Taps and dies are essential tools used in machining and metalworking to create internal and external threads, respectively. Taps are designed to cut internal threads in pre-drilled holes, allowing for the insertion of screws or bolts, and feature sharp, spiral flutes to remove metal shavings while cutting. In contrast, dies are cylindrical tools used to create external threads on rods or bolts, shaping the material as they are turned. Both taps and dies come in various sizes and thread types (e.g., UNC, UNF, metric) to accommodate different applications. Often sold in sets that include multiple sizes along with a tap wrench and die stock, these tools are crucial for ensuring secure fastening and assembly in industries such as automotive, plumbing, and construction.
