[0002] Deep hole drills are used to introduce bores into workpieces. Different types of deep hole drills are specified in VDI guideline VDI 3210. Deep hole drills are mainly used to produce bores with relatively small diameters, which are mainly in the range of 0.5 mm to 50 mm, wherein the drilling depth can be a multiple of the bore diameter. Conventional values ​​for the drilling depth are in the range of 20 to 100 times the bore diameter, but can also be higher or lower than this figure.

[0003] After checking the announcement number: CN209736717U, a deep hole drill is disclosed. This technology discloses "including: a cutting tool, a drill rod, and a drill shank, the diameter of the drill rod is smaller than the diameter of the cutting tool, the lower end of the drill shank is connected to the upper end of the drill rod, the lower end of the drill rod is connected to the upper end of the cutting tool, and at least one guide boss is protrudingly formed on the circumferential outer surface of the drill rod, and the diameter of the guide boss is the same as the diameter of the cutting tool, etc. The technical scheme has a guide boss arranged on the outer side of the drill rod, so that in the process of deep hole drilling, the mutual cooperation between the guide boss and the inner wall of the drilled deep hole can be utilized, and the friction between the extremely small contact surface of the guide boss and the hole wall can be utilized to achieve the effect of straightening the drill rod and improving the drilling accuracy, and at the same time, the friction between the large area of ​​the drill rod and the hole wall and the adverse effects such as swinging caused by the excessive length of the drill rod are avoided, thereby improving the quality and accuracy of the drilling and other technical effects".

[0004] With respect to the above-mentioned related technologies, the inventors believe that when the deep hole drills in the prior art are in use, most of the deep hole drills cannot limit and fix the connection well, which causes the deep hole drills to become loose during use, thereby causing the deep hole drills to fall off easily during operation.
