Drilling and tapping pneumatic maachine gun TRADEMAX ATH 12 1

Drilling machines and tapping machines are used to drill or thread holes in a surface. Drilling machines and tapping machines vary from the tiny bench machine used in the finest jeweler’s operation to the huge, heavy-duty machines that bore large holes in steel forgings at an astonishing rate. The most commonly used drilling machine is the vertical drilling machine known as a drill press. Proper selection of a drilling and tapping tool depends on the material to be tapered or drilled, the length of the thread to be formed, and the accuracy required. There are several types of tapping machines. Examples include a thread tapping machine and a pneumatic tapping machine. A thread tapping machine is used for tapping taper holes. A pneumatic tapping machine is a tapping machine that is driven by compressed air. Special drilling machines and tapping machines are used for wood, glass, and plastics for which standard machines cannot be used. Other drilling and tapping machines are commonly available.
