CCMT 09T304 T515 Tungaloy indexable insert — ISO turning insert for cast iron, 80° rhombic geometry

The CCMT09T304 T515 Tungaloy indexable insert delivers a robust solution for external and internal turning of cast iron, combining a wear‑resistant CVD coating with an economical cutting grade for stable, productive machining.

• CVD‑coated carbide for wear resistance
• Optimised for cast iron machining
• Rhombic 80° geometry for versatile turning
• Single‑sided chipbreaker with centre hole

High productivity for cast‑iron turning

The combination of a CVD‑coated carbide substrate and the T515 grade provides an optimal mix of wear resistance and cutting economy when machining cast iron. The coating reduces flank and crater wear at typical cutting speeds, which extends tool life and lowers per‑part costs. Selecting a matching chipbreaker and the correct stability class enables a predictable process, meaning fewer interruptions and a steadier production flow.

Reliable geometry that simplifies holder selection

The 80° rhombic geometry with a 0.4 mm corner radius and a 7° relief angle offers versatility for a range of turning tasks, from light finishing passes to more demanding semi‑roughing. The indexable insert is ISO‑compliant, so compatibility with holders is determined by form, relief angle, tolerance class, fixation, size and thickness. The central cylindrical hole with a single‑side countersink (40°–60°) ensures secure clamping and quick index changes, reducing downtime at the machine.

Consistent surface quality and edge stability

A small corner radius such as 0.4 mm helps achieve tighter surface finishes without compromising edge strength when paired with the T515 cutting grade. The single‑sided chipbreaker controls chip formation in interrupted and continuous cuts, improving chip evacuation and reducing the risk of built‑up edge on the cutting face. For applications requiring repeatable surface integrity, this combination supports stable process windows and consistent part tolerances.

Practical guidance for process optimisation

When integrating the insert into production, choose a holder and seating that match the ISO form and tolerance to ensure proper chipflow and clamping. For interrupted cuts or unstable setups, favour a more robust clamping and consider a slightly reduced feed to protect the corner radius. In stable conditions, the CVD coating and grade enable higher cutting speeds and longer tool life, improving throughput and lowering overall machining costs.

FAQ

What materials is this insert suitable for?
The CCMT09T304 in T515 grade is primarily optimised for cast iron machining; its CVD coating and carbide substrate make it effective for abrasive grey and nodular cast irons.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm radius balances edge strength with surface finish, delivering improved part appearance while maintaining resistance to edge chipping under moderate loads.

What does the hole and countersink configuration provide?
The central cylindrical hole with a single‑side countersink (40°–60°) enables secure and repeatable clamping in compatible holders, simplifying indexing and reducing setup time.

Is the insert compatible with standard ISO turning holders?
Yes — the insert follows ISO geometry for rhombic turning plates; compatibility depends on matching holder form, relief angle, tolerance class, fixation, size and thickness.

Which product code should be referenced when ordering?
Order using the manufacturer article number 6739798 or SKU 6739798‑Tungaloy to ensure the correct CCMT09T304 T515 Tungaloy indexable insert is supplied.
