It refers to a specific type of punch die used for shaping or forming cardboard targets in target shooting applications. The punch die is made of tungsten steel, a material known for its high strength, hardness, and wear resistance. It is designed to create precise and consistent shapes in cardboard targets used for shooting practice or competitions.
The key specifications of a tungsten steel punch die for forming cardboard targets can vary depending on the specific requirements of the target shooting application.

However, here are some common specifications:
Size: The size of the punch die can vary based on the desired dimensions of the cardboard targets. It typically includes the outer diameter or length and width dimensions, which determine the overall size of the target.
Shape: The punch die is designed to create a specific shape in the cardboard targets. This can include various shapes such as circles, squares, rectangles, or custom shapes depending on the shooting requirements or regulations.
Tolerances: Tolerances define the allowable deviation from the desired dimensions of the punch die. Tolerances for a tungsten steel punch die are typically kept tight to ensure accurate and consistent target formation. The specific tolerances depend on the precision requirements of the target shooting application.
Cutting Edge: The punch die will have a cutting edge or profile that corresponds to the desired shape of the cardboard target. The cutting edge is carefully designed to produce clean and precise cuts in the cardboard material.
Hardness and Wear Resistance: Tungsten steel is chosen for its high hardness and wear resistance properties. The punch die should have a high Rockwell hardness to withstand the punching forces and maintain its cutting edge over an extended period. The wear resistance ensures durability and longevity of the punch die.
Surface Finish: The surface finish of the punch die should be smooth and free from defects to minimize friction and ensure clean cutting action. A polished or coated surface may be applied to further enhance the performance and lifespan of the punch die.
It's important to note that the specific size, shape, tolerances, and other specifications of a tungsten steel punch die for forming cardboard targets can be customized based on the unique requirements of the target shooting application.
