CCMT09T308 AH120 turning insert by Tungaloy — PVD-coated carbide, 0.8 mm radius

CCMT09T308 AH120 is an indexable turning insert designed for external and internal turning where a sharp cutting edge and high process security are required.

• PVD-coated carbide AH120
• 0.8 mm corner radius
• Rhombic ISO size 09
• Single-sided chipbreaker with hole

Increased productivity through consistent cutting performance

The PVD-coated AH120 cutting grade is optimised for wear resistance and fracture toughness, delivering stable chip formation and extended tool life in turning operations. The combination of the carbide substrate and thin, robust coating reduces flank wear and supports predictable tool change intervals, which contributes directly to higher uptime on production lathes. By selecting this grade, process planners achieve a measurable improvement in repeatability and a reduction in unplanned stoppages, especially in medium-duty turning tasks.

Robust geometry for reliable machining and clamping

With a 0.8 mm corner radius, a 7° relief angle and an 80° included angle, the insert geometry balances edge strength and versatility for both finishing and light roughing. The rhombic form in ISO size 09 together with the cylindrical hole and one-sided countersink (40°–60°) ensures secure location in compatible ISO holders and straightforward assembly with standard clamping sets. The single-sided chipbreaker is matched to the grade to promote consistent chip control and surface quality while maintaining cutting-edge stability.

Practical application guidance and material suitability

Designed specifically for turning, the indexable plate suits both external and internal operations when matched to an appropriate holder and cutting parameters. The PVD-coated carbide is particularly effective where a sharp cutting edge and process safety are priorities; it performs well across a wide range of steels and is recommended when predictable wear behaviour and reduced edge chipping are required. For best results, pair the insert with a holder that matches the form, tolerance class and thickness (3.97 mm) and choose cutting data aligned with the insert’s chipbreaker and the workpiece material.

FAQ

What materials is this insert suitable for?
The CCMT09T308 AH120 insert is specified for turning and the PVD-coated AH120 grade provides wear resistance and edge strength suitable for a broad range of steels and general turning applications.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge robustness compared with finer radii, improving resistance to chipping during interrupted cuts while still allowing reasonable surface finish in finishing operations with the CCMT09T308 insert.

Which holder features are required for secure clamping?
A compatible ISO turning holder that matches the rhombic form, thickness (3.97 mm), tolerance class and the insert’s hole style is required for secure clamping of the CCMT09T308 AH120 plate.

Can this insert be used for internal turning?
Yes, the design and geometry of this indexable insert make it suitable for both external and internal turning when the correct holder and cutting data are used.

What advantages does the AH120 grade provide in production?
The AH120 grade delivers a balance of wear resistance and fracture toughness, supporting stable chip formation, extended tool life and consistent results in turning operations.
