CCGT09T302 J740 — CCGT ISO turning insert for turning by Tungaloy

CCGT09T302 J740 is an ISO‑standard rhombic indexable insert engineered for turning operations, supplying a balance of wear resistance and edge stability for both light finishing and stable production cuts.

• ISO-standard rhombic insert, size 09
• J740 grade for wear resistance and toughness
• 0.2 mm nose radius for fine finishing
• 7° relief angle, compatible with ISO holders

Durable grade and substrate for consistent cutting performance

The insert uses a Tungaloy J740 grade on a solid carbide substrate, selected to combine wear resistance with sufficient toughness for repeatable edge life under varied turning conditions. The J740 designation denotes a cutting material engineered to support stable chip formation and extended tool life where edge retention matters; this leads to fewer interruptions for insert changes and a more predictable machining process. As an ISO‑specified plate, the component integrates into established toolholders and clamping systems when the holder's form, relief angle and tolerance match the insert geometry.

Geometry and mounting designed for secure clamping and fine surface finish

A rhombic geometry with an effective cutting angle of 80°, a 0.2 mm nose radius and 3.97 mm thickness delivers both rigidity and the option for close finishing passes. The insert is supplied with a cylindrical hole and a single‑sided countersink (40°–60°), allowing stable fixation with common clamping screws and locating elements. These mechanical details reduce micro‑movement at the cutting edge, improving surface quality and repeatability. Compatibility with a holder is determined by the insert’s form, relief angle, tolerance class, fastening method, size and thickness — check these parameters when selecting the mating toolbody.

Practical benefits in production: chip control and easier process planning

The one‑sided chipbreaker design helps to direct swarf and manage cutting forces for predictable chip flow in turning tasks. The combination of the J740 grade and the chipbreaker supports steady metal removal rates and helps maintain edge stability over longer cycles, which in turn reduces downtime and scrap. For process planning, the insert’s ISO conformity and clearly defined geometrical data simplify inventory management and reordering. When selecting an insert for a particular job, choose the chipbreaker and grade to suit the workpiece material, type of cut and machine stability to obtain the best compromise between material removal rate and surface finish.

FAQ

What materials is the insert suitable for?
The CCGT09T302 J740 insert is a carbide indexable insert in the J740 grade; select the chipbreaker and cutting parameters to suit the specific workpiece material and machining conditions.

How is the insert fixed in the holder?
The insert uses a cylindrical hole with a single‑sided countersink (40°–60°) for screw clamping; ensure the holder matches the insert form, size and tolerance class for secure fixation.

What surface finish can be expected with the 0.2 mm radius?
A 0.2 mm nose radius on the CCGT09T302 supports fine finishing passes and improved surface quality when combined with appropriate feeds and speeds.

Is this insert compliant with ISO standards?
Yes, the plate follows ISO specifications for turning inserts; compatibility depends on matching the holder’s geometry and tolerance class.

Which chipbreaker does the plate use and what is its benefit?
The insert features a one‑sided chipbreaker designed to control swarf and stabilise cutting forces during turning operations.
