CNMG 090304 T9225 turning insert by Tungaloy — CVD-coated carbide for medium-to-heavy steel turning

CNMG090304 T9225 is an ISO-format turning insert for versatile external and internal turning applications, offering robust performance where interrupted cuts or variable engagement demand higher toughness.

• CVD-coated carbide for robust steel turning
• Universal grade T9225 for interrupted cuts
• ISO CNMG 090304, 80° rhombic geometry
• 0.4 mm corner radius, double-sided insert

Increased uptime through a tough, coated grade

The combination of CVD-coated carbide and the T9225 grade delivers a balance of hardness and toughness suited to medium-to-heavy steel machining. The coating improves wear resistance at elevated cutting temperatures, which helps to maintain a consistent cutting edge and prolongs in-process life. Fewer tool changes translate into improved machine availability and lower handling time, supporting steady production cycles and predictable turnaround for batch and single-part manufacturing.

Secure mounting and standardised compatibility for fast tool changes

Designed in the ISO CNMG format, the insert fits established 80° rhombic holders when dimensions match; compatibility depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness. The 80° rhombic geometry and a 0.4 mm corner radius provide a robust contact area and a favourable cutting edge for a range of turning tasks. The central cylindrical hole with screw clamping enables firm seating in a matched holder, while the double-sided configuration doubles the effective life per insert and reduces inventory turnover.

Predictable chip control and flexible application choices

The insert’s double-sided chipbreaker design supports controlled chip formation across various depths of cut and feed rates, improving surface finish and lowering the risk of vibration under unstable conditions. Selection of the appropriate chipbreaker and grade should follow the material, cutting strategy and machine rigidity; for unstable setups, the T9225 universal grade offers additional toughness to ride through light interruptions. The reversible nature of the component makes it a cost-effective choice for job shops and production lines that require quick index changes and consistent part quality.

Practical guidance for selection and use

Ensure the chosen holder matches the ISO geometry and thickness to maintain clamping reliability and tool life. When replacing inserts, verify the tolerance class and fastening screw condition to avoid micro-movements that affect surface quality. For applications that combine high cutting speeds with interrupted cuts, choose conservative parameters initially and adjust feeds to balance tool life with productivity.

FAQ

What materials is this insert suitable for?
The CNMG090304 insert in grade T9225 is designed primarily for medium-to-heavy steel machining and performs well under slightly interrupted cuts thanks to the CVD-coated carbide composition.

How does the insert mount in a holder?
This ISO-format rhombic insert uses a central cylindrical hole and screw clamping; correct holder compatibility depends on matching form, clearance angle, tolerance class, size and thickness for secure seating.

Is the insert reversible and what is the benefit?
Yes, the double-sided indexable insert offers two usable cutting edges, which effectively doubles service life per insert and reduces replacement frequency for the workshop.

Which chipbreaker should be chosen for fine surface finish?
For improved surface finish, select a chipbreaker suited to the actual feed and depth of cut; the built-in double-sided chip control of this insert helps maintain consistent chips and surface quality under stable conditions.

How to identify the exact product?
The item is listed as CNMG090304 in grade T9225 with article number 6780734 and manufacturer SKU TUN6780734, supplied as an original Tungaloy indexable insert.
