1、Premium Material: High‑speed steel taps are with high hardness and wear resistance. Uncoated taps have only a basic substrate without any additional coatings, and fit a wide range of applications. 2、Function: There are a total of two taps to facilitate the alignment of the tap and the tapping hole to ensure that the tap and the hole are perpendicular to each other and tapping smoothly. It also has a smoothing effect on the thread (removes burrs). 3、Standard Thread: Standard metric thread design, clear and tidy, provide rapid chip removal for efficient threading. Can make new threads or re‑thread damaged or jammed threads. 4、Wide Application: Suitable for most metals, iron plate, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, etc. Appropriate addition of coolant (e.g. water) can extend the service life when tapping. 5、Applicable Industry: The mini metric taps are mainly used for clocks, watches, low hardness wood and soft metal hole processing. Mainly used for
