Frequently Asked Questions

Q: What materials can this HSS metric thread tap set cut threads in?

A: These HSS straight flute plug taps are suitable for threading a wide range of materials including aluminum, brass, copper, mild steel, and plastics. High-Speed Steel construction ensures the cutting edges hold up well across these common workshop materials.

Q: What is the difference between a plug tap and a bottoming tap?

A: A plug tap (like this set) features a chamfer on the first 3–5 threads, making it easy to start and ideal for through-holes or moderately deep blind holes. A bottoming tap has minimal chamfer and is used when threads must extend to the very bottom of a blind hole. For most general applications, a plug tap is the standard go-to choice.

Q: Do I need a special tool to use these taps?

A: These taps are compatible with standard tap wrenches (T-handle or double-handle styles) as well as tap holders for drill presses. For the smaller sizes (M2–M3), a T-handle wrench is recommended for better control and to avoid breaking the tap due to over-torquing.

Q: Are these taps sold individually or as a set?

A: Each listing corresponds to a single size tap. You can select the specific metric size you need — M2, M2.5, M3, M3.5, M4, M5, M6, or M8 — from the available options.
