CCMT 09T308 AH120 – Indexable turning insert, PVD-coated carbide (Tungaloy)

CCMT 09T308 AH120 is an ISO-standard indexable insert designed for external and internal turning, offering a sharp cutting edge and high process security.

• PVD-coated carbide grade AH120
• Sharp 0.8 mm nose radius
• 7° clearance for reliable cut
• Rhombic form with cylindrical hole

Engineered for stable cutting and long life

The PVD-coated carbide grade AH120 delivers a balance of wear resistance and edge strength that supports continuous turning operations. The coating enhances surface hardness and reduces adhesive wear, while the substrate maintains fracture resistance; together these properties extend the effective tool life and reduce unexpected downtime. Specified geometry such as the 0.8 mm nose radius and the defined clearance angle (7°) contribute to a consistent cutting action, enabling stable chip formation and repeatable machining results across batch runs.

Designed to increase workshop productivity

A single-sided chipbreaker combined with the robust grade reduces rework and supports predictable tool change intervals, improving overall machine uptime. The insert’s profile and sharp edge are optimised for achieving a good surface finish with reduced cutting forces, which can lower cycle times and tool costs per component. Compatibility with ISO holders ensures quick replacement and minimal set-up time; choosing the right chipbreaker and grade for the workpiece and machine rigidity converts these technical features into measurable production benefits.

Clear mounting and dimensional data to aid selection

The insert follows ISO norms for turning plates and must be paired with a matching clamping set and holder determined by form, free angle, tolerance class, fastening method, size and thickness. Important dimensional facts include a 3.97 mm plate thickness, a rhombic 80° included angle, and a cylindrical hole with a single-sided countersink (40°–60°) for secure seating. These details simplify procurement and ensure the plate locates correctly in standard external or boring holders, avoiding instability that can compromise finish and tool life.

Practical application guidance for turning tasks

This indexable plate is intended specifically for turning applications where a sharp cutting edge and process reliability are required. The combination of PVD-coated surface and a tough carbide substrate makes it suitable for operations that demand consistent edge retention and resistance to chipping. Select the plate variant and chipbreaker that best match the workpiece material, cutting mode and machine rigidity to transform material properties into dependable production outcomes with predictable tool performance.

FAQ

What materials is this insert intended to machine?
This CCMT 09T308 AH120 indexable insert from Tungaloy is designed for turning operations where a sharp cutting edge and process security are required; select the appropriate chipbreaker and parameters to match the specific workpiece material.

How does the AH120 grade improve tool life?
The PVD-coated AH120 grade combines surface hardness with a fracture-resistant substrate, which reduces adhesive wear and chipping for longer, more predictable tool life in the CCMT 09T308 format.

Which holder features are necessary for correct mounting?
Secure mounting requires a holder that matches the rhombic form, size 09, plate thickness and the cylindrical hole plus single-sided countersink; correct tolerance class and fastening method ensure stable seating.

Is this insert suitable for both external and internal turning?
Yes, the ISO-standard geometry and the single-sided chipbreaker make the plate suitable for both external and internal turning tasks when paired with the correct holder and cutting data.

Can this insert be used on high-speed operations?
The PVD coating and the AH120 substrate provide wear resistance appropriate for demanding turning tasks; verify machine rigidity and cutting parameters to determine suitability for high-speed conditions.
