In addition to Nut Taps, there are a few other types of taps commonly used for threading fasteners. These taps are designed for different applications and offer specific benefits. Here are some examples:
Bottoming Taps: Bottoming Taps, also known as Plug Taps, have a shorter chamfer length compared to standard taps. They are used for threading blind holes where the tap needs to reach the bottom of the hole. Bottoming Taps have a flat or slightly rounded tip, allowing them to thread close to the bottom without excessive chip accumulation.
Taper Taps: Taper Taps have a longer chamfer length and a more gradual taper compared to other taps. They are used for starting threads in through-holes or when easy alignment is required. Taper Taps help guide the tap into the hole and gradually cut the threads, making them suitable for both hand and machine threading operations.
Spiral Point Taps: Spiral Point Taps, also called Gun Taps or Chip Taps, have a pointed end with a spiral flute design. The spiral flute pushes the chips forward, allowing for efficient chip evacuation. Spiral Point Taps are commonly used in high-volume production for through-hole threading applications.
Roll Taps: Roll Taps, also known as Thread-Rolling Taps or Thread-Forming Taps, are designed for creating threads in ductile materials like aluminum, copper, and brass. Instead of cutting the threads, Roll Taps displace the material to form the thread. This process provides stronger threads and improved resistance to stripping.
Interrupted Thread Taps: Interrupted Thread Taps are specialized taps used for threading fasteners with interrupted threads, such as helical coil inserts or helicoils. These taps have a specific flute design that allows them to thread into the helical coil insert, ensuring proper engagement and secure fastening.
It's important to select the appropriate tap type based on the specific threading requirements, material being threaded, and the type of fastener being produced. Considerations such as hole depth, thread engagement, material hardness, and production volume should be taken into account when choosing the right tap for threading fasteners.
