housing, thread the circle cutting guide onto
the threaded portion of your Rotary Tool
clockwise until tight. Do not hold the
attachment by the metal rail during
installation. Do not overtighten (Fig. H4).
Step Five: Set depth guide to required
cutting depth
As shown (Fig. H5), loosen depth guide knob
7 and adjust the height of the depth guide 8
so that the bit 6 extends at least 1/8" more
than the material to be cut. Tighten depth
guide knob so depth guide is secure.
Step Six: Set the pivot foot knob to
diameter of hole to be cut
Loosen the pivot foot knob 1 and slide it to the
required diameter of hole to be cut. Line up the
knob with the diameter size of the circle you
wish to cut (Fig. H6a). For English (IN), use the
measurements on the top of the metal rule. For
Metric (CM) use the sides of the metal rule.
For holes 3/4"-9" (2cm-22cm), use the pivot
foot 2 as shown (Fig. H6a).
For holes 4"-12" (10cm-30cm), use the pivot
foot 2 as shown in drawing (Fig. H6b).
To change position of pivot foot, unscrew pivot
foot knob and remove pivot foot. Turn pivot
foot 180 degrees to alternate position and
tighten knob.
Step Seven: Drill a pilot hole for center of
circle and for cutting bit.
Drill a 1/8" pilot hole for center of circle (pivot
point) 9 and a pilot hole for cutting bit (outer
diameter) 10. When finished drilling each hole,
turn off the tool and remove it from the material
(Fig. H7).
Step Eight: Starting the circle cut
Note: the center point on the Circle Cutter pivot
foot is at the center of the circle you are about
to cut.
Place the tip of the center point in the opening
of the pilot hole and the bit in the opening of
the outer diameter pilot hole. Turn on the tool
and set to the desired speed. With one hand
on the tool, grasp the knob with the other
hand.
Step Nine: Cut out the circle
Start cutting in a clockwise direction using
consistent moderate pressure (Fig. H8). If you
need to reposition your hands, turn off the tool
first before changing hand positions.
