TNMM 160404 DX120 — Tungaloy indexable turning insert, PCD, 60°

TNMM 160404 DX120 is an ISO‑standard triangular indexable insert designed for high‑speed external and internal turning of aluminium, non‑ferrous metals and abrasive non‑metallic materials.

• Polycrystalline diamond (PCD) cutting edge
• Triangular 60° geometry for versatile turning
• 0.4 mm corner radius for fine profile control

High‑speed performance and long tool life

The polycrystalline diamond grade DX120 offers exceptional wear resistance and thermal stability, enabling much higher cutting speeds than conventional carbide grades when machining non‑ferrous materials. Thanks to the PCD cutting layer, the insert sustains consistent edge geometry over long production runs, which reduces downtime for tool changes and maintains surface integrity on workpieces. This results in measurable productivity gains and less frequent re‑grinding in continuous turning operations.

Precise geometry for reliable finishes

The triangular 60° shape combined with a 0.4 mm corner radius provides stable cutting engagement and predictable chip formation for profile and detail work. The insert’s 0° relief angle and cylindrical hole fastening ensure secure mounting and repeatable positioning in compatible holders. Such geometry supports controlled cutting forces, leading to improved dimensional accuracy and surface finish in both external and internal turning tasks.

Compatibility and process guidance

Compatibility with a lathe holder depends on insert form, relief angle, tolerance class, fastening method, size and thickness. The TNMM designation and ISO code 160404 indicate the form and size, while the substrate material (carbide) and PCD top layer define the cutting behaviour. Select an appropriate chipbreaker and grade according to workpiece material and machine stability to exploit the DX120 advantages fully. For special applications or uncertain holder fits, a brief compatibility check with tooling data sheets is recommended.

Practical benefits in production

Using a PCD‑tipped indexable plate for aluminium and other non‑ferrous alloys increases process reliability and reduces overall tooling costs by extending tool life and lowering scrap rates. The DIA chipbreaker is tailored for non‑ferrous machining to improve chip control and reduce built‑up edge. These attributes make the insert particularly effective in high‑volume turning where repeatability and minimal intervention are priorities.

FAQ

What materials is this insert intended for? The TNMM 160404‑DIA DX120 Tungaloy indexable insert is intended primarily for aluminium, other non‑ferrous metals and abrasive non‑metallic materials, where PCD cutting edges give long tool life.

Can this insert be used for steel machining? No, PCD grades such as DX120 are not suitable for steel; the TNMM insert is optimised for non‑ferrous materials and abrasive non‑metals and may wear rapidly on ferrous alloys.

How is the insert secured in the holder? The insert features a cylindrical hole for fastening; correct holder selection must match the TNMM form, 0° relief, size and thickness for secure and repeatable mounting.

What benefit does the 0.4 mm corner radius provide? A 0.4 mm corner radius balances profile definition and edge strength, improving finish quality while maintaining resistance to chipping in finishing operations.

Is the DX120 grade better than carbide for aluminium? For many aluminium applications, DX120 PCD offers superior wear resistance and higher cutting speeds compared with carbide, resulting in longer tool life and improved surface consistency.
