Frequently Asked Questions (FAQs)

1. Are spiral flute taps better?

Yes, spiral flute taps are considered better because the spiral fluting feature helps evacuate chips out of the tapped hole. They are particularly recommended when dealing with gaps inside the hole, such as keyways or cross-holes.

2. What is a spiral flute tap used for?

A spiral flute tap is primarily used for tapping threads in blind holes. The flutes of the tap wrap around its axis in a spiral or helical configuration. This design allows the tap to pull chips out of the hole towards the tap shank, opposite to the tapping direction.

3. Can you hand tap with a spiral flute tap?

Yes, spiral flute taps can be used for hand tapping. They are generally easy to use by hand, especially for smaller sizes up to around M6. However, it may become more challenging to hand tap with larger sizes. Spiral flute taps are particularly useful for threading depth in blind holes, as they only cut on the first few threads.

4. What is the advantage of helical fluted taps?

Helical fluted taps are designed to provide a lifting action to remove chips. They are especially recommended for materials that tend to produce stringy chips. High helix taps excel at tapping deep blind holes in ductile materials, as they offer exceptional lifting action.

5. What is the strongest type of tap?

The strongest type of tap is the spiral-point tap. It has straight flutes like a hand tap, but with a left-handed spiral near the point. This spiral shears off the chips and shoots them forward in front of the thread being produced. Spiral-point taps are the most effective chip-cutting taps and should only be used in through-holes.

6. When should a spiral point tap be used?

Spiral point taps, also known as "gun taps," are particularly useful for clearing chips ahead of the cutting edge and pushing them out the other end of the hole. They are highly effective for deep hole tapping, making them a preferred choice in such applications.
