OPERATION
BIT REMOVAL
• Unplug the drill.
• Rotate the keyless chuck
counterclockwise while holding the chuck
grip to unlock the bit.
• Remove the bit
WARNING: In certain situations, the bit
may bind and the drill will kickback in the
opposite direction. This sudden reaction
could lead to loss of control and possible
serious injury. Always be prepared for the
possibility of kickback, especially when
breaking through material to complete
a hole.
DRILLING METAL
Use an even pressure, hard enough to
keep the drill biting, but not so hard that
the bit spins in the hole. Spinning the bit
will dull it quickly. Soft metals like copper,
cast iron, brass or aluminum will take less
pressure than harder materials like steel.
When drilling harder metals, use lubricating
oil on the tip of the bit.
DRILLING MASONRY
NOTICE: Always use carbide tip bits for
drilling masonry.
Use an even pressure, hard enough to
keep the drill biting, but not so hard that
the bit spins in the hole. Spinning the bit
will dull it quickly. Bricks and similar soft
materials will take less pressure than a
hard material like concrete.
DRILLING WOOD
WARNING: Always clamp the work
piece to a steady base. Never hold in
your hand or across your legs.
Apply pressure in line with the bit. Applying
pressure at an angle could cause the bit
to bind or break. Thin materials that may
splinter should be drilled with another piece
of wood placed underneath. Twist bits can
be used for wood drilling but will overheat
if the flutes are not cleared of wood chips
periodically. To prevent splintering when
finishing holes, stop drilling just before the
hole breaks through and complete the hole
from the other side.
