WARNING
Drill Bits
Always inspect drill bits for excessive wear. Use only bits that are sharp and in good condition.
Twist Bits:
Available with straight and reduced shanks for wood and light-duty metal drilling.
High-speed bits cut faster and last longer on hard materials.
Carbide-Tipped Bits:
hard nonmetal materials. Use continuous, heavy feed pressure when using carbide-tipped
bits.

WARNING
with side shields during power tool
operation or when blowing dust . If
operation is dusty, also wear a dust mask .
a. Check that the direction-of-rotation selector
is at the correct setting (forward or reverse).
b. Secure the material to be drilled in a vise or
with clamps to keep it from turning as the
drill bit rotates.
c. Hold the drill firmly, and place the bit at the
point to be drilled.
d. Depress the variable-speed trigger switch to
start the drill.
e. Move the drill bit into the workpiece, applying only enough pressure to keep the bit "biting".
Do not force the drill or apply side pressure to elongate a hole. Let the tool do the work.
f. 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.
g. 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.
Use protective gloves when removing the bit from the tool, or first
allow the bit to cool down . The bit may be hot after prolonged use .
Used for drilling stone, concrete, plaster, cement, and other unusually
