lubricants.
DRILLING WOOD OR PLASTIC
If backing block is not used, ease up on the
pressure just before the bit breaks through the
wood to avoid splintering. Complete the hole from
the opposite side immediately after the point
breaks through. If bit binds, reverse the drilling
operation to help remove the bit from the work.
DRILLING METAL
Make a center punch in the material for easier
starting. Use enough pressure to keep the bit
cutting. If the bit is allowed to merely spin in the
hole, it will become dull within a short time. When

drilling a larger hole, it is faster and easier on
your power pack to first make a smaller hole and
enlarge it to the required size. Lubricate the tip of
the bit occasionally with CUTTING OIL for easier
metal drilling. If bit binds, reverse the drilling to
help remove the bit from the work.
DRILLING MASONRY
Use carbide-tipped masonry bit for cinder block,
mortar, common brick, soft stone and other
materials. The amount of pressure to be used is
dependent upon the type of material being
drilled. Soft materials require less pressure
while the hard materials need more pressure to
prevent the drill bit from spinning.
