Taps and dies are both tools used for cutting threads on metal surfaces, but they serve different purposes:
- Taps are used to cut internal threads in holes or nuts. They are typically used with a tap wrench to create threads inside a hole or nut so that a bolt or screw can be screwed into it.
- Dies are used to cut external threads on rods or pipes. They are typically used with a die stock or handle to create threads on the outside of a rod or pipe so that a nut or other threaded component can be screwed onto it.
In summary, taps are used to cut internal threads, while dies are used to cut external threads.

Taps
- Used to cut internal threads (in holes) - Three main types: - Hand taps (for manual threading) - Machine taps (for threading on machines) - Pipe taps (for threading pipes) - Typically have a tapered or spiral flute design to guide the tap into the hole - Available in various sizes and thread pitches - Requires a tap handle or machine to operate
Dies
- Used to cut external threads (on rods or bolts) - Two main types: - Hand dies (for manual threading) - Machine dies (for threading on machines) - Consists of a cylindrical body with cutting threads on the inside - Requires a die stock or machine to hold and operate the die - Can be adjustable to accommodate different thread sizes and pitches
Key Differences:
- Purpose: Taps create internal threads, while dies create external threads. - Threading Direction: Taps thread into holes (clockwise), while dies thread onto rods or bolts (counterclockwise). - Tapering: Taps often have a tapered section to help initiate threading, while dies are typically cylindrical. - Shape: Taps are primarily cylindrical or conical, while dies are typically cylindrical. - Operation: Taps require a handle or machine to rotate them, while dies are held in a die stock and rotated over the workpiece. - Application: Taps are used in a wide range of industries for creating threaded holes, while dies are primarily used in manufacturing and automotive applications.
