BAER HSSG Machine Tap - Form C - UNS 3/4 x 24 - ISO 529
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 machine tap can be used for through holes and for blind holes, as the short chamfer-in and the straight flutes ensure that the chip remains in the flutes and is not transported away.
Every material shows individual chip behaviour. Therefore, screw taps must have the correct rake angle and - for even better results - a specially treated surface. Only in this way does a good chip transport take place and a thread containing gauges is produced.
The high quality of the ground HSS high-speed 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.

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.
