CCMT 09T304 GH730 Tungaloy ISO turning insert — rhombic, 80° included angle, 0.4 mm radius

The CCMT09T304 GH730 Tungaloy ISO turning insert is designed for external and internal turning, combining a robust carbide grade with a controlled chipforming geometry for stable, high-productivity machining.

• ISO rhombic insert CCMT 09T304
• GH730 grade for wear resistance
• 80° cutting geometry for stable engagement
• 0.4 mm nose radius for fine finishing

High-performance grade for longer tool life and stable cutting

The combination of the GH730 cutting grade and a solid carbide substrate delivers a good balance of wear resistance and edge toughness, which supports longer tool life in demanding turning operations. The single-sided chip control geometry complements the grade by directing chips reliably away from the cutting zone, reducing interruptions and minimising tool-change frequency. This results in a measurable improvement in process uptime and consistent part quality when compared with less optimised insert grades.

Geometry and clamping designed for repeatability and rigidity

The rhombic ISO plate with an 80° included angle and a 7° clearance ensures secure seating in matched holders and predictable engagement during both external and internal turning. The insert includes a cylindrical centre hole with a one-sided countersink (40°–60°), and a plate thickness of 3.97 mm that supports stable clamping under moderate cutting forces. These dimensions contribute to repeatable positioning and reduced vibration, which together improve surface finish and dimensional stability across production runs.

Process guidance: application scope and finishing capability

Intended primarily for turning operations, the insert is suited to a wide range of machining tasks where the balance between wear resistance and edge stability is essential. The 0.4 mm nose radius helps achieve superior surface quality on fine finishing passes, while the single-sided chipbreaker should be chosen to match the workpiece material, cutting parameters and machine rigidity. For different batch sizes or materials, selecting the appropriate chipbreaker and cutting data will directly affect cycle times and overall machining economy; technical advice is available for process optimisation.

FAQ

What work is this insert intended for? The CCMT09T304 GH730 insert is intended for external and internal turning and is optimised for stable chip control and wear resistance in general turning operations.

How does the GH730 grade affect performance? The GH730 grade provides an improved balance between wear resistance and edge stability, which helps maintain tool life and consistent cutting performance under normal turning conditions.

Which holders are compatible with this ISO insert? Compatibility depends on the holder's form, clearance, tolerance class, fastening method, size and plate thickness; matching those parameters ensures proper seating of the CCMT09T304 insert.

What finishing quality can be expected with a 0.4 mm nose radius? A 0.4 mm nose radius supports fine finishing passes and can deliver improved surface finish when combined with appropriate feeds and speeds and a stable clamping setup.
