AI Technical Summary

Technical Problem

The existing drill bits have severe wear due to waste chips during the drilling process, short service life, and low drilling efficiency due to few contact points.

Method used

A drill bit cutter with teeth and chip drainage groove is designed. The main body of the knife head is a bullet-shaped cross-shaped shape, the bottom is connected to the top of the drill head, several teeth are arranged on the edge of the blade, and chip drainage grooves are arranged on the side of the blade.

Benefits of technology

By increasing the contact point of the teeth, the pressing pressure on the plate is reduced and the drilling efficiency is improved. The chip drainage groove effectively discharges waste chips during drilling, reducing the loss to the cutter head and extending the service life.

Abstract

The utility model relates to a drill bit tool bit with teeth and chip grooves. The drill bit tool bit comprises a tool bit body, the teeth and the chip grooves. According to the drill bit tool bit with the teeth and the chip grooves, when the drill bit tool bit works, after the tool bit drills into a plate, the number of contact points between the teeth and the cutting face of the plate can be increased through the teeth, and therefore more labor is saved, and the drilling efficiency is higher; the chip groove formed in the side face of the tool bit can discharge waste chips generated during drilling, loss of the tool bit caused by the waste chips is reduced, and the service life is prolonged.

Description

Technical Field

[0001] The utility model relates to a drill bit tip with teeth and chip removal grooves, belonging to the technical field of hand tools. Background Art

[0002] During the process of daily construction or decoration, it is extremely common to drill holes in tiles, cement, stone, metal, plastic, wood, etc. During the drilling process, it is necessary to rely on the sharp tip of the drill bit tip to cut and drill various plates. The waste chips generated during the drilling process cause serious wear of the tip and short service life. At the same time, because the drill bit tip mostly relies on one or several contact points at the top to cut the plate, more pressing force is required during work, resulting in relatively low drilling efficiency. To solve this problem, we provide a drill bit tip with teeth and chip removal grooves. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a drill bit tip with teeth and chip removal grooves.

[0004] The technical solution of the utility model is as follows:

[0005] A drill bit tip with teeth and chip removal grooves, comprising a tip body, teeth, and chip removal grooves; the tip body is in the shape of a bullet-shaped cross, and the bottom is connected to the top of the drill bit to form an integral body; several teeth are arranged on the blade edge of the tip body; chip removal grooves are arranged on the blade side of the tip body.

[0006] Preferably: the tip body is flat, with a sharp top, curved sides, and the bottom is connected to the top of the drill bit to form an integral body; several teeth are arranged on the blade edge of the tip body; chip removal grooves are arranged on the blade side of the tip body.

[0007] Preferably: the tip body is flat, with a sharp top, the upper parts of both sides are inclined planes and the lower parts are straight planes, and the bottom is connected to the top of the drill bit to form an integral body; several teeth are arranged on the blade edge of the tip body; chip removal grooves are arranged on the blade side of the tip body.

[0008] Preferably: the tip body is flat, with a flat top, the upper parts of both sides are inclined planes and the lower parts are straight planes, and the bottom is connected to the top of the drill bit to form an integral body; several teeth are arranged on the blade edge of the tip body; chip removal grooves are arranged on the blade side of the tip body.

[0009] Preferably: the tip body is flat, with an inclined top, the upper parts of both sides are inclined planes and the lower parts are straight planes, and the bottom is connected to the top of the drill bit to form an integral body; several teeth are arranged on the blade edge of the tip body; chip removal grooves are arranged on the blade side of the tip body.

[0010] The beneficial effects of the present utility model are as follows:

[0011] For a drill bit tip with teeth and chip grooves, when the tip drills into the board during operation, several teeth provided can increase the contact points with the cutting surface of the board, thus making it more labor-saving and having a higher drilling efficiency; the chip grooves provided on the side of the tip can discharge the waste chips generated during drilling, reduce the wear on the tip caused by the waste chips, and increase the service life.
