CCGT09T304 AH725 – ISO turning insert CCGT for turning, PVD-coated carbide, 0.4 mm radius by Tungaloy

The CCGT09T304 AH725 is an ISO-standard rhombic turning insert designed for external and internal turning applications, offering universal, breakage-resistant performance for steel and stainless steels.

• ISO rhombic turning insert CCGT09T304
• PVD-coated AH725 carbide grade
• 0.4 mm corner radius for consistent profiles
• Cylindrical hole with one-sided countersink
• Designed for external and internal turning

Stable process security for mixed steel production

The combination of a PVD-coated surface and the AH725 grade provides a balance between toughness and wear resistance that supports stable machining across varying steels, including stainless variants. The coating reduces adhesive wear and supports higher cutting temperatures, which results in fewer unexpected tool changes and a more predictable production rhythm. As a consequence, cycle times become more reliable and scrap rates are decreased, particularly where batch materials vary or component geometries demand consistent tool life.

Geometry engineered for repeatable part quality

A 0.4 mm corner radius and an 80° lead angle on the rhombic profile maintain form accuracy and enable controlled chip formation at the cutting edge. The one-sided chipbreaker is matched to the grade to assist chip control during both external and internal turning, reducing the risk of built-up edge on stainless steels and tough alloys. The geometry supports a repeatable surface finish and dimensional stability, so finishing passes are minimised while tolerances remain tight.

Simple mechanical integration and robust clamping

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening, size and thickness; the insert’s with-hole design and the specified cylindrical hole with one-sided countersink (40°–60°) ensure secure seating and straightforward fixation in common ISO CCGT holders. The 3.97 mm plate thickness and size 09 fit many standard external holders and boring bars, facilitating fast changeover and reliable torque transfer. This predictable fit helps maintain consistent cutting conditions across shifts and operators.

Reduced process risk through material choice and coating

Manufactured from fine-grain carbide and finished with a PVD layer, the insert combines fracture resistance with edge stability, making it suitable for smaller tools and operations where process safety is critical. In short, the grade selection and coating strategy reduce the incidence of edge chipping and improve overall tool life when machining medium to high-strength steels and stainless steels, particularly under variable machining conditions.

Application-focused guidance for planners and operators

For external and internal turning tasks where material groups change or where high process reliability is required, this insert offers a pragmatic compromise between economy and performance. Selection of feed, depth of cut and holder rigidity should reflect the intended material and machining strategy; the insert’s universal character simplifies tooling inventories while preserving performance. Compatibility checks against holder geometry and clamping method are recommended prior to series use.

FAQ

What materials is the CCGT09T304 AH725 best suited for?
The CCGT09T304 AH725 insert is engineered for machining steel and stainless steels, offering a universal, breakage-resistant performance suited to mixed-material production.

How does the PVD coating affect tool life?
The PVD-coated AH725 grade boosts wear resistance and reduces adhesive wear at elevated temperatures, which extends tool life under standard turning conditions.

Which holders are compatible with this insert?
Compatibility is determined by the insert form, clearance angle, tolerance class, fastening, size and thickness; the CCGT09T304 is designed to seat in standard ISO CCGT holders with corresponding clamping systems.

What chip control can be expected with the one-sided chipbreaker?
The one-sided chipbreaker, matched to the AH725 grade, supports controlled chip formation for both external and internal turning, improving evacuation and reducing re-cutting.

Are there any special considerations for stainless steels?
When machining stainless steels, the PVD coating and robust carbide substrate of this insert help minimise built-up edge; however, cutting parameters should be adapted to material toughness and thermal conductivity.
