BAER HSSG Combined Bit Tap M 4 x 0.7


BAER combined bit taps are designed for thread cutting with cordless drills and hand drilling machines with clockwise and anti-clockwise rotation. However, they are also suitable for thread cutting on stationary drilling machines. Their field of application is the machining of steel, non-ferrous metals and plastics (up to 600 N/mm² tensile strength). Only through holes up to a maximum thread depth of 1 x diameter can be produced. They are particularly useful for assembly work and small series. Make sure that the tool axis and hole axis are exactly aligned and use a suitable cutting oil. For the thread cutting with cordless screw drivers and hand drillig machines we recommend a maximum speed of 1200 rpm for the dimension M 4 x 0.7.
