Socket holder drilling

Do not drill the holes in the socket holder while the holder is installed in the selector.

The sensor elements are located in the bottom of the selector. For accurate detection it is important that the socket holder is directly above the sensor. Two options are available for drilling:

  • One single socket or bit in the center of the holder. This is shown by the center hole in the figure.

  • Two sockets or bits placed side by side in the holder. This is shown by the two outer holes in the figure.
