TCGT 080202 J740 indexable turning insert for turning – Tungaloy

A TCGT 080202 J740 indexable turning insert engineered for ISO-compliant external and internal turning applications with a triangular footprint and secure mounting

• ISO-compliant triangular insert size 08
• J740 grade for wear resistance
• 7° clearance angle for secure cutting
• Cylindrical hole with single-side countersink

Reliable cutting performance and extended tool life

The combination of a carbide substrate and the J740 grade delivers a stable balance of wear resistance and edge toughness. This results in consistent cutting performance across medium-duty turning tasks, reducing unexpected tool changes and supporting predictable cycle times. The material and grade selection is intended to withstand variable contact stresses while retaining edge geometry, which helps to maintain dimensional accuracy over repeated indexings.

Secure clamping and machine compatibility for predictable results

The insert follows ISO indexing conventions, so compatibility with holders is defined by form, clearance angle, tolerance class, fastening, size and thickness. The 7° clearance angle and the cylindrical hole with a single-sided countersink (40°–60°) allow secure fixation in a matched outer holder or boring bar. With a plate thickness of 2.38 mm and an ISO 08 size, the component integrates into common tool systems to provide repeatable seating and torque transmission during turning operations.

Controlled chip formation and surface quality

A dedicated one-sided chipbreaker supports efficient chip control and evacuation when paired with appropriate cutting parameters. The small corner radius of 0.2 mm enables fine radiused profiles and contributes to improved surface finish on turned parts. Choosing the matching chipbreaker geometry and the J740 grade helps to balance chip form, reduce built-up edge risk and deliver consistent part quality for both external and internal turning tasks.

Practical system setup and intended applications

This indexable triangle insert is intended for turning; typical system components include the ISO insert, a matched external holder or boring bar, a support/clamp set and replacement screws. Selection of the exact chipbreaker and grade should match the workpiece material, the intended machining method and the available process stability. The insert suits workshops and CNC departments seeking a robust, ISO-compliant cutting edge for a wide range of routine turning operations.

FAQ

What materials is this insert intended for? The Tungaloy TCGT 080202 J740 insert is designed for general turning applications; the correct chipbreaker and cutting data should be chosen to match the specific workpiece material and machining conditions.

How is the insert secured in the toolholder? The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping in compatible ISO holders or boring bars, combined with the 7° clearance for correct seating.

What surface finish can be expected with a 0.2 mm corner radius? A 0.2 mm corner radius supports fine profile radiusing and improved surface finish when combined with appropriate feeds and speeds and the matching J740 grade.

Can this insert be used for both external and internal turning? Yes, the triangular ISO form and the chipbreaker design make it suitable for both external and internal turning, provided the correct holder and process stability are in place.

Which system components are required for a full tooling setup? A complete tooling system typically comprises the indexable insert, a matching outer holder or boring bar, a clamp/support set and replacement screws to ensure repeatable assembly and reliable cutting forces.
