There are two types of electric power tools: handheld and portable. Hand-held power tools are more flexible, convenient, and widely used. Many varieties have become essential woodworking tools for production and life. There are many brands of ideal power tools. According to the functions of power tools, the purpose is divided into different types. Let me explain to you what are the common types of power tools.
Power tools are mainly divided into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tool kits include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.
Electric drill and impact drills
Electric drill is a drilling tool that uses electricity as power. It is a conventional product in power tools and the most in demand cheap power tool product. The annual production and sales volume accounts for 35% of China's power tools. The numbers refer to the maximum diameter of the drill bit drilled on steel with a tensile strength of 390N/mm2. The maximum drilling diameter of non-ferrous metals, plastics and other materials can be 30-50% larger than the original specifications. Electric drills can be divided into hand drills, impact drills, and rotary hammer drills.
The impact electric drill adds an impact function to the electric drill. In addition to wood, metal and other materials, it can also be used for stone drilling.
Electric grinder is a tool for grinding with a grinding wheel or disc. There are straight electric grinders and electric angle grinders.
Miniature angle grinder is a portable carpentry power tools that uses glass fiber reinforced plastic for cutting and grinding. It is mainly used for cutting, grinding and brushing metals and stones.
Hand held metal straight grinder is used in mining and metallurgy, building materials, chemical industry and metallurgy. The purpose is to process cavity molds and fixtures. The types are pneumatic straight grinder and pneumatic straight grinder.
Electric wrench and electric screwdriver
Electric wrench and electric screwdriver are used for loading and unloading threaded connections. The transmission mechanism of the electric wrench is composed of a planetary gear and a ball spiral groove impact mechanism. The electric screwdriver adopts a jaw clutch transmission mechanism or a gear transmission mechanism.
The electric hammer is an electric electric rotary hammer drill with a safety clutch attached with a pneumatic hammer mechanism. Electric hammers are used for drilling, grooving and roughening concrete, brick walls and building components. Combined with expansion bolts, it can improve the installation speed and quality of various pipelines and machine tools.
Concrete vibrators are used to compact concrete when pouring concrete foundations and reinforced concrete components to eliminate air holes and improve strength. Among them, the high-frequency disturbance power of the electric direct-coupled vibrator is formed by the rotation of the eccentric block driven by the motor.
It is used for planing wood or wooden structural parts. It can also be used as a small planer when installed on a bench. The knife shaft of the electric planer is driven by the motor shaft through a belt.
