▶ Blades And Blade Selection
The blade dimensions required for this
saw is: .020" thickness, 1/2" wide and
28-3/4" in length. The .020" thickness
reduces blade fatique and provide
maximum tooth life. To maximum
cutting life, use a blade with correct
pitch (teeth per inch) for the specific
cutting job.
Blade are available in several pitches. To
select the proper blade, three factors
should be considered: The size, shape,
and type of material to be cut.
The following suggestions are for
selecting the right blade for various
cutting operations. Keep in mind that
these are broad guide lines and that
blade requirement vary depending upon
specific size, shape and type of material
to be cut.

blades for thick wood and fine pitch

keep at least three teeth in the cut (see
"Typical Application".)
