CCMT09T304 AH725 ISO turning insert — rhombic 80° cutting geometry by Tungaloy

A CCMT09T304 AH725 indexable turning insert for external and internal turning, designed as an ISO‑standard rhombic insert with a 7° clearance angle and one-sided chipbreaker.

• ISO rhombic insert, 80° cutting geometry
• PVD-coated carbide, universal AH725 grade
• 0.4 mm nose radius for medium finishing
• Suitable for external and internal turning

High process reliability with a universal PVD grade

The PVD-coated carbide substrate with the AH725 grade delivers consistent performance across a range of steels and stainless steels, providing stable chip formation and extended edge life. This universal, fracture-resistant grade is particularly suitable where workpiece materials vary or where smaller toolholders are used; the result is fewer interruptions and more predictable tool‑change intervals. The ISO designation and standardised form ensure the cutting edge geometry is repeatable, which supports reproducible component quality and reduces setup time on the shop floor.

Compatibility and secure clamping for trouble‑free operation

Compatibility with the toolholder is determined by the insert form, 7° clearance angle, tolerance class, fastening method, size and thickness. The rhombic form and the cylindrical hole with a single‑side countersink (40°–60°) permit dependable clamping in compatible holders and allow the insert to be used in both external and internal turning operations. Specifying the correct holder and clamping kit avoids misalignment and ensures the insert sits at the intended projection and rake, which directly influences surface finish and tool life.

Chip control and surface quality for efficient production

The one-sided chipbreaker is optimised for a wide range of cutting conditions, supporting controlled chip flow and reduced rework. A 0.4 mm nose radius balances strength and finish capability, enabling medium finishing passes with reliable geometry. The insert thickness of 3.97 mm and the rhombic outline produce a stable cutting edge resistant to chipping, which helps maintain dimensional accuracy and reduces vibration in less rigid setups. For shops seeking a compromise between productivity and surface quality, this combination increases throughput while safeguarding component tolerances.

FAQ

What materials is this insert suitable for?
The CCMT09T304 AH725 insert is specified for machining a broad range of stainless steels and steels, offering stable chip control and repeatable performance across changing workpiece materials.

How does the AH725 grade influence tool life?
The AH725 PVD-coated grade provides improved resistance to edge fracture and wear under variable conditions, which typically extends service life compared with uncoated equivalents and supports consistent productivity.

Which holder features are required for correct compatibility?
Correct compatibility depends on matching the insert form, 7° clearance angle, size and thickness to the holder, plus the correct clamping kit and fastening method; the cylindrical hole with countersink secures the insert in compatible ISO holders.

Can this insert be used for both roughing and finishing passes?
Yes, the combination of the one-sided chipbreaker and a 0.4 mm nose radius allows flexible use from medium finishing to light roughing, depending on cutting parameters and machine rigidity.

What is the exact ISO designation and thickness of the insert?
The ISO designation is CCMT09T304, with a plate thickness of 3.97 mm, rhombic form and an included cutting angle of 80°.
