What's the difference between a deep hole drill and an ordinary bit?
Ordinary drills are of relatively low hardness, impact resistance and wear resistance. The drilling accuracy, drilling speed and the drilling speed of conventional drills can not be compared with those of deep hole drilling.
What's the difference between a deep hole drill and an ordinary bit? Concretely speaking:Deep hole drilling is also called carbide gun drill, and most of the materials used are titanium, cobalt and steel. The deep hole drill is welded together by three parts of a drill stem, a drill rod and a drill bit. There is a through hole in the middle. It is suitable for drilling cast iron, carbon steel, copper, aluminum alloy, alloy steel and so on. The gun drill will complete the drilling, boring and reaming at once, and at one time, the high precision (IT6-8 grade), fine straightness (0.16-0.33mm/1000mm) and low roughness (Ra3.2-Ra0.1) holes can be machined. Its drilling speed of 30-100 meters / min..
