TNMG220408 T5125 – Indexable Turning Insert, 60° (Tungaloy)

The TNMG220408 T5125 is an ISO-standard triangular indexable insert for turning, designed for machining cast iron under interrupted or less rigid conditions.

• CVD-coated carbide grade T5125
• Suitable for cast iron and interrupted cuts
• ISO TNMG 220408 triangular insert
• Double-sided chipbreaker with cylindrical hole

Consistent performance for interrupted turning

The insert’s CVD-coated carbide construction (grade T5125) provides a tougher cutting edge that maintains stable chip formation when machining cast iron in starts, stops or unstable setups. The coating enhances wear resistance and reduces adhesion, which helps to keep cutting forces predictable and tool changes less frequent. For production environments where interrupted cutting or variable clamping is common, this geometry and material pairing supports a steady cycle time and reduced scrap rates.

ISO conformity simplifies holder selection

As an ISO-standard insert, compatibility with holders depends on measurable parameters such as form, clearance angle, tolerance class, clamping method, size and thickness. The data supplied here — triangular shape, 60° included angle and 0° clearance angle — enables straightforward matching to an appropriate outside holder or boring bar. Selecting the correct chipbreaker and insert grade according to workpiece material and machine stability will produce the best surface finish and tool life while minimising set-up time.

Geometry optimised for accessibility and economy

The triangular plate form with a 0.8 mm corner radius balances edge strength and cutting access in general turning tasks. The double-sided chipbreaker combined with a cylindrical hole allows consistent clamping and the practical use of multiple indexing positions, improving cost per edge. The compact 22 mm plate size and standard hole style suit many common holders, making the insert a flexible choice for workshops that require efficient stock management and rapid tool changes.

Clear application guidance and material fit

This cutting grade is specified for turning applications and is particularly suited to cast iron where occasional interruptions or lower rigidity are present. The TNMG220408 T5125 insert brings together a robust carbide substrate and a wear-resistant coating to extend life under challenging chip formation conditions. For operators less familiar with insert selection: choose the grade for the workpiece and the chipbreaker for the cut type; consider a more rigid clamping set-up for finishing passes to enhance surface quality.

FAQ

What materials is this insert suited to?
The TNMG220408 T5125 is formulated for machining cast iron, especially where interrupted cuts or less rigid conditions occur, thanks to the T5125 carbide grade.

How does the T5125 grade affect performance?
Grade T5125 is a tougher, CVD-coated carbide designed to improve wear resistance and chip control in interrupted turning, which helps maintain consistent tool life.

What should be considered when choosing a holder?
Holder compatibility is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness; match these parameters to the TNMG220408 specification for secure clamping.

Can the insert be indexed to use multiple edges?
The plate’s double-sided chipbreaker and standard hole allow indexing to fresh edges, extending the usable life per insert and improving cost efficiency.

Is this insert suitable for finishing passes?
The TNMG220408 T5125 performs best when the appropriate chipbreaker, rigidity and feed/speed are applied; for high-quality finishing, increase setup rigidity and fine-tune cutting data.
