Abstract:
1. A saw blade, comprising: a saw blade body; and a group of teeth disposed on the saw blade body, the group of teeth having a non-set tooth and a plurality of set teeth, each of the plurality of set teeth disposed in a respective set direction relative to a midplane of the saw blade body, at least two teeth of the plurality of set teeth disposed in opposing set directions relative to the midplane of the saw blade body the plurality of set teeth including a total of no more than six set teeth, the group of teeth having the non-set tooth and the plurality of set teeth defining a toothform pattern of teeth, the toothform pattern of teeth repeated consecutively as a recurring pattern along an entire length of the saw blade body such that no intervening teeth and no intervening toothform patterns of teeth are disposed between each consecutively recurring toothform pattern of teeth, each tooth of the group of teeth disposed on the saw blade body at a relative pitch, the pitch defined as a distance between a tooth point of a respective tooth of the group of teeth and a tooth point of a preceding tooth of the group of teeth, the preceding tooth disposed proximate to a front end portion of the respective tooth, the pitch between the non-set tooth and a preceding set tooth of the group of teeth being the smallest pitch of the toothform pattern of teeth, such that the pitch between the non-set tooth and the preceding set tooth is less than the pitch between each set tooth of the plurality of set teeth and a corresponding preceding tooth of the group of teeth; wherein the plurality of set teeth comprises: a first set tooth disposed in a first set direction relative to the midplane of the saw blade body and a second set tooth disposed in the first set direction relative to the midplane of the saw blade body, the first set tooth and the second set tooth disposed in the first set direction being disposed on the saw blade body on opposing sides of the non-set tooth such that the first set tooth disposed in the first set direction is proximate to a front end portion of the non-set tooth and such that the second set tooth disposed in the first set direction is proximate to a trailing end portion of the non-set tooth; a first set tooth disposed in a second set direction relative to the midplane of the saw blade body and a second set tooth disposed in the second set direction relative to the midplane of the saw blade body, the second set direction opposing the first set direction, the first set tooth and the second set tooth disposed in the second set direction being disposed on the saw blade body on opposing sides of the non-set tooth such that the first set tooth disposed in the second set direction is proximate to a front end portion of the non-set tooth and such that the second set tooth disposed in the second set direction is proximate to a trailing end portion of the non-set tooth; a distance between the tooth point of the first set tooth disposed in the first set direction and the tooth point of the second set tooth disposed in the first set direction being substantially equal to a distance between the tooth point of the first set tooth disposed in the second set direction and the tooth point of the second set tooth disposed in the second set direction.
