Operating Instructions
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed trigger
switch. The tool can be turned "ON" or "OFF" by
squeezing or releasing the trigger. 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
(Fig. 1).
"LOCK-ON" BUTTON
The "Lock-ON" button, located in the handle of
your tool allows for continuous operation at
maximum RPM without holding the trigger (Fig.
1).
TO LOCK TRIGGER "ON": squeeze trigger,
depress button and release trigger.
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).
INSERTING BIT
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

Operating Tips
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
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.
DRILL BITS
Always inspect drill bits for excessive wear.
Use 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.
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.
Use carbide-tipped masonry bit for cinder
block, mortar, common brick, soft stone and
other materials. The amount of pressure to be
used is dependent upon the type of material
being drilled. Soft materials require less
pressure while the hard materials need more
pressure to prevent the drill bit from spinning.
Drill only action: For drilling in woods,
metals, plastics or other non concrete
materials.
Drill with hammer action: For drilling
in
masonry, asphalt, tile or other
similar hard materials.
