ERG tapping collet is a necessary tapping chuck for the tapping tool holder. ERG tapping collet is made of high-quality elastic steel, which improves the surface hardness and wears resistance. Repeated loading and unloading do not affect the accuracy. The special surface treatment of “environmental protection” improves the cleanliness, making the surface smoother, more comfortable, and more beautiful. It is widely used in boring, milling, drilling, tapping, grinding, and carving.
