Selecting Bits
When selecting a bit, use the right type for
your job. For best performance, always
use sharp bits.
Drilling in Wood, Composition Materi-
als and Plastic
When drilling in wood, composition materi-
als and plastic, start the drill slowly, gradu-
ally increasing speed as you drill. When
using twist drill bits, pull the bit out of the
hole frequently to clear chips from the bit
flutes. Use low speeds for plastics with a
low melting 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 re-
quire more pressure. A smooth, even flow
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 mate-
rial to prevent binding and distortion on
breakthrough.
Driving Screws
When driving screws, use the proper
screwdriver bit for your job. After drilling
pilot and shank holes, start the screw
slowly and increase the speed as driving
progresses. Set the screw by slowing to
a stop. Do not run screws down at exces-
sive speeds. To remove screws, reverse
the motor.
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
misaligned or when they are breaking
through a hole. Wood boring bits can also
bind if they run into nails or knots. Be pre-
pared for bit binding situations.

WARNING!
High rotational force. To reduce the
risk of injury, always hold or brace
secrely. Always use side handle on
tools rated 1200 RPM or less.
