This 3-piece VÖLKEL tap set allows you to cut precise and easy metric threads. As a classic hand tap M 4, the set consists of a taper, intermediate, and bottoming tap, which are perfectly matched to each other. With this versatile thread cutter from VÖLKEL, you can cut threads in soft to medium-hard materials. It is the ideal thread cutter for anyone who values quality and clean results.
Q: Why does the set consist of three taps?
A: The 3-piece set is designed for hand use. It distributes the cutting load among three tools, which makes cutting easier and increases the tool life of each individual tap. The taper tap starts the cut, the intermediate tap deepens it, and the bottoming tap brings it to the final shape and exact dimension.
Q: What does the tolerance ISO 2 / 6H mean?
A: The tolerance class ISO 2 / 6H is the standard tolerance for metric ISO threads. It ensures that the cut thread is precise enough for most general applications and that common screws will fit the thread.
Q: What is the difference between an HSS-G and an HSS-E tap?
A: HSS-G stands for "High Speed Steel - Ground." The material is ideal for easily machinable steels. HSS-E also contains cobalt, which increases hardness and heat resistance, making it suitable for harder or stainless steels.
Q: Is this tap set suitable for blind holes?
A: Yes, the set is specifically designed for hand use in both through and blind holes. The three-piece set allows for a step-by-step process, so the thread can be cleanly cut to the bottom of the blind hole.
Q: What is the recommended torque?
A: The recommended torque depends heavily on the material and the lubricant. Since this is a hand tool, feel is crucial. Pay attention to the resistance when turning. If the resistance increases sharply, turn the tool back slightly to break the chips, and then continue the cut.
