G8994 Variable Speed Jig Saw -4 -
Always select the correct saw blade for the
material being cut. The resulting cut will be
cleaner and more accurate, and there will
be less stress on the machine. This Jig
Saw can be used to cut wood, metal or
plastics depending upon the type of blade
selected. The blades used must be of the
Bosch
® style mount. Grizzly offers a variety
of blade styles in the current catalog.
A few points to remember in making your
blade selection:
1. The overall blade length will affect
the thickness of material which
can be cut. Most jig saw blades
range in length from 3" to 5".
2. The width of the blade (measured
from the tip of one of the teeth to
the back edge) affects how tight of
a curve can be cut. A 3⁄16" wide
blade will cut a tighter circle than a
3⁄8" wide one.

3. The number of teeth per inch
(T.P.I.) affects the smoothness
and speed of the cut. A wood cut-
ting blade for general purpose will
usually have 6-10 T.P.I., a metal
cutting will have 12-20 T.P.I.
Another factor is the tooth style
and how the teeth are set (the
amount the tooth is bent away
from the plane of the blade). Most
blade manufacturer’s provide
guidelines on their packaging for
the types of materials and speeds
to use for a particular blade style.
Review their guidelines carefully
before choosing a blade for a par-
ticular project.

wood and metal cutting available from
