Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
As shown in fig. 1-4, a spiral alloy drill comprises a drill bit 1, a drill body 2 and a drill tail 3, wherein an oil inlet 4 is arranged in the middle of the drill bit 1, the oil inlet 4 is communicated with an oil outlet 5 for oil outlet, a connecting hole 6 is arranged on the drill body 2, and the connecting hole 6 is connected with an oil inlet device 7.
Wherein, the oil outlet 5 is provided with a plurality of. The oil outlets 5 uniformly discharge oil, so that the lubrication of the drill bit 1 is uniform, and the local deformation of the drill bit 1 caused by high local temperature is reduced.
The oil inlet device 7 includes an oil inlet plate 71. The oil inlet plate 71 is provided with a connecting device 8 at one side for fixing the oil inlet plate 71 to the drill body 2. The oil inlet plate 71 is slidably disposed through the drill body 2.
