High-speed scale scrap drill bit

Abstract

Disclosed is a high-speed scale scrap drill bit. The high-speed scale scrap drill bit comprises a drill bit body provided with upright-shaped cutting edges. The cutting edges are provided with a scrap breaking cutting opening which is formed by the two cutting edges in a mutually intersecting mode. The scrap breaking cutting opening is of an asymmetrical and inclined structure. A cylindrical connection handle is arranged behind the drill bit body. The cutting edges are arranged to be in the upright shape so that the drilling ability of the drill bit can be enhanced, and the machining strength of the drill bit is promoted. The cutting edges are provided with the scrap breaking cutting opening so that scrap iron can be cut off and removed conveniently, and accordingly the scrap iron is prevented from blocking a machining hole. Therefore, the next step of machining can be conducted smoothly through the drill bit, and the machining efficiency of the drill bit is improved. A transition component is provided with locating pins so that the drill bit can be located on a drilling machine more firmly. The locating pins are provided with abrasion-resistant layers, so that the abrasion resistance of the locating pins is promoted, and accordingly the locating pins are located in locating holes more firmly.

Description

technical field [0001] The invention relates to a drill bit, in particular to a high-speed chip drill bit. Background technique [0002] In the production process of the workpiece, it is often necessary to drill holes on the workpiece. When drilling, it is often applied to the drill bit. The use of the drill bit often requires chip removal, but many drill bits are often unable to remove the iron filings at the end of the drilling. It is brought out, so that the iron filings accumulate in the drilling, which affects the next step of drilling. In the actual drilling, the drill bit will also encounter serious wear of the positioning pins. Many positioning pins must be severely worn when they are in use. , it will lead to unstable positioning of the drill bit. When connecting with the machine tool, the positioning pin will not be able to be smoothly inserted into the positioning hole. The actual processing accuracy of the drill bit cannot successfully complete the processing ta...
