ABSTRACT:
A saw blade, such as a bandsaw blade, has a toothform pattern that includes a raker tooth and set teeth. The bandsaw blade teeth are configured such that a distance from a tooth point of the raker tooth to a tooth point of an immediately preceding set tooth is the smallest tooth spacing in the saw blade toothform pattern. With the use of a smaller spacing, the raker tooth removes the smallest chip thickness from a work piece relative to the chip thicknesses removed by the set teeth. This reduces the amount of load imposed on the raker tooth point. In one arrangement, in order to balance the forces on either side of the blade during operation, the saw blade is configured such that an accumulated pitch of the tooth points set to a first side of the blade are substantially equal to the accumulated pitch of the tooth points set to a second opposing side of the blade.
