Abstract

The invention relates to the technical field of drill bit buried hole drilling, and discloses a buried hole drill bit. The buried hole drill bit comprises a center rod and a drill bit body, the center rod and the drill bit body are coaxial, the center rod is clamped in the middle of the drill bit body and plays a role in positioning and guiding, a cutter is arranged at the end of the drill bit body, and the inner diameter of the cutter is matched with that of the drill bit body. A centrifugal weight is arranged behind the cutter, the centrifugal weight and the drill bit body are integrally formed, the buried hole drill bit penetrates into an original drilled hole, the buried hole drill bit rotates at a high speed during working, the center rod prevents a drilling angle from deflecting, and the centrifugal weight generates centrifugal force to enable the drill bit body and the center rod to be separated. The cutter is used for expanding and drilling an original hole diameter, the cutter is only used for expanding and drilling, and the requirement for the strength of the cutter is not high. According to the buried hole drill bit, the structure is simple, the working efficiency is high, the cost is low, a drilled hole can be used for machining a buried hole in a drilled through hole or blind hole, and the buried hole drill bit has the advantages that the hole burying cost is reduced, and the drill bit is richer in function.

Description

technical field [0001] The invention relates to the technical field of drill bit buried hole drilling, in particular to a buried hole drill bit. Background technique [0002] At present, plate products of various materials are a type of product with a very large demand in the market. It is very necessary to process various holes on the plate. Usually, the holes that can be processed directly and conveniently with a drill are mainly through holes. , Blind holes, etc. These holes can meet the production and processing needs of most products, and the buried hole technology is mainly used to drill concentric and large inner diameter holes in the through holes or blind holes that have been processed on the plate. Holes and buried holes also have important applications in board installation and connection. [0003] However, the buried hole processing technology is not universal at present. Expensive machines such as laser drilling machines and electroplating hole-making equipment...
