BaerCoil HSSE Machine Tap M 6 x 1.0 STI (oversized for wire thread inserts) - ECO for through holes
BaerCoil® machine taps are mainly used for thread repair or thread reinforcement in connection with wire thread inserts. With this BaerCoil® screw tap a finished thread with oversize can be cut in one operation as a holding thread for wire thread inserts of the dimension M 6 x 1.0.
The holding thread for M 6 x 1.0 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 initial thread M 6 x 1.0 is restored after installation of the thread insert.
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.
