■Handling Procedure
-
Screw the shank into the core drill body.
*When removing the core body and the shank, place the body facing upward while inserted into the main unit and strike a few times to loosen the round screw. -
Insert and set the center pin while aligning it with hole on the tip end of the shank. Attach a guide plate to the set center pin.
-
Attach to the hammer drill as in the case with the conventional hexagonal shank drill and bull point.
-
Only the center pin is required for positioning. Pull out the center pin once the work material is drilled to a depth of approximately 5 mm and the drill tip end stops turning, then continue drilling operation.
