Optimum Blade Pitch ( T.P.I. ) for Material Width ( Inches )
DETERMINE OPTIMUM BLADE PITCH -
TEETH PER INCH (T.P.I.)
Selecting a blade with proper tooth pitch is important in order to achieve optimal cutting rates and
good blade life.
For cutting narrow or thin wall structural materials a fine, blade with many teeth per inch (T.P.I.) is
recommended. For wide materials a blade with a coarse pitch should be used. See the sketch below for
the blade pitch changes fordiffering effective material widths.
It is impractical to change the blade to the proper pitch every time a different width of material is
cut and it is not necessary, but remember that the optimum blade will cut most efficiently. Too fine a
blade must be fed slower on wide material because the small gullets between the teeth will get packed
with chips before they get across and out of the cut. Too coarse a blade must be fed slower because it
has fewer teeth cutting and there is a limit to the depth of a cut taken by each tooth.
