CNMG120404 T9225 CNMG ISO turning insert by Tungaloy — CVD-coated carbide, rhombic, 0.4 mm

A CNMG120404 T9225 indexable turning insert engineered for medium to heavy steel machining, offering ISO compatibility for standard external holders and predictable chip control.

• CVD-coated carbide grade T9225
• ISO rhombic insert for turning
• 0.4 mm corner radius for versatile profiles
• Double-sided chipbreaker, cylindrical hole

Reliable metal removal and predictable productivity

The insert’s CVD-coated surface and the T9225 grade deliver a balance of wear resistance and toughness that supports steady metal removal in mixed cutting conditions. As an indexable insert, it reduces machine downtime because edges can be indexed rather than replaced entirely, supporting continuous production runs. The coating improves flank and crater wear behaviour, which helps maintain dimensional accuracy and contributes to consistent component quality over longer tool life.

Geometry designed for standard holders and repeatable set-up

The ISO rhombic geometry ensures compatibility with a wide range of external holders when form, clearance, tolerance class, fastening method, size and thickness are matched. The rhombic plate form together with the cylindrical hole and standard fixing expects straightforward clamping and repeatable positioning in typical turning assemblies. A 0.4 mm corner radius supports versatile profile work, enabling a good mix of finishing and moderate roughing operations without frequent tool changes.

Grade and chip control that reduce interruptions

The combination of the carbide substrate and the double-sided chipbreaker targets effective chip formation for steel applications, improving machine uptime and operator safety. With a plate thickness of 4.76 mm and an included angle of 80°, the insert offers mechanical stability under interrupted cuts and variable engagement. This configuration from Tungaloy is intended to ensure process stability and predictable edge life in medium to heavy steel turning, lowering the frequency of interventions and contributing to overall production economy.

FAQ

What holder compatibility is required for this insert?
The CNMG120404 T9225 indexable insert is ISO-formatted, so compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness of the chosen external holder; select a matching ISO CNMG pocket or consult machining specialists.

For which materials is this grade most suitable?
The T9225 CVD-coated carbide grade is designed as a robust universal sort for medium to heavy steel machining, offering increased toughness for variable engagement and lightly interrupted cuts.

How does the double-sided chipbreaker affect tool economy?
A double-sided chipbreaker allows both sides to be used, effectively doubling available cutting edges per insert and helping to reduce tooling costs while maintaining consistent chip control.

What are the key dimensions to check before fitting the insert?
Check the plate size (12 mm), plate thickness (4.76 mm), corner radius (0.4 mm), included angle (80°) and whether the holder supports a cylindrical hole fixing.

Is the insert suitable for finishing and moderate roughing?
Yes — the 0.4 mm corner radius and the T9225 grade provide a compromise between surface finish capability and toughness for moderate roughing.
