The 22ER 4API502 TP2215 external threading insert is engineered for precise, repeatable ISO metric and unified thread forms. Featuring a 60° partial profile, this insert offers excellent versatility for producing multiple pitches while maintaining consistent thread geometry and surface finish.

Manufactured from a high-performance carbide substrate and finished with a wear-resistant coating, this insert delivers reliable tool life and stable cutting performance in steel, stainless steel, and alloy materials. The AG60 chip-former promotes controlled chip evacuation and smooth cutting action, even in demanding threading operations.

Ideal for job shops and production environments where flexibility, accuracy, and durability matter.
