Under regular conditions it is possible to adjust the center line of the drill (X-axis of the machine) in order to change hole diameter size.

CORE 1 Drill a hole 6 mm deep with the drill center line aligned with the spindle center line. 2 Check the existing core. If there is no core, check the alignment of the Y-axis of the drill and spindle. Correct by checking the adapter or adjusting the Y-axis. 3 Check that the hole diameter equals the drill diameter +0.0- +0.2 mm. If not, adjust the X-axis. 4 Note: In some operations, part of the core may break. If this occurs, use finger contact to verify if any core remains

Warning: As the drill goes all the way through a workpiece, it ejects a disc. For worker safety, guards should be used..
