1) Hardness: Each punching tip is heat treated to harden and strengthen the carbon steel material, delivering hardness and durability for longlasting performance. 2) Nonslip Handle Design: The knurled round shank provides a secure, nonslip grip, enabling precise control and safer handling during use. 3) Tapered Punch Point: The punching tip features a dimple to create an exact starting spot, reducing wandering and ensuring accurate drilling every time. 4) Compatibility: This hole drilling positioner works effectively on cast iron, mild steel, brass, bronze, copper, aluminum, wood, plastics, and polymers, offering versatile use across materials. 23 practical use scenarios Metalworking: Begin a drill hole in cast iron or mild steel with confidence by starting at a precise point, then proceed with drilling to reduce drift and improve hole accuracy. Wood and plastics: Use the dimpled starting point to prevent drill wandering on wood or plastic components during alignment or assembly tasks. Assembly and fixtures: Utilize the positioner to accurately start and align holes across multiple parts and materials (including aluminum, brass, or polymers), improving fit and reducing rework.
