Select impact drill:
Impact drill has two functions: flat drill and impact drill. In flat drilling mode, different drill bits can be installed to drill holes on the surface of light materials such as plastic, wood, thin metal, etc. in this mode, it can also install the elastic screw of the bit head, such as assembling furniture, installing door handle, dismantling household appliances, etc. The drill bit installed in percussion drilling mode is mainly used to drill holes in lightweight concrete, such as drilling holes on brick walls or ordinary cement walls to install hanging pictures and hardware.
Choose the hammer:
There are two kinds of electric hammers: direct current and alternating current. Lithium electric hammers are more suitable for household use because they do not need to plug in electricity. Generally speaking, the electric hammer has two modes: flat drilling and hammer drilling. The flat drilling mode is similar to the flat drilling function mode of impact drill. In hammer drilling mode, holes can be drilled in concrete.
Difference between impact drill and electric hammer:
1) The impact mode is different. The impact drill is produced by the impact of two impact gears, while the impact of the electric hammer is caused by the movement of the cylinder piston, so the impact force of the electric hammer is far greater than that of the ordinary impact drill.
2) In terms of function, lithium electric hammer has more functions, which can integrate the functions of screwdrivers, electric drills and electric hammers.
If you are drilling on some soft materials, it is recommended to choose impact drill.
If it is necessary to drill holes in hard walls such as concrete, it is recommended to use electric hammers.
