TPGW16T302 DX140 – Indexable turning insert for high-speed aluminium turning | Tungaloy

A TPGW16T302 DX140 indexable turning insert engineered for fast turning of aluminium, non-ferrous metals and abrasive non-metals, offering sustained performance in ISO-standard turning systems

• PCD grade DX140 for aluminium machining
• ISO-standard triangle insert, 60° geometry
• Long tool life and high cutting speeds
• Cylindrical hole with 40°–60° countersink

High-speed aluminium turning with PCD for increased productivity

The PCD cutting structure, designated DX140, is optimised for machining aluminium and other non-ferrous materials at elevated cutting speeds while delivering long tool life and consistent edge quality. Polycrystalline diamond (PCD) is a superhard cutting material that provides excellent abrasion resistance and extremely low flank wear on soft, abrasive workpieces; this reduces the frequency of insert changes and minimises unplanned downtime. Specifying a PCD grade such as DX140 supports more productive cycle times and predictable process windows, which is particularly advantageous in high-volume components and finishing operations.

Precise ISO geometry for stable cuts and predictable results

The insert’s triangular 60° geometry, combined with a 0.2 mm corner radius and an 11° relief angle, creates a stable cutting edge that balances strength and form accuracy. A thickness of 3.97 mm increases rigidity in the clamping area, reducing vibration during turning operations and improving surface finish. The central hole with cylindrical bore and single-side countersink (40°–60°) ensures reliable clamping in compatible holders; correct clamping eliminates micro-movement under load and preserves the integrity of the PCD edge, translating into repeatable component quality and reduced rework.

System compatibility and application guidance for efficient integration

This indexable insert is part of an ISO-standard turning insert series and is designed to work within a system consisting of a matching external holder or boring bar, shim/clamping kit and replacement fastening screws; compatibility depends on form, relief angle, tolerance class, fastening style, size and thickness. The insert is supplied without an integrated chipbreaker, so selection of the appropriate cutting geometry and cutting parameters is essential for chip control in specific turning tasks. Typical uses include external and internal turning where DX140 PCD excels on aluminium, non-ferrous alloys and abrasive non-metals, offering a balance of speed and longevity for production and finishing operations.

FAQ

Is this insert suitable for hardened steels?
No. The TPGW16T302 DX140 insert is intended for aluminium, non-ferrous metals and abrasive non-metals; it is not designed for machining hardened steels.

What does the absence of a chipbreaker imply for machining?
An insert without a chipbreaker, such as this DX140 variant, requires appropriate cutting conditions and toolholder geometry to achieve effective chip control during turning.

Can the insert be used in internal and external turning operations?
Yes. The ISO-design insert is suitable for both external and internal turning when combined with a compatible holder and correct setup.

How does the 0.2 mm corner radius affect surface finish?
A 0.2 mm corner radius provides a compromise between edge strength and fine surface finish; it helps maintain part geometry and reduces burr formation on aluminium components.

Which holding features ensure secure clamping?
The cylindrical central hole with a single-side countersink (40°–60°) and the specified thickness and relief angle support reliable clamping in compatible holders
