Drilling

WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood
"back-up" block to prevent damage to the material.
1. Use sharp drill bits only. For WOOD, use twist drill bits,
spade bits, power auger bits, or hole saws. For METAL,
use steel twist drill bits or hole saws.
2. Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push
hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting
action of the drill.
4. IF DRILL STALLS, it is usually because it is being
overloaded or improperly used. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and
determine cause of stalling. DO NOT CLICK TRIGGER ON
AND OFF IN AN ATTEMPT TO START A STALLED DRILL
— THIS CAN DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.
6. Keep the motor running when pulling the bit back out
of a drilled hole. This will help prevent jamming.
Drilling in Metal
Start drilling with slow speed and increase to full power
while applying firm pressure on the tool. A smooth even
flow of metal chips indicates the proper drilling rate. Use a
cutting lubricant when drilling metals. The exceptions are
cast iron and brass which should be drilled dry.
nOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel
can be made easier if a pilot hole [5/32" (4 mm) to 3/16" (5
mm)] is drilled first.

Drilling in Wood
Start drilling with slow speed and increase to full power
while applying firm pressure on the tool. Holes in wood can
be made with the same twist drills used for metal. These
bits may overheat unless pulled out frequently to clear chips
from the flutes. Work that is apt to splinter should be backed
up with a block of wood.
