Abstract

The invention discloses a novel medical step drill bit composed of a drill point, a main drill body and a drill handle. The novel medical step drill bit is characterized in that the main drill body is of a step cylinder structure, the large-diameter end of the main drill body is connected with the drill handle, the connecting mode of the main drill body and the drill handle is integrated forming, the small-diameter end of the main drill body is connected with the drill point, the drill point and the main drill body are integrally formed, and a positioning groove is formed in the position, close to the tail end, of the drill handle. According to the medical step drill bit, the main drill body of the step cylinder structure and the positioning groove are combined, and in the medical drilling process, the advantage of one-drill for multiple holes can be achieved.

Description

technical field [0001] The invention belongs to the field of medical drill bits, in particular to a novel medical step drill bit. Background technique [0002] The drill bit is a tool that rotates and has cutting ability at the head end. It is generally made of carbon steel SK, or high-speed steel SKH2, SKH3 and other materials by milling or rolling, then quenching, tempering and heat treatment. Or drilling on other materials, it can be used in a wide range of tools and machines such as drilling machines, lathes, milling machines, and hand drills. [0003] The drill bit is a tool used to drill through holes or blind holes in solid materials, and can ream the existing holes. Commonly used drills mainly include twist drills, center drills, flat drills, deep hole drills and nesting drills. Although countersink drills cannot drill holes in solid materials, they are also classified as drill bits by convention. During digging, the drill bit rotates with the vertical shaft and m...
