DCMT11T302 DX120 — ISO rhombic PCD turning insert by Tungaloy, 55° main angle

A DCMT11T302 DX120 ISO turning insert engineered for high-speed external and internal turning of aluminium, non-ferrous metals and abrasive non-metals.

• PCD grade DX120 for extended tool life
• Rhombic 55° geometry for diverse turning tasks
• 7° relief angle for stable chip formation
• Cylindrical hole with 40°–60° countersink

High-speed performance for non-ferrous machining

The insert uses polycrystalline diamond (PCD) in grade DX120, specifically developed for aluminium and other non-ferrous materials to deliver superior wear resistance and sustained cutting-edge integrity at elevated cutting speeds. The diamond cutting layer atop a carbide substrate enables very long tool life and consistent surface finishes where abrasive inclusions or fibrous materials would otherwise accelerate wear. By converting the technical properties of PCD into practical advantages, the tool reduces downtime caused by frequent tool changes and contributes to a smoother production flow.

Reliable geometry and secure clamping for predictable results

Designed as an ISO rhombic plate with a nominal 55° main angle and a 0.2 mm nose radius, the insert offers a balance between strength and profile accuracy for fine and semi-finish turning operations. The 7° relief angle supports positive cutting engagement and helps control chip evacuation, while the cylindrical hole with one-sided countersink (40°–60°) ensures repeatable seating and secure fastening in standard ISO-compatible holders. These mechanical details translate into consistent part tolerances and reduced variability across batches when the correct holder, size and tolerance class are matched.

Efficiency, economy and material versatility

Using the DX120 grade allows for aggressive feeds and speeds in the right workpiece classes, shortening cycle times and improving throughput. The PCD cutting layer resists built-up edge and maintains a sharp cutting face far longer than conventional carbide grades when machining aluminium and abrasive non-metals. In practice, this can lower tooling cost per component and raise overall process reliability — a clear economic argument for shops aiming to increase productivity without compromising surface quality.

Practical considerations for integration

The ISO-series design simplifies tool inventory: the plate fits holders determined by plate shape, thickness and hole style. With a plate thickness of 3.97 mm and a plate size of 11 mm, the insert suits compact setups and allows selection of matching toolholders or boring bars for internal work. When selecting a chipbreaker and specific grade, align the cutter geometry with the workpiece alloy, machining operation and system rigidity to exploit the full potential of the DX120 cutting material.

FAQ

What materials is this insert suited for?
The DCMT11T302 DX120 insert is intended for aluminium, non-ferrous metals and abrasive non-metals; the DX120 PCD grade provides excellent wear resistance for these materials.

Can the insert be used for both external and internal turning?
Yes, the ISO rhombic geometry and the available sizes make the insert suitable for both external and internal turning when paired with a compatible holder.

How does the PCD DX120 grade affect cutting parameters?
The polycrystalline diamond cutting layer of DX120 allows higher cutting speeds and longer tool life compared with conventional grades, enabling more productive machining for suitable workpieces.

What is the significance of the 7° relief angle and 0.2 mm nose radius?
The 7° relief angle reduces rubbing and supports stable cutting action, while the 0.2 mm nose radius offers a compromise between surface finish capability and edge strength for finishing operations.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the ISO designation facilitates selection of matching external holders or boring bars.
