VNMM160408-DIA DX120 – Indexable turning insert for high‑speed aluminium machining (Tungaloy)

The VNMM160408-DIA DX120 is an ISO‑standard rhombic indexable insert for turning, designed to deliver extended tool life and high cutting speeds when machining aluminium, other non‑ferrous metals and abrasive non‑metals.

• VNMM‑form ISO insert, size 160408
• PCD grade DX120 for aluminium & non‑ferrous
• Rhombic shape, 35° lead angle
• 0.8 mm corner radius, cylindrical hole

Consistent productivity through PCD technology

The PCD‑tipped grade DX120 offers a decisive productivity advantage where high cutting speeds and surface quality are required. As a polykristalliner diamond solution, the grade combines hardness and thermal conductivity to resist abrasive wear, delivering a long tool life and stable machining cycles. For shops seeking repeatable throughput on non‑ferrous components, this insert reduces tool changes and downtime, supporting uninterrupted production.

Precision geometry that simplifies holder selection

With an ISO‑compliant VNMM form (size 160408) and defined geometry — rhombic shape, 35° lead angle, 0° clearance and 4.76 mm thickness — the insert ensures predictable performance when paired with matching external holders. Compatibility depends on insert form, clearance angle, tolerance class, fastening and thickness; selecting the correct holder and clamping set yields secure seating and consistent cutting forces, which in turn improves dimensional stability on turned parts.

Application benefits and material suitability

Specified for turning, the insert is especially suitable for aluminium and other non‑ferrous alloys as well as certain abrasive non‑metallic materials. The PCD cutting layer reduces built‑up edge and adhesion problems commonly encountered in soft, gummy alloys, enabling higher feeds and superior surface finish. Where abrasive inclusions or fillers are present, the wear resistance of the grade helps maintain component tolerances over longer tool life, lowering per‑part tooling cost.

Practical considerations for shop use

The VNMM‑type insert includes a cylindrical hole for secure fastening and a 0.8 mm corner radius to balance edge strength with finishing capability. Its ISO standardisation simplifies inventory management across multi‑machine environments. Given the tool’s focus on high‑speed machining, machining parameters should be adapted to the workpiece alloy and toolholder rigidity; appropriate chipbreaker selection and coolant strategy (if applicable) will further extend service intervals and preserve surface integrity.

FAQ

What materials is this insert best suited for? The VNMM160408‑DIA DX120 insert is optimised for aluminium and other non‑ferrous alloys; it also performs well on certain abrasive non‑metal materials due to the PCD cutting layer.

Can the insert be used for both external and internal turning? Yes, the ISO VNMM form and DX120 grade are suitable for both external and internal turning operations when the correct holder and clamping arrangement are used.

How does the DX120 PCD grade affect cutting speeds? The DX120 PCD grade enables significantly higher cutting speeds compared with conventional carbide, allowing faster cycle times and extended tool life on compatible materials.

What key holder characteristics must be matched to ensure compatibility? Compatibility depends on insert form, clearance angle, tolerance class, fastening method, size and thickness; ensure the external holder is specified for VNMM 160408 geometry.

Is the insert supplied with fastening hardware? The insert is supplied as the indexable cutting element; holders, clamping sets and replacement screws are part of the system and should be ordered separately according to machine and holder specifications.
