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.
7. With variable speed drills there is no need to
center punch the point to be drilled. Use a
slow speed to start the hole and accelerate by
squeezing the trigger harder when the hole is
deep enough to drill without the bit skipping out.
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.
DRILLING IN MASONRY
When drilling in masonry, use carbide-tipped bits
rated for percussion drilling and be certain that the
bits are sharp. Use a constant and firm force on the
tool to drill most effectively. A smooth, even flow of
dust indicates the proper drilling rate.

other harsh chemicals for cleaning the
non-metallic parts of the tool. These
