DCMT 11T304 DX120 Tungaloy indexable insert for turning, PCD

The DCMT 11T304 DX120 is an ISO‑form indexable insert designed for external and internal turning of aluminium, non‑ferrous and abrasive non‑metallic materials, offering a PCD cutting layer for extended tool life and consistent surface quality.

• ISO indexable geometry for reliable fit
• PCD DX120 for high cutting speeds
• Excellent tool life and wear resistance
• One-sided chipbreaker for aluminium turning

Faster, more productive aluminium machining with PCD technology

The PCD cutting material in the DX120 grade delivers high cutting speeds and long tool life when machining aluminium and abrasive non‑metallics. Polycrystalline diamond provides a hard, wear‑resistant cutting face that significantly reduces flank wear and maintains edge sharpness over extended cycles; this means fewer interruptions for tool changes and a more consistent surface finish. The insert’s built‑in one-sided chipbreaker improves chip control in light to medium depth cuts, reducing the risk of built‑up edge and helping to keep cycle times down while preserving dimensional accuracy.

ISO geometry and stable seating for predictable results

The rhombic insert conforms to the ISO designation and is specified as a 55° approach angle with a 0.4 mm nose radius, a 7° clearance angle and a thickness of 3.97 mm. These geometric parameters ensure secure clamping and repeatable positioning in standard external holders and boring bars. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and thickness; correct matching minimises vibration and supports consistent cutting conditions. The insert also features a cylindrical hole with a single‑side countersink (40°–60°), enabling secure fixation and straightforward replacement during scheduled maintenance.

Practical system advantages and handling for workshop use

As part of an ISO turning system, the insert works together with a suitable external holder or boring bar, plus the appropriate shim/clamping set and replacement screws, to form a reliable cutting solution. The combination of a carbide substrate and a PCD cutting layer balances toughness with edge hardness: the substrate absorbs impact and supports the cutting layer, while the diamond face resists abrasive wear. For everyday shop practice, this translates into fewer tool changes, stable chip formation and an improved finish on aluminium components. When specifying inserts, select the chipbreaker and grade according to workpiece material, machining method and machine stability to achieve the best cost‑to‑performance ratio.

FAQ

What materials is this insert best suited for? The Tungaloy DCMT 11T304 DX120 insert is optimised for aluminium, non‑ferrous metals and abrasive non‑metallic materials owing to its PCD cutting face and DX120 grade.

How does the DX120 grade affect productivity? The DX120 grade provides a wear‑resistant edge that enables longer continuous cutting runs and higher cutting speeds, so the DCMT 11T304 DX120 insert reduces tool change frequency and supports consistent part quality.

Is the insert compatible with standard ISO holders? Yes; the insert follows ISO geometry, but compatibility depends on matching form, clearance angle, tolerance class, fastening method, size (11 mm) and thickness (3.97 mm) to the chosen holder.

What chip control can be expected when turning aluminium? The single‑sided chipbreaker on this insert promotes controlled chip formation in aluminium turning, improving evacuation and reducing the risk of chip entanglement.

Which system components are required to assemble the cutting system? A suitable external holder or boring bar, the correct shim or clamping set and the relevant replacement screws are required to form a complete and secure cutting assembly with this insert.
