Abstract

The invention discloses a drill. The drill comprises a drill assembly and a pipeline assembly. The drill assembly comprises a fixed post, a first grinding portion, a second grinding portion, a cuttinghead and water outlets, wherein the fixed post is arranged on the upper surface of a drill handle and fixedly connected to the drill handle, and the first grinding portion is arranged on the lower surface of the drill handle and fixedly connected with the drill handle. After a user fixedly connects the whole drill assembly with a drill machine, cooling liquid is fed into cylindrical water inlet pipes from water inlets through a high pressure water injector and then flows through curved type water inlet pipes, the interior of the first grinding portion and the interior of the second grinding portion are cooled conveniently, finally the cooling liquid is sprayed out of the water outlets in the lower end face of the cutting head, and the cutting head is cooled; and meanwhile, dust generateddue to cutting can be humidified, and thus dust raising is avoided, and the personal safety of the user is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of drill bits, in particular to a drill bit. Background technique [0002] With the continuous advancement of science and technology, drill bits have developed from the initial drilling work to drilling wood, diamond heads and metal drilling holes. It is very convenient, but because the drill bit is easy to generate high heat during work, people need to cool the drill bit in the process of using the drill bit. [0003] Most of the methods that people cool the drill bit now are to open a cylindrical water spray pipe in the drill bit, and the water spray pipe directly reaches one side of the drill bit head. Shape, so that the body of the drill bit is not easy to cool. Contents of the invention [0004] The present invention provides a drill bit, aiming at solving the problem that most of the current methods for cooling the drill bit are to open a cylindrical water spray pipe inside the drill bit, and the w...
