Porter-Cable PCXB340SS - Blade Selection

NOTE:
● When using blades, sometimes speeds
must change to compensate for smaller
curves, radii or smaller diameters. Thinner
blades will have more possibilities for
blade deection when cutting angles
which are not perpendicular to the
table. Read RECOMMENDATION FOR
CUTTING for more suggestions.
● The blade must be installed with the
teeth pointing downward, to prevent the
workpiece from being pulled upward by
the saw blade action.
BLADE SELECTION (FIG. N)
To avoid injury from accidental starting,
always turn the switch OFF and unplug the
scroll saw before moving, replacing the
blade or making adjustments.
This scroll saw accepts 5 in. (127 mm) length
blades with a wide variety of blade thickness
and widths. The type of material and cutting
operations (size of radius or curve) will
determine the number of teeth per inch. As a
rule, always select the narrowest blades for
intricate curve cutting and the widest blades
for straight and large curve cutting operations.
The following table represents suggestions
for various materials. When purchasing
blades, refer to the back of the package for
the best use of blades and speeds on various
materials.
Use this table as an example, but practice
and your own personal preference will
determine the best selection method.
