Note: the process must be constantly added with water, and water is added while working. Since the hole opener does not have a central drill, it is necessary to slowly contact the material at an oblique angle of 45 degrees during operation, and after opening a moon groove, it can play a positioning role, then the vertical drill is drilled by the electric drill. Be sure to slow down when you're about to drill. The larger the hole opener, the slower the speed should be. Stop working when chip removal is not ideal, then work after cleaning.
