VCMT160404-DIA DX120 — VCMT 160404 DX120 turning insert (PCD) by Tungaloy

The VCMT160404-DIA DX120 is an ISO-standard turning insert designed for high-speed aluminium and non-ferrous machining, combining polychrystalline diamond cutting edges with a carbide backing for long, consistent tool life.

• PCD grade DX120 for high cutting speeds
• ISO rhombic VCMT 160404 form
• 0.4 mm corner radius for fine finish
• Cylindrical hole with 40°–60° countersink

High-speed performance for aluminium and non-ferrous alloys

The insert’s polykristalliner Diamant (PCD) cutting layer, supplied as DX120, enables significantly higher cutting speeds and exceptional wear resistance when machining aluminium and other non-ferrous materials. The PCD microstructure resists abrasive wear from silicon-rich aluminium alloys and non-metallic abrasives, which translates into fewer tool changes and more stable cycle times in production. For machining operations that prioritise surface quality and repeatability, the hardened diamond cutting edge maintains geometry over long runtimes, reducing the need for frequent regrinding or replacement.

Precision geometry and secure clamping for consistent results

Designed to the ISO rhombic form, the insert fits common external holders and boring bars when the holder’s form, clearance angle, tolerance class, fastening method, size and thickness are matched. The 0.4 mm corner radius produces a fine finished edge without excessive cutting force, while the cylindrical hole with a single-sided countersink (40°–60°) ensures positive location and reliable clamping in indexable systems. The carbide substrate supports the diamond layer, providing mechanical stability during interrupted cuts and helping to maintain repeatable dimensional accuracy across batches.

Productivity gains and economical machining strategy

Using a PCD insert such as this grade DX120 often reduces overall machining cost per part through longer tool life and higher feeds and speeds compared with conventional carbide inserts when cutting suitable materials. The combination of diamond wear resistance and a robust backing minimises unplanned downtime and tool-change frequency, which benefits batch production and lights-out machining. Where abrasive, non-metallic inclusions are present, the DX120 grade offers a balance of durability and edge integrity, helping to keep process windows predictable and production throughput high.

FAQ

What materials is the insert intended for?
The DX120 PCD grade is designed primarily for aluminium and other non-ferrous metals, as well as abrasive non-metallic materials where diamond tooling provides superior wear resistance.

Which holders are compatible with this insert?
Compatibility requires a matching ISO rhombic form, correct clearance angle and tolerance class; the insert is intended for standard VCMT external holders and appropriate boring bars when those parameters are met.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm corner radius provides a balance between a fine surface finish and edge strength, suitable for finishing cuts on non-ferrous components without excessively increasing cutting forces.

Is the insert suitable for interrupted cuts?
Yes, the carbide backing under the PCD layer offers mechanical stability that helps withstand moderate interruptions; suitability depends on the specific application and cutting parameters.

What are the benefits of the DX120 grade compared with carbide inserts?
DX120 PCD delivers significantly longer tool life and higher achievable cutting speeds on suitable materials, reducing tool-change frequency and improving production consistency.
