Product Description:
The drill body serves as the principal structural component of a drill bit, responsible for supporting the cutting section, transmitting drilling force, and aiding in chip removal while in operation.
Typically, it incorporates various elements such as flutes for facilitating chip evacuation, margins for providing guidance, and a core for enhancing strength. Certain designs may also feature coolant channels aimed at enhancing drilling efficiency and prolonging tool life.
Typical materials used for constructing the drill body include high-speed steel (HSS), carbide, and coated alloys. Its critical role lies in ensuring stability, precision, and effectiveness throughout the drilling processes.
Features:
