CNMG120412 AH110 — Turning insert (ISO CNMG 120412), rhombic 80°, PVD-coated carbide by Tungaloy

The CNMG120412 AH110 is an ISO-standard indexable insert for external and internal turning, designed where a sharp cutting edge and high process reliability are required

• ISO-standard CNMG form, 80° rhombic
• PVD-coated carbide AH110 grade
• 1.2 mm corner radius for robust edges
• Double-sided insert with cylindrical hole

Consistent cutting performance for steady production

The CNMG120412 AH110 insert delivers wear resistance and edge stability through its PVD-coated carbide composition and the AH110 grade. The coating supports a sharp, durable cutting edge that reduces flank wear and maintains surface quality over longer tool life; this translates into fewer tool changes and steadier cycle times. The 80° rhombic geometry combined with a 1.2 mm corner radius provides a balance between strength and versatility, enabling reliable performance under varying cutting conditions while keeping vibration and edge chipping to a minimum.

Easy integration into ISO turning systems for operational efficiency

Compatibility with standard ISO holders is ensured by the insert’s form, thickness and mounting style; the cylindrical locating hole and standard dimensions make it straightforward to fit into existing toolstocks and clamping sets. The double-sided design effectively halves tooling expenditure per cutting edge and simplifies inventory management. Clear, ISO-based specifications reduce setup time and support predictable results in production environments that depend on repeatability and minimal downtime.

Chip control and grade selection to match application demands

The double-sided chipbreaker geometry is optimised for general turning tasks where a predictable chip form and controlled evacuation are required. Choose the chipbreaker and grade combination according to workpiece stability and machining parameters: the AH110 grade is specifically engineered for a sharp cutting edge with improved resistance to chipping, making it suitable when process security is a priority. For tailored recommendations on chip control or to match the insert to specific holder types and machining strategies, technical consultation is available to align the insert selection with production goals.

FAQ

What materials is this insert intended for? The CNMG120412 AH110 insert is a general-purpose indexable insert; the AH110 grade and PVD coating are optimised for applications requiring a sharp cutting edge and consistent process security.

Can this insert be mounted in standard CNMG holders? Yes, the insert follows ISO CNMG dimensions and features a cylindrical locating hole, enabling compatible mounting in standard CNMG external holders and boring bars.

How many usable cutting edges does the insert provide? The insert is double-sided; each side offers usable cutting edges, reducing per-edge tooling costs compared with single-sided alternatives.

Does the AH110 grade offer improved resistance to chipping? The AH110 grade is specified for wear and fracture resistance while maintaining a sharp edge; this supports process reliability under demanding turning conditions.

What corner radius should be selected for finishing versus roughing? The CNMG120412 comes with a 1.2 mm corner radius, which provides a compromise between edge strength and surface finish; smaller radii are typically chosen for finer finishing, larger radii for heavy cuts.
