PS Wood Machines' Timber Wolf band saw blades run cooler, last longer and track true. Our 3/8” x 4 tpi x .025 blades are made of Swedish Silicon Steel. The teeth are induction hardened, milled for true tracking and produce a thin kerf . These blades run under a little lower tension which is better for your band saw. Our welds are warranted. The 3/8” x 4 tpi blades are used for gradual curves and straight-line cutting in 2-1/2”-6” hardwoods and 1-1/2”-4” softwoods. They can make a 1-1/4” radius cut
