An angle grinder is a type of power tool that features a smaller or larger sanding disc inside. Most have a good line of sight that helps you keep an eye on that sanding disc and see how well it works on your project. These grinders come in different sizes, but the size relates to the size of the disc that it works with and not the grinder itself. Our search led us to name the Bosch CSG15 5-Inch Concrete Surfacing Grinder as the best angle grinder because it has a simple design that improves your line of sight and a 12.5 amp motor.

How to Choose the Perfect Angle Grinder – Buying Guide
Angle grinders let you polish, make cuts and do other things, but you may wonder how to pick the right angle grinder for you. Take a look at our list of the top features found in angle grinders before you start your search.
Smaller grinders are available in 4-1/2 inch and 5 inch sizes. This size refers to the size of the grinding disc itself. Though smaller models are great for most home projects, professionals may need grinders with a seven-inch disc.
Revolutions per minute, or RPM, tells you how many revolutions the grinding disc will make in a single minute. The RPM speed on most models ranges from 4,000 to more than 10,000. The faster it goes, the faster you can handle the job at hand, but faster motors may also overheat.
Prevent accidents with an angle grinder that features an electric brake. This will cause the grinder to automatically shut off in two seconds or less when the motor overheats or there are other issues with the motor.
Look at what comes in the box and what optional attachments are available. Certain discs can help you with grinding, polishing, sanding, cutting and grinding.
