DCGT 11T301 J740 turning insert by Tungaloy — 55° rhombic, 0.1 mm radius

The DCGT11T301 J740 is an ISO rhombic turning insert designed for external and internal turning, combining a balanced grade for wear resistance and edge stability with an ISO-compatible form for standard holders.

• ISO rhombic insert DCGT 11T301
• J740 Tungaloy carbide grade for wear resistance
• 55° cutting angle for versatile turning
• Single-sided chipbreaker with centre hole

Reliable cutting performance for general turning operations

This indexable insert is engineered for consistent metal removal in both external and internal turning tasks. The J740 grade provides a balance of wear resistance and toughness, helping to maintain a stable cutting edge under varying cutting conditions. The rhombic geometry with a 55° included angle and a 0.1 mm radius helps produce good surface finishes while maintaining edge strength; the small corner radius reduces cutting forces for fine finishing passes without sacrificing repeatable performance. The ISO designation 11T301 ensures predictable positioning and compatibility across standard toolholder systems.

Practical compatibility and setup guidance for efficient machining

Compatibility with a holder depends on the insert’s form, 7° relief angle, tolerance class, clamping method, size and thickness. The insert’s 3.97 mm thickness and the central mounting feature — a cylindrical hole with a one-sided countersink (40°–60°) — enable secure clamping with conventional clamping kits and screws, simplifying changeovers. The single-sided chipbreaker is designed for effective chip control in a wide range of feeds; when machining different workpiece materials or switching from roughing to finishing, select the chipbreaker and grade to match the stability of the setup and the desired surface quality.

Operational benefits that support productivity and tool life

Using a carbide insert with the specified geometry reduces unplanned stoppages thanks to consistent wear behaviour and easier edge indexing. The combination of a controlled corner radius and the J740 substrate contributes to longer effective tool life and predictable tool-change intervals, which in turn supports stable cycle times and lower machining costs per component. The insert’s ISO form and central hole make inventory and replacement simple, aiding quick maintenance routines and steady production flow.

FAQ

What machining tasks is this insert suitable for? The DCGT11T301 J740 insert is intended for external and internal turning where a balanced combination of wear resistance and toughness is required; it is suitable for general turning operations with a focus on consistent surface quality.

How is holder compatibility determined for this insert? Compatibility depends on the insert’s form, relief angle, tolerance class, clamping method, size and thickness; the 3.97 mm thickness and central hole with countersink are designed for use with standard clamping assemblies.

What effect does the 0.1 mm corner radius have on results? A 0.1 mm radius offers finer surface finishes and lower cutting forces compared with larger radii, while still providing adequate edge strength for finishing and light to medium turning passes.

Can this insert be used with standard screws and seats? Yes — the cylindrical mounting hole with a one-sided countersink (40°–60°) enables secure clamping in common toolholders and facilitates straightforward indexable insert changes.

When should a different chipbreaker or grade be chosen? Select the chipbreaker and grade based on the workpiece material, the machining type (roughing versus finishing) and the stability of the setup; the single-sided chipbreaker on this insert is aimed at reliable chip control across varied cutting conditions.
