Set of 2 metric taps for clocks, watches, wood and soft metal (M4 x 0.7).

1. Premium Material: High-speed steel taps offer high hardness and wear resistance. Uncoated taps have only a basic substrate without any additional coating and are suitable for a wide range of applications. 2. Function: There are two taps to facilitate alignment of the tap and tap hole, ensuring they are perpendicular to each other and tap smoothly. This also smooths the thread (eliminating burrs). 3. Standard Thread: Standard metric thread, clear and neat, allows for quick chip removal for efficient threading. Can repair damaged or stuck new or re-threaded threads. 4. Wide Application: Suitable for most metals, including iron plates, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, etc. Proper addition of coolant (e.g., water) can extend tap life. 5. Applicable Industry: Mini metric taps are mainly used for clocks, watches, soft wood, and processing soft metal holes. They are primarily used for hand tapping, tapping the vast majority of materials in through-hole applications. Specifications: Item Type: Threaded Tap; System: Metric; Number of Threads: 3; Thread Tolerance Level: 0.014; Through Hole/Blind Hole: Through Hole; Material: High-speed steel; Tap Style: Straight groove; Thread Code: Standard thread; Application: Suitable for thick steel, rubber, aluminum, copper, and wood. Instructions: 1. There are 2 taps in a set, which can also be divided into first and second taps. 2. Function of the first tap: The front part of the first tap has a cone that is shallow and has no threads, making it easy to align the tap with the tapped hole to ensure it is perpendicular to the hole and allows for smooth tapping. 3. Function of the second tap: In addition to preparing the first tap's margin to meet the standard, it also plays a role in cutting the thread (removing burrs). For blind threads
