What's the difference between a UC drill and an ST bit?
UC bit is used for high quality drilling, drilling temperature is low, less nail head, slag, broken rate phenomenon. Because of its low loss ratio, the drilling torque resistance is reduced, which is beneficial to micro drilling and more than 6 layers of PCB boards.
The ST drill is easy to operate, easy to control diameter, more grinding times, and its range of use is relatively large. It can be used in general use, which is beneficial to general diameter drilling and double face plate and more than 6 layers of panels.
