SPGN 120304 DX140 — SPGN120304-DIA ISO turning insert (Turning) by Tungaloy

The SPGN120304-DIA is an ISO-format indexable insert designed for high-speed turning of aluminium, non-ferrous alloys and abrasive non-metallic materials, delivering long tool life and consistent chip control in production environments.

• High-speed PCD cutting performance
• Exceptional tool life on aluminium
• ISO-compatible square 12 mm form
• Carbide substrate with DX140 grade

High-speed turning with durable PCD technology

The incorporation of polycrystalline diamond (PCD) cutting material in the DX140 grade enables significantly higher cutting speeds when machining aluminium and abrasive non-metals, while maintaining a stable cutting edge. The benefit is reduced cycle times and extended tool life compared with conventional grades, which translates into fewer interruptions for tool changes and a more predictable production rhythm. PCD is particularly effective on non-ferrous alloys because it resists abrasive wear and preserves geometry under thermal and mechanical load.

Compatible ISO geometry for simple system integration

The square plate geometry with a nominal size of 12 mm and an included angle of 90° ensures straightforward compatibility with ISO-standard toolholders. Fit is determined by form, relief angle, tolerance class, fastening method, size and thickness; the insert's 3.18 mm plate thickness and square format make it suitable for common ISO holders designed for external and internal turning. This standard conformity reduces setup complexity and enables quick insertion into existing tool systems without the need for bespoke adapters.

Robust substrate and chip control for consistent surface quality

A carbide substrate beneath the PCD layer provides mechanical support and damping, improving resistance to fracture under interrupted cuts. The DIA chipbreaker is optimised for aluminium and similar materials, producing controllable chip forms and reducing the risk of recutting. The combined effect is a reliable surface finish and fewer scrap parts, which supports stable process quality and predictable machining outputs in serial production.

Practical selection guidance for production use

When selecting an insert for a given application, match the DX140 grade and DIA chipbreaker to component material, machining strategy and machine-tool rigidity. The 11° clearance angle promotes efficient cutting with reduced rubbing, while a 0.4 mm corner radius balances edge strength and achievable surface finish. For best results, pair the insert with a rigid holder and adapt cutting parameters to exploit PCD's high-speed capability; modest increases in cutting speed often yield disproportionate reductions in cycle time when stability is sufficient.

FAQ

What materials is this insert best suited for?
The SPGN120304-DIA insert with DX140 PCD is optimised for aluminium, other non-ferrous metals and abrasive non-metallic materials where high cutting speed and long tool life are priorities.

How does the PCD layer affect performance compared with conventional grades?
A PCD cutting layer on a carbide substrate provides superior wear resistance and thermal stability, so the DX140 grade maintains edge sharpness longer and enables higher cutting speeds than standard carbide grades.

Is the SPGN120304-DIA compatible with standard ISO toolholders?
Yes; the insert follows ISO geometry (square 12 mm, 90° included angle) and is compatible with holders that match the form, relief, tolerance, fastening and thickness specifications for ISO-format inserts.

Which chipbreaker should be selected for aluminium turning?
The DIA chipbreaker supplied with this insert is designed for aluminium and similar materials, offering controlled chip formation and reliable evacuation under high-speed conditions.

What dimensional data are decisive when selecting the right holder?
Key dimensions are plate size (12 mm), plate thickness (3.18 mm), corner radius (0.4 mm) and clearance angle (11°); these determine the suitable holder form and clamping arrangement for safe, repeatable use.
