Product information

BaerCoil HSSE Machine Tap UNC 10 x 24 STI (oversized for wire thread inserts) - PRO for through holes


BaerCoil® machine taps are mainly used for thread repair or thread reinforcement in connection with wire thread inserts. This BaerCoil® screw tap can be used to cut a finished thread with oversize as a holding thread for wire thread inserts of the dimension UNC No. 10 x 24 in one operation.
The holding thread for UNC No. 10 x 24 thread inserts is also called STI thread (screw thread insert) or STI thread (in English Screw Thread Insert) and has an oversize so that the normal starting thread UNC No. 10 x 24 is restored after the thread insert is installed.

Our machine taps are powerful and reliable taps for efficient machining of threads in one operation on the machine. Machine taps are used primarily in industrial manufacturing. They are suitable for CNC machines, thread cutting machines, cordless drills and pneumatic thread cutting machines, among others. As they are characterised by high efficiency and low production costs, they are often used in series production. The thread is cut by machine in one operation.

This BaerCoil® tap can be used for through holes, as the long gate, the straight groove shape and the spiral point ensure that the chips are transported forward out of the hole

Cutting speed vc [m/min] = (Outer diameter * π * speed) / 1000

Rotation speed n [1/min] = (Cutting speed in m/min * 1000) / (Outer diameter * π)

Feedrate programming [mm/min] = speed * pitch

Please note that the above cutting speeds are indicative and must be adjusted depending on lubrication and actuation.
