Electric drill: is the use of electric power as a drilling machine. Is the power tool in the conventional products, but also the largest demand for power tool products. Electric drills are designed to rotate only and are especially suitable for drilling into materials that require very little force, such as cork, metal, brick, ceramic tile, etc. The electric drill only relies on the motor to drive the transmission gear to increase the strength of the bit rotation, so that the drill in metal, wood and other materials to do scraping form piercing.
Hammer drill: works by rotation and impact. Can be used on natural stone or concrete. When the hammer drill is working, there is an adjusting knob at the bit chuck, which can be adjusted in two ways: ordinary manual drill and hammer drill. But the impact drill uses the gears on the inner shaft to beat each other to achieve the impact effect, the impact is far less than the electric hammer. It can also drill steel concrete, but it is not as effective.
Electric hammer: It is a kind of electric drill, mainly used to drill holes in concrete, floor slab, brick wall and stone. Professional in the wall, concrete, stone above the drilling, and multi-functional electric hammer, adjust to the appropriate position with the appropriate drill can be used instead of ordinary electric drill, electric pick. Electric hammer is the use of the bottom motor to drive two sets of gear structure, one set to achieve it drilling, and the other set to drive the piston, like the engine hydraulic stroke, produce a powerful impact force, accompanied by the effect of drilling. Power can divide gold from stone.
Wood and metal drilling. > Impact drill
If in addition to concrete drilling, but also in wood and metal drilling, and drilling in the concrete below 10 mm, you can consider impact drilling, impact drilling by helical gear impact, impact is not as good as electric hammer. But at a low price, something like a 500 watt hammer drill is a good choice.
Tighten or loosen screws > > Electric screwdriver
If you often tighten or loosen screws (computer CANTONESE often do this), or punch holes in the wood or iron plate, then you can buy a rechargeable electric driver, it is the most convenient tool in these two aspects. Rechargeable electric driver plus a driver head set, easy to do the job at hand.
Wood or iron plate drilling > > Hand electric drill
We must all know that it is suitable for drilling holes in the wood or iron plate, but do not expect it to drill holes in the concrete wall as much as, it is easy to damage the machine, a hand drill is the most economical power tool, even if it is imported, it only needs a few hundred yuan.
Concrete wall drilling > > Electric hammer
Due to THE cylinder structure of the electric hammer, the hammering force is very high, and with a rate of 1,000 to 3,000 hammering per minute, it can produce significant force, making it easy to drill holes into concrete walls. Equipped with a transfer rod and the head of the ordinary electric drill, it can also complete the function of the electric drill, to achieve the purpose of multi-purpose. It is the speed regulating electric hammer + transfer rod +13 mm electric drill card head, only a few hundred yuan, and then a few commonly used drill, so most of the decoration tasks in your home can be completed by themselves. Suitable for home decoration, the most suitable for the diameter of 10 mm and 10 mm below the hole.
