Operating Instructions
VARIABLE SPEED CONTROLLED
Your tool is equipped with a variable speed trigger
switch. The tool can be turned "ON" or "OFF" by
squeezing or releasing the trigger (Fig. 1).
The speed can be adjusted from the minimum to
maximum nameplate RPM by the pressure you
apply to the trigger.
Apply more pressure to increase the speed and
release pressure to decrease speed.

Your drilling depth can be pre-set and/or
repeated by using the depth gauge.
Setting depth: After the auxiliary handle is
installed, make sure the accessory has been
fully inserted into the tool holder before setting
t
he depth gauge (Fig. 5).
To adjust depth, push down on the depth
gauge release lever, slide the depth gauge to
desired depth and release pressure on lever to
lock the depth gauge in place (Fig. 5).
CHUCK KEY & STORAGE AREA
Your tool is equipped with a chuck key that is
conveniently located on the cord protector
where it is always handy and unlikely to get lost
or misplaced (Fig. 1).
For small bits, open jaws enough to insert the
bit up to the flutes. For large bits, insert the bit
as far as it will go. Center the bit as you close
the jaws by hand. This positions the bit
properly, giving maximum contact between the
chuck jaws and the bit shank.
To tighten chuck, insert key into each of the
three key holes in succession and tighten

You will extend the life of your bits and do
neater work if you always put the bit in contact
with the work before pulling the trigger. During
the operation, hold the tool firmly and exert
light, steady pressure. Too much pressure at
low speed will stall the tool. Too little pressure
will keep the bit from cutting and cause excess
friction by sliding over the surface. This can be
damaging to both tool and bit.
DRILLING WITH VARIABLE SPEED
The trigger controlled variable speed feature
will eliminate the need for center punches in
hard materials. The variable speed trigger
Operating Tips
allows you to slowly increase RPM. By using a
slow starting speed, you are able to keep the bit
from “wandering”. You can increase the speed
as the bit “bites” into the work by squeezing the
trigger.
Variable speed drills will double as a power
screwdriver by using a screwdriver bit in the drill
mode. The technique is to start slowly,
increasing the speed as the screw runs down.
Set the screw snugly by slowing to a stop. Prior
to driving screws, pilot and clearance holes
should be drilled.

Second, unclamp the pieces and drill the

Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Then, simply apply even pressure
when driving the screw. The screw shank

screw head to pull the pieces tightly together.

Always inspect drill bits for excessive wear. Use
DRILL BITS
only bits that are sharp and in good condition.
TWIST BITS: Available with straight and
reduced shanks for wood and light duty metal
drilling. High speed bits cut faster and last
longer on hard materials.
CARBIDE TIPPED BITS: Used for drilling
stone, concrete, plaster, cement and other
unusually hard nonmetals. Use continuous
heavy feed pressure when employing carbide
tip bits.
DRILLING WOOD
Be certain workpiece is clamped or anchored
firmly. Always apply pressure in a straight line
with the drill bit. Maintain enough pressure to
keep the drill “biting”.
When drilling holes in wood, twist bits can be
used. Twist bits may overheat unless pulled out
frequently to clear chips from flutes.
Use a “back-up” block of wood for work that is
likely to splinter, such as thin materials.
You will drill a cleaner hole if you ease up on
the pressure just before the bit breaks through
the wood. Then complete the hole from the
back side.
There are two rules for drilling hard materials.
DRILLING METAL
First, the harder the material, the greater the
pressure you need to apply to the tool. Second,
the harder the material, the slower the speed.
Here are a couple of tips for drilling in metal.
Lubricate the tip of the bit occasionally with
cutting oil except when drilling soft metals such
as aluminum, copper or cast iron. If the hole to
be drilled is fairly large, drill a smaller hole first,
then enlarge to the required size, it’s often
faster in the long run. Maintain enough
pressure to assure that the bit does not just
spin in the hole. This will dull the bit and greatly
shorten its life.
DRILLING MASONRY
Soft materials such as brick are relatively easy
to drill. Concrete however, will require much
more pressure to keep the bit from spinning. Be
sure to use carbide tip bits for all masonry work.
WARNING
!
Before using an accessory,
be certain that its maximum
safe operating speed is not exceeded by the
nameplate speed of the tool. Do not exceed
the recommended wheel diameter.

Fine sanding and polishing require “touch”.
S
When using polishing bonnets, alway be sure
the excess string that secures the bonnet is
tucked well within the bonnet during operation.
Variable speed control must be used with
caution for driving nuts and bolts with socket
set attachments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.
Work with brushes requires high speeds.
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come in
contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping

action; and if this is continued, the life of the
brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible is
in full contact with the work. Applying the
side or edge of the brush to the work will
result in wire breakage and shortened brush
life.
