Corded angle grinders rotate grinding wheels to remove surface material or rotate cut-off wheels to cut through material. Their head is set at a right angle to the tool body, making them more compact than vertical grinders and allowing for better visibility of the wheel and the work surface. Grinders with side handles allow a two-handed grip to improve stability and control. Angle grinders are commonly used to grind welds, prepare metal and concrete surfaces, bevel cutting tools and material edges, cut metal plates and pipe, and polish concrete, stone, and metal. These tools plug into an outlet to allow longer run times than cordless tools, so they are well suited for repetitive tasks and applications where portability isn't a concern. They maintain full power during operation and don't have batteries that require recharging.
