Power tools are an important invention to improve work efficiency in the development of human civilization. They have developed rapidly and iteratively since 1895. In 1895, CE&Fein produced the world's first power tool, which was an electric drill with a shell made of steel and powered by a DC motor. In the 1960s, with the development and progress of science and technology and the vigorous development of the world economy, the use of power tools began to rise, power tool manufacturing took the lead in Europe and the United States and other developed countries to achieve industrialization. In the 1970s, Japan quickly became one of the main producers of power tools with relatively low production cost advantage. In the late 1980s, with the gradual maturity of battery charging technology, power tools began to gradually move from cordless to cordless. In 1978, Bosch invented the first cordless electric drill. But it wasn't until Makita introduced brushless motors to the power tool industry in 2004 and Milwaukee introduced lithium battery power in 2005 that cordless power tools began to take off.
