduced flank wear and a lower replacement frequency. This technical advantage leads to measurable improvements in uptime and a lower cost per finished part, particularly in high-volume external and internal turning operations.

Geometry designed for consistent surface quality

The triangular 60° geometry and a precisely formed 0.2 mm corner radius deliver repeatable engagement and a controlled cutting edge, which supports consistent surface finish and dimensional stability. With a plate thickness of 2.38 mm, the insert provides sufficient bulk for secure clamping while maintaining the small edge condition needed for fine finishing work. The insert is supplied without an integrated chipbreaker, which is appropriate for many aluminium applications where chip form is managed by geometry and cutting parameters.

System compatibility and secure clamping

The product is part of an ISO insert system and is intended to be used with a suitable external holder or boring bar, together with a matching shim or clamping set and replacement screws. Compatibility with a holder is determined by the insert form, clearance angle, tolerance class, method of fixation, size and thickness. The plate is supplied with a cylindrical hole plus a single-side countersink (40°–60°), facilitating accurate location and a secure clamp when mounted in standard ISO toolholders.

Application range and process benefits

Designed for turning, this insert is particularly suited to aluminium, non-ferrous metals and abrasive non-metals, where PCD cutting edges offer superior wear resistance and consistent edge integrity. The combination of material and geometry supports stable cutting conditions, shortened setup intervals and predictable tool life. For production environments prioritising throughput and surface quality, the result is a more reliable machining process and reduced secondary finishing.

FAQ

What materials is this insert suitable for?
The TPGW090202 DX140 insert is intended for aluminium, non-ferrous metals and abrasive non-metals; the DX140 PCD grade is optimised for long life under these conditions.

Is the insert compatible with standard ISO turning holders?
Yes. The insert follows ISO form and is compatible when the holder matches form, clearance angle, tolerance class, fixation method, size and thickness.

How does the hole and countersink affect mounting?
The cylindrical hole with a single-side countersink (40°–60°) provides positive location and secure clamping in standard ISO clamping systems.

Can this insert be used for internal turning as well as external?
Yes. The geometry and PCD grade permit both external and internal turning operations, provided a suitably sized holder or boring bar is used.

What performance improvements are expected with the DX140 grade?
The DX140 PCD cutting material typically yields higher cutting speeds and extended tool life in suitable materials, reducing downtime for insert changes and improving process stability.
