• Lubricate the tip of the bit occasionally
with cutting oil, except when drilling
soft metals such as aluminum, copper,
or cast iron.
• If the hole to be drilled is fairly large,
drill a smaller hole first, then enlarge to
the required size. It's often faster in the
long run.
• Maintain enough pressure to assure that
the bit does not just spin in the hole.
This will dull the bit and greatly shorten
its life.
Wire Brush (Wheels and Cups)
Wire brushes are intended to "clean" struc-
tural steel, castings, sheet metal, stone,
and concrete. They are used to remove rust,
scale, and paint.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work
surface, allowing the tool to operate at
high speed.
3. Continuously move the tool at a moder-
ate speed to avoid creating gouges in
the work surface.
4. Remove the tool from work surface
before turning tool off. Allow the tool to
stop rotating before laying it down.
Tip: The tips of the brush do the work. Oper-
ate wire brushes with the lightest pressure
so only the tips of the wire come in contact
with the work piece. If heavier pressures are
used, the wires will be overstressed, result-
ing in a wiping action and a shortened brush
life due to wire fatigue. Applying the side or
edge of the brush to the work piece will re-
sult in wire breakage and shortened brush
life.

CORRECT: Wire tips are doing the work.
INCORRECT: Excessive pressure can
cause wire breakage.
