Electric impact wrench and electric screwdriver are common electric tools, difference between which is mainly reflected in difficulty of use.
The impact tool uses an impact mechanism within structure to transmit torque to a standard threaded part. If impact tool does not require a torque limiting mechanism, price is low. The reaction moment of tool to operator's hand is small, and operation is simple.
Impact wrenches can be divided into two categories based on their use: one is used by auto mechanics to remove parts such as engine cylinders, and other is used to install certain special parts or equipment in industry.
Power screwdrivers, also called power screwdrivers and power screwdrivers, are power tools for tightening and loosening screws and nuts. The electric screwdriver directly transfers torque received by standard parts to operator's hand. To prevent tool from rotating, operator needs to provide same amount of reverse torque to tool, which is labor intensive. One-handed operation, M6 is already limit.
When it comes to electric screwdrivers, some people often mistake electric drills and electric screwdrivers for same thing. Now can you tell difference?
