High‑speed aluminium turning with PCD performance

The combination of a polycrystalline diamond (PCD) cutting edge and the DX140 grade is engineered for demanding aluminium and non‑ferrous applications. PCD delivers extremely low flank wear at elevated feeds and high cutting speeds, reducing cycle times while maintaining surface integrity. This makes the insert particularly suited to abrasive non‑metal materials where conventional coatings wear quickly. The substrate is carbide, providing mechanical support for the diamond layer and reliable edge stability during interrupted cuts.

Predictable wear behaviour that increases uptime

A consistent wear curve from the diamond surface results in long tool life and stable chip formation, which together lower the cost per finished part and reduce spindle downtime. The economic advantage is tangible in high‑volume production: fewer indexings and insert changes translate into shorter non‑productive intervals. When compared with coated carbide solutions in the same family of applications, the PCD grade often demonstrates a superior life‑time profile, especially under conditions of elevated cutting speed and abrasive workpiece materials.

Clear ISO compatibility for straightforward tool setting

This is an ISO‑standard insert supplied in a square form with a nominal size of 12 mm, a plate thickness of 3.18 mm and a 0.2 mm corner radius; the 11° clearance angle and 90° lead angle are stated for correct holder selection. Compatibility with toolholders is determined by form, clearance, tolerance class, fixing method, size and thickness; a typical system comprises an ISO insert, a matching external holder or boring bar, a shim/clamp set and fastening screws. Using standardised dimensions simplifies inventory management and ensures quick changeover between tool assemblies.

Chip control and application guidance for reliable results

The chipbreaker DIA geometry is tailored to evacuate swarf efficiently in aluminium and similar materials, avoiding re‑cutting of chips and reducing the risk of built‑up edge. Selection of chipbreaker and grade should match material, machining type and machine stability: for high feed finishing, a small radius provides improved profile accuracy; for roughing, a slightly larger nose radius can enhance strength. The insert is suitable for both external and internal turning operations when paired with the appropriate holder and clamping hardware.

FAQ

What materials is this insert designed for?
The SPGN120302‑DIA DX140 Tungaloy insert is designed primarily for aluminium, non‑ferrous metals and abrasive non‑metal materials, taking advantage of the PCD cutting edge for high‑speed performance.

Which chipbreaker is fitted and what is its effect?
The insert uses the DIA chipbreaker, optimised for controlled chip formation in soft to abrasive non‑metallic materials and non‑ferrous alloys, improving surface finish and swarf evacuation.

How does the DX140 grade influence machining?
The DX140 grade provides a wear‑resistant PCD layer that enables elevated cutting speeds and long tool life in suitable applications, lowering the frequency of insert changes in production.

Is this insert compatible with standard ISO toolholders?
Yes, the insert is an ISO‑standard type; compatibility depends on form, size, thickness and fixing method, so matching the 12 mm square form and 3.18 mm thickness to the correct holder is essential.

What are the key dimensions to check before mounting?
Check the 12 mm nominal size, 3.18 mm thickness, 0.2 mm corner radius and the 11° clearance angle to ensure correct seating and clamping in the toolholder.
