8. drilling
a. Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
b . Install the correct bit.
c . Verify that the direction-of-rotation selector (D) is at
the correct setting (forward).
d . Hold the drill firmly and place the bit at the point to be
drilled .
e . Press the trigger switch (E) to start the drill.
f. Move the drill bit into the workpiece, applying only
enough pressure to keep the bit cutting. Do not force
the drill or apply side pressure to elongate a hole.
Allow the tool to do the work.
g. When drilling hard, smooth surfaces, use a center
punch to mark the desired location of the hole. This
will prevent the drill bit from slipping off-center as the
hole is started.
h. When drilling metals, use light oil on the drill bit to
keep it from overheating. The oil will prolong the life
of the bit and increase the drilling action.
i . If the bit jams in the workpiece or if the drill stalls,
stop the tool immediately. Reverse the direction of
rotation and gently squeeze the trigger switch to
remove the bit from the workpiece. Investigate and
correct the cause of jamming before you resume
work.

9. drilling in Wood
For maximum performance, use high-speed steel or brad-point bits for wood drilling.
a. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
b . Increase the speed as the drill bit enters the material.
c . When drilling holes all the way through the workpiece, place a block of wood behind the
workpiece to prevent ragged or splintered edges on the back side of the hole.
