Jigsaw blades come in two main types: U-shanks or T-shanks called SDS. The T-shape jigsaw blade doesn’t need a tool to fasten it to the jigsaw. The U-shaped blade is used in older models. Most new jigsaws can use either jigsaw blade type. Some jigsaws may have different fittings – Makita has dedicated fittings. • According to its brand and its type, your jigsaw has a quick fixing system allowing compatible blades. On most electric machines, the blades usually attach without tools. Some older models require a set screw to be tightened. • Jigsaw blades vary in shape, denture, length and material for cutting hard or soft wood, soft metals like aluminum, steel HSS, bimetal, plastic or ceramic tile. • When cutting wood, choose a 6–10 tpi blade because the wider low areas between teeth (gullets) help clear sawdust. • Cutting metal or plastic sheets requires a higher tooth count and slower cut speed. • A 6-tpi blade will cut faster and moves straighter through thick material, but can create more chip-outs than a 10-tpi blade. • The blade cutting teeth are stated as teeth per inch (tpi). The teeth are different - heavy, medium, fine or angled, straight. The teeth are usually sharpened in a triangle facing upwards. • Jigsaw blades can be made of hard steel, a bi metal, or coated like tungsten, carbide powder. • Cut material with the good side down. Because the jigsaw cuts on the up-stroke, chipping occurs on the upper-facing surface of the material. • Also, there are specialty toothed blades that cut downward, or for cutting curves and circles. • If the work consists of unique material, then a special blade is available. You'll recognize it right away thanks to its narrow form and forward facing teeth. • Fine-toothed blades are for the hardest metals. When using the finest toothing, cut at a low speed with cutting oil, otherwise the blade can carbonized from the heat. • Jigsaw blades are made to cut for ceramic and glass. These can be toothless and use water or oil to cool. • • Hi! I’m Blair Gilbert, aka MR. HARDWARE.
