CNMG 120404 T9225 — ISO turning insert (Tungaloy)

The CNMG120404 T9225 is an indexable turning insert for external and internal turning, designed as a robust universal grade for medium to heavy steel machining

• CVD-coated carbide for high wear resistance
• Robust universal grade T9225 for steel machining
• Rhombic CNMG form with 80° cutting angle
• Double-sided chipbreaker with cylindrical hole

Optimised wear resistance for productive turning

The combination of a CVD-coated surface and a carbide substrate yields a coating that increases abrasion resistance while preserving toughness where it matters. This results in a cutting edge that sustains consistent performance under varying engagement conditions. For machining steel in medium to heavy cuts, the T9225 grade offers a balance between tool life and cutting stability, which reduces tool change frequency and supports steady production cycles. The CVD layer also helps maintain dimensional accuracy over longer runs, translating into lower overall machining costs and fewer interruptions to the workflow.

Secure fit and versatile geometry for reliable set-up

Compatibility with the toolholder is governed by the insert’s form, clearance angle, tolerance class, clamping method, size and thickness. The rhombic CNMG shape with an 80° cutting angle provides a good compromise between strength and accessibility in shoulder and profiling operations, while the cylindrical hole enables secure clamping in many common holders. The plate thickness of 4.76 mm and a nominal size of 12 mm contribute to rigidity at the cutting zone. These attributes make the insert suitable for standard ISO toolholder systems and simplify selection in production environments where set-up repeatability is essential.

Chip control and edge integrity for interrupted and stable cuts

A double-sided chipbreaker improves chip formation across a range of depths of cut and feed rates, delivering cleaner evacuation and less risk of entanglement. The 0.4 mm corner radius supports a controlled cutting edge that balances surface finish and edge strength, which is particularly useful where light interruptions or variable engagement occur. Together, the geometry and the robust grade provide process security: fewer edge failures, consistent surface quality and predictable wear behaviour. When combined with an appropriate holder and cutting parameters, the insert contributes to higher machine uptime and efficient throughput.

FAQ

What materials is this insert best suited for?
The CNMG 120404 T9225 insert from Tungaloy is formulated as a robust universal grade for medium to heavy steel machining and performs well where toughness is required.

How can compatibility with existing holders be checked?
Compatibility depends on the insert’s form, clearance angle, tolerance class, clamping type, size and thickness; the CNMG 120404 conforms to ISO dimensions and fits standard CNMG holders when these criteria match.

Does the CVD coating improve tool life under variable cutting conditions?
Yes, the CVD-coated carbide of the T9225 grade enhances wear resistance while retaining toughness, which supports longer tool life under changing engagement and light interruptions.

Is this insert recommended for interrupted cuts?
The T9225 grade is designed to offer extra toughness for light to moderate interrupted cuts, and the rhombic geometry combined with a 0.4 mm corner radius helps maintain edge integrity during such operations.

How is the insert fastened in the holder?
The insert is designed with a cylindrical hole for positive clamping; when paired with the correct clamping set and compatible holder, the design ensures secure fixation and repeatable positioning.
