1. Center drill: used for center hole processing.
2. Gun drill: The gun drill can complete hole processing with a depth of 300 times the diameter of the tool through one process. In addition, due to its excellent machining accuracy, gun drills are widely used in various hole machining including small diameter deep holes. Gun drilling realizes deep hole machining by high-pressure injection of cutting fluid from the inside of the tool, usually using a special machine tool called a "deep hole drilling machine".
3. Flat drill: The cutting edge part is a plate-shaped straight edge drill, and the cutting edge is installed on the cutter body when in use.
4. Reaming drill: There is no cutting edge in the center part of the drill bit, which is used for finishing and reaming bottom hole processing after bottom hole processing.
5. Printed circuit board drill (PCB drill): a straight shank drill with different diameters of drill and shank, which is used for processing very small holes such as printed circuit boards of electronic instruments.
