[0003] For example, announcement number CN219966536U discloses a step drill, which has a first and a second step portion, and the step lengths between the first and second step portions are different. The length of the first step of the first step portion is smaller than the length of the second step of the second step portion, so that when the first step portion is used, it is possible to transition from a smaller diameter to a larger diameter in a shorter time; for example, announcement number CN220805599U discloses a step drill, in which both the first drill body and the second drill body have reverse chamfers, the front end of the first drill body is provided with an R-shaped chisel edge, the spiral groove extends from the drill tip of the first drill body to the end of the second drill body, and both ends of the neck are reinforced.
