TNGA 160404 DX140 TNGA160404 turning insert by Tungaloy — PCD grade for turning

A TNGA160404 DX140 indexable turning insert designed for high-speed external and internal turning of aluminium, non-ferrous metals and abrasive non-metallic materials.

• TNGA geometry ISO 160404 compatible
• PCD grade DX140 for high-speed machining
• Long tool life and abrasion resistance
• Triangle insert, 60° with cylindrical hole

High cutting performance and predictable economy

The diamond cutting layer of PCD in the DX140 grade delivers significantly improved wear resistance and consistent edge integrity in the machining of aluminium and other non-ferrous materials. This enables substantially higher cutting speeds compared with conventional coatings, which shortens cycle times and reduces per-part tooling costs. For operations involving abrasive non-metals, the PCD edge maintains form and surface finish far longer than uncoated alternatives, supporting predictable machining windows and fewer tool changes.

Geometry and compatibility that simplify setup

The insert follows the ISO 160404 format and a TNGA geometry, with a 60° triangle form and a corner radius of 0.4 mm. The relief angle is 0°, and the plate thickness is 4.76 mm, with a central cylindrical hole for secure clamping. These attributes make the insert compatible with standard ISO holders when matched by form, tolerance class, screw size and seating. Because the grade is supplied without a dedicated chipbreaker, pairing with the correct holder and external chip control measures is advised to achieve consistent chip formation and stable cutting.

Substrate, surface quality and process benefits

A robust cemented carbide substrate supports the PCD cutting layer, combining toughness with the abrasion resistance of diamond for extended tool life. The result is improved surface finishes and reduced burr formation on machined non-ferrous parts, which lowers downstream rework. Stable chip formation and reduced vibration contribute to repeatable dimensional results and less machine downtime. Selecting DX140 for medium to high stability setups yields especially good productivity gains; in less rigid conditions, slower feeds or adapted clamping are recommended to preserve edge life.

FAQ

What materials is this insert optimised for?
The TNGA160404 DX140 indexable insert is optimised for aluminium, other non-ferrous metals and abrasive non-metallic materials thanks to its PCD cutting layer.

How does the DX140 grade affect productivity?
The DX140 grade provides high wear resistance and enables higher cutting speeds, which improves cycle times and reduces tooling changes for many non-ferrous turning tasks.

Is a specific holder required for this insert?
Compatibility depends on holder form, relief angle, tolerance class and fastening; the TNGA160404 format fits ISO holders that match the TNGA geometry and central clamping arrangement.

Does the insert include a chipbreaker?
This grade is supplied without a chipbreaker; chip control should be achieved via holder design or external measures to ensure stable chip evacuation.

What is the Manufacturer article number and SKU?
Manufacturer article number 6808089 and manufacturer SKU TUN6808089 identify the Tungaloy TNGA160404 DX140 indexable insert.
