Product information

BAER HSSE Machine Tap Form B - M 22 x 2.5 - LEFT - DIN 376

Our machine taps are powerful and reliable taps for efficient machining in one step with the machine. Machine taps are used especially in industrial manufacturing. They can be used in CNC machines, thread cutting machines, cordless drills and pneumatic tapping arms, 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. Thus, although the BAER machine tap can basically be compared with short machine taps, it is designed for use with the machine.
The left- screw tap is operated counterclockwise, just as a screw with left-hand thread is tightened counterclockwise.
The screw tap has an overflow shank according to DIN 376. This means that the shank has a smaller diameter than the thread. This means that the screw tap can also be used in deeper holes and longer thread lengths. This means that the spiral point (spiral entry) can also be used in deeper holes and longer thread lengths, as the long chamfer, the straight flutes and the ensure that the chip is transported forwards out of the hole.
Every material has its own individual chip behaviour. Therefore, screw taps must have the correct rake angle and - for even better results - a specially treated surface. This is the only way to achieve a good chip transport and to produce a thread that is true to gauge.
The high quality of the cobalt-alloyed HSSE steel we use ensures that our tools are extremely durable and robust. Due to special hardening processes and repeated tempering the hardness structure is very homogeneous, which forms the ideal basis for a genuine BAER screw taps. This increases the toughness and stability of the screw taps, allowing them to remain in use for longer.

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.
