TNMG160412 T505 indexable turning insert by Tungaloy — for turning cast iron

TNMG160412 T505 is a triangular, ISO-standard indexable insert designed for external and internal turning in cast iron and similar materials

• CVD-coated cemented carbide grade T505
• Optimised for cast iron machining
• 60° triangular insert, 1.2 mm nose radius
• Double-sided chipbreaker, cylindrical hole

Dependable ISO compatibility for predictable tool changeovers

The insert follows the ISO 160412 designation and is manufactured to match common holder interfaces; compatibility is defined by insert form, clearance angle, tolerance class, fastening method, size and thickness. This ensures straightforward replacement and interchangeability in production lines where downtimes are costly. The CVD coating on the cemented carbide substrate increases wear resistance and thermal stability, extending edge life under typical turning speeds for cast iron and improving process reliability.

Stable chip control and surface finish for efficient turning

Equipped with a double-sided chipbreaker and a 1.2 mm nose radius, the insert supports controlled chip formation and a consistent cutting edge geometry. The chipbreaker design reduces irregular chips and helps maintain a predictable cutting force, which is particularly advantageous when encountering interrupted cuts or variable workpiece rigidity. The combination of the 60° triangular shape and the nominal 0° clearance angle provides a balance between strength and accessibility to the cutting zone, delivering improved surface quality and reduced need for rework.

System-oriented design for flexible workshop integration

The insert is part of an indexable system composed of the insert, a matched external holder or shank, a support shim or clamp set and replacement screws. Selection of the appropriate chipbreaker and grade should be guided by workpiece stability, desired cutting speed and the specific cast iron grade. For typical turning operations the TNMG160412 T505 insert fits standard holders and offers a practical solution where a cost-effective, long-running tool is required.

FAQ

What materials is this insert intended for? This TNMG160412 T505 indexable insert is designed primarily for machining cast iron; the CVD coating and the T505 grade suit a broad range of grey and nodular cast irons.

How does the chipbreaker affect performance? The double-sided chipbreaker on the TNMG160412 T505 improves chip control and cutting stability, which helps maintain consistent surface finish and reduces the risk of built-up edge during turning.

Is this insert compatible with standard ISO holders? Yes, the insert follows the ISO 160412 specification and is compatible with holders that accept TNMG inserts, provided the holder matches the form, fastening and tolerance requirements.

What advantages does the 1.2 mm nose radius provide? A 1.2 mm nose radius increases edge strength and smooths the cut, offering improved tool life and better surface finish in typical turning operations.

Can this insert be used for interrupted cuts? The T505 grade combined with the robust geometry and chipbreaker makes the insert suitable for many interrupted cutting scenarios, though selection should consider workpiece rigidity and cutting parameters.
