Angle grinders are unique devices that have a special role in the world of power tools. This is not a tool that every homeowner needs. It’s not like a power drill; a tool that almost everyone can use. But for anyone who works on cars, restores anything made of old metal, or who may need to burr metal or remove rust deposits, an angle grinder is the essential tool. Some construction projects require heavy duty versions of the angle grinder. But for many people, even professional contractors on particular projects, economical but powerful versions of this tool, like the Dewalt DWE402 Angle Grinder, will fill the bill.
Angle grinders are used in all kinds of metalworking and in many phases of construction. Auto repair services and auto body shops use them. Construction professionals and homeowners working on improvement projects will have many applications for this versatile tool. Metal artists and sculptors use this tool. Fitted with different blades, angle grinders can be used for grinding, leveling and polishing metal, but they also can be used on concrete, stone, and tile.
There are different sizes and styles of grinders. Some are attached to workbenches and others are portable. Some are electric, some are gas-powered and some are pneumatic. Handheld, portable electric angle grinders like the Dewalt DWE 402 offer tremendous flexibility to reach difficult places, to work in small spaces and to handle a wide variety of applications.
