BAER HSSE-TiN Machine Tap Form B - M 20 x 2.5 - 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 to short machine tap, it is designed for use with the machine.
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 that 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.
The TiN coating is particularly suitable for soft to hard steels, cast iron and many non-ferrous metals. As a proven universal coating, TiN offers a wide range of applications. TiN-Tools can be recoated up to five times without prior decoating.

Velocità di taglio vc [m/min] = (Diametro esterno * π * velocità) / 1000
Velocità di rotazione n [1/min] = (Velocità di taglio in m/min * 1000) / (Diametro esterno * π)
Programmazione della velocità di avanzamento [mm/min] = velocità * passo
Si prega di notare che le velocità di taglio sopra indicate sono indicative e devono essere regolate in base alla lubrificazione e all'azionamento.
