TCGT 080201 J740 triangular indexable turning insert, 7° relief by Tungaloy

The TCGT080201 J740 is an ISO‑standard triangular indexable insert designed for external and internal turning operations, offering a balance of wear resistance and edge stability for a wide range of turning tasks.

• ISO‑standard triangular insert
• J740 carbide grade, wear‑resistant
• 0.1 mm corner radius for fine finishing
• 7° relief angle, cylindrical hole with countersink

Consistent turning quality through defined geometry and grade

The triangular indexable insert features an ISO designation that ensures repeatable seating and secure clamping in compatible holders, reducing setup variation and downtime. Combined with the J740 carbide grade, the geometry provides a controlled balance of wear resistance and toughness, which helps maintain a stable cutting edge over longer tool life. This results in predictable component tolerances and fewer interruptions for insert changes.

Secure mounting and dimensional clarity for reliable clamping

Designed with a cylindrical hole and one‑sided countersink (40°–60°) and a 2.38 mm plate thickness, the insert offers clear mechanical engagement with standard ISO holders and clamping sets. The defined 7° relief angle reduces rubbing at the flank while the precise dimensions of the ISO form support consistent seating; both factors improve vibration resistance and toolholder security during medium‑ to high‑stability turning operations.

Application advantages from chip control and corner radius

Equipped with a one‑sided chipbreaker and a 0.1 mm corner radius, this insert supports fine finishing passes and controlled chip formation during finishing and light semi‑finishing cuts. The single‑side chipbreaker directs swarf away from the workpiece, aiding process stability and surface quality. The modest corner radius minimises edge strength compromise while enabling tight radii on workpiece features where required.

Material compatibility and selection guidance for productive turning

Intended for general turning tasks, the insert’s carbide composition and the J740 performance characteristics make it suitable for a broad range of materials when matched with the correct chipbreaker and machining parameters. Select feed rates and cutting speeds appropriate to the workpiece material and toolholder rigidity; the insert’s balanced properties favour applications where consistent cutting edge behaviour and predictable tool life are priorities.

FAQ

What operations is this insert suitable for? The TCGT080201 J740 insert is suitable for external and internal turning operations, offering good edge stability for finishing and light semi‑finishing passes.

How does the J740 grade affect tool life? The J740 carbide grade used in this insert balances wear resistance and toughness, which helps maintain a consistent cutting edge and can extend operational life under appropriate cutting conditions.

Can this insert be used in standard ISO holders? Yes, the ISO designation and defined thickness ensure compatibility with ISO‑standard turning holders and clamping systems when matched for form, size and tolerance.

What does the 0.1 mm corner radius mean for surface finish? A 0.1 mm corner radius provides a finer cutting edge profile, supporting improved surface finish on finishing passes while maintaining sufficient edge strength for general turning.

Is the insert suitable for heavy roughing cuts? The design and modest corner radius of this insert are optimised for finishing and light semi‑finishing; for heavy roughing, a different geometry or a grade designed for high toughness is recommended.
