In machining, due to the different diameters of the drill holes, it is sometimes impossible to directly match the drill bit to the tailstock or the drill hole of the drill press. It is necessary to work with the drill sleeves of different specifications, but only the entire machine can be loaded and unloaded (Fig. 1). The current common method of disassembly is to use a diagonal iron to tap on the ground. The main disadvantages are: 1 It is easy to damage the surface of the drill bit and the drill sleeve, resulting in poor fitting and affecting the drilling accuracy. 2 It is easy to hurt your fingers. To this end, we have designed the simple and practical unloading sleeve or drill tool shown in Figure 2.
