What's the difference between Bosch and Dongcheng electric drill?

The difference between Bosch and Dongcheng electric drill is:

1, different brands

Dongcheng electric drill is a domestic brand, and it is one of the key enterprises specialized in manufacturing electric tools in China. Bosch is an imported brand and one of the largest industrial enterprises in Germany.

2. The price and quality are different.

Bosch electric drill is an imported product with advanced production technology. Dongcheng electric drill is made in China. Relatively speaking, the quality of Bosch electric drill is better, and the price of Dongcheng electric drill is lower.

3, the development cycle is different.

Bosch is a German company with a long history, while Dongcheng is an emerging domestic enterprise. Therefore, the development cycle of Bosch electric drill is relatively long, the technology is relatively advanced and mature, and the development cycle of Dongcheng electric drill is relatively short.

4, the production process is different

Because Bosch has developed for more than 100 years, its production technology is advanced, and it has the ability to produce its own brand and experienced technical team. Dongcheng electric drill is a new electric tool company. Many production technologies are imported and imitated from other brands, so its production technology is more advanced and mature.

5. The main purpose is different.

Bosch electric drill is mostly used in large-scale projects because of its advanced production technology and good quality. Dongcheng electric drill is relatively low in price and is mostly used as a household tool.

Bosch is one of the largest industrial enterprises in Germany, engaged in automobile technology, industrial technology, consumer goods and construction technology industries. 1886 When Robert bosch, who was only 25 years old, founded the company in Stuttgart, he designated the company as a "factory for precision machinery and electrical engineering".

Headquartered in Stuttgart, southern Germany, Bosch has more than 230,000 employees in more than 50 countries. Bosch is famous for its innovative and cutting-edge products and system solutions.

Dongcheng electric drill is a county-level electric tool company, located in Lvsi, Qidong, Jiangsu. Founded in 1995, it is one of the key enterprises specialized in manufacturing electric tools in China, and the governing unit of electric tools branch of China Electrical Appliance Industry Association.

The company has a complete industrial production base, covering an area of112,800 square meters and a building area of 58,000 square meters. Has a modern industrial plant and first-class production and testing equipment; At the same time, it has a group of professional senior engineers, a team of middle and senior managers and technicians; More than 2,300 employees.

Extended data:

Classification of electric drills:

1. Hand electric drill: the power is the smallest, and the use range is limited to wood drills and electric screwdrivers. Some hand drills can be changed into special tools according to their uses, with more uses and models.

2. Impact drill: The impact mechanism of impact drill has two types: dog tooth type and ball tooth type. The ball impact drilling rig consists of a moving disk, a fixed disk and steel balls.

The turntable is connected with the spindle through threads, and there are 12 steel balls on the turntable; The fixed disk is fixed on the shell with pins and has four steel balls. Under the thrust, the 12 steel ball rolls along the four steel balls, which makes the cemented carbide drill produce rotary impact motion and can drill holes in brittle materials such as bricks, blocks and concrete. The pin is separated, so that the fixed disk and the driven disk rotate together without impact, and it can be used as an ordinary electric drill.

3. Hammer drill (electric hammer): It can drill holes on a variety of hard materials and has the widest application range.

The difference between hand drill, impact drill, hammer drill and electric pick;

1, the hand electric drill only relies on the motor to drive the transmission gear to increase the rotation of the drill bit, so that the drill bit can scrape into metals, wood and other substances.

There are two ways for impact drill to work: adjusting knob, adjustable drill and impact drill. The impact drill uses the gears on the inner shaft to jump each other to achieve the impact effect, and the impact force is far less than that of the electric hammer. You can also drill reinforced concrete, but the effect is not good.

2. Hammer drill (electric hammer) is different. It uses the motor at the bottom to drive two sets of gear structures, one for drilling and the other for driving the piston, just like the hydraulic stroke of the engine, which produces a strong impact force with the effect of drilling. Strength can turn stone into gold.

3. The electric pickaxe makes the motor drive the swing hammer to run in the form of bouncing, so that the pickaxe has the effect of digging the ground. Hydraulic pump pickaxe uses the gas pressure transmitted by air compressor to drive the pump hammer in electric pickaxe to rebound, thus producing the effect of chisel hitting the ground, but electric pickaxe is only a chisel, and its pickaxe does not rotate.

In short, electric drills can only drill holes, and impact drills can also have a slight hammering effect. Hammer drill can drill, and the level of hammer is higher, while electric pick can only hammer but not drill.
