TPGN 160308 DX140 Tungaloy indexable insert — for high-speed turning

TPGN 160308 DX140 is an ISO-format turning insert designed for high cutting speeds in non-ferrous materials and abrasive non-metals, supplied as a triangular, holeless insert for secure clamping in ISO holders.

• Polycrystalline diamond (PCD) grade DX140
• High cutting-speed capability for aluminium
• Triangle form with 60° included angle
• 0.8 mm corner radius for consistent profiles

High-speed performance that shortens cycle times

The PCD grade DX140 is engineered for high cutting speeds, delivering consistently long runtimes when machining aluminium and similar materials. With a diamond cutting layer on a carbide substrate, the insert provides a combination of wear resistance and toughness that reduces tool changes and keeps production lines moving. The result is a tangible increase in productivity through fewer interruptions and predictable tool life.

Geometry and edge condition that improve surface quality

The triangular insert with a 60° included angle and a 0.8 mm corner radius supports accurate profile generation and stable cutting forces during turning. The absence of an integrated chipbreaker directs process control towards stable cutting strategies for thin-walled workpieces and sections where chip control is managed by cutting parameters rather than geometry. This design helps produce improved surface finishes and repeatable component accuracy.

Compatibility and straightforward integration into ISO tool systems

As an ISO-standard insert, compatibility with external toolholders is determined by form, clearance angle, tolerance class, fastening and thickness; the 3.18 mm plate thickness and holeless design ensure a positive fit in appropriate clamping systems. The insert is intended to be used with a matching external holder or boring bar plus backing shim/clamp and replacement screws, enabling straightforward replacement and minimal set-up time on established turning centres.

Application benefits and recommended use cases

Designed specifically for turning operations in aluminium and other non-ferrous materials, this PCD insert excels in abrasive non-metals where elevated cutting speeds and tool life are decisive. The carbide substrate gives mechanical support for the diamond layer, maintaining edge strength under intermittent cuts. For stable setups and appropriate feeds, the insert offers long-term economy thanks to reduced tooling consumption and consistent part quality.

FAQ

What materials is this insert suitable for?
The TPGN 160308 DX140 insert is optimised for aluminium, non-ferrous metals and abrasive non-metals thanks to its PCD cutting layer and carbide backing.

Can this insert be used in standard ISO turning holders?
Yes, the insert follows ISO geometry and fits ISO-format external holders when matched by form, clearance angle and thickness; ensure the holder accepts a triangular, holeless insert.

Does the insert include a chipbreaker?
This grade is supplied without a chipbreaker, so chip control is managed via cutting parameters and holder orientation for the intended materials.

What edge preparations are available for consistent profiles?
The 0.8 mm corner radius provides a reliable profile edge for turning tasks requiring repeatable contours and improved surface quality.

How does the DX140 grade affect tool life?
DX140’s polycrystalline diamond structure offers very high wear resistance, which translates into extended tool life at elevated cutting speeds on suitable materials.
