CCMT 09T308 GH730 — Tungaloy indexable turning insert for external and internal turning

The CCMT09T308 GH730 is an ISO‑standard rhombic indexable insert engineered for general turning, providing a balance of wear resistance and edge stability for a wide range of machining tasks.

• ISO‑standard rhombic insert for turning applications
• GH730 grade for enhanced wear resistance
• 0.8 mm corner radius for fine profile work
• 7° relief angle with cylindrical hole and countersink

Consistent productivity through a wear‑resistant grade

The GH730 grade, combined with a carbide substrate, delivers improved wear resistance and stable cutting edges under continuous turning conditions. This results in fewer index changes and longer tool life compared with uncoated alternatives, supporting predictable process times and lower tooling consumption. By favouring a grade that balances toughness and abrasion resistance, manufacturers obtain measurable productivity gains when machining medium‑duty components where edge stability is critical.

Secure mounting and assured compatibility with ISO systems

The insert is designed to integrate into standard ISO tool systems: compatibility depends on form, clearance (7°), tolerance class, fastening, size and thickness. The presented insert features a cylindrical hole with a single‑side countersink (40°–60°), enabling reliable clamping in matched holders. Correct clamping reduces vibration and repeatability errors, which translates into improved dimensional conformity and a lower scrap rate in serial production.

Geometry and chip control for repeatable surface quality

A rhombic insert geometry combined with a single‑sided chipbreaker provides controlled chip formation and consistent contact conditions. The 0.8 mm corner radius offers a compromise between edge strength and the ability to achieve refined profiles and surface finish. For finishing passes the smaller radius supports finer edges; for light roughing, the same geometry maintains edge stability. Choosing the appropriate chipbreaker and cutting parameters ensures efficient evacuation of chips and a steady surface result.

System approach and practical application advice

This item is supplied as an ISO indexable insert and forms part of a system consisting of the insert, a suitable external holder or boring bar, a shim/clamping set and replacement screws. Use the CCMT09T308 GH730 where machining tasks demand reliable edge life and straightforward insert indexing. For mixed production runs, pairing the GH730 grade with a holder offering rigid support will enhance process security and repeatability without complex parameter tuning.

FAQ

What materials is this insert suitable for? The CCMT09T308 GH730 Tungaloy indexable insert is designed for general turning applications; the GH730 grade provides a balance of wear resistance and edge stability suitable for many commonly machined metals when matched with the correct chipbreaker and cutting data.

How does the hole and countersink affect clamping? The cylindrical hole with a single‑side countersink (40°–60°) on the CCMT09T308 improves seating and concentric clamping in compatible holders, reducing the risk of slippage and enhancing repeatability during high‑volume turning.

Can the 0.8 mm corner radius be used for finishing? Yes, the 0.8 mm corner radius on the CCMT09T308 supports finer profiles and improved surface finish in finishing passes while still maintaining adequate edge strength for light roughing.

Is the insert compatible with all ISO CCMT holders? Compatibility requires matching the insert shape, clearance angle (7°), tolerance class, fastening method, size (09) and thickness (3.97 mm) with the intended CCMT holder; consult holder specifications or Metav Werkzeuge for verification.

What is included in the system when planning a tool setup? A complete system typically comprises the indexable insert, a suitable external holder or boring bar, a shim/clamping set and replacement screws to ensure secure mounting and straightforward serviceability.
