Angle grinders are versatile power tools that can be used for a variety of tasks, such as cutting, grinding, polishing, and sanding metal, concrete, stone, wood, and other materials. They are also known as side grinders or disc grinders, and they come in different sizes, shapes, and features. But what is the most common angle grinder among the many options available in the market?
The most common angle grinder: 4.5-inch corded angle grinder
The answer is a 4.5-inch corded angle grinder. This is the most popular and widely used type of angle grinder, as it offers a good balance of power, speed, durability, and versatility. A 4.5-inch angle grinder can handle most of the common tasks that require an angle grinder, such as cutting metal pipes, grinding welds, removing rust, and smoothing edges. It can also fit a variety of discs and attachments, such as abrasive wheels, diamond blades, wire brushes, flap discs, and sanding pads.
A corded angle grinder is preferred over a cordless one for several reasons. First, a corded angle grinder has a consistent and reliable power supply, which means it can deliver more torque and speed than a battery-powered one. Second, a corded angle grinder does not have the issue of battery drain or recharge, which can interrupt the work flow and reduce the performance of the tool. Third, a corded angle grinder is usually cheaper and lighter than a cordless one, as it does not require a battery pack or a charger.
How to choose the best 4.5-inch corded angle grinder
While a 4.5-inch corded angle grinder is the most common angle grinder, not all of them are created equal. There are some factors that you should consider when choosing the best one for your needs, such as:
Power: The power of an angle grinder is measured in amps, watts, or horsepower. The higher the power, the more efficient and effective the tool is. However, more power also means more weight, noise, and vibration, which can affect the comfort and safety of the user. A typical 4.5-inch corded angle grinder has a power rating of 6 to 11 amps, which is sufficient for most applications. You may need a higher power rating if you plan to use the tool for heavy-duty or professional tasks, such as cutting thick or hard materials, or using large or specialized discs.
Speed: The speed of an angle grinder is measured in revolutions per minute (RPM), which indicates how fast the disc rotates. The higher the speed, the faster and smoother the cutting or grinding process is. However, higher speed also means more heat and friction, which can wear out the disc and the tool faster. A typical 4.5-inch corded angle grinder has a speed range of 5,000 to 11,000 RPM, which is suitable for most applications. You may need a lower or higher speed depending on the type and size of the disc, the material, and the desired finish. Some angle grinders have variable speed settings, which allow you to adjust the speed according to the task and the disc.
Safety: The safety of an angle grinder is determined by the features and design of the tool, as well as the proper use and maintenance of the user. Angle grinders are powerful and potentially dangerous tools, as they can cause injuries from flying sparks, debris, or discs, as well as electric shocks, burns, or cuts. Therefore, it is important to choose an angle grinder that has safety features, such as a spindle lock, a tool-free guard, a soft start, a quick stop, an anti-kickback clutch, and a side handle. It is also important to wear protective gear, such as gloves, goggles, ear plugs, and a dust mask, and to follow the instructions and precautions of the manufacturer and the disc.
Durability: The durability of an angle grinder is influenced by the quality and construction of the tool, as well as the frequency and intensity of the use. Angle grinders are subject to a lot of stress and wear and tear, as they have to deal with high speed, heat, friction, and impact. Therefore, it is important to choose an angle grinder that has a sturdy and robust body, a powerful and reliable motor, a durable and smooth gearbox, and a sealed and dust-proof switch. It is also important to clean and lubricate the tool regularly, and to replace the brushes, bearings, and discs when needed.
Versatility: The versatility of an angle grinder is affected by the compatibility and availability of the discs and attachments, as well as the ergonomics and convenience of the tool. Angle grinders can perform a variety of tasks, as long as they have the right disc and attachment for the job. Therefore, it is important to choose an angle grinder that has a standard arbor size, which is 5/8 inch for a 4.5-inch angle grinder, and that can fit a wide range of discs and attachments, such as cutting, grinding, polishing, sanding, and wire wheels. It is also important to choose an angle grinder that has a comfortable and adjustable handle, a lightweight and compact design, a long and flexible cord, and a convenient and easy-to-use switch.
Angle grinders are useful and versatile tools that can help you with various projects and tasks. The most common angle grinder is a 4.5-inch corded angle grinder, as it offers a good balance of power, speed, durability, and versatility. However, not all 4.5-inch corded angle grinders are the same, and you should consider some factors when choosing the best one for your needs, such as power, speed, safety, durability, and versatility. By following these tips, you can find the best 4.5-inch corded angle grinder that suits your budget and preferences, and that can help you achieve the results you want.
