Dongcheng brand was founded in 1995, earlier than the development of the above-mentioned Dayou, Yate, Ruiqi and other brands, is one of the key backbone enterprises of professional power tool manufacturing in China. Dongcheng was originally just a factory that produced stator and rotor for power tool parts, and in 2001, Dongcheng's stator and rotor had occupied the first place in the market share.

At the beginning of the transformation, Dongcheng was very conservative in developing only three products, which were completed and put on the market after one year. Later, Dongcheng continued to expand its product line and gradually became one of the largest comprehensive power tool manufacturers in China. Dongcheng was once persuaded by Makita of Japan to buy out the product and become Makita's foundry, but Dongcheng finally insisted on his ODM path.

Dongcheng's strong area is the angle grinder, which is very similar to Bosch's angle grinder in appearance. Dongcheng was originally engaged in the repair of power tools, and later independently produced replaceable stator and rotor components, including the stator and rotor components used by Bosch, so the quality of the motor part of Dongcheng angle grinder is trustworthy. However, Dongcheng's entire line of angle grinder products lack safety protection technology, and other technologies such as brushless technology, motor control technology, lithium battery technology, etc., the technology is not yet mature, and it is still in the stage of imitating foreign brands.

The pricing of Dongcheng angle grinder is popular, the price is low, the unit price of the model suitable for home use is about 100 yuan, and the model suitable for factory use is 200-400 yuan, and the quality matches the price. Dongcheng's angle grinder is more common in domestic factories, if the frequency of use is not high, and there is no high requirement for the fineness of the work, you can start Dongcheng's angle grinder.
