CNMG120404 T9225 turning insert — Tungaloy CVD-coated carbide for medium-to-heavy steel turning

The CNMG120404 T9225 is a CVD-coated carbide turning insert designed for ISO-compliant turning applications, offering robust cut resistance and reliable performance in varied and intermittently interrupted engagement conditions.

• CVD-coated carbide grade T9225
• Robust universal grade for steel turning
• ISO CNMG 120404 geometry, 80° included angle
• 0.4 mm corner radius, cylindrical hole

Reliable cutting performance for stable production

The insert delivers consistent tool life through a CVD-coated surface that improves wear resistance and protects the cutting edge under demanding conditions. The chosen grade is engineered as a robust universal sort for medium-to-heavy steel machining, providing abrasion resistance without sacrificing toughness. This balance reduces the frequency of insert changes and contributes to uninterrupted production cycles while maintaining dimensional stability on the workpiece.

Easy integration into ISO tool systems to reduce setup time

Designed to the ISO CNMG 120404 form, the plate matches common holders when the form, clearance angle, tolerance class, fastening, size and thickness align. The rhombic shape and cylindrical hole ensure straightforward clamping with standard top-side or dovetail holders; compatibility is determined by geometric fit rather than brand-specific tooling. Clear dimensional standards simplify inventory management and lower setup complexity, supporting faster changeovers and reproducible clamping for repeat accuracy.

Improved chip control and surface finish for safer machining

The double-sided chipbreaker and cutting-edge geometry enhance chip formation, directing swarf away from the cutting zone and reducing the risk of re-cutting or tool nose rubbing. The 0.4 mm corner radius offers a compromise between edge strength and achievable surface finish, suitable for a range of turning passes from medium finishing to more robust roughing where stability is required. Better chip evacuation and edge integrity help to maintain surface quality while supporting higher feed rates in many steel applications.

FAQ

What materials is this insert intended for?
The CNMG120404 T9225 insert is formulated as a robust universal grade for steel machining and performs well under varying engagement and lightly interrupted cuts.

Can the CNMG120404 be used for internal turning as well as external turning?
Yes, the ISO CNMG form and the plate’s geometry allow use in both external and internal turning applications when paired with an appropriate boring bar or holder.

What does the T9225 designation indicate?
T9225 denotes the CVD-coated carbide grade tuned for a balance of wear resistance and toughness, suitable for medium-to-heavy steel turning where changeable cutting conditions occur.

How does the double-sided chipbreaker benefit production?
The double-sided chipbreaker improves chip control, reduces swarf-related interruptions and contributes to safer, more continuous machining cycles and consistent surface quality.

Is special clamping hardware required for this insert?
No manufacturer-specific hardware is required; compatibility depends on matching the ISO form, fastening method, size and thickness with the chosen holder and clamping set.

Does the 0.4 mm corner radius affect surface finish?
The 0.4 mm corner radius offers a compromise between edge strength and finish quality, providing stability for heavier cuts while still enabling acceptable surface texture for many turning operations.
