7. A band saw blade comprising:
a planar blade backer having parallel right and left sides opposite each other; and
a plurality of consecutive sets of teeth disposed on a top edge of the blade backer, where each of the plurality of consecutive sets of teeth includes:
a first straight tooth;
a second set tooth, following the first straight tooth and being one of left-set or right-set;
a third set tooth, following the second set tooth and being the other of left-set or right set;
a fourth set tooth, following the third set tooth and being set in the same direction as the second set tooth; and
a fifth set tooth, following the fourth set tooth and being set in the same direction as the third set tooth;
where the plurality of consecutive sets of teeth includes a first set of teeth and a second set of teeth, the second set of teeth being consecutive with the first set of teeth, and the plurality of consecutive sets of teeth having a first tip-to-tip distance between the fourth set tooth of the first set of teeth and the second set tooth of the second set of teeth and a second tip-to-tip distance between the second set tooth and the fourth set tooth in the first set of teeth and where the first tip-to-tip distance between the fourth set tooth of the first set of teeth and the second set tooth of the second set of teeth is between 0.70 times and 1.30 times the second tip-to-tip distance between the second set tooth and the fourth set tooth in the first set of teeth, and the plurality of consecutive sets of teeth having a third tip-to-tip distance between the fifth set tooth of the first set of teeth and the third set tooth of the second set of teeth and a fourth tip-to-tip distance between the third set tooth and the fifth set tooth in the first set of teeth and where the third tip-to-tip distance between the fifth set tooth of the first set of teeth and the third set tooth of the second set of teeth is between 1.00 times and 1.25 times the fourth tip-to-tip distance between the third set tooth and the fifth set tooth in the first set of teeth; and
where each of the sets of the plurality of consecutive sets of teeth further includes:
a first gullet formed in the top edge of the blade backer and disposed between the first straight tooth and the second set tooth, the first gullet having a maximum first gullet depth and a maximum first gullet length;
a second gullet formed in the top edge of the blade backer and disposed between the second set tooth and the third set tooth, the second gullet having a maximum second gullet depth and a maximum second gullet length; and
a third gullet formed in the top edge of the blade backer and disposed between the third set tooth and the fourth set tooth, the third gullet having a maximum third gullet depth and a maximum third gullet length;
where the maximum third gullet depth is greater than the maximum first gullet depth and the maximum second gullet depth; and
where the maximum second gullet depth is greater than the maximum first gullet depth; and
where the maximum third gullet length is greater than the maximum first gullet length and the maximum second gullet length.
