Blade Information
the Model g0503 is a specialized machine that
requires specialized blades. grizzly industrial
has selected a series of blades for optimum per-
formance on this machine. the only variables
when selecting a blade are the type of cutting
tooth and the number of teeth-per-inch (tooth
pitch).
Blade Tooth Type
Carbon Steel—the less expensive carbon steel
blades are adequate for most cutting applica-
tions; however, they dull quickly and for economi-
cal reasons they are usually replaced rather than
resharpened.
Carbide Tipped—the more expensive carbide-
tipped blades are designed for continuous use
in production shop situations. they hold an
edge longer than carbon steel and they can be
resharpened many times before needing to be
replaced.
Tooth pitch
tooth pitch refers to the number of teeth-per-
inch. the more teeth-per-inch, the smoother the
resulting cut, but the feed rate must be relatively
slow. the less teeth-per-inch, the rougher the
resulting cut, but the feed rate can be set faster.
some trial and error may be necessary to find
the right combination of cut quality, tooth pitch
and feed rate.
Blade Length
the required blade length for the Model g0503
is 168".
Blade Width
the required blade width for the Model g0503
is 1".

Blade care
the resaw blade is a precision ground piece of
steel, subject to tremendous strain. increase the
life and performance of your blade by using the
correct feed rate and tension.
a clean blade will perform much better than a
dirty blade. a dirty blade passes through the cut-
ting material with much more resistance than a
clean blade. this extra resistance will also cause
unnecessary heat. Maintain your blades with a
cleaner like oxisolv

a cool blade will last longer than a blade that is
overheated. the best way to keep the blade cool
is with a coolant dispenser like the grizzly model
h4959 shown on page 33.
Blade Breakage
Blade breakage is unavoidable in some cases,
since it is the natural result of the peculiar stress-
es placed on the blade. Blade breakage may
also be due to avoidable circumstances, which
is most often the result of poor care or judge-
ment on the part of the operator when mounting
the blade, tensioning, or adjusting the support
guides.
The most common causes of blade breakage
are:
•
incorrect blade tension.
•
Feeding the workpiece too fast.
•
dull teeth or insufficient set.
•
not releasing blade tension after use.
•
Faulty adjustment of the blade guides.
•
using a blade with an improperly finished
braze or weld.
•
running the bandsaw excessively when not
resawing.
