When drilling hard smooth surfaces use a center punch
to mark desired hole location. This will prevent the drill bit
from slipping off center as the hole is started. However,
the low speed feature allows starting holes without center
punching if desired. To accomplish this, simply operate
your drill at a low speed until the hole is started.
The material to be drilled should be secured in a vise or
with clamps to keep it from turning as the drill bit rotates.
Hold tool firmly and place the bit at the point to be drilled.
Depress the switch trigger to start tool.
Move the drill bit into the workpiece applying only enough
pressure to keep the bit cutting. Do not force or apply side
pressure to elongate a hole.
Be prepared for binding or bit
When these situations occur, driJl has
a tendency to grab and kick opposite to the direction
of rotation and could cause loss of control when
breaking through material. If not prepared, this loss of
control can result in possible serious injury.
When drilling metals, use a 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.
If the bit jams in workpiece or if the drill stalls, release
switch trigger immediately. Remove the bit from the work-
piece and determine the reason for iamming.
