TCGT 110301 J740 triangular indexable turning insert – Tungaloy, 60° main cutting edge, with 7° clearance

TCGT110301 J740 is a triangular indexable insert designed for general turning applications and ISO-conforming tool holders

• Triangle ISO insert 60° geometry
• Tungaloy grade J740 for balanced wear resistance
• 0.1 mm corner radius and 7° clearance angle
• Cylindrical hole with 40°–60° countersink

Reliable fit with ISO-compatible holders for fast changeovers

The ISO-conforming design ensures that the insert sits correctly in standard external and internal turning holders; compatibility is defined by shape, clearance angle, tolerance class, clamping arrangement, size and thickness. For workshop planners this means predictable set-up behaviour and repeatable cutting positions, reducing downtime during tool changes. The presence of a cylindrical hole with one-sided countersink (40°–60°) helps to secure the insert reliably in the seat and contributes to stable clamping under varying cutting forces.

Balanced material grade for longer tool life and edge stability

The J740 grade from Tungaloy combines carbide substrate properties tuned for turning tasks with a formulation that balances wear resistance and toughness. This balance reduces flank wear while maintaining cutting-edge stability during intermittent cuts or when workpiece material varies. For production batches where consistent tool life is essential, the grade supports predictable replacement intervals and stable surface finish over extended runs.

Geometry and chip control that support process reliability

The triangular 60° cutting angle paired with a 0.1 mm corner radius delivers a compromise between strength of the cutting edge and the ability to achieve fine surface finishes. The single-sided chipbreaker assists in controlled chip formation for a range of turning operations, helping to avoid long, stringy chips and improving swarf evacuation. As a result, machining cycles run cleaner and machine tool downtime caused by chip entanglement is reduced.

Practical dimensions and handling for everyday workshop use

With a plate thickness of 3.18 mm and an inscribed size of 11, the insert offers robust seating and good edge support in standard clamping systems. The moderate clearance angle of 7° minimises risk of rubbing while preserving edge strength at engagement. For operations that require frequent indexing, the triangular form provides up to three indexable edges, making replacement cycles economical and reducing inventory variety in the holder stock.

FAQ

What is the primary application of this insert?
The TCGT110301 J740 insert is intended for turning operations and is suitable for a broad range of general turning tasks where balanced wear resistance and edge stability are required.

How is compatibility with tool holders ensured?
Compatibility is determined by shape, clearance angle, tolerance class, clamping method, size and thickness; the TCGT110301 follows ISO conventions so it matches standard ISO turning holders when those parameters align.

How many cutting edges are available per insert?
A triangular indexable insert normally provides up to three indexable cutting edges, allowing economical re‑indexing and extended use before replacement.

What benefits does the J740 grade provide?
The J740 grade offers a balance of wear resistance and toughness, promoting longer edge life in varied turning conditions while maintaining surface finish and edge stability.

Does the insert support secure clamping under heavy cuts?
The combination of 3.18 mm thickness, a cylindrical hole with countersink and ISO-compatible geometry ensures secure seating and stable clamping for reliable performance under typical turning forces.
