【High Performance】These taps are made of high speed steel and nitrile materials, with high hardness and rust resistance, durable and long lasting. Automatic checkpoint: L is not centered or centered. This can quickly save you a lot of time and money. [Wide range of applications] Taps with drilling functions are used to drill holes and cut new threads at the same time. Our drill bits are suitable for drilling machines, cutting machines, automatic machine tools, CNC machine tools, etc. This drill can work with wood, aluminum, titanium and other materials. No friction chips: The tapping tool has a special spiral that can pass through the spiral groove smoothly, making tapping more efficient and improving processing efficiency. 【Stable performance】 The blind thread drill bit leaves no cutting, the drill bit is easier to enter the bottom hole than the M2 tap, and it has good toughness, large cutting amount, scratch resistance, and achieves better results. These pumps are used on machines
