TCGT080202 J740 triangular turning insert for ISO turning applications — Tungaloy

A robust, ISO-standard triangular indexable insert (TCGT080202 J740) engineered for external and internal turning with optimised wear resistance and stable cutting-edge performance.

• TCGT080202 J740 ISO triangular insert
• Tungaloy carbide grade J740 for wear resistance
• 7° clearance angle and 60° cutting geometry
• Cylindrical hole with 40°–60° countersink

Consistent productivity through optimised grade and geometry

The combination of an ISO-standard geometry and the Tungaloy J740 carbide composition provides a clear production advantage: enhanced wear resistance with retained edge toughness. This insert is designed to sustain cutting forces during both roughing and finishing passes, which supports stable cycle times and reduces unplanned tool changes. For workshops seeking predictable performance, the hardened substrate and coating strategy of this grade translate into measurable increases in component throughput and reduced scrap rates.

Secure clamping and repeatable precision for every toolholder

Compatibility is determined by form, clearance angle, tolerance class, attachment method, size and thickness; with a 7° clearance and a 60° cutting geometry, the insert seats securely in standard holders. The cylindrical hole with a one-sided countersink (40°–60°) allows precise screw clamping and consistent axial location, while the triangle shape affords up to three renewed cutting edges per index. The 0.2 mm corner radius improves surface finish on contours and aids in chip formation control at moderate feeds, helping to achieve repeatable part tolerances.

Better chip control and broader application flexibility

A single-sided chipbreaker combined with the J740 grade provides controlled chip evacuation for a wide range of turning tasks. This geometry is suitable for external and internal turning of diverse materials when the correct chipbreaker and grade are selected according to workpiece stability and cutting conditions. Integrating the insert into a standard system—indexable insert, suitable holder or boring bar, shim/clamping set and replacement screws—enables quick setup changes and shorter downtime. The result is consistent surface finish and longer tool life, which supports operational efficiency in production shops and jobbing environments alike.

FAQ

What holders are compatible with this insert? The TCGT080202 J740 insert fits ISO-compatible triangular pockets; compatibility depends on form, clearance angle, tolerance class and attachment method—verify the holder accepts a triangle 08 insert with 2.38 mm thickness.

Which materials is the grade J740 suited for? Tungaloy’s J740 grade is formulated for general turning applications where wear resistance and edge stability are required; it performs well across a broad material range when paired with the appropriate chipbreaker and cutting data.

How many cutting edges are available per insert? The triangular geometry provides three usable cutting edges per indexable insert; rotating to a fresh edge restores original geometry and cutting performance.

What benefits does the 0.2 mm corner radius provide? A 0.2 mm corner radius smooths contact with the workpiece, improving surface finish and reducing stress concentrations at the cutting edge during finishing passes.

Is the insert supplied with clamping hardware? The insert is an ISO-standard indexable cutting insert; the typical system includes the insert itself plus compatible holder, shim/clamping set and replacement screws, which should be sourced to match the holder specification.
