The best angle grinder is a tool managing all the tasks your current project presumes. Often, getting an overkill appliance will mean the waste of money. The best metal grinder 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 dependance. Let’s list the main pros and cons of the corded angle grinder vs. the cordless one.
- Power. The corded models are usually more powerful and can deal with harder materials like solid wood, tile, etc. Still, the cordless angle grinder wins the battle in the 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!

Where to Apply an Angle Grinder
An angle grinder is a multi-task tool that can accommodate various wheels fit for a different purpose. Here’s a brief list outlining what is an angle grinder used for:
- cutting. The high torque, sharp blades and sturdy build allow an angle grinder 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. Apply a grinding disc and sharpen a knife, scissors or any other blade.
- metal. A powerful angle 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. An angle grinder 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.
- 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 angle grinder at the object and start the tool.
- grinding. Install a wire wheel or a wire brush to an angle grinder, connect a power source, and direct the grinder onto the surface. Be careful not to press the grinder too tight.
- sharpening. Install a grind wheel, hold the tool in your hand, connect the power and take the blade near the edge of the disc. Make sure not to bring it 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 safely outside.
- Protective equipment. Use workwear 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 correct disc for your task and use the grinder according to the manual.
