- High hardness: Each punching tip is individually heat treated to harden and strengthen the carbon steel, delivering superior hardness and durability. - Non-slip handle design: The knurled round shank provides a secure, non-slip grip for precise control and safe handling during use. - Tapered punch point with starting dimple: The punching tip features a dimple to create an exact starting spot for drilling, reducing wandering and improving accuracy. - Broad compatibility: Works effectively on cast iron, mild steel, brass, bronze, copper, aluminum, wood, plastics, and polymers. - Usage scenarios: - Use the starting dimple to locate and mark the drill point on metal brackets or housings, preventing drill bit wandering. - Start holes in aluminum, copper, or brass sheets with confidence for clean, aligned drilling. - Mark and position holes in wood or plastic components for precise hole placement in prototypes or assemblies.
