Cordless angle grinders are especially useful for projects they can be used anywhere, including those with limited access to electrical outlets or where there is no electricity at all. [1]
Cordless Angle Grinder vs Corded
Purpose
When it comes to grinders, the two most common types are corded angle grinders and cordless angle grinders. Each one has its own advantages and disadvantages you should consider when deciding which type is best for your projects.
Corded angle grinders offer more power than their cordless counterparts due to the fact that they are always plugged in and have a higher amperage rating. This means they can easily tackle most grinding tasks including cutting, shaping, and polishing metal. Corded angle grinders also have the benefit of being able to work continuously without having to be recharged. [3]
Disc Size
The other major difference between corded and cordless angle grinders is the type of disc that can be used. Corded angle grinders typically use larger discs than their cordless counterparts due to the higher power output. These larger discs are usually 7 inches or more in diameter and are great for tasks such as cutting, grinding, and polishing metal and stone.
Cordless angle grinders, on the other hand, typically use smaller discs that are 4.5 inches or less in diameter. These smaller discs are great for tasks like grinding small amounts of material or polishing surfaces. [3]
Depth of Cut
Another factor to consider when choosing the best type of grinder for your project is the depth of cut. Corded angle grinders typically provide more power and can handle deeper cuts than cordless models, which means they are better suited for projects that require cutting thicker materials.
Cordless angle grinders, however, are great for tasks that require more precision and lighter cutting, such as trimming tile or grinding small amounts of material. [3]
Wheel Orientation
The orientation of the wheel is another factor to consider when choosing between corded and cordless angle grinders. Corded angle grinders typically have a higher torque rating than their cordless counterparts so they can keep a heavy-duty wheel spinning in one direction for extended periods of time.
Cordless angle grinders, on the other hand, can be used for lighter-duty jobs that require a wheel to spin in both directions. This makes them perfect for tasks such as polishing stone or metal surfaces. [3]
Speed
The last factor to consider is speed control. Corded angle grinders offer more torque and power, but they typically don’t have the kind of variable speed control that cordless models do. This means they are better suited for projects that require a powerful, consistent cutting or grinding speed.
Cordless angle grinders, on the other hand, offer more variable speed control, which makes them great for tasks that require precision and accuracy. This can be especially useful when cutting delicate materials or polishing surfaces. [3]
Size
The size and weight of the grinder is also an important factor to consider. Corded angle grinders are typically heavier and bulkier than their cordless counterparts due to the need for a power cord. This makes them better suited for larger projects that require more torque and power, but they can be harder to maneuver in tight spaces.
Cordless angle grinders, on the other hand, are usually lighter and more compact than corded models. This makes them great for smaller projects that require precise control and accuracy. [3]
Weight
The weight of the grinder is also an important factor to consider. Corded angle grinders are usually heavier than their cordless counterparts, which can make them difficult to maneuver in tight spaces. Cordless angle grinders, on the other hand, are typically lighter and more compact, making them easier to use for smaller projects. [3]
Power
The power source of your grinder should be considered as well. Corded angle grinders will always need to be plugged into a power source, so you’ll need to make sure there is an outlet nearby. Cordless angle grinders, on the other hand, have rechargeable batteries that allow them to be used anywhere. [3]
Scale of Work
You should consider the scale of your project when choosing between a corded and a cordless angle grinder. For larger projects that require more torque and power, a corded angle grinder is usually the best option. But if you’re looking for something more portable that can handle smaller tasks with greater accuracy, then a cordless angle grinder might be the better choice. [2]
Ease of Use
Think about the ease of use. Corded angle grinders are usually more powerful and can handle larger projects with ease, but they can be harder to maneuver when working in tight spaces. On the other hand, cordless angle grinders are typically lighter and more portable, making them easier to use for smaller tasks. [2]
Versatility
Consider the versatility of each type. Corded angle grinders are great for larger projects and can handle a variety of tasks from grinding to polishing metal surfaces. But cordless angle grinders offer more portability and are perfect for tasks that require precise control, such as trimming tile or grinding small amounts of material. [2]
Functions
Lastly, think about what functions you need your grinder to have. Corded angle grinders usually come with more advanced features such as variable speed control and spindle lock for added safety.
