CCGT09T300 J740 ISO turning insert, rhombic 09, 80°, 7° — Tungaloy

A CCGT09T300 J740 ISO-standard turning insert intended for external and internal turning, combining a wear-resistant carbide grade with a single-sided chipbreaker for dependable, repeatable machining.

• ISO-standard rhombic insert, size 09
• J740 grade Tungaloy carbide for wear resistance
• 7° clearance angle for stable cutting action
• Cylindrical hole with 40°–60° countersink

Consistent fit and measurable process reliability

The ISO standardisation of the insert ensures compatibility with holders when matched by form, clearance angle, tolerance class, fastening type, size and thickness. A correct match reduces vibration and run-out, which leads to a stable cutting edge and reproducible results in production. The 7° clearance and the 80° cutting geometry produce a predictable cutting force vector that helps maintain dimensional accuracy, while the 3.97 mm plate thickness contributes to mechanical rigidity during interrupted or heavy cuts.

Durable cutting performance from a specialised grade

The J740 grade is a Tungaloy-developed carbide composition optimised for turning, balancing wear resistance and toughness to preserve the cutting edge under varied conditions. Combined with the insert's single-sided chipbreaker, the design promotes effective chip control in many turning scenarios and reduces rework. For those less familiar with cutting grades: the term denotes the engineered microstructure and coating approach that determine how the insert resists abrasion and mechanical shock, which directly affects tool life and machining economy.

Practical application and system considerations for shop-floor use

The rhombic profile and the cylindrical hole with a single-side countersink (40°–60°) facilitate secure clamping and straightforward indexing in compatible external holders or boring bars. Typical system components include the ISO insert itself, a matched external holder or bar, an underlay/clamping set and replacement screws. For external and internal turning operations, selecting the correct chipbreaker and the J740 grade according to workpiece stability and material type delivers improved surface finish and higher productivity. The insert's characteristics make it suitable where process reliability and repeatability are priorities.

FAQ

What types of turning is this insert suitable for?
The CCGT09T300 J740 insert is designed for both external and internal turning and performs well where stable chip control and edge integrity are required.

How does the J740 grade affect tool life?
The J740 Tungaloy grade balances wear resistance and toughness, which helps maintain the cutting edge for longer periods under normal turning conditions.

What does the single-sided chipbreaker mean in practical terms?
A single-sided chipbreaker provides predictable chip formation on the active cutting edge, aiding evacuation and reducing the risk of chip entanglement during turning operations.

How is the insert secured in the holder?
The insert features a cylindrical hole with a single-side countersink (40°–60°) that enables positive clamping in compatible ISO holders and boring bars.
