Bosch has a long and distinguished heritage in manufacturing jig saws and jig saw blades. When a Bosch engineer installed a blade on his sewing machine in 1946, the idea for the jig saw was born. Bosch invented the now industry-standard T-shank interface system decades ago. And as a leader in blades, Bosch offers a broad range of blades that cut wood, metal, and other materials (such as plastic, ceramics, Plexiglas, and laminate). Bosch Jig Saw Blades feature blade material from high-carbon steel to high-speed steel, bi-metal, tungsten carbide, carbide grit, and diamond grit. Bosch also provides specialty blades for applications such as fiberglass, cement board, porcelain (including tile), carpet, and even cast iron.
