CCGT 09T301 J740 Tungaloy — Indexable turning insert for turning

CCGT09T301 J740 is an ISO-standard indexable turning insert designed for external and internal turning where edge stability and consistent wear resistance are required

• ISO-standard rhombic 80° geometry
• J740 Tungaloy grade for wear resistance
• Central hole with countersink 40°–60°
• Corner radius 0.1 mm for fine finishes

Reliable cutting performance that boosts productivity

The combination of the J740 grade and a carbide substrate delivers a balanced mix of wear resistance and toughness, which directly supports longer tool life and fewer insert changes during series production. The geometry is optimised for stable cutting forces, so the indexable insert achieves consistent material removal rates and reduces downtime. For process planners, this means improved machining economy and predictable cycle times when the correct chipbreaker and grade are matched to the workpiece material.

Simple compatibility with standard toolholders for fast set-up

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fixation, size and thickness; the rhombic 80° shape and cylindrical hole with one-sided countersink (40°–60°) ensure secure clamping and repeatable seating in many common holders. The corner radius 0.1 mm and plate thickness 3.97 mm are standard dimensions that facilitate quick integration into existing toolsets, reducing fixture adjustments and setup time on the shop floor.

Achieve fine surface finishes and dimensionally accurate turns

The small 0.1 mm corner radius is ideal for fine finishing passes and for maintaining tight tolerances on turned features. The single-sided chipbreaker directs chips away from the contact zone, improving surface integrity and reducing the risk of built-up edge. Where fine detail and repeatability matter, the insert’s geometry and grade combination supports stable cutting edges and a predictable finish with fewer corrective passes.

Practical selection advice for process reliability

Choose the chipbreaker style and the J740 grade to match workpiece material, machining type and part stability; a softer grade may be chosen for interrupted cuts, while the J740 composition favours productive, continuous cuts with enhanced edge life. If material-specific guidance is required, selection based on cutting data and holder compatibility will help to maximise both productivity and process security.

FAQ

What applications is this insert suited to?
The CCGT09T301 J740 insert is intended for external and internal turning operations and is well suited to fine finishing and general turning tasks when combined with the correct chipbreaker and holder.

How does the J740 grade affect tool life?
The J740 Tungaloy grade offers a balance of wear resistance and toughness that extends edge stability in continuous turning, helping to reduce the frequency of insert changes.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fixation, size and thickness; the rhombic 80° geometry and central hole with countersink are designed for common ISO-compatible turning holders.

What cutting behaviour can be expected from the 0.1 mm radius?
A 0.1 mm corner radius provides precise finishing capability and improved surface quality on turned parts, while maintaining good edge strength for light to moderate cutting conditions.

Is the insert indexable and reversible?
Yes, the insert is an ISO-standard indexable type; edges can be indexed to present fresh cutting geometry, which contributes to economical use of the insert.
