24pcs Spiral Tooth Scroll Saw Blades for Metal Wood Plastic Sawing Wood Cutting Jewelry Making Metalworking Crafts 130mm (1 - 8)

Sharp teeth withstand loads and increase cutting speed – cutting speed and finish depend on the material thickness and the number of teeth per inch. The thicker the object being cut, the thinner the blade should be. Sizes 1, 2, and 3 are recommended for sawing metal; sizes 4, 5, 6, and 7 are suitable for sawing wood; and size 8 can be used for sawing plastic. Forged from carbon steel with a machined finish, it offers high hardness and strength and is hardened to stay sharp longer. Easily replace damaged or worn saw blades. These blades cut all around with 360-degree cutting capability – arc sawing is easy and the blade won't jam – ideal for cutting and shaping wood, jewelry making, metalworking, crafts, and more. To install the saw blade, insert it into the small hole at the rounded end of the saw blade holder. Saw blades are available in sizes 1-8#, with a small difference in thickness. The spacing in the installation hole is controlled by the thumbscrew and hex screw on the back.
