WARNING
To reduce the risk of explosion,
electric shock and property
damage, always check the work
area for hidden pipes and wires
before drilling.
Selecting Bits
When selecting a bit, use the right type for
your job. For best performance, always use
sharp bits.
Drilling
1. Before drilling, be sure the workpiece is
clamped securely. Use backing material
to prevent damage to the workpiece
during breakthrough.
2. When starting a hole, place the drill
bit on the work surface and apply fi rm
pressure. Begin drilling at a slow speed,
gradually increasing the speed as you
drill.
3. Always apply pressure in line with the bit.
Use enough pressure to keep the drill
biting, but do not push hard enough to
stall the motor.
4. Reduce pressure and ease the bit
through the last part of the hole. While
the tool is still running, pull the bit out of
the hole to prevent jamming.

Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, start the drill slowly, gradually
increasing speed as you drill. When using
twist drill bits, pull the bit out of the hole
frequently to clear chips from the bit fl utes.
Use low speeds for plastics with a low melt-
ing point.
Drilling in Masonry
When drilling in masonry, use high speed
carbide-tipped bits. Drilling soft masonry
materials such as cinder block requires
little pressure. Hard materials like concrete
require more pressure. A smooth, even fl ow
of dust indicates the proper drilling rate. Do
not let the bit spin in the hole without cutting.
Do not use water to settle dust or to cool bit.
Both actions will damage the carbide.
Drilling in Metal
When drilling in metal, use high speed steel
twist drills or hole saws. Use slow speeds
for hard metals and high speeds for softer
metals. Lubricate drill bits with cutting oil
when drilling in iron or steel. Use a coolant
when drilling in nonferrous metals such as
copper, brass or aluminum. Back the ma-
terial to prevent binding and distortion on
breakthrough.

Driving Screws
When driving screws, use the proper screw-
driver bit for your job. After drilling pilot and
Steel
shank holes, start the screw slowly and
increase the speed as driving progresses.
Hole
Set the screw by slowing to a stop. Do not

Stalling
NR
If the tool seems as if it is about to stall, main-
tain a fi rm grip and reduce pressure slightly
1-5/8"
to allow the bit to regain speed. If the tool
2"
does stall, release the trigger immediately.
2"
Reverse the motor, remove the bit from the
work and start again. Do not pull the trigger
2"
on and off in an attempt to start a stalled drill.
This can damage the drill.
High rotational force. To reduce the
risk of injury, always hold or brace
securely. Always use side handle on
tools rated 1200 rpm or less.
Bit Binding
A high rotational force occurs when a bit
binds. If the bit binds, the tool will be forced in
the opposite direction of the bit rotation (See
Fig. 12-14). Bits may bind if they are mis-
aligned or when they are breaking through a
hole. Wood boring bits can also bind if they
run into nails or knots. Be prepared for bit
binding situations.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely
to bind when drilling.
• Use the proper bit for the job. There
are bits that are designed for specifi c
purposes.
• Use caution when drilling pitchy, knotty,
wet or warped material or when drilling
in material that may contain nails.
