INSTRUCTIONS FOR CREATING CUT-OUTS IN DRYWALL
After assembling the bit into the tool as
described earlier, it will be necessary to review
the instructions provided below and make some
practice cut-outs with this tool before attempting
an actual job. The best method is to take some
scrap pieces and nail or screw them in place
over wall studs which have an electrical box or
other feature in place. A few such exercises will
give you the necessary practice to make clean,
professional cutouts around whatever is behind
the drywall you are installing.
Step 1: Be certain that the box or fixture is
firmly mounted and all wires or other
obstructions around the opening are pushed
back out of the way. The bit uses the outer
edge of the box or fixture as a guide, so it is
important that there is nothing in the way
which can prevent it from guiding completely
around the opening. For the purposes of this
instruction manual, the procedure discussed
will be to make a cut-out around a standard 2
1/8" x 3 3/4" electrical box.
Step 2: Slide switch to turn the tool on. While
holding the tool firmly with both hands,
plunge the bit through the mark you made.
Then guide the bit to the right until you feel
and hear the bit touch the inside edge of the
box (Fig. 9).

Step 3: Pull the bit out far enough to slip it
over the edge of the box so it is now against
the outside of the box (Fig. 10).
Step 4: While keeping the bit in contact with
the outside of the box move the tool counter
clockwise while applying light inward and
upward pressure until you feel and hear it
come to the corner. As you round the corner
apply light pressure left and downward (Fig. 10).

tool to make cut-outs
around any fixture or opening which has
live electrical wires, or on any wall which
may have live electrical wiring behind it, as
the bit could conduct current to the tool,
creating an electrocution hazard for the
operator. Shut off breakers or remove fuses to
disconnect the circuit. Always hold the tool by
its thermoplastic housing, and always wear
eye protection when operating this device.
Step 5: While moving slowly and continuously
along the top contour you will feel the bit come
to the next corner. Round the corner and
apply light down and inward pressure until the
bottom corner is reached (Fig. 10).
Step 6: Move the bit right and upward
maintaining light continuous pressure toward
the box (Fig. 10).
Step 7: Round the right bottom corner and
begin moving the bit upward while applying
light pressure left toward the box until you
meet initial upward cut. Push tool switch to off
(Fig. 10).

Step 8: The completed box, executed quickly,
neatly, and in a fraction of the time taken by
other methods.
NOTE: These step-by-step instructions are
generalized to acquaint you with the tool's
operation. After some practice, you may
develop a technique with which you are more
comfortable. However, you must always begin
the cut somewhat centrally, and MOVE THE
