CNMG090404 T9225 ISO turning insert — turning application — Tungaloy

The CNMG090404 T9225 is an ISO rhombic turning insert designed for medium to heavy steel machining with a robust CVD-coated carbide grade for interrupted or variable cutting conditions.

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

Consistent cutting performance for demanding turning

The CNMG090404 T9225 insert delivers consistent cutting performance through its CVD-coated carbide substrate, engineered for stable chip formation and extended edge life in medium to heavy steel work. The coating reduces adhesion and wear at the cutting edge, which translates to fewer tool changes and a smoother production flow. Compatibility with ISO holders is determined by form, relief angle, tolerance class, fastening method, size and thickness, so matching the insert to an appropriate external holder or boring bar ensures predictable results and reduced set-up time.

Easy integration and predictable tool life

Designed as a double-sided, indexable insert the component offers two usable cutting edges, improving cost efficiency per edge and simplifying inventory. The 0.4 mm corner radius enhances edge robustness and dampens vibration, which is particularly beneficial when turning with interrupted cuts or variable engagement. The rhombic shape with an 80° included angle provides a balance between strength and accessibility in shoulder and profiling operations. For clarity: a corner radius increases edge strength and surface finish potential, while a CVD coating is a thin, hard layer applied by chemical vapour deposition to protect the substrate during high-temperature cutting.

Practical guidance for selection and application

For external and internal turning choose the chipbreaker style and grade to match the material, machining stability and desired surface finish. The double-sided chipbreaker supports reliable chip control across a range of cutting conditions, but the final choice should account for rigidity of the set-up and feed rates. Production engineers and workshop machinists will appreciate the insert’s adaptability: it suits medium–heavy steel where a balance of toughness and wear resistance is required. When in doubt, confirm holder form and clamping details to preserve cutting geometry and repeatability.

FAQ

What materials is this insert suitable for? The CNMG090404 T9225 insert is optimised for medium to heavy steel machining and performs well under slightly interrupted cuts where additional toughness is required.

Will this insert fit ISO holders? Yes — the insert follows ISO geometry, but compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; matching those parameters ensures correct seating and secure clamping.

What does the grade T9225 mean for cutting performance? Tungaloy’s T9225 is a CVD-coated carbide grade offering a robust universal performance for steel: good wear resistance combined with enhanced toughness for variable cutting conditions.

How many cutting edges are available per insert and how is it clamped? This is a double-sided indexable insert providing two cutting edges; it is secured via a cylindrical hole and the appropriate clamping kit or screw per ISO standards — check mount compatibility before use.
