Product Selection Differences for Taps, Thread Cutting, Machine, Taper

When selecting taps for various applications, it's essential to consider the type of tap that best suits your needs. Here are the key differences among taps:

  1. Taper Taps (also known as Starting Taps):

    • Taper taps have a gradual cutting profile that allows for easier alignment when starting the tapping process.
    • They are generally used to thread the inside of a hole, known as a blind hole, where the tap does not need to go through the full depth of the hole.
    • Taper taps have a lead of 8-10 threads, so they are not suitable for cutting threads close to the bottom of a blind hole.

  2. Plug Taps (also known as Intermediate Taps):

    • Plug taps have a more aggressive cutting profile than taper taps and are used to cut threads in through holes or to the bottom of blind holes.
    • They are suitable for general-purpose threading applications.

  3. Bottoming Taps (also known as Finishing Taps):

    • Bottoming taps have a very short lead, almost flat at the tip, and are used to thread the full depth of a blind hole or to create threads at the bottom of a through hole.
    • They are used for precision threading applications where the full depth of the hole needs to be threaded.

  4. Thread Cutting Taps:

    • Thread cutting taps require more torque to cut threads as they do not remove material but deform it to create threads.
    • They are used for creating stronger threads compared to thread forming taps but produce more waste material.

  5. Thread Forming Taps:

    • Thread forming taps work by displacing material to form threads rather than cutting them, resulting in stronger threads and longer tool life.
    • They are commonly used in applications where it is important to avoid chips and achieve higher thread quality.

  6. Machine Taps:

    • Machine taps are designed for use in machine environments, offering higher cutting speeds and feed rates compared to hand taps.
    • They are available in various designs, including spiral flute taps for deep blind holes and spiral point taps for through holes.
    • Machine taps are commonly used in automated or CNC equipment for efficient mass production.

Consider your specific requirements, such as hole depth, material type, thread accuracy needed, and production volume, to select the most suitable tap for your application.
