STI Tap (Screw Thread Insert Tap)

The STI tap, also known as a thread insert tap, is a specialized cutting tool designed for machining oversized internal threads used for helical coil thread inserts. These high-precision taps create stronger and more durable threaded connections, ensuring balanced load distribution and effectively preventing thread stripping, thereby extending the service life of components across various industries. As a core tool for precision thread processing, STI taps are widely used in applications where thread reliability and durability are critical.

Applications:
Mechanical Manufacturing: For cutting internal threads in pilot holes before installing thread inserts.
Thread Repair & Reinforcement: Used in maintenance to repair worn or damaged threaded holes in equipment.
Precision Component Machining: Suitable for threading small parts in electronics, precision instruments, and other high-accuracy applications.
