TCGT 110300 J740 Tungaloy — ISO turning indexable insert, triangular 11 mm, 7° relief

A TCGT 110300 J740 Tungaloy ISO-format indexable insert for external and internal turning, engineered to provide stable chip control and robust edge stability in demanding machining tasks.

• ISO‑format triangular insert 11 mm
• J740 Tungaloy carbide grade
• 7° relief for reliable clearance
• Cylindrical hole with 40°–60° countersink

Precision and predictable performance for turning operations

The triangular indexable insert is manufactured to ISO dimensions, ensuring repeatable positioning and compatibility with standard holders. The 11 mm inscribed circle and 3.18 mm thickness give a stable seating in the pocket, reducing chatter and improving surface finish. ISO conformity simplifies tool inventory and shortens setup time in production environments where predictable outcomes are crucial, enabling higher process reliability and lower scrap rates.

Balanced J740 grade for wear resistance and edge stability

The J740 cutting grade from Tungaloy combines wear resistance with sufficient toughness to withstand interrupted cuts and variable feeds. This balance extends effective tool life and reduces frequency of insert changes, which in turn lowers downtime and tooling costs. For users less familiar with grades: J740 is optimised to maintain a robust cutting edge across a wide material range typically encountered in general turning.

Mounting, geometry and practical compatibility guidance

The insert features a cylindrical hole with a single‑sided countersink (40°–60°), which secures consistent clamping force and correct axial positioning when used with compatible clamping screws and seats. The 7° clearance angle prevents rubbing while maintaining sufficient support behind the cutting edge. Compatibility with a specific holder depends on form, relief, tolerance class, clamping method and insert thickness; selecting the correct combination ensures repeatable clamping and predictable cutting behaviour.

Chip control and application considerations

A one‑sided chipbreaker geometry offers controlled chip formation for many turning tasks, aiding evacuation and reducing heat build‑up at the cutting zone. When paired with appropriate cutting data and coolant strategy, the insert helps to maintain surface integrity and tool life. For efficient machining, choose feeds and speeds that match workpiece material and machine rigidity; the insert is suitable for both external and internal turning where ISO triangular inserts are recommended.

FAQ

What materials is this insert suitable for?
The J740 grade is a versatile Tungaloy carbide designed for general turning applications; the insert suits a broad range of materials where a balanced wear resistance and toughness are required.

How is the insert secured in the holder?
The insert uses a cylindrical hole with a single‑sided countersink (40°–60°); correct clamping hardware and seat geometry ensure stable fixation for repeatable cutting.

Can this insert be used for internal boring as well as external turning?
Yes, the ISO triangular format and chipbreaker design make the insert appropriate for both external and internal turning tasks when matched with a compatible holder.

What advantage does the 7° relief provide?
The 7° relief angle prevents flank rubbing while maintaining solid edge support, improving surface finish and reducing undesirable heat generation at the cutting zone.
