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.
General use

1 Drill a hole 6 mm deep with the drill center
AL HD 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.
For medium up to For low up to medium If this occurs, use finger contact to verify if any
high feed rates feed rates core remains
