The four main types of power tools are:
Electric power tools: These are tools that are powered by electricity and require a power source such as a wall outlet or battery. Examples of electric power tools include drills, saws, sanders, and routers.
Pneumatic power tools: These are tools that are powered by compressed air and require an air compressor to operate. Examples of pneumatic power tools include nail guns, impact wrenches, and paint sprayers.
Hydraulic power tools: These are tools that are powered by hydraulic pressure and require a hydraulic power source such as a pump. Examples of hydraulic power tools include jackhammers, hydraulic presses, and pipe benders.
Gas-powered tools: These are tools that are powered by gasoline and are typically used for outdoor applications such as lawn care and landscaping. Examples of gas-powered tools include chainsaws, leaf blowers, and lawn mowers.
