CNMG 120408 T9225 Turning insert by Tungaloy — CVD-coated carbide, 0.8 mm radius

The CNMG120408 T9225 is an ISO-compliant indexable turning insert engineered for medium to heavy turning of steel, offering a balance of toughness and wear resistance for interrupted and variable cuts

• ISO-compliant CNMG geometry
• CVD-coated carbide grade T9225
• Double-sided with cylindrical hole
• 0.8 mm corner radius for robust profile

Stable, high-productivity turning with consistent tool life

The CNMG indexable insert is designed to provide stable cutting in industrial turning applications. The CVD-coated carbide substrate of grade T9225 offers a controlled compromise between hardness and toughness, making it suitable for medium to heavy steel machining where cut interruptions or variable engagement occur. The insert’s geometry, including an 80° lead angle and a 0° rake, contributes to predictable force distribution and reduced chatter, which in turn supports longer intervals between insert changes and a reliable production rhythm.

Geometry and chip control that reduce rework and downtime

This rhombic insert features a 0.8 mm corner radius and a double-sided chipbreaker, which combine to deliver improved surface finish and chip formation across a range of depths of cut. The presence of a cylindrical hole enables secure clamping and repeatable positioning in compatible holders; the ISO-standard form and tolerance class ensure interchangeability within standard tooling systems. As a result, the tooling system achieves fewer interruptions for adjustment, less rework and a more predictable throughput in serial production.

Material scope and practical cutting behaviour explained

The T9225 grade is a robust universal grade optimised for steels, balancing wear resistance with fracture toughness. In practice this means consistent performance when turning non-alloyed and alloyed steels under mixed cutting conditions; the insert resists edge chipping and maintains cutting geometry for longer tool life. For users less familiar with coatings, CVD coating provides a hard, uniform layer that reduces flank wear and improves thermal resistance during continuous cuts, thereby extending usable lifetime compared with uncoated grades.

Integration into tooling systems and recommended use cases

The insert is part of the ISO turning insert series and requires a compatible CNMG holder, correct clamping set and matching screw geometry for safe operation. Typical applications include external and internal turning where process reliability and straightforward insert replacement are priorities. Selecting the appropriate chipbreaker and grade according to workpiece stability and the required surface quality will yield the best results; the insert’s universal character simplifies inventory while still delivering performance in demanding machining tasks.

FAQ

What applications suit this insert best?
This CNMG120408 T9225 indexable turning insert by Tungaloy is intended for medium to heavy turning of steel where intermittent cuts or variable engagement demands a tough, wear-resistant grade.

Is the insert compatible with standard CNMG holders?
Yes, the insert follows ISO geometry; compatibility depends on form, relief angle, tolerance class, clamping and size—use holders specified for CNMG 120408 inserts.

Which materials can be machined with this grade?
The T9225 CVD-coated carbide grade is optimised for steels and performs well in alloyed and non-alloyed steel turning under mixed cutting conditions.

How does the double-sided chipbreaker help production?
The double-sided chipbreaker delivers repeatable chip control and extends usability by providing two cutting edges per insert, improving process uptime and cost-efficiency.
