CNMG120412 T9225 ISO turning insert for turning — Tungaloy

The CNMG120412 T9225 is an indexable turning insert optimised for medium to heavy steel turning, offering a robust universal grade and ISO CNMG geometry for reliable production use

• CVD-coated carbide grade T9225
• ISO CNMG120412 rhombic geometry
• 1.2 mm corner radius for durable cutting
• Double-sided chipbreaker with cylindrical hole

High-performance grade for variable steel turning

The insert is made from CVD-coated carbide, specifically the T9225 grade, which is formulated to balance toughness and wear resistance for demanding work on medium to heavy steel. This composition reduces premature flank wear under fluctuating engagement conditions and during lightly interrupted cuts, so process stability is improved and tool change frequency is reduced. The result is a measurable improvement in productivity where consistent cycle times and repeatable surface finish are required.

Precision geometry for secure clamping and repeatable results

Designed to the ISO CNMG120412 form, the insert’s rhombic form and 80° cutting angle provide strong edge support and versatile clearance. Key dimensions such as the 1.2 mm corner radius, 4.76 mm thickness and the 12 mm inscribed circle ensure correct seat contact and stable cutting forces when used with compatible holders. The insert features a cylindrical hole and a double-sided chipbreaker, enabling economical indexing and straightforward clamping; compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness.

Application advice and the benefit to production workflows

For turning operations where varying engagement or interrupted cuts occur, selecting this robust universal grade minimises edge chipping and maintains surface quality with fewer interventions. The double-sided chipbreaker supports consistent chip control across a range of feeds, while the insert’s geometry supports both external and internal turning tasks. When paired with the appropriate holder and correct mounting practice, the component contributes to lower total tooling costs through extended life and reliable repeatability in serial production.
