Taps and dies are precision tools used to create screw threads, which are essential for threaded fasteners. A tap is used to cut internal threads inside a hole, allowing a bolt or screw to be inserted. It works much like a drill bit, but instead of creating a smooth hole, it carves the spiral grooves (threads) into the material. Taps are commonly used when creating threaded holes in metal or plastic components.
A die, on the other hand, is used to cut external threads onto a cylindrical rod, effectively turning it into a screw or bolt. The die is typically a hardened steel disk with cutting edges on the inside, and it is rotated around the rod to form the threads.
Together, taps and dies are essential tools in machining, repair, and fabrication work, enabling the creation or restoration of both internal and external threads with precision.
