CNMG 190612 T9225 Turning indexable insert — Tungaloy

CNMG 190612 T9225 is an ISO-format turning indexable insert designed for external and internal turning, offering a universal grade for challenging steel applications

• CVD-coated carbide T9225 for robust performance
• ISO-compliant rhombic insert, 80° geometry
• 1.2 mm nose radius for balanced finish and strength
• Double-sided chipbreaker, cylindrical mounting hole

Consistent cutting performance with a wear‑resistant grade

The T9225 grade is a CVD-coated carbide developed for reliable use in medium to heavy steel machining where varying engagement or light interruptions demand extra toughness. The coating gives improved resistance to flank wear and maintains a stable cutting edge under fluctuating conditions, which translates into longer uninterrupted production runs and fewer tool changes. As a result, the insert supports predictable component quality and smoother process planning for serial turning applications.

Predictable mounting and system compatibility for repeatable results

Manufactured to ISO dimensions, the insert ensures compatibility with standard turning holders; coupling depends on form, free rake angle, tolerance class, fastening method, size and thickness. The plate’s cylindrical hole and standard tolerance allow secure clamping and straightforward replacement within a typical holder–shim–screw system. This standardisation reduces setup time, simplifies inventory management and improves repeatability across different machines and operators, supporting lean shopfloor practices.

Geometry engineered for stability and surface quality

The rhombic plate form with an 80° included angle and a 1.2 mm nose radius balances cutting strength and surface finish. A 6.35 mm plate thickness provides rigidity under heavy radial loads, while the double-sided chipbreaker facilitates controlled chip formation and evacuation, lowering the risk of chatter and improving surface integrity. Together, these geometric attributes reduce vibration, extend edge life and help achieve consistent component tolerances with fewer reworks.

Practical application guidance and efficient edge economy

Designed for turning, the insert is suitable for both external and internal operations in steel when the chipbreaker and grade match the workpiece and cutting conditions. The double-sided design delivers two usable edges per side, improving cost-efficiency per cutting edge and simplifying inventory rotation. For interrupted cuts or variable engagement, select the T9225 grade and a robust holder with the correct shim and screw specification to benefit from the insert’s toughness and maintain dimensional stability across batches.

FAQ

What materials is this insert optimised for?
The CNMG 190612 T9225 insert is optimised for medium to heavy steel machining; the T9225 CVD-coated carbide provides toughness for variable engagement and lightly interrupted cuts.

Is the insert compatible with standard ISO holders?
Yes. The insert follows ISO dimensions; compatibility depends on form, free rake angle, tolerance class, fastening and thickness, so use matching ISO holders and shims for secure clamping.

How does the double-sided chipbreaker benefit production?
The double-sided chipbreaker offers controlled chip formation on both usable edges, improving evacuation and reducing the likelihood of built-up edge, which supports stable cutting and longer on-tool life.

What does the 1.2 mm nose radius mean for surface finish?
A 1.2 mm nose radius provides a compromise between edge strength and surface quality: larger radius improves finish and load distribution, while maintaining acceptable cutting forces for many turning tasks.

Can the insert be used for interrupted cuts?
Yes; the T9225 grade was developed for robust, universal performance and is suitable where occasional interruptions or changing engagement demand added toughness.
