Tap and Die are cutting tools used in machining to create screw threads.
• Tap: A tap is used to cut internal threads inside a hole (like the threads inside a nut). It is usually made of hardened steel and has flutes that help remove metal chips while cutting. Taps are used with a tap wrench or machine.
• Die: A die is used to cut external threads on a cylindrical rod or bolt (like the threads on a screw). It also has cutting edges and openings to allow chips to escape. Dies are held in a die stock during use.
Uses:
Tap and die sets are commonly used in workshops, fitting shops, and maintenance work for making new threads or repairing damaged ones.
