Spyder Tools’ Skeleton jig saw blades are designed to produce clean, straight and cool cuts in hardwoods, softwoods and wood-based products. The rectangular channel section cut-outs dissipate frictional heat throughout the length of the blades so they stay cooler, resulting in less deflection and straighter cuts than traditional jig saw blades. Their rip-cut, gill-shaped teeth are made for highly clean and precise cuts, allowing the blade to remove material on both the up and down strokes. The blades come in 10 and 12 teeth per in. models in both T-shank and U-shank configurations. Woodworking and multi-surface and combo packs are available.
