Cordless Drills History let us know more about drills

 The use of electric-powered drilling equipment. Is a power tools in the conventional products, but also the greatest demand for cordless drills products. The annual production and sales accounted for 35% of electric tools in China.Main specifications 4,6,8,10,13,16,19,23,32,38,49 mm drill and so on, refers to a tensile strength of steel on the 390N/mm2 diameter drill holes. Pairs of non-ferrous metals, plastics and other materials than the original diameter of the largest drilling big size of 30 ~ 50%

 Cordless drill works by rotating magnetic or electromagnetic reciprocating small-capacity motor rotor doing work to do cutting operation of the magnetic field, through the transmission-driven operation device, turn the gear wheel to increase the power drill so that drill shaving surface, better ripped through objects .

 The birth of the world's power tools drill product is from the beginning - and in 1895, the German Fein company has developed the world's first DC-drilling, which sets the weight of 14 kg drill, casing is made of cast iron can only be drilled on a steel plate 4 mm hole. Subsequently, there were three-phase power frequency (50Hz) electric drill, but the motor speed failed to break through 3000r/min.

In 1914, there has been a single-phase series excited motor-driven drill, the motor speed up to 10000r/min above.

In 1927, there have been power supply frequency of 150 ~ 200Hz IF drill, both with single-phase series excited motor high speed advantages, but also has three-phase power frequency electric motor structure, simple, reliable advantages, but need to use for the IF current electricity, the use is restricted.

60 years, there has been to use nickel-cadmium batteries for power supply without power cord the battery-type drill. To the mid-to late 70s, lower prices due to the battery, charging time is shortened, which drills in Europe and the United States, Japan, widely used.

Electric drill to make the first cast iron shell, the latter to use aluminum for housing. 60 years, thermoplastic engineering plastics in the drill gain applications, and achieved a double insulated drill.

60 years have emerged electronic speed drill. This drill components, such as the use of thyristor composed of electronic circuits to switch pressed the button has been pressed into the depth to adjust the different speed, so that the use of drills when the object to be processed by different (such as material is different hole diameter , etc.), choose a different speed.
