The best angle grinder is a tool managing all the tasks your current project presumes. Often, getting an overkill appliance will mean a waste of money. It might turn out to be too heavy and powerful for wood polishing. The less powerful models can become helpless at hard stuff like concrete, etc.
The main difference between the types of such equipment is their cord dependence. Let’s list the main differences between a corded angle grinder vs. a cordless one.
- Power. Corded models are usually more powerful and can deal with harder materials like solid wood, tile, etc. Still, a cordless angle grinder wins the battle in places without the electricity source or where the outlet is too far.
- Portability. While a battery-equipped device is considered more portable due to no cord limit, it also has an additional battery weight. At height works, this might become a drawback.
- Cost. The cordless tools are usually pricier than the cabled ones. That’s a positive point for the corded angle grinder.
Picking one of the top-rated angle grinders is always a matter of weighing pros and cons. Do it efficiently, with the help of our smart angle grinder reviews!

DewaltT DCG413B — Best 4 – ½ inch angle grinder
This sturdy middle-class tool can handle multiple works and materials including concrete grinding and solid wood cutting. It has a powerful low-vibration motor emitting 9,000 RPM at zero load and a maximum battery capacity of 20V.
The unit has several safety mechanisms. The paddle switch works seamlessly leading the disc to stop in a few seconds upon releasing the paddle. If the operation is threatened in any way (the disc is prone to be bent, the mechanism is cluttered, etc.), the kickback brake mechanism stops rotating automatically. Another safety thing, before turning on the angle grinder tool again, requires turning a trigger switch full-cycle.
The tool has a comfortable handle of a good diameter to fit almost any hand. There is also a user hand protection ring on the handle to prevent injury from the disc and/or the flying dust and debris.
- A magnet-equipped motor has a high torque and is maintenance-free.
- The motor isn’t loud, emitting little noise when running with a light load.
- Good ergonomics and compact size result in less user fatigue.

Where to Apply an Angle Grinder
An angle grinder is a multi-tasking tool that can fit a variety of wheels for different purposes. Here is a brief list describing what this tool is used for:
- Cutting. The high torque, sharp blades, and sturdy build allow the device to perform straight cuts efficiently.
- Grinding. Removing the remnants of the concrete after concrete casting work or getting rid of the rust on the metal or paint excess is another frequent task an angle grinder is applied for.
- Sharpening. A grinding disc can sharpen a knife, scissors, or any other blade.
- Metal. A powerful grinder can cut through thick metal sheets and rods, make cutouts, etc.
- Cement and concrete. Slicing cement boards is easy with a high-torque sturdy angle grinder.
- Tile. It cuts through tile efficiently, however, depending on the tile type, the edge might be crumbled.
- Plastic. A grinder can be used at all types of plastic objects, including pipes, boards, and so on.
- Wood. A grinder tool can replace a circular saw when dealing with wood. However, its capacity is limited by a guard/disc diameter — it won’t go deep into a large log.
How to Use Angle Grinder?
Angle grinders are used for different purposes. Here’s the advice specifying how to use this tool in each case:
- Cutting. Make sure the object is immobilized. Install the blade into the grinder tool (by means of a wrench, if needed), connect it to the power supply (or insert the battery), point the device at the object, and start the tool.
- Grinding. Install a wire wheel or a wire brush to the grinder, connect a power source, and direct the grinder onto the surface. Be careful not to press the grinder too tight.
- Sharpening. Install a grinding wheel, hold the tool, connect the power, and take the blade near the edge of the disc. Make sure it’s not too close.
- Safe worksite. The place must be free from secondary objects, clean, and well illuminated. Good ventilation, no exposure to water, open circuit, or fire are mandatory. Children and animals must be outside.
- Protective equipment. Use work clothing and protect your eyes, open skin, respiratory system, and hands.
- Grinder condition. Check the tool integrity, its cable, guard position, the handle connection. Clean the ventilation slots.
- Safe use. Choose the necessary disc and use the grinder according to the instructions.
