CNMG120404 T9225 indexable insert (turning) – CVD-coated carbide, 0.4 mm radius | Tungaloy

CNMG120404 T9225 is an ISO-standard rhombic indexable insert engineered for external and internal turning, offering a robust universal grade that balances wear resistance and toughness for variable engagement conditions.

• CVD-coated carbide grade T9225
• Robust for medium to heavy steel turning
• ISO CNMG 120404 rhombic 80° geometry
• Double-sided chipbreaker, cylindrical hole

Durable grade for consistent productivity

The insert is supplied in T9225, a CVD-coated carbide grade developed for robust, universal performance in medium to heavy steel turning. This combination provides improved wear resistance from the coating and enhanced toughness from the substrate, which together reduce flank wear under variable cutting conditions. For operations with light interruptions or fluctuating chip loads, the grade helps to preserve edge integrity and extend effective tool life, lowering the frequency of indexings and insert changes. The outcome is more predictable cycle times and reduced production interruptions.

Precise geometry for reliable fit and repeatable results

The ISO designation CNMG120404 defines an 80° rhombic shape with 0° relief and a 0.4 mm nose radius, attributes that influence cutting forces, finish and tool mounting. The ISO standardisation ensures that compatibility with a holder is determined by form, relief angle, tolerance class, clamping method, size and thickness, so replacement and tool setup remain straightforward. A defined nose radius provides a balance between strength and surface finish; the smaller radius concentrates edge strength for interrupted cuts while still delivering acceptable surface quality on finishing passes.

Practical system benefits and improved chip control

Equipped with a double-sided chipbreaker and a cylindrical hole for secure clamping, the indexable insert offers practical advantages on the shop floor: reversible usability to make the most of each cutting edge, controlled chip formation for safer machining, and straightforward mounting within the standard system of holder, shim/clamping set and replacement screws. This modular approach simplifies logistics: keep a stock of compatible holders and shims to reduce downtime, and select the chipbreaker variant and grade to suit workpiece material and machine rigidity for optimised process security.

FAQ

How can compatibility with toolholders be checked?
Compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness; match these parameters on the holder to the CNMG120404 insert to ensure correct seating and secure clamping.

What advantages does the T9225 grade offer?
The T9225 CVD-coated carbide grade delivers a balance of wear resistance and toughness suitable for medium to heavy steel turning, improving edge life under variable cut conditions while maintaining consistent performance.

How does the double-sided chipbreaker affect machining?
A double-sided chipbreaker allows the insert to be indexed for fresh edges and provides enhanced chip control, which contributes to process stability, improved safety and a more consistent surface finish.

What system components are required for use?
A complete system comprises the ISO indexable insert, a matching external holder or bar, a shim/clamping set and replacement screws for secure assembly and straightforward maintenance.

Is this insert suitable for interrupted cuts?
Yes. The combination of a robust carbide substrate and the T9225 grade is designed to tolerate light interruptions and variable engagement, offering improved resistance to chipping in such conditions.
