Key Factors Influencing Purchase of Power Tools

Functional Requirements

Understanding the functional requirements for power tools is crucial in finding the right tool for your job needs. First, determine the type of electric power tools you need, as different tools are suitable for different tasks. Based on your needs and the tasks you frequently undertake, choose the most suitable tools. Distinguish between home and professional use, as most electric tools are designed for professionals, and you should differentiate between professional and general household tools when making purchases. Professional power tools usually have higher power, while general household power tools do not require very high input power.

Branded vs. Non-branded

Choosing well-known branded electric tools usually provides more assurance. They often have better quality control, after-sales service, and long-term support. If you need to engage in long-term, heavy-duty work, you may want to choose tools from reputable brands as they offer better guarantees. If you are using the tools only at home, your primary goal should be sturdy, work-appropriate, and value-for-money tools. Purchasing branded tools with unnecessary features might not be entirely necessary.

Power and Performance

Pay attention to the power and performance of electric tools. Power is typically measured in watts (W), and higher power means more significant performance. Usually, the difference between professional and general household tools lies in power, with professional tools having higher power. However, choose based on actual needs, as excessively high power may lead to waste. Most electric tools are designed for professionals, so differentiate between professional and general household tools when making purchases.

Corded vs. Cordless

Electric tools generally have two main power source types: corded and battery-powered (cordless). Corded electric tools provide a continuous and stable power supply but require a power outlet connection, limiting their mobility. On the other hand, cordless electric tools are more portable but have limited operating time due to battery constraints. Each power source type has its pros and cons; please continue reading below for specific considerations and choose the appropriate power source type based on your usage scenarios and needs.

Battery

If you choose battery-powered tools, pay attention to the battery technology. Lithium-ion batteries are usually a better choice because they have high energy density, longer lifespan, and low self-discharge rate. Before purchasing, make sure to check the battery type, as many electric tools from the same brand often come with the same batteries. Consider their runtime and charging capabilities.

Safety Features

Electric tools should have built-in safety features to prevent accidents and misuse. Ensure that electric tools are equipped with necessary safety features such as overload protection, automatic shut-off function, safety switches, protective guards, etc. These features help reduce the risk of accidents and protect user safety.

The above are the main factors influencing the selection of electric tools. Only by understanding your own needs can you choose the most suitable electric tools to improve work efficiency and safety.

Types of Power Tools

Electric tools are tools that use electric motors or batteries as power sources. They replace traditional manual labor with greater speed and strength through electric power transmission. Below are some of the most popular and practical tools suitable for various environments!

Drill: Used for drilling holes in metal, plastic, and other materials. 

Rotary Hammer: Used for drilling holes in bricks, concrete, artificial or natural stones, etc. Its function can be interchangeable with that of an electric drill. Light-duty drills often use SDS-PLUS chuck and drill bits, while medium and heavy-duty hammer drills use SDS-MAX chucks and drill bits and can be equipped with chisels.

Impact Drill: Mainly used for drilling holes in hard materials such as bricks and concrete. When the impact mechanism is closed, it can also be used as a regular electric drill.

Sander: A sander is a power tool used for sanding or smoothing surfaces by abrasion. It is commonly used in woodworking and other industries to remove rough edges, old finishes, or imperfections from various materials such as wood, metal, or plastic.

Angle Grinder: Also known as a grinding machine or disc grinder, mainly used for grinding steel, metal, and stone. Common grinding disc diameters are 100mm, 125mm, 180mm, and 230mm.

Saws: Mainly used for cutting metal, wood, plastic and other materials. Jig saw is ideal for cutting precise straight or curved lines. Reciprocating Saw and  Circular Saw are also the common kinds.

Impact Wrench and Screwdriver: Both are used for assembling and disassembling threaded connectors. The transmission mechanism of the electric wrench consists of a planetary gear and a ball screwdriver. The electric screwdriver uses a tooth clutch transmission mechanism or a gear transmission mechanism.

Trimmer: Used for edge milling, drawing, and carving on wood.

Corded Power Tools vs. Cordless Power Tools

Electric tools can be categorized into corded and cordless types based on their power sources.

Corded Power Tools

Corded power tools, also known as plug-in electric tools, are powered by connecting them to a power outlet using a power cord. This means that corded electric tools can work continuously without worrying about battery depletion.

Advantages:

Continuous Power: No need to worry about battery running out; they can work continuously.

Higher Power: As they are connected to a power source, corded electric tools usually have higher power and performance.

Relatively Lower Price: The most powerful corded electric tools are usually cheaper than their cordless counterparts.

Lighter Weight: Since they do not have heavy batteries, they tend to be lighter than cordless models.

Disadvantages:

Limited Mobility: The length of the power cord limits their range of use, making them less suitable for outdoor or places without power outlets.

Less Portable: Plug-in electric tools require a power cord connection, making them less convenient for portability and use.

Cordless PowerTools

Cordless power tools, also known as battery-powered electric tools, use built-in batteries as their power source. These tools do not require a power cord connection, making them more portable and suitable for both indoor and outdoor use. Common cordless electric tools include cordless drills, cordless saws, cordless angle grinders, etc.

Advantages:

Portability and Flexibility: No need for a power cord, making them suitable for indoor and outdoor work.

Ease of Carrying: Cordless electric tools are more portable, making them easier to carry and move around.

Higher Safety: They are generally safer to use than corded tools.

Disadvantages:

Battery Life: Battery-powered tools have limited battery capacity and require regular charging or backup batteries.

Lower Power: Compared to corded electric tools, cordless models may have relatively lower power.

Relatively Higher Price: Cordless electric tools are often more expensive than their corded counterparts.

Brushed Motor vs. Brushless Motor

In electric tools, "brushed" and "brushless" refer to the type of motor used in the tool.

Brushed Electric Tools: These tools have a motor with small metal brushes driving the rotation.

Brushless Electric Tools: These tools have a motor equipped with an electronic circuit board and sensors.

Brushless electric tools have less friction and heat accumulation than brushed motors, making them more efficient and powerful. Therefore, brushless electric tools tend to have a longer lifespan, higher efficiency, and require less maintenance, but they also come at a higher cost.

Comparison of Advantages:

Brushed Motor: Relatively simple and lower cost, but shorter lifespan and lower efficiency.

Brushless Motor: Longer lifespan, higher efficiency, less maintenance required, but more complex and higher cost.

In conclusion, when purchasing electric tools, consider your functional requirements, whether they are for home or professional use, the brand reputation, power and performance, corded or cordless, battery type, safety features, and the type of motor used. These factors will help you make an informed decision and choose the most suitable electric tools for your needs.
