CCMT09T308 GH730 indexable insert for turning — Tungaloy

A CCMT09T308 GH730 indexable insert engineered for external and internal turning, featuring a single-sided chipbreaker and a cylindrical mounting hole with a 40°–60° countersink.

• ISO rhombic CCMT geometry for versatile turning
• GH730 grade: wear-resistant, balanced toughness
• 0.8 mm corner radius for precise edge definition
• Cylindrical hole with 40°–60° countersink

Stable cutting performance for productive turning

The GH730 carbide grade is formulated to balance wear resistance and toughness, delivering consistent cutting behaviour in demanding turning tasks. This combination reduces unexpected tool failure and supports predictable tool life, which improves process stability on production lines. The insert’s geometry and the single-sided chipbreaker are optimised for effective chip control during both external and internal turning, which helps maintain cycle times and contributes directly to manufacturing efficiency.

Reliable fit and secure clamping for repeatable accuracy

As an ISO-standard insert with a rhombic CCMT form, the component is designed to mate with compatible holders; fit depends on form, clearance, tolerance class, fastening method, size and thickness. The insert’s cylindrical hole with a 40°–60° countersink and the 7° clearance angle ensure secure seating and correct rake orientation when used with matched clamping systems. Proper clamping reduces vibration and runout, which in turn improves dimensional repeatability and surface integrity on turned parts.

Better surface finish and robust edge strength

The 0.8 mm corner radius provides a balance between strength and finishing capability: small enough to achieve fine surface quality yet large enough to add support to the cutting edge under moderate feeds. The 3.97 mm plate thickness contributes to edge stability during interrupted cuts or heavier engagement, lowering the risk of edge chipping. The single-sided chipbreaker is tailored to form short, controlled chips for typical turning operations, simplifying chip handling and reducing the likelihood of rework.

Practical advantages for shop-floor operations

Using a standardised ISO insert simplifies inventory and tooling logistics while enabling quick index changes to restore a sharp cutting edge. The combination of a dedicated Tungaloy grade and ISO compatibility supports consistent tool performance across batches, aiding process planning and reducing unplanned downtime. Where surface quality and tool life are priorities, selecting the correct chipbreaker and pairing the insert with a suitable holder will yield measurable improvements in throughput and repeatability.

FAQ

Is this insert suitable for both external and internal turning? Yes. The CCMT09T308 GH730 insert is intended for external and internal turning, with geometry and chip control features tailored to those operations.

What clamping provisions are required for safe use? The insert requires a matched ISO CCMT holder that accommodates the form, clearance, tolerance class, fastening method, size and thickness; the cylindrical hole plus countersink secures correct seating.

How does the GH730 grade influence tool life? GH730 is engineered to combine wear resistance and toughness; in the CCMT09T308 configuration this supports stable edge life and predictable wear, improving uptime and reducing insert changes.

What effect does the 0.8 mm corner radius have on surface finish? A 0.8 mm radius gives a compromise between edge strength and finishing capability, enabling finer finishes at moderate feeds while maintaining resistance to edge chipping.

Can the chipbreaker be used for different materials and feeds? The single-sided chipbreaker is optimised for common turning conditions; performance depends on workpiece material and cutting parameters, so selecting the suitable chipbreaker and grade for the material is recommended.
