Product information

BaerCoil HSSE Machine Tap UNF 10 x 32 STI (oversized for wire thread inserts) - PRO for blind 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 UNF No. 10 x 32.
The holding thread for UNF No. 10 x 32 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 UNF No. 10 x 32 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.

The machine tap can be used for blind holes, as the short gate and the swirl groove shape ensure that the chips are discharged to the rear

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.
