Inclined drilling
At the beginning, drill very slowly, since the drill bit does only starts cutting with a
fraction of the cut surface in the material. If you drill too fast or with too much
pressure, the drill bit could get jammed.
In order to reach the max. drilling depth, you probably have to use an extension for
the drill bit!
Demounting the Core Drill Unit
Move the machine holder with the core drill upwards until it locks in the final
top position.
Remove the drill bit.
Loosen the fastening nut (F) (see page 12)
While doing so, hold the drill rig firmly!
Remove the drill rig.
Unscrew the quick action clamping screw (D) (see page 12).
Drilling
BST 300: Furthermore, loosen the locking lever on
the bracing.
The scale on the toothed column makes adjusting
the drilling angle easier.
Remove the bolt, which holds the
column at a 90° angle, from the
foot plate.
Loosen both Allen screws M10 with
the enclosed wrench SW 8.
Position the column in the
appropriate angle and tighten both
screws again.
After drilling put the column back in
the 90° position and lock it with the
screw.
