Plunge Cutting (Fig . 15)
Plunge cutting is useful and time-saving when
making rough openings in softer materials: it's
not necessary to drill a hole for an inside or
pocket cut. Do not try to plunge cut into hard
materials, such as steel.
1. Draw lines for the opening,
2. Hold the saw firmly and tilt it forward so that
the toe of the saw foot rests on the work, but
with the blade well clear of the work.
3. Start the motor, and then very gradually
lower the blade.
4. When the blade touches, continue pressing
down on the toe of the saw foot while slowly pivoting the saw like a hinge until the blade
cuts through and the foot rests flat on the work.
5. Then saw ahead on the line of cut line.
NOTICE: We do not recommend plunge cutting with a scroll blade.
To make sharp corners, cut up to the corner, then back up slightly before rounding the corner.
After the opening is complete, go back to each corner and cut it from the opposite direction to
square it off.
