Adjusting the Premium Face Clamp
Turn the adjustment screw of the Premium Face
Clamp in the counter-clockwise direction for
thicker materials and clockwise direction for
thinner materials. Clamping pressure is also
adjusted using the same adjustment screw; after
sizing the clamp opening for the thickness of
material, a half-turn of the adjustment screw
in the clockwise direction will provide sufficient
clamping pressure to hold the jig in place during
drilling. To increase clamping pressure turn the
adjustment screw clockwise; likewise to decrease
clamping pressure turn the adjustment screw
counter-clockwise.
Portable Base Wood Chip Extraction
There are openings in the rear surface of the
Portable Base that align with the chip extraction
holes in the Drill Guide Block to allow a free path
for wood chips to exit the Drill Guide Block. By
allowing chips to escape less friction will occur
with the rotating drill bit thereby easing the drilling
stroke and extending drill bit life.
Temporary Mounting Portable Base
The bottom of the Portable Base contains three
holes that allow it to be temporarily attached to
a workbench for drilling pocket holes in a vertical
orientation, similar to the Benchtop Base.
The function of the Portable Base in this setting
is virtually the same. The Drill Guide Block is set
for the thickness of material to be drilled and the
Depth Collar is set to the same corresponding
thickness. Although the Premium Face Clamp is
recommended for this operation, another type of
C-clamp may be used.
