Description

Technical Field

[0001] The utility model belongs to the technical field of drill bits, and in particular relates to a drill bit capable of improving drilling efficiency. Background Art

[0002] A drill is a tool used to drill through holes or blind holes in solid materials and to expand existing holes.

[0003] The existing drill bit currently has a large friction with the workpiece, resulting in large wear and tear, which affects the stability of drilling and the service life of the drill bit. At the same time, since the existing drill bit only contacts the workpiece through the cutting edges on both sides, the drilling efficiency is low. Utility Model Content

[0004] The utility model aims to provide a drill bit which can improve the drilling efficiency, so as to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a drill bit capable of improving the drilling efficiency comprises a connecting rod, a drill rod is arranged at the bottom of the connecting rod, a punch is arranged at the bottom of the drill rod, and a notch is arranged on the drill bit.

[0006] Preferably, the connecting rod, the drill rod and the punch are an integrated structure.

[0007] Preferably, the punch comprises a drill tip, both sides of the drill tip are provided with side wings, and the cutout is provided on one of the side wings.

[0008] Preferably, the cutout is close to the drill tip.

[0009] Preferably, the incision is a V-shaped structure, and the angle of the incision is 5-15°.

[0010] The drill bit of the utility model which can improve the drilling efficiency has the following advantages:

[0011] The utility model provides the notches at the flanks of the drill tip, which can increase the number of cutting edges and evenly distribute the cutting force, thereby improving the cutting performance and cutting efficiency of the drill bit, thereby improving the efficiency of drilling holes, and the notches of the drill bit can bring the drill chips out of the bottom of the hole in time, keep the drill bit unobstructed, thereby improving the chip removal ability of the drill bit, and at the same time the notches can reduce the friction between the drill bit and the workpiece, maintain the stable cutting movement of the drill bit, thereby improving the quality and efficiency of drilling holes, reducing the wear of the drill bit, and greatly extending the service life of the drill bit.
