CNMM 120412 T9225 — ISO turning insert, rhombic 80° by Tungaloy

The CNMM120412 T9225 is an ISO-standard turning insert designed for medium to heavy steel turning, offering robust chip control and secure mounting for stable production.

• CVD-coated universal carbide
• 80° rhombic geometry
• 1.2 mm rounded cutting edge
• Cylindrical mounting hole for stability

Consistent performance for medium to heavy steel turning

The combination of a CVD-coated carbide substrate and the T9225 grade provides a dependable balance of wear resistance and toughness, making this insert well suited to medium to heavy steel turning. The coating resists abrasive wear while the substrate absorbs impacts during slightly interrupted cuts, which reduces the frequency of tool changes and supports continuous production. For buyers seeking predictable tool life and fewer stoppages, the coated carbide formulation improves cutting-edge stability and contributes to lower overall process costs through extended intervals between indexings.

Secure fit and geometry that simplifies setup

Compatibility with holders is determined by form, relief angle, tolerance class, fastening method, size and thickness. The rhombic 80° form gives a strong cutting edge suitable for both external and internal turning, while the cylindrical hole enables precise seating and repeatable clamping. Key dimensions such as the 4.76 mm plate thickness, 12 mm inscribed circle and 0° relief angle support robust mounting in standard ISO toolholders. The 1.2 mm corner radius provides an effective compromise between edge strength and surface finish, helping to maintain dimensional accuracy on heavier cuts without sacrificing edge life.

Improved productivity through targeted chip control and grade choice

This insert features a single-sided chipbreaker designed for predictable chip formation when matched to appropriate cutting parameters and workpiece materials. Selecting the correct chipbreaker and the T9225 sort allows optimisation for interrupted cuts and variable engagement conditions, leading to fewer tool interventions and higher throughput. Use with a stable toolpost and appropriate feeds to exploit the insert's strength; the geometry supports stronger cutting depths while maintaining surface integrity. The result is more productive turning cycles and consistent part quality, particularly where varying cutting conditions demand a tougher, more forgiving grade.
