TNMG160408 T5125 – ISO indexable turning insert, CVD-coated carbide, triangular 60° geometry, Tungaloy

A TNMG160408 T5125 is an ISO-indexed triangular insert intended for external and internal turning, optimised for interrupted cuts and less stable setups where a tougher grade improves productivity

• TNMG160408 geometry for ISO turning
• CVD-coated carbide grade T5125
• 0.8 mm corner radius for versatile profiles
• Cylindrical hole with screw clamping

Reliable cutting performance for interrupted turning

The combination of a CVD-coated carbide substrate and the T5125 grade provides a tougher cutting edge suited to interrupted cuts and variable rigidity. This construction promotes stable chip formation and longer tool life, which reduces downtime and tool-change frequency. The 0.8 mm corner radius supports versatile profile generation and contributes to an even wear pattern, helping to maintain consistent surface quality on cast iron components under demanding conditions.

Engineered for ISO compatibility and secure clamping

Compatibility with toolholders depends on geometry, relief angle, tolerance class, fastening and insert thickness; this insert features a triangular 60° geometry, 0° relief angle and a cylindrical hole for screw clamping, enabling predictable mounting in ISO indexable systems. The insert thickness of 4.76 mm and 16 mm size are industry-standard dimensions that simplify replacement and inventory management. System components typically include a matching external holder or boring bar, a precision shim or clamp set and replacement screws for secure retention.

Application guidance that improves throughput and reliability

Designed primarily for turning, the insert performs well in both external and internal operations where interrupted engagement or less stable set-ups occur. Select a matching chipbreaker and the T5125 sort for cast iron machining to balance wear resistance and toughness; the double-sided chipbreaker offers two cutting edges per indexation cycle, improving economy per insert. The material choice—carbide with CVD layering—helps achieve a favourable mix of edge strength and thermal resistance, resulting in reproducible process windows and fewer unexpected stops for tool changes.

FAQ

What materials is this insert suitable for? The TNMG160408 T5125 insert is a carbide indexable insert with a CVD-coated T5125 grade, recommended primarily for cast iron and similar materials, especially under interrupted cutting conditions.

How does the T5125 grade affect tool life? The T5125 sort is designed for increased toughness; in practical terms, the TNMG160408 T5125 shows improved resistance to chipping in interrupted cuts, which often translates to longer tool life and fewer unscheduled tool changes.

Is the insert compatible with standard ISO toolholders? Compatibility requires matching the insert form, relief angle, tolerance class, fastening method, size and thickness; the TNMG160408 conforms to ISO indexable dimensions and uses a cylindrical hole for screw clamping to enable predictable mounting in ISO holders.

Can this insert be used for internal boring as well as external turning? Yes, the insert is suitable for both external and internal turning operations; selecting an appropriate holder and chipbreaker ensures stability and surface finish consistency.

How many cutting edges are available per indexation? The triangular TNMG insert is double-sided with a double-sided chipbreaker, offering multiple indexable cutting edges to improve cost efficiency per insert
