An alloy chisel is a tool used for cutting and carving, typically made from high-strength alloy materials. Its shape is similar to a sharp chisel but is more robust and durable. An alloy chisel can be used to cut and carve various hard materials such as wood, stone, metal, etc. It is commonly used in the creation of artworks, sculptures, and buildings.

Electric pick flower hammers are mainly used for surface treatment of hard materials such as concrete and stone, including roughening and chiseling. These tools are particularly suitable for construction and engineering fields, such as the pre-treatment of walls before tiling in high-rise bridges, and the bush hammering of stone surfaces. The design of electric pick flower hammers allows them to effectively handle the surfaces of hard materials, preparing them for subsequent coatings or other treatments, like roughening walls before tiling to increase adhesion. Additionally, these tools are often used for the surface treatment of concrete and stone, such as creating a bush-hammered finish, which is a common technique in architectural decoration to enhance the appearance and slip resistance of surfaces. Overall, electric pick flower hammers are indispensable tools in construction and engineering fields, used for preparing and beautifying the surfaces of hard materials.

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.
