Product information

BAER HSSE-TiCN Machine Tap Form C for Cast Iron - M 3.5 x 0.6 - DIN 371

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 a reinforced shank according to DIN 371. This means that the shank diameter is larger than the thread itself. This makes the screw tap run more stably. However, it limits the thread length that can be cut with it. It can be used for through holes and for blind holes, because the short chamfer and the straight flutes shape ensure that the chip stays in the flutes and is not carried 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. 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.
The TiCN coating is particularly suitable for use with high-strength steels, abrasive materials and also interrupted cuts, as it is less sensitive to impact loads. TiN is often insufficient and increased demands are made on hardness and toughness, in which case TiCN is used. However, because of the lower heat resistance, a stronger cooling of the TiCN-coated tools is important.

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.
