Specifications: Style: Taper Tap Thread Size: 1/4-20 UNC Total Length: 69mm / 2.72" Thread Length: 28mm / 1.1" Square End Width: 5mm / 0.2" Accuracy Class: 2B Cutting Direction: Left Hand Material: M2 / 6542 High Speed Steel (HSS6542) Finish: Uncoated Package Content: 1pcs x Hand Taper Thread TapDescriptions: Taper tap starts the thread and guide it into the workpiece. The straight groove design of the hand tap can quickly remove chips downward, reduce operating resistance, and achieve efficient processing. The thread is clear and burr-free, which can achieve precise tapping. Hand taps are mainly used with tap wrenches and are suitable for re-tapping damaged or stuck threads, or to create new threads. Used for tapping through or shallow holes in mild steels, aluminum, iron, copper, hard plastic. M2 (6542) high-speed steel has high hardness, good wear resistance, is not easy to deform, and has a long service life. It is heat-resistant and maintains stability in high-temperature environments. It is characterized by only a matrix without any coating, and is suitable for general thread tapping. Add appropriate tapping oil for higher quality internal threads and more durable screw taps. Ensure proper alignment, use proper tapping technique, and apply consistent pressure as you turn the tap to achieve clean, precise threads. Periodically reverse while tapping to break up chips and remove debris from the flutes, preventing clogging and ensuring smooth operation. Please apply anti-rust oil after use to extend the service life.
