TCGT110300 J740 Tungaloy – ISO triangle turning insert, 60° geometry, 7° clearance (Tungaloy)

A TCGT110300 J740 Tungaloy ISO turning insert designed for external and internal turning with a single‑sided chipbreaker and cylindrical hole with one‑side countersink

• ISO‑standard triangle insert
• J740 grade for wear resistance
• 7° clearance angle for secure cutting
• Cylindrical hole with 40°–60° countersink

Predictable fit and faster set‑up for ISO tooling systems

The ISO‑standard form of this triangle insert ensures immediate compatibility with matching holders when the correct form, clearance, tolerance class, fixing method, size and thickness are observed. The defined 7° clearance minimises flank contact and reduces thermal load on the tool, which leads to a more stable cutting process and fewer unexpected interruptions. For production environments that demand repeatable changeovers, the standardised geometry shortens set‑up time and supports sustained cycle rates.

Material behaviour and why J740 is a practical choice

The Tungaloy grade J740 brings a balanced combination of wear resistance and toughness tailored for turning operations. Manufactured from carbide, the grade is selected to maintain edge integrity under intermittent and continuous cuts, supporting component quality and tool life. This balance reduces the frequency of index changes and contributes to consistent surface finish, making the insert suitable where dependable machining performance and process stability are priorities.

Geometry and chip control for cleaner, safer cuts

The triangle shape with a 60° included angle offers rigidity and multiple indexable edges, while the single‑sided chipbreaker promotes efficient chip formation and evacuation in a range of turning tasks. The insert’s 3.18 mm thickness and size 11 profile provide mechanical stability during heavier cuts, and the cylindrical hole with a 40°–60° countersink secures reliable clamping. Together these features translate into improved process efficiency and lower risk of built‑up edge or unstable chips.

System integration and application notes for consistent results

When integrating this insert into a tooling set, select holders and clamping components that match the ISO designation and the insert’s dimensions to preserve cutting geometry and repeatability. The insert functions for both external and internal turning when mounted in the appropriate holder; choosing the correct chipbreaker and adapting feed/speed to the workpiece material will unlock the full potential of the grade. For complex setups or material‑specific guidance, technical consultation is recommended to optimise cycle times and surface quality.
