BAER HSS Mini Tap Form C - M 0.9 x 0.225
BAER HSS Mini Tap Form C - M 0.9 x 0.225
If you want to build something that is small and delicate, you will need an extremely small screw connection, also called a miniature thread. The bore must be adapted for this. The miniature screw tap from BAER with a nominal diameter of 0.3 to 2.0 millimetres are the solution. Whether by hand or semi-professionally by machine, this mini internal tap with full thread profile cuts precisely and straight into the core hole - an absolute must when cutting threads. These mini taps are often used in industrial manufacturing on automatic lathes and thread cutting machines because they have high efficiency and low production costs.
Cutting such a small thread can quickly become challenging because guiding the mini tap is very difficult. For ideal guidance, it is recommended to use a drill stand or a tapping machine.
