CNMG 120404 T9225 — Turning insert for ISO-compliant turning, Tungaloy

A CNMG120404 T9225 ISO turning insert engineered for external and internal turning in medium-to-heavy steel machining applications.

• CVD-coated carbide for high toughness
• ISO CNMG120404 form, rhombic 80° geometry
• 0° clearance for stable engagement
• Cylindrical hole and double-sided chipbreaker

Consistent performance under variable cutting conditions

The combination of CVD-coated carbide and the T9225 grade delivers a robust universal solution for interrupted and changing cut conditions in steel turning. The coating increases resistance to abrasive wear while the carbide substrate maintains edge strength; together they extend tool life and reduce tool changes, which improves process economy. For shops facing mixed batch work, this results in fewer tool stoppages and more predictable cycle times.

Geometry tuned for repeatable accuracy and stability

The ISO CNMG120404 form with rhombic 80° seating provides a proven indexable geometry for a wide range of turning tasks. The 0° clearance reduces deflection at high feed forces, offering steadier dimensional control when machining medium-to-heavy sections. Using an ISO-standard insert also simplifies holder selection and inventory management, ensuring compatibility with common external holders and boring bars.

Practical features that ease setup and chip control

Built with a double-sided chipbreaker and a cylindrical hole, this insert allows secure clamping and effective chip formation across varied feeds and depths. The plate thickness of 4.76 mm and a small 0.4 mm corner radius support fine surface finishes without compromising strength, while the reversible design yields cost-effectiveness through indexable use. For operators new to inserts: a chipbreaker shapes chips to prevent tangling and to protect the workpiece finish.
