TNMG 220412 AH120 Drehen — Tungaloy TNMG220412 AH120 turning insert, PVD-coated carbide, 60°

TNMG220412 AH120 is an ISO-standard indexable turning insert for general turning operations, designed to deliver process security where a sharp cutting edge and reliable wear resistance are required.

• PVD-coated cemented carbide AH120
• Triangular insert, 60° cutting angle
• Corner radius 1.2 mm, double-sided chipbreaker
• Cylindrical hole, thickness 4.76 mm

Maximise productivity with a wear-resistant PVD grade

The AH120 grade is a PVD-coated cemented carbide developed for turning applications that demand a fine balance between edge sharpness and robust wear resistance. With its engineered coating and carbide substrate, this insert sustains consistent cutting performance over longer tool life, which contributes to fewer indexings and reduced downtime. For production environments where stable chip formation and repeatable surface quality matter, the combination of sharp edge geometry and the AH120 coating supports efficient cycle times and predictable component tolerances.

Easy integration into ISO-compatible tool systems

Designed to the ISO 220412 geometry, the insert ensures predictable compatibility with many standard external holders and boring bars; fitment depends on form, relief angle, tolerance class, fastening, size and thickness. The 60° cutting angle and triangular shape provide a reliable seating and accessibility for external turning, while the cylindrical hole and specified thickness of 4.76 mm deliver stable clamping. System setup typically comprises the indexable insert, a matching outer holder or boring bar, a backing pad or clamp set and replacement fixing screws, enabling straightforward assembly in existing turning tool systems.

Controlled chip flow and surface integrity for precision turning

The double-sided chipbreaker and a 1.2 mm corner radius are engineered to support consistent chip control across a range of cutting conditions, improving surface finish and reducing the likelihood of chatter or edge instability. The insert’s geometry focuses on process security: by combining a suitable chipbreaker with the AH120 grade, machinists can achieve a sharp initial cut while maintaining resistance to edge chipping. This results in fewer tool changes, more stable cycle times and enhanced repeatability on serial production parts.

FAQ

What is the AH120 grade suitable for?
The AH120 grade is a PVD-coated, wear- and chip-resistant cemented carbide formulated for turning; select the chipbreaker and grade to match the workpiece material and machining conditions when using the TNMG220412 AH120 insert.

Will this insert fit existing ISO toolholders?
Compatibility follows ISO geometry rules: the TNMG220412 insert fits ISO-standard holders that match form, relief angle, tolerance class, fastening, size and thickness.

How is the insert mounted in the tool system?
Mount the insert with a compatible external holder or boring bar, a backing pad/clamp set and the appropriate fixing screw; the system typically includes the insert seat, underlay and replacement screws for secure clamping.

Is the insert reversible or indexable?
The triangular, double-sided design provides multiple usable cutting edges that can be indexed to extend service life and maintain consistent performance.

What benefits does the PVD coating provide?
The PVD coating on this cemented carbide insert enhances wear resistance and helps preserve a sharp cutting edge, contributing to stable chip formation and improved surface finish during turning operations.
