Similarities and differences between electric drill
The electric drill only has a rotation method, and is particularly suitable for drilling holes on materials that require little force, such as cork, metal, brick, and ceramic tiles. Electric hammers rely on rotation and thrashing to work. A single thumping force is very high and has a thumping frequency of 1,000 to 3,000 per minute, which can produce significant force. Compared with impact drills, electric hammers require minimal pressure to drill into hard materials, such as stone and concrete; especially harder concrete impact drills rely on rotation and impact to work. A single impact is very slight, but a frequency of more than 40,000 impacts per minute can produce a continuous force. Impact drills can be used on natural stones or concrete. They are versatile because they can be used in either 'single drill' mode or 'impact drill' mode, so it is a basic power tool worth choosing for professionals and do-it-yourselfers. Electric drills, electric hammers, and impact drills are used to make holes. Electric hammers are generally used to drill holes in concrete and other hard objects. The drill bit is made of alloy steel. It has the function of a hammer while drilling. Electric drills are used to drill holes in relatively tough objects. The drill bits are generally steel. The impact drill has the functions of an electric hammer and an electric drill. It can be used as an electric hammer and an electric drill. There are also two kinds of drills. The difference between electric drill and electric hammer The essential differences between electric drills and electric hammers are as follows: (1) The volume is different. (2) Of course, the weight is also different. The electric drill has only the number of rotations between the motor (rotor + stator) and the gear. The electric hammer is different. It should be called a 'hammer'. So it has an impact force and can drill hard materials such as concrete and stone. Therefore, the volume of the electric hammer is a little larger than that of the electric drill, which should be an important accessory such as a cylinder, a connecting rod, a piston and the like. The electric drill can only drill wood, iron, plastic and other materials. The electric hammer uses the movement of the piston to compress the gas to impact the drill bit.It does not require much effort from the hand.It can open 6--100mm holes in hard materials such as concrete, brick, stone, etc. , But it cannot open holes in the metal. Electric drills are non-impact and require human pressure to open holes in materials such as metal and wood, with a diameter of 6-50 mm. The advantage is that the vibration is small, the precision of the opening is high, and the price is not high. In addition, they use different drills, the former is an alloy-inlaid drill, the latter is an ordinary cutting drill. Both electric hammer and impact drill can make holes in concrete structures. Both have the function of piston movement, and the electric hammer is suitable for large calibers such as more than 30MM. The advantages are high efficiency, large aperture and long drilling depth. The disadvantage is that the vibration is large, which has a certain degree of damage to surrounding structures. Impact drills are suitable for small diameters of about 25 mm and short drilling depths. Such as installing expansion bolts. The damage to surrounding structures is very small. For air-conditioning installation, electric hammers should be used except through-holes. Electric drills should be used in other locations. Difference: The electric hammer drill bit is assembled with a locking clip, which is simple and does not require any tools. The impact drill requires a special key to tighten.
