Plunge Cutting

(Fig. 11)
Plunge cutting is useful and time-saving in mak-
ing rough openings in softer materials. It is not
necessary to drill a hole for an inside or pocket
cut. The longest blade to be used for plunge cut-
ting is 3-1/8" (80 mm). Footplate must be set
0° setting.
Draw lines for the opening, hold the saw firmly,
tilt it forward so that the toe of the saw foot
rests on the work, but with the blade well clear
of the work. Turn the tool on and run at top
speed, and then very gradually lower the blade
(Fig. 11).
When it touches, continue pressing down on the
toe of the saw foot slowly pivoting the saw like
a hinge until the blade cuts through and the foot
rests flat on the work. Then saw ahead on the
cutting line. We do not recommend plunge cut-
ting with a scroll blade. Do not try to plunge cut
into hard materials such as steel.
To make sharp corners, cut up to the corner,
then back up slightly before rounding the cor-
ner. After the opening is complete, go back to
each corner and cut it from the opposite direc-
tion to square it off.
