IRON ROOT ST taps, special taps for wire thread inserts, thread insert taps ST3 ST4 ST6 ST8
Straight-Flute Screw Tap for Wire Thread Inserts
This specialized tap is designed for machining internal threads when installing wire thread inserts. Also known as an "Insert Tap," it features an internal thread code of ST. For example, ST10x1.5 indicates that the tap is used to machine an internal thread for installing an M10x1.5 wire thread insert.
The straight-flute tap is characterized by its downward chip removal and excellent heat dissipation. It delivers superior performance in through-hole and shallow blind-hole machining.
Special taps for wire thread inserts (abbreviated as ST taps, thread insert taps, or threaded insert taps) are used for machining internal threads for installing wire thread inserts. Compared to ordinary taps, ST taps have a larger major diameter, pitch diameter, and minor diameter than the diameter of the thread insert.
