TPGA160302 DX140 — TPGA triangular turning insert, PCD grade (Tungaloy)

The TPGA160302 DX140 is a triangular ISO turning insert designed for high‑speed machining of aluminium, non‑ferrous metals and abrasive non‑metallic materials.

• PCD grade DX140 for high wear resistance
• Optimised for high cutting speeds
• ISO triangular shape, 60° included angle
• Compatible with ISO turning holders

Consistent high performance for aluminium and non‑ferrous machining

The TPGA160302 DX140 combines a polycrystalline diamond (PCD) cutting layer with a robust carbide body to deliver very low flank wear when machining abrasive or non‑ferrous materials. The PCD grade DX140 is engineered for high cutting speed applications and preserves edge sharpness over extended production runs, which reduces the frequency of index changes and boosts process uptime. This makes the insert particularly suited to long series where surface finish and repeatability matter.

Straightforward integration into ISO turning systems

With an ISO TPGA geometry and a 60° included angle, the insert fits standard ISO turning holders provided form, clearance angle, tolerance class, clamping method, size and thickness match the holder specifications. The combination of a triangular shape and a corner radius 0.2 mm allows secure clamping and predictable chipflow for external and internal turning operations. Compatibility with common holder styles simplifies tool assortment and shortens setup time on the shop floor.

Practical benefits: economy and predictability

Using a PCD‑tipped insert such as this reduces unplanned downtime thanks to long tool life and stable wear behaviour; one or two tool changes per batch can often replace multiple carbide inserts under similar cutting conditions. The 3.18 mm plate thickness provides adequate mechanical support for the PCD layer while maintaining a compact insert package that minimises overhang and vibration for improved surface quality.

Application guidance and selection tips

Select the DX140 grade and an appropriate chipformer based on workpiece material, cutting parameters and machine rigidity. Although this insert is supplied without a chipbreaker, pairing it with the correct feed and depth of cut yields controlled chips and consistent results in aluminium and other non‑ferrous alloys. Where holder compatibility is uncertain, verify form and clamping details against the ISO standard to ensure safe, repeatable operation.

FAQ

What materials is this insert best suited for?
The TPGA160302 DX140 insert is optimised for aluminium, non‑ferrous metals and abrasive non‑metallic materials thanks to its DX140 PCD cutting layer and carbide support.

Does the insert require a specific holder type?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the TPGA160302 follows ISO geometry and is intended for ISO turning holders meeting those specifications.

Is a chipbreaker included with the insert?
This variant is supplied without a chipbreaker; chip control is achieved through appropriate feeds, depths of cut and holder selection.

What advantages does the DX140 grade offer over conventional carbide tips?
DX140 PCD provides higher wear resistance and extended service life at high cutting speeds, which improves process stability and reduces tool change frequency in suitable materials.
