How to Choose the Right Thread Taps?

2025-04-15

Thread Taps are important manufacturing tool used to form threads on drilled holes to accept the corresponding bolts or screws.

Thread Taps

1. Choose according to the type of material. First, consider the workpiece material that needs to be tapped. Choose Thread Taps made of this material so that the workpiece material can be processed. There are three types of tap materials: high-speed steel, carbide, and carbide with nitride coating. High-speed steel is suitable for soft materials such as aluminum and thermoplastics, while you need a carbide tap with nitride coating to cut threads in hard materials such as titanium and hardened steel.

2. Match with the required pitch

The pitch refers to the spacing between threads. It is one of the most important parameters that define the characteristics and fit of the thread. Therefore, choosing the type of Thread Taps requires considering the required pitch size and looking for the right tap size that can achieve that pitch size.

3. Determine blind hole or through hole

Check the type of hole you are tapping, blind hole or through hole. Chip evacuation is not a problem for through holes, while blind holes require upward chip evacuation to avoid clogging and heat damage. For blind hole threads, you can choose between spiral tip, base, spiral groove.

4. Consider the groove requirements

Grooving requirements usually involve how many grooves you need to get better tapping results. Depending on the type of thread tap, they may contain 2, 3, 5, 7, 10 or more grooves. Tools with fewer grooves are suitable for hard materials and blind holes. On the other hand, more grooves increase speed and are best for through holes.

The right Thread Taps depend on the material, hole type, thread size and geometry, and the precision required for a perfect fit during assembly. In addition, the quality of the Thread Taps will also affect the results.
