Maximise productivity with high‑speed PCD performance

The combination of polycrystalline diamond (PCD) cutting material and a carbide substrate delivers a step change in machining aluminium and abrasive non‑ferrous materials. The DX140 grade is developed for stable cutting at elevated speeds, which translates into shorter cycle times and reduced abrasive wear. Where conventional carbide grades blunt rapidly, PCD maintains a sharp edge longer, significantly lowering the frequency of insert changes and associated downtime. For batch production and high‑volume turning, this results in a clear economic advantage through increased spindle uptime and improved process reliability.

Reliable integration through ISO conformity and precision geometry

ISO standardisation of the insert designation guarantees straightforward selection of compatible holders when size, thickness and clamping style match. The square plate geometry with a 90° included angle offers flexibility for both facing and shoulder turning operations, while the 0.8 mm corner radius supports clean edge formation and consistent surface finish on profiles. The 3.18 mm plate thickness provides mechanical stability under moderate to high cutting loads, and the absence of a chipbreaker simplifies chip behaviour considerations when cutting ductile materials such as aluminium alloys. Compatibility depends on form, clearance angle, tolerance class, clamping and size, so confirm holder matching to secure repeatable set‑ups.

Reduce total machining cost with longer life and predictable results

Adopting a PCD solution such as the DX140 grade reduces total cost per part by extending the period between tool changes and by stabilising surface quality over long runs. Fewer tool interventions reduce handling errors and increase process consistency, which is especially beneficial in serial production and CNC‑based workflows. The insert’s design supports both external and internal turning applications and is suited to operations where high cutting speeds and abrasion resistance are priorities. For workshops seeking to improve throughput and process predictability, this grade offers a pragmatic route to higher productivity without complex rework of machining programs.

FAQ

What materials is this insert suited for?
The SPGN120308 DX140 Tungaloy insert is intended primarily for aluminium and other non‑ferrous and abrasive non‑metallic materials, exploiting the abrasion resistance of the PCD cutting material.

Can the insert be used for internal as well as external turning?
Yes, the ISO square geometry and the 90° included angle allow the insert to be used for both external and internal turning operations when mounted in a suitable holder.

How does the DX140 grade affect cutting speed and tool life?
The DX140 PCD grade enables higher cutting speeds and extended tool life compared with conventional carbide grades, reducing tool changes and improving overall machining efficiency.

Which holders are compatible with this ISO designation?
Compatibility with holders depends on form, clearance angle, tolerance class, clamping method, size and thickness; confirm these parameters to ensure proper fit for SPGN120308.

What are the key dimensional specifications to check before ordering?
Verify thickness (3.18 mm), corner radius (0.8 mm), plate size (12 mm) and included angle (90°) to ensure the insert matches the intended holder and machining task.
