CNMG 090404 T9225 indexable turning insert — CVD-coated carbide, 80° rhombic (Tungaloy)

CNMG090404 T9225 is an ISO-standard indexable turning insert designed for external and internal turning where toughness and reliable chip control are required

• Robust CVD-coated carbide grade T9225
• ISO CNMG geometry, 80° rhombic profile
• 0.4 mm corner radius for increased edge strength
• Double-sided chipbreaker with cylindrical hole

Prolonged tool life through a tough, wear-resistant grade

The T9225 grade combines a CVD-coated carbide substrate with a coating engineered for endurance in the middle to heavy ranges of steel machining. This composition increases resistance to flank and crater wear and, in practice, leads to extended tool life and fewer insert changes in mixed or slightly interrupted cutting conditions. For operations where engagement depth and entry conditions vary, the greater toughness of this grade helps maintain edge integrity, reducing rework and supporting a more predictable production rhythm.

Geometry and edge form that balance strength and finish

The CNMG090404 form with an 80° included angle and a 0.4 mm corner radius is specified to provide an advantageous mix of radial support and cutting-edge strength. The rhombic plate shape distributes forces evenly at the cutting edge, while the double-sided chipbreaker assists stable chip formation over a range of feeds, supporting consistent surface quality. The cylindrical hole enables secure clamping in standard ISO holders, and the 4.76 mm plate thickness contributes to overall rigidity — all factors that help reduce vibration and improve dimensional consistency.

System compatibility and practical selection guidance

As an ISO-standard indexable insert, this CNMG090404 variant fits a wide range of external holders and boring bars; the complete system typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamp set and spare fixing screws. Selection of chipbreaker and grade should be aligned with workpiece stability and machining strategy: the T9225 assortment is particularly suited to medium to heavy steel and intermittent cuts where resilience is more critical than ultra‑fine finishing. For users newer to insert selection, choosing a slightly more robust grade and generous corner radius will usually reduce the risk of edge failure in unstable set-ups.

FAQ

What workpieces is this insert best suited to? The CNMG090404 T9225 Tungaloy indexable turning insert is optimised for medium to heavy steel machining and performs well under slightly interrupted cuts where toughness and wear resistance are priorities.

How does the T9225 grade affect tool life? The T9225 CVD-coated carbide grade on this CNMG090404 insert provides enhanced wear resistance and edge toughness, which generally translates to longer tool life and more consistent performance in demanding turning operations.

Will this insert fit standard CNMG holders? Yes — the CNMG090404 designation is ISO-standard; the insert is compatible with standard CNMG external holders and boring bars when matched for form, clearance angle, clamping tolerance and thickness.

What benefit does the 0.4 mm corner radius deliver? A 0.4 mm corner radius on the CNMG090404 insert increases edge strength and reduces the likelihood of chipping in interrupted cuts, while still allowing acceptable surface finish at appropriate feeds.

Is the insert reversible or single-sided? The CNMG090404 T9225 is double-sided with a chipbreaker on each usable face, enabling multiple indexing positions and economical use of the insert.
