Abstract

The invention discloses a novel compact drill bit. The novel compact drill bit comprises a drill bit part and a handle part; the handle part is arranged on the upper part of the drill bit part and comprises a first drill bit part, a second drill bit part, a third drill bit part and a fourth drill bit part; the first drill bit part, the second drill bit part, the third drill bit part and the fourthdrill bit part are all provided with compacts correspondingly, and the compacts are arranged to be of a linear structure; and the outer circumferential faces of the first drill bit part, the second drill bit part, the third drill bit part and the fourth drill bit part are each arranged to be of a smooth circular-arc-shaped structure. According to the novel compact drill bit, the problems in the prior art are effectively solved, and the novel compact drill bit has the advantages of excellent abrasion resistance, high practicality and the like; the outer circumferential faces of the first drillbit part, the second drill bit part, the third drill bit part and the fourth drill bit part are each arranged to be of the smooth circular-arc-shaped structure, the abrasion rate of the drill bit isdecreased, and the service life of the drill bid is prolonged; the impact resistance ability is high; and the manufacturing cost of the novel compact drill bit is economic and reasonable, and the novel compact drill bit is suitable for being used and promoted socially.

Description

technical field [0001] The invention relates to a drill bit, in particular to a novel composite sheet drill bit. Background technique [0002] PDC drill bit is the abbreviation of polycrystalline diamond compact drill bit. It is a drilling tool commonly used in the geological drilling industry. The drill bits used in the prior art have poor wear resistance, poor impact resistance, and poor wear resistance, which reduces the service life of the drill bit and increases the cost; therefore, a new type of composite drill bit has become an urgent problem for the entire society. Contents of the invention [0003] The technical problem to be solved by the present invention is that the impact resistance and wear resistance of the prior art are poor, which reduces the service life of the drill bit and increases the cost. [0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a new type of composite drill, including a ...
