CCGT 09T302 J740 CCGT 80° rhombic ISO turning insert by Tungaloy

A CCGT09T302 J740 Tungaloy indexable insert intended for external and internal turning, offering a rhombic 80° geometry and a single-sided chipbreaker for controlled chip formation

• ISO rhombic insert, 80° cutting edge
• J740 Tungaloy carbide grade, high wear resistance
• Single-sided chipbreaker for stable cutting
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for general turning

The insert is engineered for stable machining cycles in a broad range of turning tasks. As an ISO-standard rhombic insert with an 80° cutting edge, it delivers a predictable approach angle that supports robust engagement during both external and internal turning. The J740 grade is a Tungaloy carbide formulation optimised for a balance of wear resistance and toughness, which translates into extended life under intermittent loading. The single-sided chipbreaker supports manageable chip flow, reducing downtime for manual chip clearing and helping to protect the toolholder and workpiece from erratic cutting forces.

Mounting, geometry and compatibility explained for correct assembly

Compatibility with the selected toolholder depends on several geometric parameters: insert form, 7° relief angle, tolerance class, attachment type, size and 3.97 mm thickness. The rhombic shape and the 0.2 mm corner radius favour fine finishing and close-tolerance turning where small radius details are required. The insert is supplied with a cylindrical hole with a single-sided countersink (40°–60°), enabling secure clamping in holders designed for ISO rhombic plates. When selecting an insert seat and clamp, ensure the holder matches the plate size 09 and thickness to maintain correct seat contact and repeatability.

Material grade and machining advantages for reliable productivity

The carbide base material combined with the Tungaloy J740 coating/grade provides improved resistance to flank and crater wear while maintaining edge stability under variable cutting conditions. For component production where repeatability and surface finish matter, this combination reduces the frequency of insert changes and supports longer uninterrupted cutting times. The single-sided chipbreaker design encourages a stable chip geometry suitable for a wide range of steels and alloyed materials, helping to maintain lower cutting forces and consistent surface quality; this simplifies process planning and supports higher overall productivity.

FAQ

What materials is this insert suitable for?
The CCGT09T302 J740 insert is designed for general turning and, with the Tungaloy J740 carbide grade, offers a balance of wear resistance and toughness suitable for a broad range of steels and alloyed materials.

How is the insert secured to the holder?
This indexable insert features a cylindrical hole with a single-sided countersink (40°–60°) and must be used with a compatible holder that matches the ISO rhombic seat, the plate size 09 and the 3.97 mm thickness to ensure correct clamping and repeatability.

What does the 0.2 mm corner radius mean for surface finish?
A 0.2 mm corner radius provides finer edge geometry for closer tolerances and improved surface finish on turned components; it is suitable where precise radii or reduced tool marks are required.

Can the insert be used for internal turning as well as external?
Yes, the rhombic geometry and the 80° cutting edge make the plate suitable for both external and internal turning applications when mounted in the appropriate holder.

How does the J740 grade affect tool life?
The J740 Tungaloy carbide grade combines wear resistance with sufficient toughness to maintain edge stability, which generally extends tool life and helps sustain consistent performance over longer production runs.
