Today, I am very happy to meet many old and new friends asking me about the small core diameter of the hollow bit. Currently, all of our coring bits have a minimum coring range of 12MM and above, while the largest ones are used for magnetic seat drills with a bit aperture of 160MM. If the hole is too small, I recommend using ordinary twist bits instead. Why can't coring bits be made relatively small? **, small hole holes, ordinary twist drill has been able to deal with very well. In contrast, twist drills cost much less than hollow drills, so the smallest hole size of our plate drills need not be as small. And why do we make rail drills? In fact, it is in order to solve our twist drill in opening large holes encountered large resistance and research and development, so as long as we understand this, we also understand that the main use of the core drill is actually twist drill can not solve the large aperture. In fact, there is another important reason, that is, the smaller the aperture, but we have higher requirements for the three blades at the front of the coring bit, so the production cost is correspondingly increased, compared with the twist bit, it is certain to choose the twist bit. The quality of imported magnetic drill, we will discuss next time. If you don't understand anything, please contact the relevant technical personnel in time.
