Angle grinders are the unsung heroes of the toolbox — the underappreciated weapon in the arsenal of any person looking to have a well-rounded lineup of tools. Using an impressive array of gadgets and attachments, an angle grinder makes it easy to prepare surfaces for painting, carve wood, cut metal and complete a host of other simple DIY tasks.

The DeWalt Angle Grinder Tool is a durable, versatile tool to start with. It gives you all the power you need to get the job done.

Angle grinders come in wheel diameters that range from 4.5 to 9 inches. Larger angle wheels aren't necessary for the occasional DIY-er, but professional wood and metal workers might want a larger, more versatile diameter.

Power is measured in horsepower (hp), amps, watts and rotations per minute (RPMs).

A carry case keeps the angle grinder and all of its accessories in one convenient place. It makes transport to a job site easier, too.

A safety lock prevents the grinder from starting accidentally. This might be added in the form of a lockout button or safety switch.

The gears that run the grinder take a lot of power and motion during operation. Make sure the angle grinder you select has durable metal gears instead of cheap nylon or plastic.

The wheel starts in a burst of energy that can be jarring. A soft start eases the grinder into operation.

Some heavy-duty angle grinders can weigh as much as 16 pounds. For versatile power in a more lightweight package, 4.5-inch grinders are good. They weigh between 4-5 pounds.

When angle grinders are polishing metal or removing rust, dust can get into the tool and cause it to break down. Dust guards keep small particles from interfering with the operation.

The price varies dramatically depending on the size of the angle grinder and whether or not it's cordless. Expect to pay $25 to $300.
