      GARANT deep-hole drilling systems

      Perfectly matched for process-reliable drilling.


      GARANT deep-hole drills

      For trouble-free and process-reliable deep-hole drilling up to 50×D. The individual tools are perfectly matched in respect of geometries, the tolerances of the cutters and the point angles.

      Within the production process this system ensures a seamless switch from one tool to the other. The proven colour rings are an additional aid for the selection of the right tool.

      A system for highest precision


      Exact deep-hole drilling is a challenge. With the GARANT deep-hole drilling system these problems can be solved in a process-reliable way.

      1. NC spotting drill - The right start:
      Reliable even for difficult machining requirements – the GARANT deep-hole drilling system. Start by spot drilling (especially for horizontal machining) for exact location and alignment accuracy.

      2. The pilot drill will set the direction:
      The pilot drill will generate a bore 6×D – the ideal preparation for deep-hole drilling.
      Important: Following this, especially for horizontal machining, generate a countersink.

      3. The co-pilot drill will clear the way:
      Basically alreay a deep-hole drill, the co-pilot drill will generate a precise 20×D bore (necessary for deep-hole drill 40×D / 50×D).

      4. The final deep-hole drilling step:
      Precision right to the very end – the GARANT deep-hole drill guarantees a reliable and trouble-free completion of the total process (50xD).
