DCGT 11T302 J740 turning insert — rhombic ISO turning insert, 55° — Tungaloy

The DCGT11T302 J740 is a rhombic, ISO-standard turning insert for external and internal turning, offering a balanced combination of wear resistance and edge stability for production machining.

• ISO-standard rhombic insert for turning
• J740 Tungaloy carbide grade for durability
• One-sided chipbreaker for reliable chip control
• Cylindrical hole with single-side countersink (40°–60°)

Consistent cutting performance from material and geometry

The combination of the J740 carbide grade and the rhombic geometry delivers a stable cutting edge that supports longer tool life and predictable wear behaviour. The grade balances wear resistance and toughness to resist chipping under interrupted cuts while maintaining a sharp cutting edge for good surface finish. Specifying the correct insert geometry reduces machining variability and increases throughput in repetitive turning operations.

Secure seating and repeatability for workshop workflows

A cylindrical hole with a single-side countersink ensures correct seating and axial location in compatible holders, which translates into repeatable results across insert changes. The ISO interface and standardised form factor make the insert straightforward to integrate into existing tool systems: proper clamping minimises micro-movements and supports dimensional accuracy. Clear tolerance classes and mounting features aid quick tool exchanges and reduce setup time on production lines.

Application scope and chip control for efficient machining

Designed for a broad range of turning tasks, the insert suits both external and internal turning when matched with an appropriate holder and cutting parameters. The one-sided chipbreaker enhances chip formation for many turning operations, while the modest 0.2 mm corner radius and 7° relief angle offer a compromise between fine surface finish and edge strength. Select the chipbreaker and grade according to the workpiece material and machining stability to maximise productivity and part quality.

FAQ

What applications is this insert intended for?
The DCGT11T302 J740 Tungaloy insert is intended for external and internal turning operations and is optimised for stable, repeatable cutting in production environments.

How does the J740 grade affect machining performance?
The J740 grade provides a balance of wear resistance and toughness; in the DCGT11T302 J740 insert this supports longer tool life and edge stability under typical turning conditions.

Is the insert compatible with standard holders?
Compatibility depends on insert form, relief angle, tolerance class, fastening and thickness; the ISO designation and the cylindrical hole with countersink facilitate mounting in standard ISO-pattern holders.

Which chipbreaker should be selected for difficult materials?
For less stable setups or more difficult-to-cut materials, choose a chipbreaker and cutting parameters that emphasise controlled chip flow; the one-sided chipbreaker on this insert improves chip control in many turning tasks.

What are the key dimensional features to check when replacing an insert?
Verify insert form (rhombic), size (11 mm), thickness (3.97 mm), relief angle (7°), corner radius (0.2 mm) and the presence of the correct hole and countersink to ensure proper fit and repeatability.
