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.
Use carbide-tipped masonry bit for cinder
block, mortar, common brick, concrete, 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
This procedure shown in (Fig. 5) will enable
you to fasten materials together with your
Cordless Drill/Screwdriver without stripping,
splitting or separating the material.
First, clamp the pieces together and drill the
first hole 2/3 the diameter of the screw. If the
material is soft, drill only 2/3 the proper
length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the
second hole the same diameter as the screw
shank in the first or top piece of wood.
Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Then, simply apply even pressure
when driving the screw. The screw shank
clearance hole in the first piece allows the
screw head to pull the pieces tightly together.
The adjustable screw drill accessory will do
all of these operations quickly and easily.
Screw drills are available for screw sizes No.

It is not recommended to drill holes larger
than 3/8" diameter through soft steel thicker
than 1/8". Drilling through metal rapidly

from spinning.
It is not recommended to drill holes larger
than 3/8" diameter in masonry material. Doing
so rapidly drains energy from the battery
pack.
