CNMM 120404 DX120 — Turning indexable insert for turning, Tungaloy

The CNMM120404 DX120 is an ISO‑standard rhombic indexable insert with a polycrystalline diamond grade for high‑speed external and internal turning of aluminium and other non‑ferrous materials.

• Polycrystalline diamond DX120 grade
• ISO rhombic CNMM120404 geometry
• Optimised for aluminium machining
• Single‑sided chipbreaker for stable chips

High‑speed machining with durable PCD performance

The DX120 grade uses polycrystalline diamond (PCD) as the cutting material, offering high cutting speeds and long tool life when machining aluminium and other non‑ferrous alloys. PCD delivers a very hard, wear‑resistant cutting edge that reduces flank and crater wear compared with conventional carbide in these materials, so machining quality is maintained over extended production runs. This leads to measurable savings in tool consumption and fewer interruptions for tool changes, supporting higher overall throughput.

ISO compatibility and secure clamping reduce setup time

Manufactured to the ISO designation CNMM120404, the insert features a rhombic form with an 80° included angle, a 0° clearance angle and a plate thickness of 4.76 mm, ensuring predictable engagement with compatible holders. The insert is supplied with a cylindrical hole, allowing positive location and reliable clamping in standard indexable‑insert holders. Because compatibility is governed by form, clearance angle, tolerance class, fastening and thickness, the standardised geometry simplifies holder selection and minimises setup iterations on the machine.

Productivity benefits and process reliability in turning operations

The single‑sided chipbreaker provides consistent chip control for typical turning operations, reducing the risk of built‑up edge and enabling smoother evacuation of swarf in aluminium machining. This yields productivity gains through fewer stoppages and better surface finish per pass. For mixed batch production or long runs where tool life and repeatability matter, the insert helps lower the cost per part while maintaining consistent dimensional and surface quality. Metav Werkzeuge can advise on the most suitable holder and clamping set for a given machine and application to ensure optimal results.

FAQ

Which materials is this insert designed for?
The CNMM120404 DX120 insert is designed primarily for aluminium, other non‑ferrous metals and abrasive non‑metals, using the DX120 PCD grade to maintain wear resistance and cutting performance.

Is the insert compatible with standard CNMM holders?
Yes. The CNMM120404 geometry follows ISO standards so it fits holders designed for CNMM inserts, provided the holder matches the form, thickness and clamping style.

What advantage does the DX120 PCD grade offer over carbide?
The DX120 PCD grade offers substantially higher wear resistance and longer tool life when machining non‑ferrous materials, resulting in fewer tool changes and more consistent surface finish over long production runs.

Does the chipbreaker support stable chip control for finishing passes?
The single‑sided chipbreaker on this insert promotes predictable chip formation and evacuation, helping to achieve consistent finishes during both roughing and finishing passes with stable cutting conditions.
