CNMG 160612 T5125 — Tungaloy turning insert, CVD-coated carbide, ISO CNMG form

CNMG160612 T5125 is a rhombic ISO turning insert designed for external and internal turning, optimised for interrupted cuts and less stable machining conditions.

• CVD-coated carbide grade T5125
• ISO CNMG shape with 80° cutting angle
• Suitable for cast iron and interrupted cuts
• Cylindrical hole fixation, double-sided chipbreaker

Consistent performance where interruptions occur

The insert delivers stable cutting even when machining interrupted surfaces, thanks to its CVD-coated carbide substrate and a tougher grade designed for cast iron applications. The CVD layer improves wear resistance while preserving edge integrity, which translates into fewer indexing cycles and predictable tool-life behaviour. For production environments with variable clamping or sporadic engagement, the combination of corner radius 1.2 mm and a robust grade reduces the risk of chipping and supports steady cycle times.

Proven geometry for accurate fitting and repeatability

ISO standardisation of the CNMG form ensures straightforward compatibility with a wide range of holders; the insert’s 80° cutting angle and 0° clearance are matched to common external holders and boring bars. The cylindrical central hole enables secure fixation and accurate repeatability when replacing inserts, while the double-sided chipbreaker provides two effective cutting edges per index. These features make the insert suitable for shops that prioritise process reliability and simplified tool inventory management.

Efficient chip control and surface result for cast iron

The selected T5125 grade is formulated to handle cast iron under interrupted cutting conditions, balancing toughness and wear resistance. The integrated chipbreaker allows controlled chip formation, reducing risks of entanglement and improving surface finish on ferrous materials. By aligning grade and chipbreaker to workpiece material and stability, the insert supports higher effective machining rates and can reduce secondary operations for finishing.

Practical selection and application advice for workshops

When choosing an insert for turning tasks, consider holder fit, workpiece material and stability of the setup. The CNMG ISO geometry is versatile for both external and internal turning; pair the insert with a matching ISO-compatible holder, ensure correct clamp torque and verify the clearance angles. For interrupted cuts or less rigid setups, prefer the tougher grade and a moderate feed to exploit the insert’s improved edge strength without sacrificing chip evacuation.

FAQ

What materials is this insert best suited for?
The CNMG 160612 T5125 insert is formulated primarily for cast iron work, especially under interrupted cutting or less stable conditions, where toughness and chip control are crucial.

How does the CVD coating affect performance?
The CVD coating on the T5125 grade enhances wear resistance while maintaining edge toughness, improving tool-life stability during varying engagement and interrupted cuts.

Is this insert compatible with standard CNMG holders?
Yes, the insert follows ISO CNMG dimensions and secures via a cylindrical hole, ensuring compatibility with commonly used ISO CNMG external and internal holders.

Can the insert be used for finishing passes?
The insert can achieve good surface results with proper feed and speed, but final finishing may require a dedicated grade or geometry depending on tolerance and surface roughness requirements.

How many cutting edges are available per insert?
The double-sided chipbreaker design provides two usable cutting edges per indexed position, enabling efficient reuse and economical performance.
