Swedish silicon steel Run cooler and last longer Teeth are milled Run under low tension and produce a thin kerf PS Wood Machines’ Timber Wolf band saw blades run cooler, last longer and track true. Our ¼” x 6 tpi x .025 blades are made of Swedish Silicon Steel. The teeth are induction hardened, milled for true tracking, produce a thin kerf and make remarkably tight turns. These blades run under a little lower tension which is better for your band saw. Our welds are warranted. The ¼” x 6 tpi blades are used for cutting ¾”- 2-1/2” hardwoods and ½”-1-1/2” softwoods. They can make a 5/8” radius cut. These blades are considered our most universal, multi-purpose blades
