The tools are precision machined to produce accurate threads, ensuring a tight and secure fit when used to tap holes. 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. 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. The thread taps are made of 9CrSi alloy tool steel with high hardness, wear resistance and toughness, durable and very suitable for tapping hard materials. Tapping oil has lubrication, cooling and anti-sticking effects. Adding appropriate tapping oil can obtain higher quality internal threads and more durable taps. Please apply anti-rust oil for maintenance after use to extend the service life. 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.
