 grasp running lines centrically. So that the workpiece is gripped centrally by the jaws regardless of diameter. the spindle 14 has two different threads for the two jaws. To insert the workpiece, the clamping device is pivoted, then turned back to the stop 24 and secured by the pin 22.
 EMI1.4
 Clamping device 23 lies the drill guide. It consists of two guide plates 8, between which the guide jaws 3, designed as profile rods, are inserted.

   Depending on the Fo m of the holes to be drilled, the drill 2 and its guide jaws 3 are obtained in a known manner
 EMI1.5
 Moving one of these jaws will inevitably move the others along with it, thereby enlarging or reducing the size of the hole in question, which serves as a guide for the drill.



  The screws 17 are used to move the jaws.
