OPERATION
BAND SAW BLADES
MODEL 725 requires 44
7
/
8
" long blades that are .020" thick and
1
/
2
" wide.
Blades for stationary band saws are of different
thickness than above and WILL NOT fit the precision blade guides on
portable band saws. Therefore, they MUST NOT be used.
Refer to the blade selection chart in the Porter-Cable catalog (see
“ACCESSORIES” section in this manual) for types of blades available and
their recommended usages. This chart is provided as a guide only. Due to the
many materials that can be cut, operator’s experience will determine which
blade will have the longest life for any specific operation.
WHICH BLADE TO USE
In general, select a blade which will allow at least two teeth to be engaged in
the material thickness. The thinner or the harder the material, the finer the
blade teeth. The thicker or the softer the material, the coarser the blade teeth.
The hi-speed steel blades stay sharp longer than carbon steel blades.
