RNMG 120400 T9225 — ISO turning insert by Tungaloy

The RNMG120400-61 T9225 is an ISO-standard turning insert designed for medium to heavy steel turning where toughness and interrupted-cut resistance are required

• ISO RNMG geometry for standard holders
• CVD-coated carbide grade T9225 for toughness
• Suitable for medium to heavy steel turning
• With cylindrical mounting hole for secure fit
• Plate thickness 4.76 mm for stable cutting

Longer, more reliable cutting under variable conditions

The combination of a CVD-coated surface and a carbide substrate provides a balance of wear resistance and fracture toughness that supports extended machining cycles. The T9225 grade is tailored as a robust universal option for medium-to-heavy steel turning where changing engagement or light interruptions occur; this reduces downtime associated with frequent insert changes and helps maintain consistent component quality. By stabilising edge life, manufacturers benefit from predictable tool-change intervals and improved productivity.

Clear compatibility and secure mounting for repeatable set-ups

Designed to the ISO RNMG form, the insert fits into holders that conform to the same standard; compatibility depends on form, relief angle, tolerance class, fastening and thickness. The cylindrical mounting hole ensures a reliable clamping interface in standard outside holders or boring bars, supporting repeatable positioning and concentricity. Using standardised geometry simplifies tool inventory and makes it straightforward to match the cutting edge to the holder and workpiece demands, reducing set-up time and potential errors.

Practical material performance and application guidance

The T9225 composition combines a wear-resistant coating with a tough carbide core, making it suitable for a broad range of steels and for operations where intermittent cuts or variable feeds occur. The insert’s 4.76 mm thickness and 0° relief contribute to dimensional stability and edge support during heavier engagement. For best results, select a matching chipbreaker 61 and pair with an appropriate holder and clamping set; this approach optimises chip control and surface finish while maintaining cutting-edge security.

FAQ

What materials is this insert suitable for?
The RNMG120400-61 T9225 insert is engineered primarily for steel machining and performs well in medium-to-heavy steel turning where intermittent engagement or variable conditions demand toughness.

How does the T9225 grade influence tool life?
The T9225 CVD-coated carbide grade provides a balance of wear resistance and fracture toughness, which typically extends edge life under mixed cutting conditions and reduces unplanned tool changes.

Which holders are compatible with this ISO insert?
Compatibility follows ISO RNMG form and depends on holder geometry, relief angle, tolerance class, fastening method and thickness; the cylindrical mounting hole ensures secure clamping in compatible standard holders.
