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.
