CNMG 160612 AH120 – ISO turning insert for Drehen by Tungaloy

The CNMG 160612 AH120 is an ISO-standard rhombic turning insert designed for external and internal turning, offering a wear-resistant PVD-coated carbide grade for demanding machining tasks.

• CNMG160612 geometry, ISO-standard insert
• PVD-coated carbide AH120 for wear resistance
• 0° clearance angle, 80° included angle
• Double-sided with central hole for secure clamping

Consistent process security through a wear-resistant grade

The CNMG insert is supplied in the AH120 PVD-coated carbide grade, engineered for a balance of sharp cutting edge and high process security. The PVD coating reduces flank and crater wear, which translates into longer effective tool life and fewer indexings in serial production. Because the grade is optimised to resist both wear and chipping, operators benefit from predictable tool behaviour during interrupted cuts and medium-to-high cutting speeds. This reliability results in reduced machine downtime and more consistent part quality.

Robust geometry for stable cutting and secure clamping

With a 1.2 mm corner radius and a plate thickness of 6.35 mm, the geometry offers a durable cutting edge that tolerates moderate cutting forces while maintaining surface finish. The insert’s 80° included angle and 0° clearance angle make it suitable for general turning profiles where strength at the cutting edge is important. The central cylindrical hole and double-sided design enable secure mounting in ISO-compatible holders and two usable cutting edges per index, improving cost efficiency per edge and simplifying inventory handling for workshops.

Application guidance and selection for optimal results

Select a double-sided chipbreaker and the AH120 grade to match alloy and process stability: this configuration is particularly appropriate when a sharp cutting edge and process security are both required. The insert is intended for turning applications and integrates into a system comprising an ISO insert, compatible external holder or boring bar, support pad or clamp set, and replacement clamp screws. For best results, pair the insert with a holder that matches form, clearance, tolerance class, clamping method, size and thickness to ensure repeatable clamping accuracy and stable cutting conditions.

FAQ

What materials is this insert suitable for? The CNMG 160612 AH120 insert is a PVD-coated carbide grade intended for turning a broad range of materials where wear resistance and edge integrity are required; choose the specific chipbreaker and cutting data to match the workpiece material.

How does the AH120 grade benefit production runs? AH120 provides improved wear and breakage resistance; in production it offers longer tool life and consistent performance, reducing the need for frequent indexing and helping to maintain dimensional stability across batches.

Can the insert be used in both external turning and internal boring? Yes, the ISO rhombic geometry and 80° included angle allow the insert to be used in compatible external turning holders and in appropriate boring bars for internal turning applications.

How many cutting edges are available per insert? The double-sided design gives two usable cutting edges; combined with secure clamping via the central cylindrical hole this enables efficient edge utilisation and reliable clamping repeatability.

Which holders are compatible with this insert? Compatibility is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness; use ISO-compatible turning holders or boring bars that accept CNMG inserts to ensure correct fit and performance.
