U-shaped chisels are primarily used for creating grooves in walls, concrete, stone, and other materials in construction and renovation projects. These tools are typically mounted on electric hammers and are used for breaking and creating grooves to facilitate the subsequent installation of electrical wiring, pipes, or other construction tasks. The design of U-shaped chisels makes them particularly suitable for applications requiring precise control over groove depth and width, such as creating slots in concrete or positioning fixtures. Additionally, some advanced U-shaped chisels are equipped with groove depth limiting functions, which help improve the accuracy and efficiency of grooving operations and reduce the skill requirements for operators.
