CCMT 09T304 AH8005 Tungaloy indexable insert for Turning — PVD‑coated carbide, 0.4 mm radius

A CCMT 09T304 AH8005 rhombic indexable insert engineered for stable external and internal turning of heat‑resistant alloys and hard materials, designed to work in ISO‑compliant clamping systems.

• PVD-coated carbide grade AH8005
• 0.4 mm corner radius for fine profiles
• 7° clearance angle, 80° approach
• Rhombic CCMT form with centre hole

Productive wear resistance for demanding materials

The combination of PVD-coated surface treatment and carbide substrate in this indexable insert provides enhanced wear resistance during continuous turning of heat‑resistant alloys and higher‑strength workpieces. The AH8005 grade is developed for stable machining conditions where edge integrity and tool life are critical; this translates into fewer indexings and reduced tool change frequency, improving overall process economy. For operators, the practical benefit is consistent performance under elevated temperatures and abrasive conditions, meaning more reliable cycle times and predictable maintenance intervals.

Controlled geometry for consistent part finish

A 0.4 mm corner radius and 7° clearance angle combine to deliver a balance between cutting edge strength and surface integrity. The moderate radius supports fine profile definition while reducing the risk of edge chipping on interrupted cuts; the clearance angle prevents rubbing and heat buildup at the flank. The 80° approach (lead) angle inherent to the CCMT form assists in producing stable cutting forces for external and internal turning operations. These geometric choices contribute directly to improved surface finish and repeatability on turned components.

ISO compatibility and clamping system integration

Belonging to the ISO‑standard series of turning inserts, the plate integrates into a conventional system comprising an insert, a matching external holder or boring bar, a locating shim/clamping set and replacement screws. Compatibility is determined by form, clearance angle, tolerance class, fastening style, size and thickness; the CCMT format with a central hole and single‑side countersink (40°–60°) ensures secure clamping for torque transmission and repeatable positioning. Selecting the appropriate chipbreaker and grade to match workpiece material and machine‑tool stability optimises chip control and tool life.

Operational advantages and recommended uses

The one‑sided chipbreaker and the PVD surface make this insert especially suitable for turning operations where consistent chip formation and good edge life are needed. Typical applications include external finishing and semi‑finishing as well as certain internal turning tasks on heat‑resistant alloys and harder steels. The insert’s design supports productive, repeatable machining in stable set‑ups, reducing downtime and enhancing throughput.

FAQ

What materials is this insert suitable for?
The CCMT 09T304 AH8005 insert is intended for turning heat‑resistant alloys and harder materials; the AH8005 grade and PVD‑coating support wear resistance in these applications.

How is the insert clamped in the holder?
The insert features a central hole and a single‑side countersink (40°–60°) for secure clamping in compatible ISO holders, with the CCMT form ensuring correct positioning.

What does the 0.4 mm corner radius affect?
A 0.4 mm radius increases edge strength and helps produce better surface finish while minimising the risk of chipping on interrupted cuts compared with sharper radii.

Is the chipbreaker suitable for roughing or finishing?
The one‑sided chipbreaker is optimised for controlled chip formation under stable cutting conditions; selection between roughing and finishing depends on holder rigidity and cutting parameters.

Can this insert be used for internal boring?
Yes — the CCMT rhombic form and 80° approach angle permit certain internal turning operations, provided a suitable boring bar and stable set‑up are used.

Which holder tolerances are required for compatibility?
Compatibility is governed by insert form, free angle, tolerance class, fastening style, size and thickness; use ISO‑compliant holders matched to CCMT 09T304 dimensions for best results.
