• For economical cast iron machining
• Cylindrical hole for secure clamping

Efficient, cost-conscious machining for cast iron components

The insert is a CVD-coated carbide grade tailored for the economic machining of cast iron, delivering a balance of wear resistance and cutting performance. The CVD layer increases surface hardness and thermal stability, which reduces flank wear and extends the tool life under typical turning conditions. For production environments where cycle time and consumable cost matter, this combination supports consistent component quality while lowering running costs.

Compatibility and secure clamping for stable turning

Compatibility with holders is defined by form, clearance angle, tolerance class, fastening, size and thickness, so the rhombic geometry and the cylindrical hole ensure reliable seating and repeatable clamping. The 0° clearance angle and the 80° approach geometry provide predictable cutting forces and chip flow, contributing to process stability. When paired with the correct outer holder, underlay or clamping set and replacement screws, the system gives reproducible results and simplifies tool management on the shop floor.

Controlled chip formation and practical grade selection

The double-sided chipbreaker design promotes controlled chips when turning cast iron, improving surface finish and reducing the risk of entanglement. Grade T505 is intended for economical applications in cast iron; selection should be based on workpiece stability, the presence of interrupted cuts and the desired cutting speed. By choosing the correct chipbreaker and insert grade, tool life and part quality can be optimised without complex parameter changes.

FAQ

What materials is this insert suitable for?
The Tungaloy CNMG120408 T505 is intended primarily for the economic machining of cast iron; selection for other materials should consider grade characteristics and machining stability.

How is compatibility with a holder determined?
Compatibility depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness; ensure the holder matches CNMG 120408 dimensions and the cylindrical hole seating.

Can this insert be used for interrupted cuts?
Grade T505 is suited to economical cast iron turning; interrupted cuts require assessment of part rigidity and cutting conditions and, if necessary, a more robust grade or altered machining parameters.

What benefit does the CVD coating provide?
The CVD coating on the cemented carbide improves wear resistance and thermal stability, reducing flank wear and extending tool life during continuous turning.

How does the double-sided chipbreaker help production?
A double-sided chipbreaker promotes controlled chip formation and improved surface finish, reducing downtime for chip removal and contributing to safer, more efficient turning operations.
