PS Wood Machines' Timber Wolf band saw blades run cooler, last longer and track true. Our 1/2” 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 1/2” x 4 tpi blades are generally used for straight-line cutting in 2-1/2”-6” hardwoods and 1-1/2”-4” softwoods. This is an excellent resaw blade if you want a little nicer finish than the 3 tpi but material height is limited to 6”. They can also make a 2-1/2” radius (5” diameter) cut
