CCGT09T304 GH330 CCGT — Turning Insert (Tungaloy) Rhombic ISO plate, 0.4 mm corner radius

The CCGT09T304 GH330 is an ISO rhombic indexable insert intended for turning applications, offering a single-sided chipbreaker and a cylindrical hole with a one-sided countersink for secure clamping.

• ISO rhombic insert, size 09
• GH330 grade for wear resistance
• 0.4 mm corner radius
• 7° clearance angle
• Cylindrical hole with countersink

High wear resistance and predictable tool life for turning

Manufactured from cemented carbide and specified in the GH330 Tungaloy grade, this insert is engineered to balance hardness and toughness for repeated turning cycles. The substrate and grade selection improve resistance to flank and crater wear, helping to maintain cutting-edge geometry over longer runs. This results in fewer insert changes and a more predictable production rhythm, supporting continuous machining and reduced downtime.

Secure mounting and ISO compatibility reduce setup risk

The insert conforms to ISO plate geometry and uses a cylindrical hole with countersink (40°–60°) to ensure consistent seating in compatible holders. The rhombic shape and defined 7° clearance angle reduce interference with the workpiece during entry and exit, while the plate thickness of 3.97 mm and standard tolerances simplify the selection of mating external holders or boring bars. The result is reliable clamping, repeatable location and reduced rework due to mounting errors.

Chip control and edge stability for efficient material removal

Equipped with a single-sided chipbreaker, the geometry promotes controlled chip formation in common turning tasks; this supports uninterrupted swarf evacuation and reduces the risk of entanglement on the tool or workpiece. The 0.4 mm corner radius provides a reinforced cutting edge that tolerates moderate interrupted cuts and contributes to surface finish quality during external and internal turning. For different workpiece materials and process stabilities, selecting the appropriate chipbreaker and grade variant is recommended to match feed and depth of cut.

Practical advantages that support productive machining

As a member of the ISO turning insert family, the plate simplifies inventory management: standard form factors and sizes facilitate replacement across machines. Consistent edge condition from the GH330 grade promotes steady component quality, while the combination of geometry and material supports higher material removal rates where process stability allows. Using standardised inserts also streamlines operator training and inspection routines, contributing to overall shop-floor efficiency.

FAQ

What turning tasks is this insert best suited for?
The CCGT09T304 GH330 insert is designed for external and internal turning; its geometry and chipbreaker make it suitable for general-purpose turning where a balance of wear resistance and edge stability is required.

Which holders accept this insert?
Holders and boring bars that match ISO rhombic plate form and accept size 09 plates with a cylindrical hole and countersink will be compatible; ensure the holder’s form, clearance angle and tolerance class match the insert.

How does the GH330 grade affect performance?
GH330 provides a balance of wear resistance and toughness, which helps the insert maintain cutting-edge stability over longer runs and supports reproducible component quality.

Can the insert handle interrupted cuts?
The 0.4 mm corner radius increases edge robustness and offers improved tolerance to moderate interruptions; however, process parameters should be adapted to the workpiece and stability conditions.

Is there guidance for choosing the chipbreaker?
Select the chipbreaker type according to material, feed and depth of cut; the single-sided chipbreaker on this insert supports controlled chip formation in many turning operations, but optimising the breaker to the specific workpiece enhances productivity.
