CPMT 09T304 T505 turning insert — ISO rhombic insert for turning (Tungaloy)

CPMT 09T304 T505 is a robust ISO-standard rhombic turning insert designed for economical and productive machining of cast iron components.

• CVD-coated carbide for cast iron
• ISO-standard rhombic 09 insert
• 80° lead angle for robust turning
• Single-sided chipbreaker, with hole

Productive turning of cast iron with predictable results

The CVD-coated carbide grade T505 delivers a cost-efficient balance of wear resistance and edge stability for the machining of cast iron. The coating reduces flank wear and improves resistance to abrasive particles common in grey and nodular cast irons, which sustains cutting performance across batch runs. Choosing this insert supports consistent cycle times and a lower tool consumption rate, providing a measurable advantage in throughput for turning operations.

Secure fitting and easy integration into existing tool systems

As an ISO-standard indexable insert, the component integrates with many standard external holders and boring bars; compatibility depends on form, clearance angle, tolerance class, fixation, size and thickness. The rhombic geometry and the 80° lead angle create a stable contact with the workpiece and holder, reducing chatter in less rigid set-ups. Where interrupted cuts or varying stability are expected, pairing the insert with a suitable holder and correct clamping torque ensures repeatable results.

Designed features that simplify process planning

The insert’s single-sided chipbreaker is tuned for chip control in cast iron turning, producing short, manageable chips that help protect the tool flank and the workpiece surface. The central cylindrical hole with a single-sided countersink (40°–60°) enables secure clamping and straightforward index changes without tool re‑setting. The 0.4 mm corner radius helps balance edge strength and finish, making it suitable for a range of step‑over and finishing passes where surface integrity matters.

Practical handling, selection and economic operation

With a 3.97 mm plate thickness and the 11° clearance angle, the insert offers a combination of rigidity and accessibility for common external and internal turning tasks. For efficient process selection, match the chipbreaker and the T505 grade to the component’s stability and the targeted cutting speed: the grade is intended for economical machining of cast iron, offering long wear life under moderate to high cutting speeds when coolant and cutting parameters are set appropriately. The overall result is fewer tool changes, improved machine uptime and easier planning for production runs.

FAQ

Is this insert suitable for interrupted cuts in cast iron?
The CPMT 09T304 T505 turning insert is designed for cast iron machining; its chipbreaker and robust grade allow handling of intermittent cuts depending on the machine and holder rigidity.

Which toolholders are compatible with this ISO rhombic insert?
Compatibility is determined by insert form, clearance angle, tolerance class, fixation, size and thickness; use holders specified for ISO rhombic 09 inserts to accommodate the CPMT 09T304 T505.

What advantages does the T505 CVD coating provide?
The T505 CVD coating on the carbide substrate improves wear resistance and edge life when turning cast iron, reducing flank wear and helping to maintain dimensional stability across longer production runs.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius offers a compromise between edge strength and achievable surface finish, suitable for semi-finish and finish passes where surface integrity and tool life must be balanced.

Can this insert be used for materials other than cast iron?
While the grade is optimised for cast iron, process engineers may use the insert for similar abrasive materials with appropriate adjustments to cutting data; selection should be based on stability, cutting speed and desired tool life.
