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.
10 Teeth per inch
14 Teeth per inch
18 Teeth per inch
24 Teeth per inch
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

blades. Use coarse pitch blades for thick wood
and fine pitch blades for thin work. It is
important to keep at least three teeth in the cut
(see "Typical Application".)
