Embodiment Construction

[0012] A multi-channel chip removal drill bit according to the present invention has a structure as shown in the figure: the main body is a drill bit body, and the drill bit body is integrally formed by a drill bit 1 and a drill body 2. Its innovative points are:

[0013] The structure of the drill bit 1 is a cone, the tip of the drill bit 1 is designed as a plane end with a length of 0.5-1.5cm, and the cone is provided with a spiral groove 1a; and on the center line of the drill bit 1 A through hole 1b with a diameter of 1 cm is provided along the axial direction. The design is a flat end to reduce the excessive pressure of the drill bit at the moment of drilling, which will cause damage to the drilled object; the spiral groove 1a is used for chip removal; because it is a flat end, only the spiral groove is used for chip removal 1a is not enough, this design has a through hole 1b on the center line to assist in chip removal.

[0014] The drill body 2 of the present invention...

Abstract

The invention discloses a drill bit capable of performing multichannel chip removal. A main body is a drill bit body. The drill bit body is integrally formed by a drill bit and a drill body. The drill bit is characterized in that the drill bit is structurally a cone, a tip part of the drill bit is designed into a plane end with the length of 0.5-1.5 cm, the cone is provided with a spiral groove, and a through hole is formed in the center line of the drill bit in the axial direction. The drill body is a two-stage step type cylinder, a groove is formed in one stage of the cylinder in the circumferential direction to divide the cylinder into two sections, and each section is internally provided with a long hole. The multichannel chip removal is adopted by the drill bit, a conical spiral drill bit structure is combined; during the drilling through the drill bit, a chip removal channel is divided into a spiral chip removal mode and a straight channel chip removal mode, chip removal channels are effectively dredged, and the problem of difficulty in chip removal is solved.

Description

technical field [0001] The invention relates to a hole drill bit, in particular to a multi-channel chip removal drill bit. Background technique [0002] As an essential tool for drilling, the drill bit is a common tool for engineers; there are many types of drill bits, they are widely used, and there are many types of drill holes. Due to the drilling requirements according to the requirements of the hole type and the requirements of the plate, there are different design requirements for the drill bit. Various forms. At present, although there are many drill bits on the market, there is no drill bit with multi-channel chip removal. Contents of the invention [0003] The present invention mainly provides a multi-channel chip removal drill bit, which solves the problem of poor chip removal in holes. [0004] In order to solve the above technical problems, the present invention provides the following solutions: [0005] A multi-channel chip removal drill, the m...
